July 25: BitcoinOS, a community of Bitcoin-based rollup chains, has verified the first-ever zero-knowledge (ZK) proof on Bitcoin’s mainchain. ZK cryptography is appeared to as a key know-how for scaling blockchain throughput and usefulness, however the tech is difficult and computationally intense – that means it was unclear if or when it will make its solution to the comparatively bare-bones Bitcoin community. In keeping with the BitcoinOS crew, “That is the primary permissionless improve of the Bitcoin system and the primary time Bitcoin has been upgraded with no tender fork.” Bitcoin can now be “infinitely upgradable,” the crew informed CoinDesk, “whereas requiring no adjustments to the consensus code.” BitcoinOS goals to be the “final implementation of a Bitcoin rollup system,” ultimately serving as a bridge connecting any variety of rollups – fast and low cost layer-2 blockchains which can be secured by the Bitcoin blockchain and ZK proofs.
