ChainCatcher news, according to Coindesk, the decentralized trading platform Uniswap has been forked by developers after its BSL expired on April 1. It is reported that the open-sourcing of its code starting from April 1 of this year was calculated after the upgrade to version V3 in 2021, as the license is valid for only two years. According to DefiLlama data, PancakeSwap AMM V3 currently has a TVL of $125 million.It is reported that BSL stands for Business Source License, and software using the BSL protocol will change to an open-source protocol after a maximum of 4 years from release (developers can customize the open-source time in the protocol, and Uniswap specified it as 2 years when releasing version V3). That is, software using the BSL protocol will ultimately become open-source software. (Source link)
