Decred (Decentralized Credit) should be Bitcoin 2.0, as it appears to have adopted the most popular features of Bitcoin and paired them with better governance, limited miner influence and multi-chain atomic swaps to switch between different crypto-currencies.
Decred is a digital currency that offers complete autonomy to its stakeholders for decentralized decision-making and an easy transition between the different sets of rules. Its acronym is DCR, with a total supply of 21 million tokens.
The use of the Lightning Network (LN) allows almost instant micropayments in DCR. It is similar to Bitcoin, but processes in half the time and therefore competes with the existing fiat system.
