Running A Full Node - Bitcoin

Bitcoin-qt dies with "bus error" in the terminal while verifying block index

It's what the tin says. I try to start up bitcoin-qt and it kills itself. Says "bus error" when run in the terminal. Closest thing I can find online is this: https://bitcointalk.org/index.php?topic=766150.0
EDIT: So I think I fixed it, by disabling all the files in .bitcoin except wallet.dat and /blocks/. The client now has to re-process the blockchain but it´s on the disk still and is returning back to where it was quite quickly.

Is it normal for bitcoin-qt to verify blocks at startup?

This typically takes around 5 minutes on a mechanical drive.

Forgot to upgrade your node? Here's how to get back onto the upgraded BCH network:

These instructions are for those who left old versions (0.20.12 or older) of Bitcoin ABC running through the May 15th, 2020 upgrade. Follow these instructions to get back on the main network.
If you are using bitcoin-qt, follow these steps:
  1. Stop your running node
  2. Delete the list of nodes you have banned: rm ~/.bitcoin/banlist.dat
  3. Download version 0.21.x from https://download.bitcoinabc.org/latest/
  4. Start up the new version (./bin/bitcoin-qt)
  5. Open Help -> Debug window
  6. In the console type reconsiderblock 00000000000000000033dfef1fc2d6a5d5520b078c55193a9bf498c5b27530f7
  7. Wait until your node is on the correct chain. This could take some time if your old node was running for a while, and other nodes banned you on the network. You can check that you are on the correct chain by typing getblockchaininfo and verifying the information with a public block explorer such as https://explorer.bitcoin.com/bch, https://blockchair.com/bitcoin-cash, or https://cash.coin.dance/.

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

Windows
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer.
OSX
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

UPDATED – Groestlcoin Sentinel 3.5.06 (Android)

Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets).
Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet.
Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.

How I synced on a 2013 ultrabook in a few days

Note: I don't know exactly how long it took because I didn't do it in one go. I guess it was like 4,5 days doing it only at night. At some points(2015Q3, 2018Q2) it slows down and ETA goes up to 16 weeks or something.
The main bottleneck is IO. My 2013 mobile i3 has enough processing power to sync, I only used 3 threads and most of the time only one was close to 100%. The two directories that need to be written and read from intensively are chainstate and blocks/index. I pruned to 2GB and chainstate didn't go much over 3GB during the entire process. blocks/index is like 100MB.
The best solution is to move chainstate and blocks/index to a ramdisk. If you don't have enough ram the linux kernel has a thing called zram. Zram creates a compressed swap(cache) file in ram, this effectively increases your ram size at the cost of a bit of processing power and access speed(of the compressed part). On my machine I can net a bit more than 1GB of extra ram. That's right, with linux you can download more ram! The second best solution is to leave chainstate and block/index on a sdd. From what I've tested it should take up between 5 whole days and 2 weeks.
With regards to config, I didn't see much benefit in increasing the db cache over the default 450MB in bitcoin-qt. If I recall correctly, smaller prune sizes make chainstate larger.
After the initial sync keeping up to date is very easy on resources. You can catch up a week in a few minutes. At the moment bitcoind is using 400MB but I'm still working on bringing that number down.
Remember: If you want safety or if you want to help the network you need o run a full node. A full node is a node that verifies all transactions. A pruned node is a full node.
Edit: bitocoind really likes to hover around 400MB, sometimes it gets higher than that, some times it get's lower. A lot of that is data, not code, so if you start running out of ram your OS should drop those pages and get down to 250~300MiB. If you really want the memory to be this low all the time, on linux, you can either: Use cgroups to set the swappiness of the process to 99 so all data gets swapped but not code does; Use systemd and set MemoryLimit=300MiB(for example) so almost all data gets swapped but no code. I don't think any of those options are worth the small setup hassle.

#Reddcoin ($RDD) Core Wallet Release 3.0.1 - PosV v2 SuperMajority Consensus Upgrade at 45.6% - Required Upgrade

Reddcoin (RDD) Core Wallet v3.0.1 - January 09, 2020
Version 3.0.1 is the official release version of Reddcoin Core. It is available for download at Reddcoin Core's Github repository here: https://github.com/reddcoin-project/reddcoin/releases/tag/v3.0.1
This release features PoSV v2.supermajority activation and new staking ruleset (and minor misc fixes). v3.0.1 is still not yet MacOS Catalina compatible. We are still working and should have that fix issued very soon. Sincere apologies to our Mac-using ReddHeads.
It is particularly important that all users upgrade, as once PoSV v2 is enforced, version 4 blocks will be rejected from the network entirely.
Therefore v3.0.1 is a "strongly recommended" update for all users. Note: If you have already installed v3.0.0, this upgrade is not required. If you have not yet upgraded from v2.0.x or earlier, this is a REQUIRED upgrade. Please install the newest version v3.0.1 to avoid losing functionality during supermajority activation of PoSV v2.
Reddcoin Core version 3.0.1 is now available from: https://github.com/reddcoin-project/reddcoin/releases Release Notes are available here and replicated below in this announcement: https://github.com/reddcoin-project/reddcoin/blob/mastedoc/release-notes.md
This is a new major version release of Reddcoin.
Previously, the original and subsequent versions of Reddcoin were taken from a fork of the Litecoin code base.
With the release of Reddcoin V2.0.0, the code was based directly from a fork of Bitcoin. This allows for better source control and feature implementation from upstream changes into the future
With the release of Reddcoin V3.0.0, the PoSV stake reward has been improved to allow for a target 5% network growth, in process re-incentivizing individual network stakers and providing for integrated dev support.
Upgrading to this release is strongly recommended and required for continued operation. Once a supermajority of 90% is reached, old wallets will no longer accept the new v5 blocks.
Please report bugs using the issue tracker at github:
https://github.com/reddcoin-project/reddcoin/issues
How to Upgrade
If you are running an older version of Reddcoin, shut it down. Wait until it has completely shut down (which may take a few minutes for older versions). Run the installer (on Windows) or just copy over /Applications/Reddcoin-Qt (on Mac) or reddcoind/reddcoin-qt (on Linux).
Start wallet. All done!
Reddcoin v3.0.0 introduced an updated PoSV method to better distribute staking rewards and target a overall 5% network growth. Staking and relay policy enhancements 
To implement PoSV v2, Reddcoin Core's block templates are now for version 5 blocks only. When PoSV v2 consensus (Supermajority 9000/10000) is reached, only v5 blocks will be accepted by the network.This equates to approximately 90% of blocks being generated over 1 week period. Status at any time may be viewed in node debug.log

Crypto Faucet I use to store my mined bitcoin on, with 4.08% APR paid daily with accounts over 30k satoshi. Referral link included, I share 50% commissions with my referrals paid every Sunday if you're interested.

