Tracking issue for Oracle Nodes #8

Open longtomjr opened 2 years ago

longtomjr commented 2 years ago

Tasks

[ ] Add oracle node binary that exposes an HTTP interface that reads information from Algorand and signs the resulting authorization data

Implementation Plan

[ ] use algonaut to read blockchain Algorand blockchain state (Testnet) through PureStake APIs #18
[ ] Look at signing algorithms and Define/Build the protocol
[ ] Add HTTP interface/endpoint
[ ] Sign the resulting authorization data response

Authorization Data Struct:

Name	Type	Description	How
redeemed	bool	Confirmation that the DRT have been redeemed correctly	Check destination address is same as reserve address of the DRT - check txn receiver is same as reserve address on DRT
drt_creator	Algorand Address	The Address or other cryptographic identifier that indicates who created the DRT	Get management address from asset_id
drt_redeemer	[u8;32]	The public key of the party that redeemed the DRT	From txn_id, lookup account of receiver to get public key
executable_hash	hash (sha512_256)	Information encoded in the DRT	From asset_id, find creation transaction, take note hashes
data_package_hash	hash (sha512_256)
executable_url	&str
data_package_url	&str

Signed Authorization Data Struct:

Name	Type	Description	How
signature	byteArray	Sign Auth Data	Use private key of oracle node (can be stored as env variable) and sign serialized authdata value
auth_data	AuthData

Functions: get_auth_data(txn_id, asset_id) -> AuthData sign_auth_data(auth_data) -> SignedAuthData
