GadgetCoin is a modified partial implementation of the Ethereum specification in Rust. The original specification is available via the Ethereum white paper and yellow paper.
We have added some instructions to the Ethereum ISA via previously unused opcodes. For convenience, stack items are only 8 bits rather than the standard 256, and smart contracts have been removed - instead, arbitrary Turing-complete code can execute directly from a user-supplied transaction.
The goal of this project was to learn about Rust and Ethereum while benchmarking the performance of different concurrent and sequential implementations of nonce computation and blockchain verification.
Use cargo bench to compile the code and run benchmarks.