My referral link for the aforementioned FREEBITCO.IN: https://freebitco.in/?r=30437643&tag=redditF
I have cross referenced this post on my site: passivecryptoguides.com
Why should you sign on with me? I'm not a one off, you can reach me personally through DM or post comments. I've done most of the leg work, alleviating the trial and error process. Just follow the steps in this guide specifically in sections 7️⃣, 8️⃣, and 9️⃣.
I share 50% commissions, get a kick back on everything you earn weekly.
I trust this site, and personally have 270$ worth of bitcoin in one account with almost 500$ total including two other accounts.
Coming from Cointiply? Well, as a heads up, you're not actually holding any BTC. I suggest what you earn you HODL in FREEBITCO.IN.

1️⃣GENERAL INFO1️⃣
FREEBITCO.IN can be accessed from any device with internet.
Using a VPN or a TOR is now allowed given that your account achieves certain criteria similar to a captcha free account requirements.
🛑WARNING: FREEBITCO.IN wipes inactive accounts after a certain period! If you lose interest, withdraw your BTC!
📝NOTE: iOS devices (iPad, iPhone) are restrictive. The only way to access is via website, as BitBot isn't available.📝
FREEBITCO.IN is what's called a "faucet", a site that gives a small steady stream of crypto which FREEBITCO.IN does through hourly rolls and interest accrual.
FREEBITCO.IN also hosts other means to win or earn crypto, you can gamble with Multiplier, or bet on world evens and crypto prices.
After your account reaches 30k Satoshi, you begin to collect interest. The site also offers lifetime referral commissions, explained later in this guide.
All you need to start is an email. You can add more verification options for security later on. I would highly suggest it. Use a junk email though.
2FA and MFA are strongly suggested. A password should be 15 characters long. I suggest Google Authenticator for your 2FA needs.
I know you can definitely access this site from Brave Browser with add blockers enabled. I'm sure it will work with others. Even without an ad blockers, they only advertise their site gambling and games, no 3rd party adds that I've seen. It's not too invasive or spammy either.

2️⃣POST INTENTIONS2️⃣
This post is both an advertising platform I use, and a guide I've made to help those interested to automate and optimize earnings.
For those of a cautious mindset, I've uploaded all of FREEBITCO.IN's information on interest accrual, security, and proof of mining on Imgur, in case you're worried about visiting the site.

3️⃣MY EARNINGS3️⃣
So at this point, with hourly claims and daily interest, I'm bringing in roughly 8978 Satoshi (or .70$ USD with BTC at 7804$ USD) daily at full optimization on one account, and two other self referred accounts without lifting a finger. This is before the fact that a hourly roll (claim) can reward up to a max of 200$ USD worth of BTC (percentages in section 5️⃣).
They also have a weekly lotto (tickets awarded with every roll and referral roll) with the last 1st place winner receiving .32769156 BTC (2587$ USD at current bitcoin price).
This is also not including my current commissions on accounts not owned by me. In this post I will describe some of my strategies I've incorporated, and some insight into how this website works.
To offload or withdraw bitcoin, you're going to need what is called a "wallet". I personally use Coinbase (available on mobile or desktop) as you can sell it through here as well and easily move money to Paypal or a bank.

If you are already on FREEBITCO.IN, do you have someone who referred you? Do they share commissions? If not, why not make a new account and join me, where you'll get a return on everything you earn.
As you can see, large affiliate groups don't share anything, hoarding hundreds of thousands worth of BTC earned off their referrals
I share 50% of my commissions. I get 50% of your roll rewards, 25% of your interest, and 0.4% of your wagers. All of this is paid out by FREEBITCO.IN as a commission, so it's not pulled from your rewards or held BTC.
So the more you're active, the more you'll receive from me weekly (being active is doing anything that I get commissions from). IMPORTANT: Your (and all referrals) shares are based on activity, so if you are inactive for the week, you get a lower % for that week. If you're the most active of my referrals you get a higher percentage of what I share. This is to incentivize being active and to stop people from getting a cut without doing anything.
If you have FREEBITCO.IN automated, you don't have to worry about this. However, having a larger bankroll to earn interest, or playing Multiply BTC (I do not suggest playing unless doing so to meet auto roll requirements) will increase can your activity further.
Commission Structure
Here is some proof, I've actually shared about 2/3 of all commissions
Commissions update 12 January 2020
Here is a proof of Payment section per individual
📝NOTE: I've noticed when I was creating the images of commission sharing that the "RECENT" blocks are showing zero. If you look at totals from the first image, you can tell I'm actively sharing with all of my referrals.📝

5️⃣SOME CLAIM STATS5️⃣
You can earn AT LEAST .00000552 BTC (.048$) daily when automated (or claiming every hour on the hour) before bonuses (like using reward points to increase rewards 1000%). After some testing, it seems that this amount will always be about .048$ worth of BTC, base claim rewards no bonus active.
After .00030000 BTC, you accrue compounding interest at a rate of 4.08% APR, paid daily. As soon as your daily interest is accredited, it too starts earning interest. The daily interest rate comes out to ~0.011% of your total held BTC.
FREEBITCO.IN gives you a roll once every hour, free
📝NOTE: Roll rewards fluctuate inversely with BTC price. BTC goes down, roll rewards go up, vice versa. The BTC rewards USD value will be extremely close to the values represented below.📝
Current rewards and probability with every hourly roll.
(.002$) -> 98.85%
(.02$) -> 1.00%
(.20$) -> .08%
(2.00$) -> .04%
(20$) -> .02%
(200$) -> .01%

