According to CoinDesk, Elastos, a blockchain project, has announced the BTC Oracle, a solution that aims to enable every EVM-compatible blockchain to function as a Bitcoin L2. This is considered the most comprehensive solution for cross-chain operability involving Bitcoin and EVM blockchains to date. The BTC Oracle is part of Elastos's BTC L2, 'BeL2,' which is the first BTC L2 to enable the direct development and management of Bitcoin-native smart contracts. Elastos' BTC Oracle acts as a zero-knowledge proof data feed that provides real-time Bitcoin information to EVM smart contracts. A prototype is now available, demonstrating how users can stake ELA in return for Bitcoin rewards. The announcement of the BTC Oracle is a significant step forward in the development of cross-chain operability between Bitcoin and EVM-compatible blockchains, potentially opening up new possibilities for decentralized applications and financial services.
