abft

Well, Hedera Hashgraph implements Solidity smart contracts -- at >50,000 globally distributed public aBFT consensus (finalized) confirmations per second.

Hedera Hashgraph uses Proof-of-Stake consensus, stake weighting, aBFT and minimum stake threshold with node staking delegation.

Gossip-about-gossip and virtual voting combine to result in leaderless consensus, fair ordering and aBFT.

Paxos is nice, sure, but Hedera does DLT with aBFT and much more efficient, as well as being faster and ensuring fairness.

DLT technology discussions are entirely incomplete without consideration of Hedera Hashgraph [0], an aBFT, leaderless, fair and fast DLT using a gossip-about-gossip consensus mechanism.

It's aBFT consensus mechanism is built with KYC, real-time logging, can do 10^5 TPS vs Bitcoin and has finality in seconds across the network.

But Hashgraph aBFT may be implemented, if you need it.

Hashgraph improved on that to provide asynchronous BFT (aBFT) and deterministic finality and blocking on detection of lack of quorum, but: global consensus still necessarily fails either Availability or Consistency on Partitioning.

The idea of Hedera being the 'trust layer' of the internet is more about use cases like decentralized recovery, process validation, carbon offsets, extremely granular supply chain auditing, and any other application you might imagine that would benefit from having extremely fast (10k+ TPS), 100% guaranteed aBFT consensus on-chain.

Oh, hey there, Coventry:) I’d be curious to know the same, as well as to hear a comparison between Algorand and: 1) recent work on aBFT protocols, many of which don’t seem to require any kind of staking, and...