6️⃣MULTIPLY BTC STRATS AND INFO6️⃣
🛑!WARNING!, NO STRATEGY IS 100%, THE MULTIPLIER GAME IS GAMBLING, YOU CAN STILL LOSE YOUR WHOLE BALANCE IF YOU PUSH YOUR LUCK.🛑
UPDATE: I decided to do some research after some odd outcomes when extensively testing some of my Multiplier strats. Turns out FREEBITCO.IN does indeed have a house advantage that isn't too transparent. Longer sessions are almost always going to come out negative. If you still plan on playing, do short sessions, once daily max, with lower amounts.
There are a couple methods to play the Multiplier with a reduced risk (but still a risk) here as well. I would suggest small play sessions.
STRAT #1
My preferred settings for AUTOROLL on MULTIPLY that I've had the best success rate with to date. (preferably with .00005000 in ACCT for best results)
BET: Minimum
ODDS: 3
ROLLS: (doesn't matter, 100)
BET ON: alternate
STOP BETTING PROFIT: .00000050, important as the bets will get exponentially higher with every loss. Win in small increments.
STOP BETTING LOSS: Set a loss limit if you want, I have mine set to .00001 and haven't reached it
ON WIN: select increase bet 0%
ON LOSS: select increase bet 65%
RANDOMIZE CLIENT SEED: yes
DO NOT REFRESH: yes
Here is a pic of the settings
Anything else doesn't matter. Make sure the boxes are checked for the above options.
With this strat, I've won positive on one account, about .000077 BTC, and I've only played 5 or 6 times, at less than 2-3 minutes of play time a session.
STRAT #2
Good for accounts with a low balance. I've had a surprising amount of luck with this method, enough so that I thought I'd post it here with an update. This could work well for accounts with less than 1k Satoshi, as a losing streak wouldn't be a huge loss. For this strat, you should have at least 189 Satoshi in your account.
BET: Minimum amount
ODDS/WIN CHANCE: 189 or %0.5
ROLLS: 189 (remains the same no matter if you bet more)
BET ON: High or Low, but not Alternate.
STOP BETTING ON PROFIT: Minimum amount, once again, you want continuous small wins
UPDATE: Conducting more tests for viability
I played these settings 10 times, I came out positive 8/10 times. In the end I was positive 433 Satoshi total with selecting "hi".
On selecting "low" I went positive 5/10 losing 525 Satoshi.
On selecting "hi" and betting 10 Satoshi, I went positive 3/10 times losing 9708 Satoshi.
On selecting "high" and betting 100 Satoshi, I never went positive, 0/10. Losing 189000 Satoshi (~15$ USD).
There does seem to be a pattern of losing more when betting more. Like anything gambling, there's probably a house advantage that's not too transparent.
Win small lose small.
Pic of these settings
STRAT #3
Another strategy I've tried is betting most of my balance once occasionally with a 94.06% chance of winning. This is, eh, alright to risk OCCASIONALLY, but a loss would set you back more than you ever made using this strategy, which happened to me, I lost about 40 USD worth of BTC after making maybe 5 USD.
THIS METHOD IS GREAT FOR MEETING NON-CAPTCHA ACCOUNT REQUIREMENTS!
Playing this in auto roll, out of 20 rolls I'd always lose at least once, putting me into the negative. Even with 10 rolls, I'd more often then not lose at least once.
Pic of these settings
There are other strats out there, such as the "Martingale", which is essentially doubling the bet amount every loss, then resetting your bet to minimum after a win to in theory "win back what you lost". At 47.5% odds of winning, I've had loss streaks that would drain my account.
My summary for Multiply, use sparingly. Don't use it as your primary means of earning. Use once or twice daily, limit play sessions to 5 minutes max.
⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹
7️⃣AUTOMATION7️⃣
📝NOTE: FREEBITCO.IN captcha requirements seem to be tiered, with requirements for Captcha free upscaling when you BTC holding passes a certain threshold.
I'm currently testing, as is another team member (Shout out to u/SrExtreme69) , what exactly these thresholds, if holding at these thresholds increases the length of Captcha free rolls, and at what amount does FREEBITCO.IN no longer require these to be met.📝
📝NOTE: To start automating, remember to verify email and setup 2FA or the Captcha will still appear even if your account meets Captcha free requirements. Check the site occasionally as Captcha free roll requirements can change. After certain held BTC amount you don't need to renew your requirements. I haven't had to achieve new requirements in over a month.📝
📝NOTE: You may need to manually roll for a bit until the the ability to achieve a Captcha free account becomes available. It doesn't show at first.📝
📝NOTE: It's very difficult, if not impossible to automate on iOS devices.
First of all, getting to this point can be a grind, but once achieved you'll have a steady flow of BTC with options to increase earnings through rewards claims using RP. I would suggest going to your PROFILE tab on FREEBITCO.IN and disabling lottery to increase RP production when starting out. Using other apps or resources to supplement income is a good idea as well.
On the FREE BTC page, there is a blue text hyperlink with requirements that need to be met to make your account captcha free, thus allowing you to enable autoroll on extensions or apps. It has multiple ways to achieve this and they can change, so if your autoroll has stopped, check to see if these requirements have changed.
Here are the requirements. (Amounts vary)
It seems only two of these requirements need to be met.
The less risky and easiest method is to buy lottery tickets and bet with jackpots on. Even better is depositing bitcoin if you have that amount.
The POSSIBLY least expensive method is to bet both regularly and with Jackpots enabled on MULTIPLY (for higher amounts required, IMO Multiplier strat #3 works best)
⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹
8️⃣OPTIMIZATION AND USE OF FREEBITCO.IN8️⃣
For computers
I would suggest using Firefox, as you can add functions and tools to your bar up top. One of the being a "auto roll" for FREEBITCO.IN, still requires a "captcha free" account. Turn it on and let go, check it occasionally to make sure its still going.
Autoroll firefox add-on link
My link again for ease of access
Not my preferred method, but good for a second account, as using a computer means devoting more attention to FREEBITCO.IN in an inconvenient manner if you are just starting out. After Captcha has been removed, this becomes more hands free, but not as profitable as using bitbot, as you can't autoclaim RP rewards.
I haven't tried many methods besides using Firefox addons, as I'm wary of sources or intent when it comes to 3rd party scripts or programs. If I find any trustworthy scripts or programs, I will update here.
For Mobile
🛑BITBOT WARNING, IF YOU USE BITBOT TO ACCESS FREEBITCO.IN BEFORE USING MY REFERRAL, YOU WILL BE REFERRED THROUGH BITBOT, AND THEY DON'T SHARE COMMISSIONS AS FAR AS I CAN TELL🛑 My Link again
