What is HyperLedger? 

Hyperledger is an umbrella project of open source blockchains and related tools, started in December 2015 by the Linux Foundation, to support the collaborative development of blockchain-based distributed ledgers. Hyperledger is designed to create enterprise grade, open source, distributed ledger frameworks and code bases to support business transactions.

One of the first question that rises when studying Hyperledger is "Are blocks mined in HyperLedger?" And the answer is no. Let's figure out, why. 

Hyperledger Validating Peers (VPs) do not mine blocks and do not share the blocks between them. Here is how it works:

  1. A transaction is send to one trusted VP.
  2. The VP broadcasts the transaction to all other VPs.
  3. All VPs reach consensus (using PBFT algorithm) on the order to follow to execute the transactions.
  4. All VPs execute the transactions "on their own" following the total order and build a block (calculating hashes mainly) with the executed transactions.

All the blocks will be the same because: the transaction execution is deterministic (should be) and the number of tx in a block is fixed.

Accenture to File New Blockchain Patent

Technology, developed by the team, seeks to improve blockchain's security and stability
08 August 2018   263

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.
