SoLad: Solana’s Storage Lad

Tagline: Storing Solana logs and data securely under flexible conditions

Overview

SoLad is a peer-to-peer storage network for Solana, tackling transient log pruning (RPCs clear logs in days) and centralized explorer risks (e.g., Solscan). It supports Event streams data lake, off-chain assets (e.g., NFT metadata), and Layer 2 data at $6/GB for 20 years. It uses 1-10 shards, each with 3 nodes, for redundancy and speed (~10MB/s).

• Client: Uploads data to one shard ($6/GB/20 years).
• Payment: $6/GB (0.03 SOL/GB at $200/SOL), 25% treasury ($1.50/GB), 75% nodes ($4.50/GB).
• Nodes: Store shards redundantly, earn $0.15/100MB/node (8.7% margin).
• Use Case: 10,000 dApps, ~275GB/year/dApp (2025 estimate).

Features

• One-Time Flexible Fee: eg. $6/GB locks data for 20 years.
• Sharding: 1-10 shards, 3 nodes each, client-split (e.g., 100MB/shard for 1GB).
• Proof of Storage (PoS): Nodes prove data in <100ms, claim rewards over 2,920 epochs (~2.5 days).
• Solana L1: Payments and rewards via Anchor program.
• Demo: 10MB upload, 1 shards, 0.00029 SOL, query in 100ms.

How To Use

• Clone repo; git clone https://github.com/cenwadike/solad
• Go to the section you want to use and check out the README and examples

How To Run Locally

Requirements

• Solana CLI
• Solana Local Validator
• Anchor v0.30.1
• npm v10.8.2
• node v20.19.1
• rustup 1.28.1
• rustc 1.85.1
• cargo v1.85.1

Setup Contract .env

  NODE_PRIVATE_KEY=

Setup Node .env

  NODE_SOLANA_PRIVKEY=
  WS_URL=ws://127.0.0.1:8900
  HTTP_URL=http://127.0.0.1:8899

Setup frontend .env

  VITE_SOLANA_PROGRAM_ID=4Fbo2dQdqrVhxLBbZrxVEbDBxp8GmNa9voEN96d4fQJp
  VITE_SOLANA_RPC_URL=http://127.0.0.1:8899
  VITE_NODE_API_URL=http://127.0.0.1:8080

NODE_SOLANA_PRIVKEY and NODE_PRIVATE_KEY must match for a smooth local test

Run Solana local validator

  solana-test-validator -r

Run the onchain program initialization

  anchor test --skip-local-validator

Run one SoLad Node

  cargo run

Run the frontend

  npm i

  npm run dev

PS:

• NODE must stake more than 0.1 Sol (adjustable)
• Wallet connected to the frontend must have enough Sol to cover gas and storage payment

SDKs

• SoLad provides Rust and TypeScript SDKs for interacting with the node and the smart contract
