# Eth-state-transition

Ethereum state transition function.

## Usage

```golang

import (

    itrie "github.com/0xPolygon/eth-state-transition/immutable-trie"

    "github.com/0xPolygon/eth-state-transition/runtime"

    state "github.com/0xPolygon/eth-state-transition"

)

func main() {

    // get a reference for the state

    state := itrie.NewArchiveState(itrie.NewMemoryStorage())

    snap := s.NewSnapshot()

    // create a transition object

    forks := runtime.ForksInTime{}

    config := runtime.TxContext{}

    transition := state.NewTransition(forks, config, snap)

    // process a transaction

    result, err := transition.Write(&state.Transaction{})

    if err != nil {

        panic(err)

    }

    fmt.Printf("Logs: %v\n", result.Logs)

    fmt.Printf("Gas used: %d\n", result.GasUsed)

    // retrieve the state data changed

    objs := transition.Commit()

    // commit the data to the state

    if _, err := snap.Commit(objs); err != nil {

        panic(err)

    }

}
