Valid Blockchain — accessible TPI consensus

Overview

Valid Blockchain is a lightweight blockchain designed to run on modest hardware in developing regions. Unlike traditional blockchains that require expensive infrastructure or large token holdings to participate, Valid runs on as little as a few MB of RAM.

The network uses merit-based validator selection rather than wealth-based staking. Validators earn rewards through reliable uptime and honest participation, not by holding large amounts of tokens. This creates a system where anyone with basic hardware and internet access can contribute to network security.

With 10-second blocks and sub-second finality through Three-Party Integrity (TPI) consensus, Valid delivers fast transaction confirmation without sacrificing decentralization or accessibility.

Core Features

TPI Consensus

Three validators verify each block. Merit-based selection. No stake required.

Fair Tokenomics

33M VLid over 21 years. Block rewards mint as work is proven. No pre-mine.

Accessible

Uses only a few MB of RAM, so it runs on modest hardware anywhere.

Fast Finality

10-second blocks. Sub-second finality. Instant confirmation.

How it Works

Valid uses Three-Party Integrity (TPI) consensus. For each block, three validators are selected based on merit to verify transactions and broadcast the result. If all three agree, the block is finalized instantly. If two agree, the majority wins. If consensus fails, a backup validator (the "racer") steps in.

All blockchain state lives in memory using Rust's efficient Maps and HashMaps, so there are no external databases or bloated storage requirements. Every 6 hours, a snapshot is archived to ensure persistence without sacrificing performance.

Validators earn block rewards (0.0808 VLid per block in Epoch 0) plus transaction fees. Rewards decrease over three 7-year epochs (60%/30%/10% distribution), ensuring a predictable 21-year emission schedule with no sudden inflation.

The network prioritizes high-fee transactions while maintaining fairness. Anti-frontrunning protections use the parent block hash as a deterministic seed to prevent manipulation.

The Mission

Most blockchains optimize for Silicon Valley. Valid optimizes for everywhere else.

The blockchain industry has created barriers that exclude billions of people: expensive validator hardware, large minimum stakes, high-bandwidth requirements, and complex technical knowledge. Valid removes these barriers.

Global Accessibility: a few MB of RAM means validators can run on hardware affordable in any economy
Merit Over Wealth: Validator selection based on uptime and reliability, not token holdings
Community Sovereignty: No venture capital, no foundation, no pre-mine, just open-source code
Honest Economics: 33M VLid minted over 21 years through proven validation, 0.1% genesis allocation for testnet contributors
Real Decentralization: Designed for thousands of validators, not a handful of whales

Into the Future

Valid is a Layer 1 foundation designed to support specialized Layer 2 networks:

VNS (Valid Name Service): Decentralized domain registry running on 16GB validators
VIPFS (Valid InterPlanetary File System): Content distribution with efficient routing
KEVIN (Distributed AI Inference): GPU-powered compute network for AI workloads

The testnet launches soon with 33,000 VLid allocated for early validators and community contributors. Mainnet follows once the network proves stable under real-world conditions.

This isn't about competing with Ethereum or Solana on enterprise features. This is about building infrastructure that works for the 90% of the world they've ignored.
