This release continues the focus on Smart Contracts 2.0. The mirror node is useful for debugging a smart contract execution and our focus has been on providing APIs to make developers' lives easier. To that end, we added support for transaction ID nonce, a new contract logs REST API, and a new web3 API component.
The new Web3 API module provides an implementation of existing JSON-RPC APIs for the Hedera network. JSON-RPC API is a widely used standard for interacting with distributed ledgers. The aim in providing a Hedera implementation of these APIs is to ease the migration of existing dApps to Hedera and simplify the developer on-ramp. Currently, the Web3 module only provides a partial implementation of the Ethereum JSON-RPC API. Specifically, only the eth_blockNumber method has been implemented in this release as we focused on putting the groundwork in place first.
As part of HIP-32 and HIP-206 a nonce field was added to the TransactionID protobuf to guarantee uniqueness for platform generated transactions. This nonce field was added to any REST API that returns transaction data. A nonce query parameter was added to /api/v1/transactions/:transactionId, /api/v1/transactions/:transactionId/stateproof, and /api/v1/contracts/results/:transactionId to be able to distinguish between a user-submitted transaction and an internal transaction generated as a result of that transaction. Note that /api/v1/transactions/:transactionId without a nonce parameter will default to returning all transactions regardless of nonce while the other APIs will default nonce to 0.
The new /api/v1/contracts/{id}/results/logs REST API provides a search API to query for logs across contract executions for a particular contract. Searching by consensus timestamp and topics is supported. Note that for performance reasons it doesn't currently support pagination and requires a timestamp or timestamp range be provided to search by topic.
