What are the different features of OpenChain?
Here are some exciting features of OpenChain:

- No Mining Fee
In the OpenChain network, all transactions are validated by the administrator rather than the miners. So there is no mining fee involved. All transactions on OpenChain are validated in real-time by the administrator.

- Security
All transactions on OpenChain are secured by using digital signatures. A digital signature is assigned to each and every transaction which binds it to the digital data on the ledger.

- Immutability & Scalability
Just like any other distributed ledger technology, OpenChain forms an immutable record of transactions i.e no modification is permissible once the data is added to the ledger. Also, the Blockchain is easily expandable to accommodate any number of transactions.

- Multi-signature Support
OpenChain also supports multi-signature transactions. Permissions are granted through a list of public keys and a number of required signatures.

What are the use cases of OpenChain in different industries?
The OpenChain technology is disrupting many industries like

  1. Supply Chain
  2. Property & Real Estate
  3. Cryptocurrency Exchange
  4. Banking
  5. Legal Industry
