A cryptocurrency with a tiny portable blockchain.

Coda swaps the traditional blockchain for a tiny cryptographic proof, enabling a cryptocurrency as accessible as any other app or website. This makes it dramatically easier to develop user friendly crypto apps that run natively in the browser, and enables more inclusive, sustainable consensus.

Build global cryptocurrency apps with Coda

Coda icon on a phone, connected to devices all around the world.
<script src="coda_api.js"></script>
<script>
  onClick(button)
    .then(() => Coda.requestWallet())
    .then((wallet) =>
        wallet.sendTransaction(...))
</script>

Build apps and games that take advantage of the new capabilities enabled by cryptocurrency with just a script tag and a few lines of javascript.

Your users will have a seamless, secure experience without having to download any extensions or trust additional 3rd parties.

Inclusive consensus

Coda
Other Blockchains

Simple, fair consensus designed so you can participate. Participation is proportional to how much stake you have in the protocol with no lockups, no forced delegation, and low bandwidth requirements.

With just a small stake you'll be able to participate directly in consensus.

Sustainable scalability

Calculations assume 1M accounts and growing with an increasing rate of transactions
Calculations use typical transaction costs for consensus and adding transactions to the protocol databse For Coda: energy use required by Coda for consensus plus snarking transactions for a year at 100tps For PoW: energy use required for mining by a successful PoW cryptocurrency for a year (numbers taken from bitcoin)

With Coda's constant sized blockchain and energy efficient consensus, Coda will be sustainable even as it scales to thousands of transactions per second, millions of users, and years of transactions history.

Help compress Coda by participating in snarking. Just like mining, with snarking anyone can contribute their compute to the network to help compress the blockchain.
