What is Openchain?

Openchain is an open source distributed ledger technology. It is suited for organizations wishing to issue and manage digital assets in a robust, secure and scalable way.
  • Anyone can spin up a new Openchain instance within seconds.
  • The administrator of an Openchain instance defines the rules of the ledger.
  • End-users can exchange value on the ledger according to those rules.
  • Every transaction on the ledger is digitally signed, like with Bitcoin.

Blockchain technology, supercharged

How does it work?

The consensus mechanism used by Openchain differs from other Bitcoin-based systems, it uses Partionned Consensus:
  • Every Openchain instance only has one authority validating transactions.
  • Instead of one single central ledger, each organization controls their own Openchain instance. Instances can connect to each other.
  • Different transactions will be validated by different authorities depending on the assets being exchanged.
  • Every asset issuer has full control on the transactions relevant to that asset.

More efficient

Openchain is more efficient than systems that use Proof of Work:
  • Openchain uses a client-server architecture which is more efficient and reliable than a peer-to-peer architecture.
  • There is no miner, transactions are directly validated by the asset administrator.
  • Since there is no miner, transactions are instant and free.

Modular design

  • Validators validate and store transactions.
  • Observers receive a read-only copy of the ledger. They do their own validation of the ledger and store their own copy.
  • Validators and observers expose standard HTTP-based APIs.
  • Clients and wallets connect to validators to submit digitally signed transactions.
  • Smart contracts are independent actors receiving and sending transactions according to arbitrary business logic.
  • Gateways create 2-way pegging between two Openchain instances. They can also peg the Openchain instance as a sidechain of the Bitcoin Blockchain.

What are the use cases?

Openchain is a generic register of ownership. It can be modelled to work with an immense number of use cases:
  • Securities like stocks and bonds, commodities like gold and oil, currencies like the Dollar or even Bitcoin.
  • Titles of ownership like land titles, music or software licensing.
  • Gift cards and loyalty points.

Try the wallet

Because an Openchain node exposes a simple HTTP endpoint, it's easy to build a wallet or client application, but we are providing a basic open source wallet for testing purposes.
Try the basic Openchain wallet. Connect to the development server provided by Coinprism, or see below to spin up your own server. 
$ git clone https://github.com/openchain/docker.git openchain
$ cd openchain
$ cp templates/server.yml docker-compose.yml
$ mkdir data
$ cp templates/config.json data/config.json
$ nano data/config.json
$ docker-compose up -d

Create your own server instance

It only takes a few seconds to spin up a new instance of Openchain server.
  • Create an instance, and use it to issue your own digital asset, and distribute it to people.
  • Openchain is free and open source: you don't have to spend or buy any crypto-currency to use it.