📝NOTE: iOS devices (iPhone, iPad) do not have access to BitBot, nor do they allow extensions/add-ons on their browsers. I have not personally found a way around this. You may still access the site and manually roll.📝
I use BitBot. This is the best place to start from IMO. You can set it to notify you of rolls and gives direct access to the site from the app (you can also access the site from any device with internet). Once your account is "captcha free" you can set it to auto roll AND automatically claim rewards every 24 hours (RP increase, BTC increase, Lottery ticket Increase).
📝NOTE: Bitbot allows auto roll from the app for accounts over 500 RP. This isn't permanent, as it uses your RP. You'll need to log onto the website through a browser to achieve captch free account requirements, which Bitbot does recognize, which allow completely free rolls.📝
📝NOTE: Accessing FREEBITCO.IN through BitBot doesn't allow access to the Hi-Lo or betting games.📝
⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹
9️⃣STRATS TO INCREASE EARNINGS9️⃣
Bitbot optimization
I started manual claims by setting roll notifications to "ON" for a while until I supplemented my BTC in FREEBITCO.IN with what I was collecting from my miner and CryptoTab. Once I was able to AUTOMATE and I had enough RP to claim the RP BONUS, I set it to do that automatically every 24 hours as this nets more RP than you spend (EG, 100 RP roll bonus costs 1200 RP, but can net 2400 RP if claimed every hour). Eventually you accrue enough RP to claim the %1000 BTC bonus, probably at a rate of once or twice a week.
My current BitBot settings now that its auto claiming, I have the 24 hour auto bonus claiming 100 RP roll bonus and 100% claim bonus, spending a total of 1520 RP, but I'm making 2400 RP with the RP bonus, leaving me 780 RP in the positive each day. Every now and then I'll stop the auto bonus claim so I can buy the 1000% claim bonus (3200 RP). So on a normal day I'll make about 1344 Satoshi. Bitbot auto bonus settings
Once your accrue more referrals, or save enough RP, it's possible to claim the 1000% BTC roll bonus multiple days in a row. This is just about as optimal as you can get for auto rolling.
Self Referrals
If you have two devices (phone and computer preferably) you can make two accounts as long as one uses a different wifi or internet connection, as the roll rewards tracks IP addresses for roll counts. So if you have 2 devices on the same network, it sudo links accounts, so if you roll on one, it restarts the timer on the other. This allows you to collect referral rewards from yourself. Effectively adding 25% of interest and 50% roll rewards.
I currently have a phone autorolling on BitBot with a computer autorolling on Firefox with a tool to roll automatically as long as the page remains open. My computer account is referred from my mobile account, and is currently bringing in an extra .000015+ BTC weekly (currently, total will be this Sunday and I will update).
I've also made another account on my partners phone, linked it with bitbot and got it auto-rolling. Once bitbot is going, its non-invasive and you can silence notifications, it also uses minimal data.
Supplementing with CryptoTab
I'll use CryptoTab on my computer 24/7 to earn BTC from that while I have FREEBITCO.IN running. I also have it running on my phone at night when I sleep and on an iPad I have that I don't use much, its server mining, so no worries about battery on mobile devices. On computers it does actually use your processing power. You can directly deposit into you FREEBITCO.IN accounts.
CryptoTab Link
I've used it for two weeks and have earned a total of .000454 BTC (3.60$ USD). Not huge, but enough to start collecting interest on FREEBITCO.IN and to get the capthca free account requirements.
Supplementing with Cointiply
🛑WARNING: Cointiply's main currency is the constant, weighted against the dollar (10,000 coin/1USD). This means your actually BTC holdings will fluctuate with BTC's price.
For this reason, it's my strong opinion that DON'T HODL in Cointiply as you're not holding actual BTC.🛑
Cointiply is a great site to earn decent amounts of COIN which translate to SAT's. Earn coin, withdraw to FREEBITCO.IN (as you actually hold BTC in cointiply).
I also use an ASIC miner (Antminer s9i, DIY liquid cooled and overclocked with BixBit firmware), and whatever I earn I'll put that into FREEBITCO.IN to collect interest. If you want, I may be willing to do a rental.
⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹
1️⃣0️⃣ADVERTISING YOUR LINK1️⃣0️⃣
📝NOTE: Since this faucet has been around a while, many people privy to sites such as this are already signed up. So getting referrals can be a slog. My tips for your ads is be genuine and don't hard sell or post "too good to be true" sensational ads.📝
COINTIPLY
This is another faucet. Its structure is a bit different from FREEBITCO.IN, as you complete offers to earn coin. Within this site (also an app) users can earn coins by doing PTC ads (and other offers), this is a good method to get exposure as you can advertise as well. Using this method my traffic for last week as about 800 people.
13000 coins buys about 1000 "clicks" on your ads. They also have options to advertise to people based on location (these options will increase or decrease cost). After your first ad, you usually get a 10% off coupon good for 7 days as well.
You can earn this amount within a day doing surveys on Theorem. I've done surveys before, and this has to be one of the best surveys sights I've ever done. Very rarely do I get kicked out mid survey, and if I do, I still get partial pay.
I will also use "Hideout" on my computer and leave it running. It has to be the open tab on your browser, with the browser open, not minimized. Let it go and check it occasionally as it has a timeout at roughly 2-3 hrs idle. As of now this is the best passive method of earning on Cointiply.
PI NETWORK
Pi Network, an ICO (Initial coin offering) based on trust and social media is another good medium for advertising. I will usually see 15-20 people click on my link with 2-4 ads posted per day.
Just go to "chat", select "random" and post an ad in the chat channel. No charge.
My tip, keep your ads short to medium in length, don't spam.
XYO NETWORK/COIN APP
This is another crypto earned through "geo-mining". On the "coin" app you can do a "geodrop" where you can leave a note. Just click on the box with a parachute icon, select "any" on the "Tile" selection. Leave your ad in the "note" section.
It costs 10 "COIN" at the very least to do a "geodrop". This method may not be worth it if you aren't already involved in the program. To earn a substantial amount of coin, you'll need a subscription or a "sentinel". Sentinels can actually be purchased for under 20$ nowadays (depending on site) and is the best option to earn. Without these you'll only make approx .05-.18 coin every 30 seconds if you're actively moving.
My tips if you plan on advertising on this platform, once again keep it short, and only advertise around 7-9am and 4-6pm, as this will be peak mining hours with people driving to and from work.

