- implement Ethereum straight from the Yellow Paper
- (over)simplify things at first for a quick implementation
- no EVM/real contracts for now
- compatibility with real Ethereum: maybe later if at all
- create a small browser game on top of it to teach the basics of Ethereum
There are structs that should cover most necessary data structures, a bit of validatation and execution logic here and there, and a few JSON RPC methods. Almost ready to send transactions...
teth uses many of the same utility crates as parity-ethereum (such as rlp, patricia-trie, tiny-keccak and ethereum-types), but otherwise aims to be an independent implementation of the specification. Also, parity-ethereum is quite large (~143k LoC) and has many options; teth will remain small and just implement the specification in a straight-forward manner.
NOTE: Almost every command will fail with 'not implemented yet' at the moment!
