scriptnetwork/script-4 ? reverse-engineered prompt

Build me a Go based blockchain ledger for Script that I can run locally as a node and interact with from a command line wallet.

I want it to support Proof of Stake style consensus, fast block confirmation, transaction handling, a mempool, networking between nodes, and basic RPC so I can query the chain and send transactions. It should also include wallet tools for creating accounts, checking balances, and moving tokens around, plus support for smart contracts since this chain is meant to be EVM compatible.

Make it easy to build with a simple make install, and include tests I can run locally. If anything needs current setup details or dependencies, look up the latest docs online first. I also want the code organized so it can be run as a full node and a separate CLI tool, with sensible defaults for a local test network.
