Golden Finance reported that Bitcoin Layer-2 network Stacks has launched the Satoshi upgrade, which aims to increase transaction speed and pave the way for the implementation of smart contracts. The upgrade separates Stacks' block generation schedule from Bitcoin and introduces a new way of block production, using the proof-of-transfer consensus algorithm. With this upgrade, users can burn Bitcoin (BTC) to mine Stacks blocks and receive rewards. Network operators have two weeks to implement the upgrade, after which a hard fork will be performed to complete the process. In addition, Stacks has launched sBTC, a bridge asset that allows users to transfer BTC to the Stacks economy. Despite the technical advances brought about by the upgrade, the STX token has fallen by more than 8% in the past 24 hours.
