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.
