Bitcoin cash airdrop

A hard fork in blockchain technology refers to a significant change in the protocol that validates previously invalid blocks or transactions, requiring all nodes or users to upgrade to the latest software version. This results in a permanent split from the previous blockchain version, with one path following the upgraded blockchain and the other continuing along the old one. Eventually, users on the old chain usually transition to the new version. If both chains gain support, it can lead to the creation of two separate coins. The one megabyte block size limit was originally intended to prevent spam and DDoS attacks. However, as the number of Bitcoin transactions increased, this limit caused delays in block processing, leading to extended confirmation times. The issue peaked in May 2017 when users had to wait days for confirmations. While users could pay higher fees to speed up confirmations, this made Bitcoin impractical for smaller transactions.
