This page has moved to https://docs.blockscout.com/user-instructions/untitled/evm-version-information
When verifying a smart contract in Blockscout you will provide the EVM version the contract uses. If the bytecode does not match the version, we try to verify using the latest EVM version.
For more information, see the Solidity docs on specifying the EVM version when compiling a contract. Note that backward compatibility is not guaranteed between each version.
| Name | Date | Mainnet Block # | Relevant changes / opcode specs | EIP details | |
|---|---|---|---|---|---|
| 1 | Homestead | 2016-03-14 | 1,150,000 | Oldest version | http://eips.ethereum.org/EIPS/eip-606 |
| 2 | Tangerine Whistle | 2016-10-18 | 2,463,000 | Gas cost to access other accounts increased, impacts gas estimation and optimization. All gas sent by default for external calls, previously a certain amount had to be retained. |

| 3 | Spurious Dragon | 2016-11-18 | 2,675,000 | Gas cost for the exp opcode increased, impacts gas estimation and optimization. |

| 4 | Byzantium | 2017-12-17 | 4,370,000 | Opcodes returndatacopy, returndatasize and staticcall available in assembly.staticcall opcode used when calling non-library view or pure functions, which prevents the functions from modifying state at the EVM level, this even applies to invalid type conversions.Ability to access dynamic data returned from function calls. revert opcode introduced, revert() will not waste gas. |

| 5 | Constantinople | 2019-02-22 | 7,280,000 | Opcodes create2, extcodehash, shl, shr and sar are available in assembly.Bitwise shifting operators use shifting opcodes ( shl,shr,sar), requiring less gas. |
