Etherlink is a Tezos EVM-compatible L2 that brings Ethereum compatibility to the Tezos ecosystem. Learn more about Etherlink's latest upgrade, Ebisu, which introduces Instant confirmations features.

What It Is

Proof of Speed is an interactive typing test that challenges players to type faster than Etherlink's Instant confirmations speed. As you type, green blocks appear on screen at the same pace as Etherlink's Instant confirmations (200ms per letter), creating a visual representation of how fast Instant confirmations are being created on the network.

Etherlink's new Instant confirmations feature gives developers super-fast confirmation — around 10–20 milliseconds — so they instantly know their transaction will make it into the next block.

It's different from Base's Flashblocks because Etherlink uses a first-come, first-serve system, not a gas auction.

It's like being told "you're next in line" at lightning speed — no bidding, no waiting.

Why It Matters

• Developers (especially DeFi and bot builders) get instant feedback that their transaction is locked in.
• Enables faster decision loops for trading, arbitrage, and oracle updates.
• Shows Etherlink's technical maturity and UX focus, not just raw block time.

Game Mechanics

• Race the Pacer: Type the full text before the green blocks are completely formed.
• Accuracy is Key: Your Final Score is (LPS × Accuracy). Sloppy typing won't win.
• Get a Rank: Your rank is based on your typing speed and accuracy. Faster and more accurate typing = better blockchain rank!

Ranks

Your typing speed determines which blockchain you match:

• Etherlink/Base/Unichain: 150-200ms / letter (Lightning fast!)
• Solana: 201-400ms / letter (Super fast!)
• ETH Layer2s: 401-1000ms / letter (Fast!)
• Polygon: 1001-2000ms / letter (Quick!)
• Ethereum Mainnet: 2001-12000ms / letter (Standard speed)
• Bitcoin: > 12000ms / letter (Slow and steady)

Getting Started

Prerequisites

Before running the project, you need to set up Supabase environment variables:

1. Create a .env.local file in the project root directory
2. Add your Supabase credentials:

NEXT_PUBLIC_SUPABASE_URL=your_project_url_here
NEXT_PUBLIC_SUPABASE_ANON_KEY=your_anon_key_here

⚠️ Important: Never commit .env.local to git! It's already in .gitignore.

Running the Development Server

Once your environment variables are set up, run the development server:

npm run dev
# or
yarn dev
# or
pnpm dev
# or
bun dev

Open http://localhost:3000 with your browser to see the result.
