Despite its recent launch a little more than year ago, eCash is in fact a cryptocurrency with long history. It is a fork twice removed from the Bitcoin blockchain. However, the changes made to these blockchains since then make them seem like completely different cryptocurrencies.
eCash is actually an infamous BCHABC fork of Bitcoin Cash. The rebrand pursued two goals: to establish eCash as a means of payment and distance itself from the predecessors. The notoriety of BCHABC minority chain is due to the unpopular change that would redirect 8% of miner rewards to the rest of the network. The ticker BCH remained at the majority chain, and XEC went on to introduce even more radical changes to its own blockchain.
One of them is redenomination: 10 sats were changed to 1 XEC. Therefore, the total supply of XEC is 21 trillion. It undergoes halving every 240,000 thousand blocks just like Bitcoin and its forks do. eCash will be compatible with the Ethereum Virtual Machine and use Avalanche post-consensus, thus combining PoW and PoS.
