tezosprotocol

An implementation of the Tezos peer-to-peer communications protocol.

Supports offline fee calculation and the parsing, signing, and encoding of Tezos operations.

Installation

$ go get github.com/anchorageoss/tezosprotocol/v3

import"github.com/anchorageoss/tezosprotocol/v3"

Examples

Operation Parsing

Parsing a Tezos wire-format operation:

signedOperationBytes, _:=hex.DecodeString("e655948a282fcfc31b98abe9b37a82038c4c0e9b8e11f60ea0c7b33e6ecc625f6b0002298c03ed7d454a101eb7022bc95f7e5f41ac78e90901904e00004798d2cc98473d7e250c898885718afd2e4efbcb1a1595ab9730761ed830de0f6c0002298c03ed7d454a101eb7022bc95f7e5f41ac78d0860302c8010080c2d72f0000e7670f32038107a59a2b9cfefae36ea21f5aa63c0065667ade71f0c28dcd8c6f443be8b2ff9ebe9f3d2bd8a95d8a29df74319ef24e46bb8abe3e2553dec2a81353f059093861229869ad3c468ade4d9366be3e1308")
varsignedOperation tezosprotocol.SignedOperation_=signedOperation.UnmarshalBinary(signedOperationBytes)
fmt.Printf("%v\n", signedOperation)
operationHash, _:=signedOperation.GetHash()
fmt.Println(operationHash)

Operation Signing and Encoding

Creating, signing, and encoding a Tezos wire-format operation:

operation:=&tezosprotocol.Operation{
Branch: tezosprotocol.BranchID("BMTiv62VhjkVXZJL9Cu5s56qTAJxyciQB2fzA9vd2EiVMsaucWB"),
Contents: []tezosprotocol.OperationContents{
&tezosprotocol.Revelation{
Source: tezosprotocol.ContractID("tz1KqTpEZ7Yob7QbPE4Hy4Wo8fHG8LhKxZSx"),
Fee: big.NewInt(1257),
Counter: big.NewInt(1),
GasLimit: big.NewInt(10000),
StorageLimit: big.NewInt(0),
PublicKey: tezosprotocol.PublicKey("edpkuBknW28nW72KG6RoHtYW7p12T6GKc7nAbwYX5m8Wd9sDVC9yav"),
},
&tezosprotocol.Transaction{
Source: tezosprotocol.ContractID("tz1KqTpEZ7Yob7QbPE4Hy4Wo8fHG8LhKxZSx"),
Fee: big.NewInt(50000),
Counter: big.NewInt(2),
GasLimit: big.NewInt(200),
StorageLimit: big.NewInt(0),
Amount: big.NewInt(100000000),
Destination: tezosprotocol.ContractID("tz1gjaF81ZRRvdzjobyfVNsAeSC6PScjfQwN"),
},
},
}
privateKey:=tezosprotocol.PrivateKey("edskRwAubEVzMEsaPYnTx3DCttC8zYrGjzPMzTfDr7jfDaihYuh95CFrrYj6kyJoqYhycQPXMZHsZR5mPQRtDgjY6KHJxpeKnZ")
signedOperation, _:=tezosprotocol.SignOperation(operation, privateKey)
signedOperationBytes, _:=signedOperation.MarshalBinary()
fmt.Printf("%x\n", signedOperationBytes)

Protocol Upgrades

All backwards-incompatible changes will be handled via standard semantic versioning conventions. Separate tags for the latest stable release for each Tezos protocol will be maintained in parallel.

A separate go module will be published for each Tezos protocol upgrade to support applications migrating between the two.
