EthereumJS Recap October 2018
Recap for EthereumJS is a bit overdue. September was a bit of a lazy month, so we skipped this one, then there was Devcon4 and I was thinking about broadening the format of posts and not just write down on new releases, which also caused some delay.
This is the first post on medium, following up the last one directly published on Reddit. So what’s happened?
EthereumJS Client: Libp2p and Browser Sync
Don’t want to make this post to opinionated, but for me this was by far the most exciting stuff during the last weeks: Vinay has merged libp2p support in PR #56 and browser support in PR #59 into master of the currently in development ethereumjs-client project.
This allows for setting up an ethereumjs-client node having listeners open for both RLPX and libp2p connections, which then fast-syncs the chain from the existing Ethereum network. With this in place another node can be started in light-sync mode within the browser connecting to that first node via libp2p and storing the chain in the local browser leveldb database.
We had various releases preparing for Constantinople:
ethereumjs-util v6.0.0 now has a new generateAddress2() function for CREATE2 opcode (EIP-1014) address creation, this release also drops the previously deprecated sha3-named constants and methods.
Furthermore there was a bugfix release v2.3.2 for the merkle-patricia-tree library (bugfix in verify proof, internal variable leak fix). No Constantinople reference, this should nevertheless be mentioned as well. :-)
New Labelling System
We have a new labelling system in place, it looks like this for issues on the VM…
This should help contributors and current core developers a lot on judging what issues to pick to work on and keep conversation around issues going.
Talk on EthereumJS and Sharding
There has been loads of work on the ethereumjs-vm repo lately and we are closing in for a release with Constantinople support, a reworked StateManager and huge improvements regarding consensus conformance. More on this in the next update, if you want to follow the release process have a look here.
And finally: one big part in our roadmap for the next year respectively the coming months will be a major transition of our libraries to TypeScript. This is to improve type safety and therefor overall security and reliability of the libraries.
That’s it folks. Happy buidling and see you next month!
