Besu Views

  • RFC: 03-005
  • Authors: Sandeep Nishad, Dhinakaran Vinayagamurthy, Venkatraman Ramakrishna, Krishnasuri Narayanam
  • Status: Draft
  • Since: 05-Jan-2023

Summary

This document specifies the design of view address for remote query to Besu networks, and the structure of Besu View which is returned as response of the remote query.

Addressing a Besu View

operator = ledger-id , ":" , contract-name/address , ":" , func-name-with-signature , [ ":" , { argument } ] ;

ledger-id is empty in case of Besu.

Example:

  • ledger-id: _ (indicating empty)
  • Contract Name: SimpleState
  • Function Name: get(string)
  • Arguments: key
operator = _:SimpleState:get(string):key

View Data Definition

  1. Interop payload in bytes (check if the requestor can directly obtain this from the output merkle-patricia-trie proof verification)
  2. Header fields of block object (this also contains receiptsRoot).
  3. Merkle-Patricia Proof
  4. Index of receipt object of interest -> txRIndex.
  5. LogIndex
  6. Signatures of validators from extraData (we can obtain a validator's public key from its signature using recover)
