Tech: [blockchain-object] - Signature validation

[andy-shi88]

Description

Blockchain object can be placed as a transaction sender. To validate transaction that has blockchain_object as a sender, we'll need to add a new account_type: AccountTypeBlockchainObject.

In signature validation, everytime we see a transaction comes from a blockchain object sender:

• look up into blockchain_object table, get the owner
• validate signature against its owner.

IF the owner of the blockchain object is another blockchain object, we will do another database lookup to get its owner, we'll set a restriction of blockchain-object as owner to 3 level.

• if we have look up 3 times and the owner is still blockchain object, then validation of signature fails.

Breakdown

• Add new account type
• Update signature validation for the new type.
