Open Source Blockchain Platforms

This entry catalogs major open source blockchain platforms as potential components of Open Source Finance (See here for a review of the blockchain software concepts)

A blockchain denotes a network based software system and protocols that enable "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way". This design is at the core of various virtual / crypto currencies but it is considered more broadly applicable.

Classification

There are various types of blockchain networks:

By Access Type

  • Public Blockchains: A public blockchain has no access restrictions.
  • Private (Permissioned) blockchains: A private blockchain is permissioned. Membership is by invitation.
  • A hybrid blockchain has a combination of centralized and decentralized features.

By Use

Blockchain technology can in principle be applied in multiple areas:

  • The primary use of blockchains continues to be for cryptocurrencies
  • Back office settlement
  • In supply chain logistics and supply chain management
  • As general public ledger for compiling data
