Getting Started with Vault

Since there is no Vault plug-in designed for the consortium chain, Vault-Blockchain came into being. Vault-Blockchain is a Vault plug-in developed by BSOS. It is completely designed for the consortium chain scenario and supplements the deficiencies of other Vault blockchain key management plug-ins. Its important functions are as follows: 1. Support of various signing methods: different consortium chain has different transaction formats, for example: in the enterprise Ethereum transaction, “_nonce_” needs to be part of the signature message; while the signature message in Fabric needs other information such as “_channelID_” and “_chaincodeID_”. Vault-Blockchain currently supports a variety of enterprise Ethereum clients such as Quorum / Besu, which are more versatile in function. 2. Support of private transaction signatures: The private transaction, which is unique to the consortium chain, requires additional parameters when signing, such as “privateFrom”, “privateFor” and “restriction” defined in EE. If the plug-in does not support these functions, even if the enterprise is connected to a consortium chain, it cannot execute the private transactions of the consortium chain. Vault-Blockchain not only supports the signature of different consortium chains, but also provides corresponding support for its private transactions to meet the needs of private transactions between enterprises. Vault-Blockchain is a vault plugin to generate and store Ethereum private keys. You can use it to sign transactions in Vault without revealing private keys.