Weekly Update: First ParJar Pilot Class, Constellation partners with Chainlink, $BAT on 2gether, Pynk on BlockMAG... – 11 Oct - 17 Oct'19

Weekly Update: First ParJar Pilot Class, Constellation partners with Chainlink, $BAT on 2gether, Pynk on BlockMAG... – 11 Oct - 17 Oct'19
Hi everyone! Here’s your week at Parachute + partners (11 Oct - 17 Oct'19):

The first ParJar Pilot Class is officially off to a roaring start with 5 amazing projects and their communities. Here’s to a great future. This was the perfect occasion to announce a ParJar Battle Royale for our ParJar Pilot partners. Blood will be spilled next week. Pow! ParJar now has almost 20k active users. It works in 400+ communities and has seen 400k+ transactions. Say what! Par4Par lottery entered stage 5 this week. The stakes are even higher. 250k $PAR in prizes. Dang! Reflecting on Vitalik Buterin’s observation, Cap says: “...we’ve done things in reverse here at Parachute - we grew an amazing community around exploring ideas and built our tech to meet what they needed”. What are your thoughts on buying houses for USD 1 each in an Italian town for building the Parachute village? Cap’s recommendation. Haha.
Andy’s Advent calendar. Each window is a 16.9 oz can of beer. Sweet!
We saw Tiproom become the 17th most active group on Telegram a few weeks back. Well, hold on to your pants because it is now the 12th most active group. Whoa! A big reason for the group’s constant buzz are the amazing trivias hosted by the TTR crew. This week was no different. Doc Victor’s Sunday medical trivia had 8 Qs, 3k $PAR each. This was a quiz with a twist. In Doc’s words: "..beware, in each question they will have to diagnose a case based on symptoms and signs that I will give them". Noice! Charlotte’s Tuesday Trivia had 10 questions with a 25k $PAR prize pool. Another trivia by Victor (not the Doc) had another 10 Q’s, 2500 $PAR each. Listened to the TTR theme yet? DJ Jose in da house with a rocking theme. Wicked! Congratulations to Mario for winning the pet contest in TTR. Sebastian made a compilation video of all the entries. Awww!
Let’s see if Cap’s guerrilla marketing at Burger Joint in NYC gets us a new Parachuter
Victor’s Friday trivia at aXpire was the usual 10 Q, 100 $AXPR per Q affair. And like always, super duper fun! If you missed news from Week 41 at aXpireverse, Joakim’s got your back. Check out his video to catch up. CEO Gary Markham travelled to India this week to prepare for the Bilr release. Click here to track the latest 20k $AXPR burn. Plus, a featured article by Hosting Advice was pretty cool. 2gether added Basic Attention Token ($BAT) support to the app this week. Let the $BAT spending begin! Use the invite code: paywithbat to get 100 $2GT free when you sign up for the app. Know of a startup that’s going to Malta Blockchain Summit? Let the XIO crew know since the team will be attending along with Uptrennd. Benjamin’s tutorial video on market cycles with the BOMB token as case study was riveting and full of useful info. This week’s Dash-walk-the-talk discussion revolved around getting unstuck as an entrepreneur. After taking inputs from the community 2 weeks back, the BOMB Board finalised on the team and way forward to manage the BOMB Instagram. For the latest update on the Birdchain app, click here. Congratulations to Bounty0x for crossing 2.5x of its funding goal on Republic with more than 2 months to go. Voyager is offering a 5% annual interest on ETHOS tokens held on their platform. Read more about it here. The news was also covered by SludgeFeed. Wendy O shared her usability experience of Voyager as well.
Bitcoin ATM in Alexis’ neighbourhood. Cool!
The McAfeeDex launched last week is off to a tremendous start. Bitcoin Cash’s Roger Ver spoke briefly on it in a news roundup video. 6 portals are live already. If you’re still wondering how to list your token on the Dex, here’s a simple guide from the man himself. Binance Chain support coming soon! SwitchDex is now trackable on DappRadar and State of the DApps. The team has set up a dedicated TG group for folks wanting to BUIDL on SwitchDex. Also, Callisto Network is slated to do a security audit of the McAfeeDex contracts. Great stuff! Peeps who missed the Fantom AMA with G.Crypto from 2 weeks back, can catch up from the transcript released this week. The latest technical update is detailed and covers all major changes in code. Uptrennd started a new video intro contest for a 2500 $1UP prize pool. Woot! Full transcript of Jeff’s interview with OmiseGo CTO Kasima from few weeks back was released this week. $1UP can now be spent in tons of retail chains thanks to a newly forged partnership with MobiePay. Last week we saw Jarau buy a laptop with his Uptrennd earnings. This week we learnt about Zubair buying a mobile phone with his $1UP earnings. Neat! The latest biweekly Dev update and weekly District update from Ditrict0x covers news such as Ethlance redesign, Meme factory NSFW filter etc.
Uptrennd continues to breach new heights on Alexa rankings every week

OST has set up a community slack to coordinate all Pepo related feedback received for the Pepo app. So join in if you want to help out! Did you know that Pepo is home to some of the most influential people in crypto? This week, we heard from Ethereum and Coinbase investor Bobby Goodlatte. The app crossed 20k P2P transactions and is now live in both app stores. The first such with micro-transactions, in-app purchases and cash-out options for crypto. Few weeks back, the Sentivate community chose to burn tokens (vs a raffle). This week, they voted on how many to burn. The $SNTVT crew sat down for a live Q&A with Bit Shaman this week. The team also wrote about possible future use-cases of the Universal Web with short story threads. Cryptoreview.xyz’s review of the project also came out this week. Constellation announced that it is joining Chainlink as a new node operator in order to stream enterprise data to Chainlink’s smart contracts. Click here for the PR release. The technical overview paper gets into details of what the partnership means for both companies. Bags Token hosted an AMA this week in their Telegram group. Hope you had an opportunity to get your doubts cleared. Community member Con built a $BAGS-centric image/gif board called bagsbook. Check it out! In a bit of a sobering news, Scroll (XD Token) ceased business operations this week.
Constellation will act as an oracle for Chainlink by streaming verified data to the network
Pynk was featured in the latest edition of the BlockMAG published by the Malta Blockchain Summit. COO Rupert Barksfield was invited by NatWest to speak on how to get traction for tech projects. Rupert’s interview by Ayo News where he explains how AI and crowd wisdom works in tandem at Pynk came out as well.

(Updated) [Staking] Reddcoin Core client GUI wallet on a Raspberry Pi Model 3B

Intro

This thread is an update to my first Reddcoin staking tutorial that was written 7 months ago.
 
The reason for the update
My Reddcoin Core software crashed and became unusable. My Raspberry Pi 3B would lag and freeze, I couldn't stake anymore.
 
Instead of just redoing everything the same way, I wanted to see if I could improve on 3 points:
 
The updates
 
If you would like to tip me
Writing a tutorial like this takes time and effort; tips are appreciated. My Reddcoin address: RqvdnNX5MTam855Y2Vudv7yVgtXdcYaQAW.
     

Overview

 

Steps

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
     

Video

https://www.youtube.com/watch?v=Snr5e8bzftI
This video shows how long it takes to start Reddcoin Core.   TL;DR:
     

Extra

Backup
Backup your wallet to prevent losing the RDDs in your wallet! There are two methods to backup, do both. Make new backups if you create a new receiving address!
 
 
   
Boot with only 1 USB drive plugged in:
Make sure only the USB drive (with the swap partition and data partition) is plugged in when you boot up your Raspberry Pi. This to make sure the swap partition (/dev/sda1) is recognized correctly.   If you boot up with multiple USB drives, Lubuntu might see the USB drive with the swap partition as the second drive (instead of the first drive), and ignore the 2 GB swap partition. If this happens, starting Reddcoin can render the Raspberry Pi unresponsive.
   
