Bitcoin Core 0.12.1 Released, Major Step Forward for ScalabilityBitcoin Core 0.12.1 was released early this morning and the update includes several changes that have huge implications for Bitcoin scalability. The release deploys the first soft fork on the Bitcoin network to use the methodology outlined in BIP 9 (Version Bits), which allows multiple soft forks to take place at the same time.
The three BIPs (BIP 68, BIP 112 and BIP 113) included in Bitcoin Core 0.12.1 have huge implications for the Lightning Network, which many believe to be Bitcoin’s best chance for long-term scalability. Although the code for the soft fork has been deployed, miners cannot signal their support for it until May 1st.
