BitcoinOS Verifies First-Ever ZK Proof on Bitcoin Mainnet

July 25: BitcoinOS, a network of Bitcoin-based rollup chains, has verified the first-ever zero-knowledge (ZK) proof on Bitcoin's mainchain. ZK cryptography is looked to as a key technology for scaling blockchain throughput and usefulness, but the tech is complicated and computationally intense – meaning it was unclear if or when it would make its way to the comparatively bare-bones Bitcoin network. According to the BitcoinOS team, "This is the first permissionless upgrade of the Bitcoin system and the first time Bitcoin has been upgraded without a soft fork." Bitcoin can now be "infinitely upgradable," the team told CoinDesk, "while requiring no changes to the consensus code." BitcoinOS aims to be the "ultimate implementation of a Bitcoin rollup system," eventually serving as a bridge connecting any number of rollups – quick and cheap layer-2 blockchains that are secured by the Bitcoin blockchain and ZK proofs.

July 25 (PROTOCOL VILLAGE EXCLUSIVE): Roxom raised $4.3 million in pre-seed funding to launch the first stock, commodities, and futures exchange denominated in Bitcoin. The company was founded by CEO Borja Martel and CTO Nick Damico. Martel previously founded the LATAM-based crypto exchange Lemon. Roxom's round was led by Kingsway, Draper, and David Marcus, among others. "Bitcoin native financial markets are an important step for holders to access a wide range of financial services natively. Roxom is an important step in that direction," said Marcus.

P2P Validator Service Integrates with Avail Network
