ViaCoin is a cryptocurrency released in 2014, based on Bitcoin. It was the first cryptocurrency to implement the technology that would allow atomic swaps (trading between different blockchains without the need of an exchange) and the lightning network for faster transaction rates.
Its proof-of-work protocol enables "merged mining", that is, miners can work on any Scrypt coin's blockchain and ViaCoin's at the same time, resulting in a higher hashrate, and therefore more security, even when theShow more [+] reward is low.
