Build Your Own Decentralized Network with simplep2p-rpc-service

Hello everyone,  🚀 Today, we dive deep into a new framework I've developed: the "Simple P2P RPC Service". This platform aims to redefine how we perceive peer-to-peer (P2P) communication in the tech world. Let's get started.

Understanding Simple P2P RPC Service

At its core:

RPC: Remote Procedure Call (RPC) allows one program to request a service without having to understand the network's details. In this context, it's about one computer asking another to perform a computation.

P2P Network: This is a decentralized network where all participants (peers) have equal authority and collaborative capabilities.

The Core Project: A Decentralized Calculator

I've developed a calculator with a unique twist: it doesn't perform calculations locally. Instead, it delegates tasks to other computers in the network. For instance, if a user wants to calculate 3 + 5, the request might be sent to another computer in the network, say Alice's. Alice's machine computes the result, sends it back, and the user receives the answer.

Implementing the Simple P2P RPC Service

To integrate this service into your projects:

Set up the framework in your preferred workspace.

git clone https://github.com/hackable/simplep2p-rpc-service.git

Run the command npm install to fetch all necessary dependencies.

Key Functionalities

Service Control: The start() and stop() methods allow you to dictate the service's operation within the network.

Making a Computation Request: To request a computation, for instance, from Alice's computer, use:

const response = await rpcService.request(alicePeerId, 'add', [3,5]);
console.log("Response:", response);
  1. Sending Notifications: You can inform peers about specific tasks without expecting a result:
rpcService.notify(bobPeerId, 'subtract', [10, 3]);

Defining Computation Methods

The underlying computations are facilitated by defining methods within the service. Here's an example of an addition method:

import { RPCException } from "@organicdesign/libp2p-rpc";
import { fromString as uint8ArrayFromString, toString as uint8ArrayToString } from 'uint8arrays';

export default function add(params, peerId) {
    const strParams = JSON.parse(uint8ArrayToString(params))[0];
    const [a, b] = strParams;
    if (typeof a !== 'number' || typeof b !== 'number') {
        throw new RPCException("Parameters must be numbers", 2);
    const result = a + b;
    return uint8ArrayFromString(JSON.stringify({data: result, dataType: typeof result}));

Potential Applications

The possibilities with the Simple P2P RPC Service are vast:

Decentralized Gaming: A gaming environment where each device contributes to the overall performance and experience.

Transparent Voting Systems: A tamper-proof system where every vote is a transaction broadcasted and validated by the network.

Collaborative Digital Art Platforms: Artists worldwide can collaborate in real-time, with each contribution being updated and rendered simultaneously.

Distributed Scientific Research: Distribute computational tasks related to data analysis, simulations, or AI model training.

P2P Content Delivery Network (CDN): A decentralized CDN where website resources are shared among users, reducing load times and ensuring content availability.

Document Verification Systems: Store and verify documents across a network, ensuring authenticity and minimizing unauthorized changes.


The Simple P2P RPC Service offers a streamlined approach to decentralized computing and peer-to-peer communication. From efficient data storage to real-time collaboration, its potential applications span various industries. Whether you're exploring innovative solutions or enhancing existing systems, this framework offers a robust foundation for decentralized projects.
