Today it was revealed that Hyperledger Sawtooth is officially ready for enterprise use. It is now also the second open-source blockchain platform after Hyperledger Fabric.
With the release, Sawtooth marks the business debut of a new consensus mechanism called “proof-of-elapsed-time” (PoET). So, instead of having the participants to solve a cryptographic puzzle, the algorithm uses special processor instructions to ensure new blocks are produced randomly like a lottery; no work required. Potentially, anybody with the CPU that supports new instruction is eligible to be part of the consensus process, and it is very energy-efficient.
This very instruction also provides hardware security solutions for enterprises that want to integrate Sawtooth into its business line. Thus, Intel delivers a balance between utilizing the strengths of a public blockchain with transaction volume and enterprise security demands.
As for the reactions on social networks, some Twitter users were sarcastic: @MadBitcoins said “How is this breaking?”; and @kgorin said “Does it leak memory too?”. Some were optimistic: @minigin_courses said “Sweet!!!! $btc #Bitcoin”.