Connection issues If you have issues syncing the blockchain because you have 0 network connections, please follow the instructions in this thread.
   
Start Reddcoin Core easier
Run a shell script (.sh file), so you can start Reddcoin just by double clicking on an icon on your Desktop.
   
Minimization options
Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
   
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
 
   
Chromium as browser: The updates break Firefox, the browser crashes when you try to run it. Install another browser, Chromium, to solve this issue.
   
Updates / Upgrades
If Software Updater shows up and tells you that there is updated software available, do not install the updates using Software Updater. Use LXTerminal to update Lubuntu.

All About Zcoin

All About Zcoin

https://preview.redd.it/hixbz9f3lxm31.jpg?width=1200&format=pjpg&auto=webp&s=43896de84a3693d840c84057c0314af71718f0a3
What is Zcoin?
Zcoin, also referred to as XZC or Zerocoin, is an open source decentralized cryptocurrency that provides privacy and anonymity for its users when making transactions.
To achieve its privacy and anonymity, Zcoin uses zero-knowledge proofs via the Zerocoin protocol, which is at this moment in time one of the most cited cryptography papers.
According to Wikipedia, in cryptography, a zero-knowledge proof or zero-knowledge protocol is a method in which one party proves to another party (the verifier) that a given statement is actually true.
In other words, in a transaction with Bitcoin or Ethereum or something similar, your transaction history is always linked to your coins by default, leaving you vulnerable. All it takes is one link to your personal information or IP to find out the origin of the coins.
However, when you trade with Zcoin’s Zercoin feature, your transaction history is not linked to the actual coins. Only the receiver and sender know that the funds have actually been exchanged.

How Does Zcoin Work?

Zcoin works on the Zerocoin protocol by enforcing Zero-knowledge proofs. Here are the components of Zcoin to explain how it works.
Mint: When sending a private transaction with Zcoin, all you need to do is select the number of coins you want to mint. Post that your normal Zcoin balance would reduce automatically and you will be credited with new coins and no transaction history. In essence, your old coins are burned cryptographically, which prevents anyone else from using them again and being directed to your transaction history. You get credited with new coins with no history, while the total supply is maintained.
For now, you can only mint in denominations of 1, 10, 25, 50 and 100. If you choose ‘100’ coins to be minted, for instance, you will instantly be credited with 100 new Zcoins with no history attached to them.
  • Spend: When you want to make a private transaction, you will be required to use these ‘100’ newly minted coins. From this pool of funds, you can now send any amount in any denomination to anyone anonymously because no history is attached to it.
  • Repeat: You can ‘mint’ and ‘send’ Zcoins any number of times at anytime with your privacy intact.

Zcoin’s Vision

Zcoin seeks to improve things that Bitcoin hasn’t been able to so far, some of which include fungibility, privacy and miner’s centralization.
Users of Zcoin can enjoy full fungibility and privacy along with demolishing miner’s centralization by implementing a better proof of work algorithm called MTP.
Total Zcoin supply
Only 21 million units of Zcoin will ever be produced. Currently, there are about 3.4 million units in circulation, with the rest yet to be mined.
But the total supply has increased by 388450 XZC units after a Zcoin code bug, which the team refused to roll back due to economic reasons, which is why the total supply stands at approximately 21.4 million.
Every 10 minutes, a Zcoin block is mined and 50 coins are generated, making 72,000 Zcoins per day.
Market cap of Zcoin
According to CoinMarketCap, the total circulating supply of Zcoin is 5,757,841 XZC and the current unit price is $9.6. That makes the market cap approximately $55 million*.*

Zcash:
Zcash is a decentralized and open-source peer-to-peer cryptocurrency that provides strong privacy protections. It was created as a fork of Bitcoin and, like bitcoin, it also has a hard limit of 21 million coins. Unlike bitcoin, however, Zcash offers total privacy for its users maintaining the absolute anonymity behind each transaction along with the parties and the amounts involved in it.
PIVX:
PIVX, which stands for Private Instant Verified Transaction, is an open-source, decentralized form of digital online money that uses blockchain technology. This makes it easy to transfer all around the world in an instant with low transaction fees with market leading security & privacy. PIVX focuses on privacy, security, anonymity, and instant transactions.
Monero:
Monero is a fast, private, secure and untraceable digital currency system that uses a special kind of cryptography to keep all its transactions 100% unlinkable and untraceable. With Monero, you are your own bank. You can spend safely, knowing that others cannot see your balances or track your activity.
Some Zcoin misconceptions
There are some misconceptions regarding Zcoin:
  • Some believe that, since Zcoin has a trusted setup that allows indefinite minting of coins, it is not safe. This is untrue. Of course, to start with they had to use a trusted setup because they have an auditable total coin supply that prevents any form of cheating. This downside however, is being taken care of by removing this trusted setup in the near future and when that happens, Zcoin will be one of the serious coins to count on for privacy.
  • Zcoin has been considered as Zcash’s fork but that is also not true because Zcash is based on the Zerocash protocol whereas Zcoin was started from scratch by applying Zerocoin tech.
Now that some of the Zcoin’s misconceptions have been cleared, here’s a look into its future.

Zcoin’s Future & Roadmap

Zcoin’s future is quite promising and worth watching based on these interesting milestones on their roadmap:
  • Zcoin is the first coin to implement MTP proof of work, which makes it possible for general masses to mine Zcoin with GPUs and CPUs. MTP doesn’t allow costly ASIC-like miners to mine XZC coins.
  • Zcoin is also implementing Znodes to make their cryptocurrency more decentralized and anonymous. These Znodes will be like masternodes and facilitate anonymous transactions as making an anonymous transaction single-handedly is quite computational.
  • Znodes will be incentivized by reducing some portion of the founder’s reward. Also, the surplus funds that get generated from the founder’s reward reduction would be used for hiring new developers and increased marketing efforts.
  • Another agenda on their roadmap is to bring inbuilt Tor or some IP obfuscation mechanism that will make it completely anonymous.
  • Apart from these, some innovative and exciting things like sigma protocol, decentralized anonymous voting and Zcoin Labs are on their roadmap, making this project worth checking out.
  • Last but not least, its recent price is a good indicator of its healthy market sentiment and shows that there are people who understand this project’s worth. Just to put things into perspective – a unit of Zcoin was priced $2 in March 2017 and now it is $37*.*

