Apply Blockchain

Last Updated: Jul 12, 2019

This topic describes how to apply to create or join the notary blockchain of Ant Blockchain.

  • You can apply to create consortium blockchains to deploy your own blockchains and become a blockchain administrator. An administrator can invite a user to join the blockchain as a consortium member. The administrator can also configure data classification to specify the data formats in a consortium blockchain.
  • If you are invited to join a blockchain as a consortium member, you can skip the preceding steps and directly apply to join a blockchain.
  • After you join a blockchain, you can see Ant Blockchain Development Guide to learn how to access the blockchain network and develop your business systems.

The notary blockchain will be offline on October 17, 2019. For a better experience, please use the contract blockchain, which has all the functions of the notary blockchain and better performance.
