• (evm) tharsis#319 Various evm improvements:
  • Add transaction []*ethtypes.Logs to evm's GenesisState to persist logs after an upgrade.
  • Remove evm CodeKey and BlockKeyin favor of a prefix Store.
  • Set BlockBloom during EndBlock instead of BeginBlock.
  • Commit state object and Finalize storage after InitGenesis setup.
• (rpc) tharsis#325 eth_coinbase JSON-RPC query now returns the node's validator address.

Features

• (build) tharsis#378 Create multi-node, local, automated testnet setup with make localnet-start.
• (rpc) tharsis#330 Implement PublicFilterAPI's EventSystem which subscribes to Tendermint events upon Filter creation.
• (rpc) tharsis#231 Implement NewBlockFilter in rpc/filters.go which instantiates a polling block filter
  • Polls for new blocks via BlockNumber rpc call; if block number changes, it requests the new block via GetBlockByNumber rpc call and adds it to its internal list of blocks
  • Update uninstallFilter and getFilterChanges accordingly
  • uninstallFilter stops the polling goroutine
  • getFilterChanges returns the filter's internal list of block hashes and resets it
• (rpc) tharsis#54, tharsis#55 Implement eth_getFilterLogs and eth_getLogs:
  • For a given filter, look through each block for transactions. If there are transactions in the block, get the logs from it, and filter using the filterLogs method
  • eth_getLogs and eth_getFilterChanges for log filters use the same underlying method as eth_getFilterLogs
  • update HandleMsgEthereumTx to store logs using the ethereum hash
• (app) tharsis#187 Add support for simulations.

Bug Fixes

• (evm) tharsis#767 Fix error of timeout when using Truffle to deploy contract.
• (evm) tharsis#751 Fix misused method to calculate block hash in evm related function.
• (evm) tharsis#721 Fix mismatch block hash in rpc response when use eth.getBlock.
• (evm) tharsis#730 Fix 'EIP2028' not open when Istanbul version has been enabled.
• (app) tharsis#749 Fix panic in AnteHandler when gas price larger than 100000
• (rpc) tharsis#305 Update eth_getTransactionCount to check for account existence before getting sequence and return 0 as the nonce if it doesn't exist.
• (evm) tharsis#319 Fix SetBlockHash that was setting the incorrect height during BeginBlock.
• (evm) tharsis#176 Updated Web3 transaction hash from using RLP hash. Now all transaction hashes exposed are amino hashes:
  • Removes Hash() (RLP) function from MsgEthereumTx to avoid confusion or misuse in future.
