Changelog

Unreleased

(sdk) #386 Bump Cosmos SDK version to v0.39.1
(x/evm) #181 Updated EVM module to the recommended module structure.
(app) #188 Misc cleanup:
- (x/evm) Rename EthereumTxMsg --> MsgEthereumTx and EmintMsg --> MsgEthermint for consistency with SDK standards
- Updated integration and unit tests to use EthermintApp as testing suite
- Use expected Keeper interface for AccountKeeper
- Replaced count type in keeper with int
- Add SDK events for transactions
#236 Changes from upgrade:
- (app/ante) Moved AnteHandler implementation to app/ante
- (keys) Marked ExportEthKeyCommand as UNSAFE
- (x/evm) Moved BeginBlock and EndBlock to x/evm/abci.go
(x/evm) #255 Add missing GenesisState fields and support ExportGenesis functionality.
#272 Add Logger for evm module.
#317 GenesisAccount validation.
(x/evm) #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) #325 eth_coinbase JSON-RPC query now returns the node's validator address.

(build) #378 Create multi-node, local, automated testnet setup with make localnet-start.
(rpc) #330 Implement PublicFilterAPI's EventSystem which subscribes to Tendermint events upon Filter creation.
(rpc) #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) #54, #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) #187 Add support for simulations.

(rpc) #305 Update eth_getTransactionCount to check for account existence before getting sequence and return 0 as the nonce if it doesn't exist.
(x/evm) #319 Fix SetBlockHash that was setting the incorrect height during BeginBlock.
(x/evm) #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.