Zcoin Team & Progress

Zerocoin is a cryptocurrency proposed by professor Matthew D. Green, a professor of Johns Hopkins University, and graduate students Ian Miers and Christina Garman. It was proposed as an extension to the Bitcoin protocol that would add true cryptographic anonymity to Bitcoin transactions.
Zerocoin was first implemented into a fully functional cryptocurrency and released to the public by Poramin Insom, the lead developer, as Zcoin in September 2016.
Some of the notable dev members of the team are listed below.
Poramin Insom
Founder and Core Developer
Poramin Insom created what was the world's 4th most valuable cryptocurrency in February 2014. He is also the world's first person to implement stealth addresses in QT-Wallets, improving cryptocurrency anonymity. He earned a master’s degree in Information Security from Johns Hopkins University, where he wrote a paper on a proposed practical implementation of the Zerocoin protocol.
Alexander N.
Developer
Alexander N. aka Aizensou is a full-stack developer who has experience in many programming languages (C++, C#, Python, Perl, Java etc.) and has been involved in the cryptocurrency space since 2013. He has a broad development portfolio from low level APIs in Python and C++ to Android native applications in Java. In addition to his involvement in cryptocurrencies, Alexander was doing his P.h.D. in machine learning at a German university from 2012 to 2016.
Saran Siriphantnon
Developer
Saran Siriphantnon is the CTO of Satang.co/Satoshift, a fintech company focusing on creating an open financial system for Southeast Asia. He served as President of the Computer System Administrator Group at King Mongkut's Institute of Technology Ladkrabang.
Tadhg Riordan
Solidity Developer
Tadhg Riordan is a 24 year old Software Developer from Wexford, Ireland. He recently completed his MSc from Trinity College Dublin, where he worked with Blockchain privacy mechanisms, focusing particularly on Zero-Knowledge Proofs and the Ethereum platform. He is a strong advocate for the adoption of cryptocurrency and for complete financial privacy.
Apart from these, their team comprises of other developers, community managers, support personnel and advisors who maintain the required balance.

Advisors:

Aram Jivanyan (Cryptography Advisor): Co-Founder at Skycryptor & KMSchai
Torphop Korgtadam (It Security Consultant): Senior Vice President, Head Of Internal Audit Strategy, Innovation and Decision Science at United Overseas Bank Limited
Alexander N. aka Aizensou (Advisor)

Unique/Key Features Against Its Competitors:

  • Anonymous transactions. The project establishes a notably higher level of anonymity and seeks to bypass current analysis techniques which governments use to reveal the identity of users.
  • Not subject to transaction graph analysis. Zcoin has an anonymity set that encompasses all minted coins in a particular RSA accumulator that can scale to many thousands.
  • Innovative process. Tokens are burned cryptographically and replaced with new coins without a transaction history. This actively prevents anyone else from using the tokens again and stops the public from being directed to a user's transaction history.
  • Transparency focused. Zcoin's main advantage is its auditable money supply.

Beginners guide to Syscoin (SYS) and why you should be investing in this cryptocurrency in 2018

What is Syscoin?

Some have described Syscoin (SYS) as the Shopify, Amazon and Ebay of the blockchain world. Syscoin is a revolutionary cryptocurrency that offers near zero cost financial transactions, incredible speed and provides businesses the infrastructure to trade goods, assets, digital certificates and data securely. Syscoin isn’t just about money and trading, it has the ability to attract various business types thanks to its native set of features geared towards business on the blockchain. From eBay traders and High Street shops to Medical applications, Insurance and Gaming, Syscoin’s decentralized network benefits everyone!
Syscoin is developed by Blockchain Foundry (BF). BF provides blockchain technology based services, projects and products for a wide variety of use cases with the stated aim of disrupting markets by leveraging the potential of blockchain technology. Syscoin is mainly known to be the first cryptocurrency to offer a fully decentralized marketplace based on blockchain. What is lesser known is that this is only a part of what Syscoin offers.
With the introduction of Masternodes in February or March 2018 SYS will be transformed from just a ’marketplace coin’ to a completely ‘utilitarian coin’. The Masternode infrastructure allows the addition of decentralized databases and file storage, increased transaction speed to surpass POS/Visa/Mastercard capabilities, true Turing complete smart contract capabilities for unlimited business logic, sidechains, application layers and an identity layer. This will all be accessible through an API, rather than a new language, enabling nearly any developer to create any blockchain application they can conceive. This will usher in the next generation of blockchain applications - made for new or existing businesses - by conveniently offering everything available from the blockchain space today.

SYS Origin

The blockchain as conceptualized by Satoshi Nakamoto back in 2008 envisioned a peer-to-peer electronic cash network that would prevent double-spending. A year later, the blockchain became an integral part of bitcoin, serving as the latter's public ledger of transactions. Although Nakamoto's reference client mentioned a decentralized marketplace service, the subsequent implementation did not incorporate this due to a lack of resources.
Syscoin was initially described in a 2014 draft whitepaper that envisioned Decentralized Marketplace Creation, Decentralized Smart Contracts and Documents, Decentralized Certificate Issuance and Transfer, and Decentralized Data Storage and Retrieval, as among the services that it would offer upon its release.
Syscoin aimed to bring Nakamoto's vision of a decentralized marketplace back into the blockchain, among the other commercial-grade services it aims to deliver to clients. Other services that Syscoin plans to provide include secure data storage and transfer, and unique user aliases that link their owners to the services controlled by the alias.
The early Syscoin wallet was superseded by the release of Blockmarket Desktop 1.0 on September 12, 2017, marking the culmination of Syscoin's vision of a fully decentralized marketplace with a desktop GUI based on the blockchain.
The planned release of Blockmarket Web, a fully web-based version, and Blockmarket Professional in 2018 takes that vision one step further, as more advanced seller stores become a reality.

The Team

The Team that NEVER quits! Before the launch of Syscoin (Q3 2014), there was a presale ICO by Moolah (as a partner), which turned out to be detrimental for Syscoin. The project raised around 1,000BTC for development but the Syscoin Team only managed to access 250BTC which were used for price support. Moolah (Ryan Kennedy) absconded with the bulk of the ICO funds and the Syscoin team were left with ~30million Syscoin at a price around 400 satoshi. Even after this tragic event, the devs didn’t quit and continued to work on the project without stopping. The case against Moolah is still on-going. See the article from CoinDesk here: http://www.coindesk.com/uk-court-syscoin-injunction-moolah-750-btc/.
What is this detail telling us about the dev team? While some crypto projects are just scams and bring little to no innovation, they’ve proven that they are in it for the long term - ably demonstrated by the fact that they continued to work despite their funds being stolen. And now that hard work is beginning to pay off with the entire team going full-time for the first time in January 2018 and new developers being hired following VC funding for BF.

What is Blockmarket Desktop?

