History of Permissioned Ledgers

Primarily to be focused on the development of permissioned ledgers, but including some general enterprise stuffs while I get my timeline together.

I used this space to prep for writing this article:

If you are looking at this, and the above article, thinking: “I really would love a more detailed report” feel free to contact me so we can discuss your needs.

Early use, and discussion of “Distributed Ledger”

Monax - Eris

—the first open-source permissioned blockchain

  • $100,000 bounty was announced for the creation of a software platform to replace the Bitcoin Foundation, out of concerns over a lack of transparency

I’m into blockchains, having been a founder and former COO of Monax. Monax built the first open-source permissioned blockchain client in 2014. The design has since evolved into the market-leading Hyperledger Burrow permissioned Ethereum blockchain node. Burrow is presently the Hyperledger Project’s only Ethereum Virtual Machine (EVM), and is used by Intel and IBM’s contributions to that project, Sawtooth and Fabric, to run EVMs on those codebases.

They didn’t win the bounty, but their open-source permissionable implementation of the Ethereum Virtual Machine (EVM) was submitted to the Hyperledger Foundation under the name Burrow, and has helped any number of people and organizations experiment with a blockchain virtual machine.

Evernym-Sovrin

Around the same time, Evernym published its initial identity white paper and began its work on [Plenum], an implementation of RBFT consensus, supporting the development of a decentralized public key infrastructure (DPKI).

In September, the open-source Sovrin codebase was donated to the Sovrin Foundation: a private-sector, international non-profit established to govern a global public utility for self-sovereign identity.

Quorum

10/2016, JP Morgan announced their development of Quorum, a permissioned version of Ethereum supporting data privacy to enable interaction between public and private blockchains and allowing for private, secure, peer-to-peer transactions.

R3 - Corda

11/16, R3 open-sourced Corda, it’s permissioned distributed ledger platform. Corda features private transactions and smart contracts based upon Smart Contract Templates: foundations, design landscape, and research directions, Barclays, University College London.
