Hyperledger Sawtooth is Ready for Business

Intel’s "Hyperledger Sawtooth" version 1.0 released
30 January 2018   1232

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.

The final version also supports Solidity smart contract language, along with Go, Javascript, Python. Among the early companies who already use Hyperledger Sawtooth are Huawei, T-Mobile and Amazon.

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”.

Accenture to File New Blockchain Patent

Technology, developed by the team, seeks to improve blockchain's security and stability

Accenture, which works in the field of consulting and professional services, filed a patent application describing the technology of "Hardware blockchain accleration", designed to accelerate and improve the security of transactions in the blockchain using patented equipment. This is reported by CCN.

According to Accenture, this technology is necessary in connection with the new security threats that have emerged due to the rapid development of communication and electronic technologies. The patent application states that this technology provides safe and efficient execution of complex transactions not only between software processes and hardware systems, but also between people.

Accenture says its invention improves the security and scalability of the blockchain due to the fact that the encryption and decryption of data is carried out not only in hardware but also programmatically, so that the technology is not limited to either way.

As a result, the implementation shown … has increased security and scalability as compared to, for example, software only based security systems. For example, all or parts of the implementations may be circuitry that includes an instruction processor, such as a Central Processing Unit (CPU), microcontroller, or a microprocessor; or as an Application Specific Integrated Circuit (ASIC), Programmable Logic Device (PLD), or Field Programmable Gate Array (FPGA); or as circuitry that includes discrete logic or other circuit components, including analog circuit components, digital circuit components or both; or any combination thereof.
 

Accenture Patent Application

Instructions for performing tasks can be stored on various media, including flash memory, magnetic and optical disks like hard disks, CD-ROMs, as well as EPROM, ROM and RAM.

Earlier, the company developed a blocking prototype, which allows administrators to edit, rewrite and even delete blocks from closed blockchains. Then one of the leaders of Accenture, Richard Lamb, said that the absolute immutability of the block could not suit financial institutions like banks.
