Hands on Blockchain

evm-dev-station

Currently ALPHA(ALPHA(ALPHA(ALPHA())))

git clone this repo and run ./evm-dev-station. Its a fat binary, so it works on both intel and apple silicon based darwin machines.

work flow

You can run EVM code/deploy contracts immediately against in memory state OR you can load up a blockchain database and use that.

Only works with geth created leveldb or pebble based databases (and currently just tested with pebble based db)

1. You load up a database via the button called Load Chaindata this is the chaindata directory inside your geth --datadir. Don't use the currently running one, instead make a copy so you can operate on a snapshot of the blockchain. Aka if your datadir parameter to geth was --datadir=/mnt/0ae570e6-4377-47fa-bc8e-21fc1ed96974/home/mev/eth-mainnet/chaindb then stop it momentarily and make a copy of /mnt/0ae570e6-4377-47fa-bc8e-21fc1ed96974/home/mev/eth-mainnet/chaindb/geth/chaindata aka the chaindata. This is your database directory we'll use
2. in the Load Chaindata button in the upper right, you give the path to the directory with the copied chaindata
3. Load contracts from the left hand side list, the Load from chain with optional ABI.
4. Give input data if any, hit Run Contract

ideas, feedback

Huge amounts of bugs. Yes its currently closed source, but still open tickets, issues with screenshots please showing what happened wrong. I'll add a git commit to the UI so we can double check what version you had issues with. Right now its probably more useful to tell, share ideas about what you'd like to be able to do, see, how it ought to interact, font changes, animations etc.

talking to myself

OMG AppStorage super annoying to test AppStorage again

$ rm -rf ~/Library/Preferences/evm-dev-station-x86.plist
$ killall -u $(whoami) cfprefsd

infoplist stuff

      linkerSettings: [
        .unsafeFlags( ["-Xlinker", "-sectcreate",
                       "-Xlinker", "__TEXT",
                       "-Xlinker", "__info_plist",
                       "-Xlinker", "Resources/Info.plist"] )
      ]),

otool -P .build/debug/evm-dev-station will show that plist

architecture

golang compiled into a C static library, statically linked into native swift binary.

evm-dev-station's Issues

Create a Universal Binary instead of two separate binaries

Maintaining two separate binaries is unnecessary now with the way you can make a smaller Universal Binary out of the two build outputs.

Support mounting remote storage

There are several ways to do this, the benefit is that (for me at least) I can access geth archive state from our production replication service. Geth requires a beacon client to sync to mainnet, which makes it more cumbersome, at least for mainnet use case.

I am refering to SSHFS, etc. Not S3.
