ethereumjs-common - npm Package Versions

[1.0.0] - 2019-01-23

First TypeScript based release of the library (for details see PR #38), so release coming with type declaration files and additional type safety! 😄

Breaking Changes

Library Import

TypeScript handles ES6 transpilation a bit differently (at the end: cleaner) than babel so require syntax of the library slightly changes to:

const Common = require('ethereumjs-common').default

Genesis State Import/Usage

Import path and usage API of genesis state has changed, see also the docs on this, PR #39:

const mainnetGenesisState = require('ethereumjs-common/dist/genesisStates/mainnet')

Or by accessing dynamically:

const genesisStates = require('ethereumjs-common/dist/genesisStates')
const mainnetGenesisState = genesisStates.genesisStateByName('mainnet')
const mainnetGenesisState = genesisStates.genesisStateById(1) // alternative via network Id

Removed hybridCasper (draft) hardfork

Not likely that anyone has used this, but just in case: The once anticipated hybridCasper (draft) hardfork has been removed from the list of hardforks, see PR #37

[0.6.1] - 2018-11-28

• Experimental support for the Goerli cross-client PoA testnet (chains/goerli.json), see PR #31
• Unified hex-prefixing (so always prefixing with 0x) of account addresses in genesis files (fixes an issue with state root computation on other libraries), see PR #32

[0.6.0] - 2018-10-11

Parameter support for the Constantinople hardfork (see hardforks/constantinople.json):

• Added SSTORE gas/refund prices (EIP-1283), PR #27
• Added Block Reward Adjustment (EIP-1234), PR #26

[0.5.0] - 2018-08-27

• Introduces support for private chains by allowing to pass a custom dictionary as the chain parameter in the constructor or the setChain() method as an alternative to just passing one of the predefined chain String names (e.g. mainnet, ropsten), PR #24

[0.4.1] - 2018-08-13

• Added timestamp field to genesis definitions in chain files, set for Rinkeby and null for other chains, PR #21
• Updated Ropsten bootstrap nodes, PR #20

[0.4.0] - 2018-06-20

• Remove leftover ...Gas postfix for some gas prices (e.g. ecAddGas -> ecAdd) to be consistent with overall gas price naming

[0.3.1] - 2018-05-28

• Added two alias functions activeOnBlock() and gteHardfork() when hardfork is set for convenience, PR #15
• Added option to dynamically choose genesis state (see README), PR #15

[0.3.0] - 2018-05-25

• Allow functions like hardforkIsActiveOnBlock() - where hardfork is provided as param - also to be run on hardfork set for greater flexibility/comfort, PR #13
• New hardforkGteHardfork() method for HF order comparisons, PR #13

[0.2.0] - 2018-05-14

• New optional initialization parameter allowedHardforks, this allows for cleaner client library implementations by preventing undefined behaviour, PR #10
• Added activeHardfork() function to get latest active HF for chain or block, PR #11

[0.1.1] - 2018-05-09

• Remove dynamic require to prevent browserify issue, PR #8
