The VeriBlock team is excited to announce the launch of Bitcoin Squared (BTCSQ), the world’s first blockchain secured against 51% attacks in an entirely Decentralized, Trustless, Transparent, and Permissionless (“DTTP®”) manner through the VeriBlock® security network.
Bitcoin Squared serves as a reference implementation for any Bitcoin-family blockchain to implement the PoP® (“Proof-of-Proof®”) consensus protocol, introducing a new form of decentralized lightweight mining which reinforces a blockchain’s existing consensus (PoW, PoS, DPoS, PoST, etc.) with the full security of Bitcoin.
Bitcoin Squared Mainnet will launch at 10am ET on December 9th, 2021, at which time the download links for the final Mainnet package will be made available.

QUICKSTART GUIDE: Getting Started

DAEMON:
Windows x64: Here
Linux x64: Here
Source: Github
(Note: compilation of the BTCSQ daemon from source requires compilation of the VeriBlock reusable library, instructions available here: Here)

Technical Specifications
Name: Bitcoin Squared
Symbol: BTCSQ
Security Inheritance Protocol: Proof-of-Proof (PoP) Mining
Block Generation Protocol: Proof-of-Work (PoW) Mining w/ SHA-256D
Block Time: 2 Minutes
Total supply: 21,000,000
PoP/PoW split: 50% PoP and 50% PoW

Emissions
While BTCSQ has the same total quantity of emissions (21M) as Bitcoin, BTCSQ’s emissions curve deviates from Bitcoin’s standard 4-year halving model.
During the incentivized Testnet phase, approximately 439923 BTCSQ were mined, which were reflected in the genesis block of BTCSQ Mainnet. The following schedule dictates the new coin emissions:

FAQ

About VeriBlock
VeriBlock serves as the world's first blockchain which allows every blockchain in the world to inherit the full Proof-of-Work security of Bitcoin in a completely Decentralized, Trustless, Transparent, and Permissionless (or "DTTP") manner. The VeriBlock blockchain is built 100% from scratch, and has been engineered from the ground up to provide the most cost-effective, secure, and easy-to-use way for the world's blockchains to enjoy the unparalleled immutability of Bitcoin itself.

About Proof-of-Proof (PoP)
Proof-of-Proof is a novel consensus protocol invented by VeriBlock, Inc. which allows any blockchain (including sidechains and permissioned ledgers) to inherit the full security of Bitcoin in a truly Decentralized, Trustless, Transparent, and Permissionless (or "DTTP") manner.

It does so by gamifying the publication of data representing a blockchain's present state to Bitcoin (directly or indirectly through VeriBlock’s security network) such that any user can participate and receive compensation for enabling blockchains to inherit Bitcoin's security. If you'd like to dive into the technical details, please check out our whitepaper.

About vBFI
Users of a VeriBlock-PoP-secured altchain can use the VeriBlock Bitcoin Finality Indicator (“vBFI”) to easily determine exactly when a transaction on an altchain network has as much (technically, more) security as a transaction on Bitcoin itself.
As soon as vBFI reports a Bitcoin confirmation value greater than zero for a block on a PoP-secured blockchain, the transactions contained within that block cannot be double-spent without performing a 51% attack on Bitcoin itself. For example, a transaction in an altchain block with 3 Bitcoin confirmations reported by vBFI is as hard (technically, harder) to reverse than a transaction directly on Bitcoin itself with 3 confirmations.

Frequently Asked Questions: FAQ

1. How do I stake? Just leave your wallet on and after 24 hours your coins are eligible to "stake" and mint. We call this "matures". There's a chance every 90 seconds your make crypto, if not, you wait and your chances get better over time. This applies to each individual stack/line in your wallet.
2. Do I have to leave my wallet open? Yes, to make crypto, but if it's not mature, you can turn off your wallet.
3. When do I stake? 24 hours or later
4. How is this related to 808 Coin/sprouts classic etc? The original proof of stake coins like sprouts classic, 808 coin, and tek coin were headed by Thundertoe and Mr.Eggman (both the same person). They openly admitted they don't know how to program, which is why their projects went nowhere and their coins were full of bugs, exploits, and no developer support, causing the coins to go down in price in free fall. We wanted to avoid that as future crypto currency adopters deserve and want a stable coin with good returns that won't "break" on them when bad actors come in and try to disrupt the crypto currency/bitcoin space. This is the future and we intend to bring everyone that wants it to go forward to a bright and happy future.
5. Supply may get out of control after 5-10 years plus? We may consider lowering APR to around 10-60% down the line. We won't have to worry about that until around 20 trillion coins, which will take a LONG time.

Today we are happy to finally announce the launch of  Selacoin.
 
A bit of history on the name SelaCoin  - sela was one of the first coins in history used for trading - and was originally  made purely out of nickel.
The ancient Sela was known across the globe as the only means to pay for commodities and services, and was more secure then other coins due to its exact size and specific weight - making it near impossible to forge.
 The Sela also proved itself immune to nature or time, as it didnt rust or react no weather nor age!!
No matter how hot or wet the enviroment was, Sela could take it - Making it the perfect intercontinental coin early explorers took with them.
Sela Coins are still being found in perfect condition to this day in archaeological sites across the world, proving just how the ancient Sela was a pioneer of its time.
The Sela Coin was one of the main starting points for modern cash systems, and basic trade, that entually changed the world !


How is SelaCoin different then other coins?

1. the fee for any trasaction is constant - it will not go up like some coins do when there are more users -no it is the lowest possible and will remain so .

2. the trsaction time is super fast! apaert from fast trasactions the coin uses latest imporvments to support enviromently friendly mining /staking - we offer one of the best / highest staking amounts compared to others.

3. the SelaCoin is  basicaly bitcoin on steroids - faster trasactions, clean and eay to use ui, very low resource consuption on mining.

Fair Mining!!!
anyone can mine SelaCoins without having to use super computers and yet hard enough to allow only the ones who really want to keep using selacoins - to earn a steady income with pos (proof of stake)
This project will outlive most other cryptocurencies due to the nature and way it was built.
Unlike other coins which claim to Be opensource and community driven, yet charge huge amounts to build on top of them or to use like etherum and bitcoin - we offer anyone intrested to host his own node, block explorer and other solutions complete support and very low fees that will Never Ever go up.
we host a large number of tutorials on how to build your own crypto currency using SelaCoin on our website - https://sela-coin.com/#guides

the coin was premined at less then 1% to allow payment to node upkeepers as well as payment for future bounties.

the current project is maintained by huge team of developers and can be found on our github -
Our mission is simple -  Build A world of cryptocurrencies  will be using SelaCoins.


the current rewards and configurations for mining are as follows :

Pow Mining : 250 SelaCoins Per block
Pow : 150 SelaCoins per year /SelaCoin

To begin mining on windows:
1. download the SelaCoin Wallet to your computer and install it
2. open the selacoin.conf file and paste in the following :


rpcuser=rpc_selacoin
rpcpassword=11a30f911gggytytyyted1cc7252e6c7bb503
rpcallowip=127.0.0.1
rpcport=25521
listen=1
server=1


3. Download cpuminer from https://github.com/pooler/cpuminer/releases/tag/v2.5.0 and extract the zip file.

Create a miner.bat file named miner.bat and paste the following text into miner.bat.

minerd --url=127.0.0.1:25521 --userpass=rpc_selacoin:11a30f9ed1cc7252e6c7bb503
Save the file inside the extracted cpuminer folder.

Open your wallet and keep it open, then execute miner.bat to start mining your first Sela block.


Social bounties and others (limited time only :