Building on the World's First Decentralized Marketplace, Blockmarket is the newest generation of Syscoin's Desktop wallet with a complete, state-of-the-art marketplace built-in where you can securely and reliably buy and sell any items you wish. Entire stores can be created directly through the marketplace where you can sell your own products or re-sell others’ products for commission. Use of blockchain technology eliminates middlemen, credit card fees, maintenance fees, downtime and political interference. Persons are literally able to buy or sell anything to anyone, anytime, anywhere on Earth! Blockmarket Desktop was launched on September 12, 2017.

Key Blockmarket Features

• Price Pegging to currencies such as USD, EUR, GBP, CAD, CNY and BTC
• Bitcoin and Zcash as payment options
• Arbitrated Escrow
• Encrypted Messaging
• KYC/AML Compliance
• Images

Name Aliases

Wallet addresses for cryptocurrencies generally consist of a unique string of between 27-34 alphanumeric characters. Such an address isn’t easy to memorize. Although the addresses can be added to an address book within the wallet, Syscoin has taken the user's convenience one step further, allowing you to create a unique Alias for your wallet address, such as a name, title, or characters specific to a username. These can be used to send SYS from home, to a mobile wallet, to work, to friends, to common suppliers or to repeat customers easily, without requiring any memorizing, writing it down, copy & pasting or emailing yourself the address.

Digital Certificates

Using the cryptography of the blockchain persons can issue, authorize, and exchange digital certificates of any kind. With Syscoin anyone can issue provably-unique certificates with text or ASCII content to one or multiple parties on the Syscoin blockchain. These certificates can be authenticated by anyone via Syscoin’s cryptographic proof of work. This allows for the creation and free exchange of any kind of digital asset such as ownership certificates, warranties, receipts, tickets, certifications, diplomas, software licenses and more.

Integrated Exchanges

Integrated Crypto exchanges - Flypme and Changelly will facilitate exchanging 30+ cryptos for SYS, directly within the Blockmarket wallet.

Security Audit Verified

Blockmarket was successfully and independently security audited by Digital Boundary Group and was deemed low risk. Audit Results: [https://medium.com/@BlockchainFoundry/blockmarket-security-audit-results-and-next-steps-f69f94f149bf]

Blockmarket Web – (The Key to Mass Adoption)

BM web will bring SYS’s existing decentralized marketplace and all its features into a web-based version, enabling ease of use with a simple email and password login (grandma friendly) without any need for downloading a wallet or waiting for sync. Blockmarket web will be launched in February 2018.

Key Syscoin Developments

Masternodes

Ability for world-class transactions-per-second performance to scale-out with added nodes (theoretically 100k TPS per 1000 Masternodes, 300k TPS/3k masternodes, etc). In later releases, masternodes will also process smart contracts and facilitate sharded+encrypted offchain file-storage (with onchain anchors), among other touted functionality. They should also result in steadying the price movements - less volatility as holding will be incentivized

Smart Contracts

Scalable Ethereum Virtual Machine: Allows Turing complete smart contracts to be executed following the ethereum protocol at a much faster speed and at a fraction of the ethereum gas price.

Assets & Token Issuance

With its token issuance service, Syscoin allows anyone to create a custom asset token which can then be sent directly to anyone else on the network. This facilitates a variety of use cases including ICO token issuance, supply chain management, reward points, and loyalty programs.

Anonymous Transactions

Anonymous transactions: via mixing/shuffling at user-specified denomination. Afterwards, additional tech will be added in the near future which will further compound the degree of anonymity provided -Add ValueShuffle running on top of the masternode layer and you have the world's most advanced privacy tech in any coin. This brings true money fungibility to Syscoin and the missing link for true economic sovereignty. https://twitter.com/realSidhuJag/status/948588279540035584

Instant Send

Transactions can be sent and received instantly. This represents a similar sending capability as Dash, but is a step beyond- A type of backend node locking will allow an instantly received sum to be sent immediately, without delay, and without network risk of double-spend.

Bitcoin-Qt has been running for over a week and still hasn't synced

I downloaded and started the Bitcoin-Qt wallet over a week ago, and it's still at blocks from 29 weeks ago. The wiki says that it takes about a day... Is this normal?
Thanks.

Update UNO wallets to 0.11.0

UNOBTANIUM WALLET UPDATE. It's time to update your UNO QT wallet to 0.11.0 for bip65 support and misc fixes.
Get a compiled wallet at https://unobtanium.uno or roll your own from https://github.com/unobtanium-official/
This is an important update for enabling BIP65 consensus that will enable checklocktimeverify
BIP65 has been active in Bitcoin for nearly 5 years. The UNO network wants to enable this to enhance exchange safety and enable p2p 'atomic swap' apps. We need a consensus on the UNO network, which we have, but we want EVERYONE using the 0.11.0 wallet for the best network experience.
More info from the Bitcoin implementation of BIP65:
" In late 2015, the BIP65 soft fork[3] redefined the NOP2 opcode as the CheckLockTimeVerify (CLTV) opcode, allowing transaction outputs (rather than whole transactions) to be encumbered by a timelock. When the CLTV opcode is called, it will cause the script to fail unless the nLockTime on the transaction is equal to or greater than the time parameter provided to the CLTV opcode. Since a transaction may only be included in a valid block if its nLockTime is in the past, this ensures the CLTV-based timelock has expired before the transaction may be included in a valid block. "
UPGRADE TO 0.11.0 TODAY!

How will the (literally) growing problem of an enormous blockchain be addressed in the future?

To my knowledge, we need a complete history of the blockchain to be able to assure ourselves that transactions and balances are accurate.
Could 'someone' we trust cryptographically sign and verify a block in the middle of the chain? For instance, Mt. Gox could take block 210,000 and a snapshot of all known balances, and sign it with the private key and certificate they use for the website.
How do bitcoin wallets run on cell phones without a complete copy of the multi-gigabyte blackchain?
I quess my beef is that when I recently installed bitcoin-qt on a new computer, it took me like 2 days to download the history to be able to use my new wallet freely... Is this making any sense?

2nd November Development Update

https://medium.com/@nytmarecrypto/anon-development-update-nov-2nd-2018-79710fe8acde

ANON Development Update- Nov 2nd 2018

In the spirit of continued transparency, the ANON community admin and Development teams have begun regularly cadenced conference calls to stay abreast of development news, address questions and share community feedback. This consistent feedback loop aims to provide an aggregate platform for 2-way communication with the community. Meetings will spotlight current development focus, next tasks in queue, technical updates, Q&A, and community feedback.

Notes / Recap10/26/18 Conference Call

With Bushido Lab taking on additional projects and the project now post fork, what is the current structure / time allocation for ANON? Currently, post fork there are 4 developers dedicated full-time to ANON. Greater group collaboration and input is utilized as needed. The team does have
