Rethinking Proof of Work: The Quest to ‘Improve’ Bitcoin Heats Up
The system that secures bitcoin, proof of work, demands vast amounts of energy – and that's a prize problem to solve, say researchers.
Though it's garnered little attention, "non-interactive proofs of proofs of work" may clear a roadblock for sidechains, a potential "altcoin killer."
A plan to hard fork the bitcoin blockchain, and change its mining algorithm, is emerging. Still in its early stages, what does the new coin offer?
Spacemesh's "proof-of-space-time" (PoST) consensus protocol hopes to do away with mining pools and expensive GPU or ASIC-based miners.
Bitcoin's 'proof of work' validation mechanism burns a huge amount of energy, but this novel solution from developer Bram Cohen aims to change that.
Bitcoin's consensus mechanism is great, but it isn't perfect. This article looks at some of the more viable public blockchain alternatives.
