Proof-of-work (PoW) is used as the consensus mechanism in most cryptocurrencies. PoW-based puzzles play an important part in the operation and security of a cryptocurrency, but come at a considerable energy cost. One approach to the problem of energy...

Blockchain-based replicated ledgers, pioneered in Bitcoin, are effective against double spending, but inherently attract centralised mining pools and incompressible transaction delays. We propose a framew... Read More about Graphchain: A blockchain-free scalable decentralised ledger.
