The reward consisted of a base reward of 5.000000000000000000 ETH ($11,836.90) with an additional 0.000000000000000000 ETH ($0.00) reward paid as fees of the 0 transactions which were included in the block web3.eth API¶ class web3.eth. Eth ¶. The web3.eth object exposes the following properties and methods to interact with the RPC APIs under the eth_ namespace.. Often, when a property or method returns a mapping of keys to values, it will return an AttributeDict which acts like a dict but you can access the keys as attributes and cannot modify its fields. For example, you can find the latest. So with your code it would be: You can now use the web3.eth.abi.decodeLog function (web3 1.0). You can use the tool ethereum-input-data-decoder for decoding transaction input data given the ABI. On new web3.js 1.0 you must use: web3.utils.toAscii (transaction.input)

How is it different than networkID? ChainID was introduced in EIP-155 to prevent replay attacks between the main ETH and ETC chains, which both have a networkID of 1.. It's basically just an additional way to tell chains apart. Subsequent to EIP-155, ETH has a chainID of 1, while ETC has a chainID of 61 (even though they still have the same networkID of 1) Bonsai trie initial sync fails with World State Root does not match expected value (testing only) #222 sha3Uncles: String, 32 Bytes - SHA3 of the uncles data in the block. logsBloom: String, 256 Bytes - the bloom filter for the logs of the block. transactionsRoot: String, 32 Bytes - the root of the transaction trie of the block; stateRoot: String, 32 Bytes - the root of the final state trie of the block. miner: String, 20 Bytes - the address of the beneficiary to whom the mining rewards were.
