First Block Mined Today
The Bitcoin.com pool mined its first block, block 430757, on Wednesday September 21, 2016.
This is a significant day in Bitcoin history, and one for future Bitcoiners to remember. While mining pools have come and gone over the years, this is important because Bitcoin.com uses the Bitcoin Unlimited protocol.
Bitcoin Unlimited is an alternative to the Bitcoin Core protocol most Bitcoin miners use. Unlimited’s key difference is it removes transaction block size limits from the protocol level and adds it to the transport level. This means those running the software can choose the size they like.
