Gno

At first, there was Bitcoin, out of entropy soup of the greater All. Then, there was Ethereum, which was created in the likeness of Bitcoin, but made Turing complete.

Among these were Tendermint and Cosmos to engineer robust PoS and IBC. Then came Gno upon Cosmos and there spring forth Gnoland, simulated by the Gnomes of the Greater Resistance.

Gno is an interpreted and fully-deterministic implementation of the Go programming language, designed to build succinct and composable smart contracts. The first blockchain to use it is Gno.land, a Proof of Contribution-based chain, backed by a variation of the Tendermint consensus engine.

Getting started

If you haven't already, take a moment to check out our website.

The website is a deployment of our gnoweb frontend; you can use it to check out some example contracts.

Use the [source] button in the header to inspect the program's source; use the [help] button to view how you can use gnokey to interact with the chain from your command line.

If you have already played around with the website, use our Getting Started guide to learn how to write and deploy your first smart contract. No local set-up required!

Once you're done, learn how to set up your local environment with the quickstart guide and the contributing guide.

You can find out more existing tools & documentation for Gno on our awesome-gno repository. We look forward to seeing your first PR!
