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) 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.


DTTP
DTTP stands for Decentralized, Trustless, Transparent, and Permissionless; the core attributes which allow Bitcoin to achieve true security. We designed the VeriBlock blockchain and the Proof-of-Proof protocol with strict adherence to the properties which made Bitcoin what it is today, and believe that for any blockchain to truly inherit Bitcoin's security, it must do so in the same manner.


How is VeriBlock Mined?
The VeriBlock blockchain is mined in two different ways: PoW and PoP mining. PoW miners are responsible for creating the blocks, providing the blockchain with intermediate consensus, and providing blockchains inheriting security through VeriBlock with a PoW-powered first line of defense.

PoP miners are responsible for publishing a representation of the current state of the VeriBlock blockchain (and by proxy, all blockchains secured by VeriBlock) to Bitcoin in a fully DTTP manner.


How does VeriBlock Help Blockchains?
The use of Proof-of-Proof through the VeriBlock ecosystem enables any blockchain to inherit the consensus security of Bitcoin in a way which makes consensus attacks (rewriting agreed-upon history to perform attacks like double-spends) far harder to execute. This additional security significantly increases trust, allowing the blockchain's token to be listed on more exchanges, reduce confirmation waiting times for existing exchanges, and participate in fiat markets, due to the drastically reduced risk of consensus-related token theft. Consumers now have more confidence in the blockchain, and the project's developers can focus on creating a rich feature profile rather than inventing and implementing exotic and untested security mechanisms.


How does VeriBlock Help Exchanges and Merchants?
Due to the proliferation of secure blockchains, exchanges and merchants can list coins from more blockchains while generally requiring fewer confirmations, due to their dramatically reduced risk of double-spends.


How does VeriBlock Help Bitcoin?
PoP miners securing the VeriBlock blockchain spend Bitcoin to publish information regarding VeriBlock's present state, thereby increasing buy pressure for the Bitcoin coin while paying Bitcoin miners higher fees. VeriBlock also gives Bitcoin's PoW an eco-friendly image because it's PoW can be reused to secure a limitless number of blockchains.


How Hard is it to Attack a Blockchain Secured by VeriBlock?
Once a given block on a VeriBlock-secured blockchain reaches full security (after a period of time dependent on the aggression of the weighting algorithm employed by the blockchain and the absence of conflicting data, which is seen in real time), reversing consensus on that block would require forking Bitcoin, VeriBlock, and the VeriBlock-secured blockchain simultaneously.


How is VeriBlock Different From Sidechains/Drivechain?
VeriBlock Proof-of-Proof is a complementary technology to sidechains/Drivechain. Provided a sufficient security budget, a sidechain can adopt VeriBlock consensus technology just like any other public blockchain.


Why does VeriBlock Require a Coin?
The VeriBlock blockchain provides an aggregation layer of proof, and its coin provides a means for paying the decentralized VeriBlock PoW and PoP miners in a way controlled completely by the VeriBlock blockchain protocol. As such, the VeriBlock coin serves as a price discovery mechanism that allows the efficient allocation of the scare resource of proof, allowing all blockchains to inherit Bitcoin's PoW security.


What is Required for Proof-of-Proof Mining?
In order to earn VeriBlock testnet coins for PoP mining, you will need a running instance of Bitcoin Testnet (Mainnet VeriBlock will require Mainnet Bitcoin), with an address containing a positive Bitcoin balance. In addition, you will need the free VeriBlock Core Software (NodeCore, the CLI, and the PoP Miner).


What is Required for Proof-of-Work Mining?
In order to earn VeriBlock testnet coins for PoW mining, you will need a computer with unused CPU (or later, GPU) power. In addition, you will need the free VeriBlock Core Software (NodeCore, the CLI, and the PoW Miner).


What is vBlake?
vBlake is the Proof-of-Work hashing algorithm used by the VeriBlock blockchain. It is a tweaked version of BLAKE2b optimized for use as a PoW algorithm.

Everyone please note: this is a testnet launch of VeriBlock; the coins on this network are not meant to be of any value. This is for community testing and feedback, the actual Mainnet VeriBlock network will launch in the future. Smiley

Is this official thread?  What was wrong with the first one, why did you decide you needed a self-moderated thread instead?

They answered this question in the original post.

Cpu/gpu along with the VeriBlock Core Software (NodeCore, the CLI, and the PoW Miner).
Modified blake2b algo (vblake2b)
Testnet ONLY right now, mainnet in the future.

vBlake is the Proof-of-Work hashing algorithm used by the VeriBlock blockchain. It is a tweaked version of BLAKE2b optimized for use as a PoW algorithm.




Not sure what optimizations the vBlake is meant to have, but if it is Asic mineable, then you might want to remove the reference to CPU/GPU in the "What is Required for POW"

Will be watching this ANN

Looks like I see a new coin here with an new type algo. It's on my watchboard now.

Does this coin have something to do with vericoin?

Ok, started reading through the whitepaper, and have some questions. Before I raise them however, given this is a new consensus protocol, it might be best to present a simple example using imaginary coins and people, so that we can all visualize how this works.

Now the questions:

1. If I understand this correctly, every PoP miner would need to transact on the BTC network and embed in their transaction the entire block header of the SI chain, which is being mined by the PoW miners. The two issues I see are a) You are asking PoP miners to pay BTC transaction fees, b) It becomes a race of who does it first so some PoP miners might opt to pay higher fees for their transaction to be mined first and c) The financial incentive would need to be significant for a PoP miner to do so, and cover the BTC fees

2. While you are saying that it would not be practical for someone who forks the BTC chain to take over (re-write) the SI chain, considering that the SI chain would probably be made up of a small amount of hashing power (otherwise, why would you need the hashing power of BTC), and there would already be large pools in play, all they would need to do is also fork the SI chain and provide a solution for the next block faster.

Generally, chapter 6 which deals with #2 above reads very weak, there seems to be some wishful thinking and statements along the lines of "As such, anyone watching the SP blockchain would see what block(s) are at risk for the fork, how much stronger (or weaker) the current chain is compared to the adversarial party’s chain, and could potentially use some means (like balance-based voting) to invalidate the adversarial chain before it is released to the network." don't inspire confidence.

It is ok if you haven't figured everything out yet, be upfront and work with the community. Right now this seems like an overcomplicated solution looking for problem though.

Don't mean to sound critical, and apologies if I have misunderstood anything.
