mcminterface v0.2.0b

Work In Progress! Beta for Mochimo 3.0!

This is a Golang library for interfacing with the MCM Network through the native socket/tcp protocol.
Written by NickP005

Usage

In query basics there is the main function you can test with. Compilation as usual with

go build

and then run the binary.

Or alternatively you can run the code with

go run .

There is a file, settings.json, that you can edit to change the startup settings. Below is an example of the file:

{
    "StartIPs": [
        "0.0.0.0"
    ],
    "IPs": [
        "0.0.0.0"
    ],
    "Nodes": [
        {
            "IP": "0.0.0.0",
            "LastSeen": "2024-08-05T12:54:28.9042045+02:00",
            "Ping": 792
        },
    ],
    "IPExpandDepth": 2,
    "ForceQueryStartIPs": false,
    "QuerySize": 5,
    "QueryTimeout": 5,
    "QueryRetries": 3
}

Examples

Interface startup

package main

import (
    "fmt"
    "github.com/NickP005/go_mcminterface"
)

func main() {
    go_mcminterface.LoadSettings("settings.json") // Load the settings from settings.json
    go_mcminterface.ExpandIPs()
    go_mcminterface.BenchmarkNodes(5) // Benchmark with 5 concurrent pings
    fmt.Println("Settings loaded and nodes benchmarked.")
}

Resolving a tag

func resolveTag() {
    tag := "0f8213c50de73ee326009d6a1475d1dba1105777"

    addr, err := mcminterface.QueryTagResolveHex(tag)
    if err != nil {
        fmt.Println("Error resolving tag:", err)
        return
    }
    // Print the bytes of the address
    fmt.Println("WOTS+ address bound to the tag:", addr.Address[:])

    // Print the amount of nanoMCM in the address
    fmt.Println("Balance:", addr.GetAmount())
}

Suggested Functions

Below there are the functions that are meant to be official: they query multiple nodes and return the most common result that is agreed by more than 50% of the nodes called.
Functions such as tag resolve haven't been implemented in query_manager.go yet, but are present in queries.go.

LoadSettings

Loads the settings from the settings.json file. For the code to properly work, ensure to call it before doing any QueryX function.

func LoadSettings() (SettingsType)

SaveSettings

Saves the settings to the settings.json file.

func SaveSettings(settings Settings)

BenchmarkNodes

Benchmarks all the nodes in the settings file. Useful at startup to determine the best nodes to query in later connections.

func BenchmarkNodes(n int)

n specifies how many concurrent pings to send.

ExpandIPs

Expands the IPs in the settings file.
Doing a benchmark after this function is recommended.

func ExpandIPs() ()

QueryBalance

Queries the balance of the specified full WOTS+ address given as hex.

func QueryBalance(wots_address string) (uint64, error)

QueryTagResolveHex

Queries the tag resolve of the specified tag given as hex.

func QueryTagResolveHex(tag string) (string, error)

QueryBlockFromNumber

Queries the block from the specified block number.
If the block number is 0, it will return the latest block.

func QueryBlockFromNumber(block_number uint64) (Block, error)

QueryLatestBlockNumber

Queries the latest block number.

func QueryLatestBlockNumber() (uint64, error)

GetTrailers

Queries the trailers of the specified block.

func GetTrailers(start_block uint32, count uint32) ([]BTRAILER, error)

Notes

The code is still in development and is not yet ready for production use.
Every query asks for QuerySize nodes that are picked by PickNodes. That function picks randomly the nodes, but nodes that have lower ping time are more likely to be picked!
