This is a rudimentary, soon to be improved, site for tracking BlockChain hardforks :)
Beam is a confidential and scalable cryptocurrency based on the MimbleWimble protocol. Hardforks occur as part of a policy to prevent the introduction of ASICs to their network.
Bitcoin was one of the first implementations of the Cryptocurrency concept, created by Satoshi Nakomoto in 2009. It remains one of the most popular cryptocurrencies. Bitcoin Hardforks are usually rare and are the result of a disagreement in the currencies direction.
