Massa: The Decentralized and Scaled Blockchain

Massa is a truly decentralized blockchain controlled by thousands of people. With the breakthrough multithreaded technology, we’re set for mass adoption.


Massa is a new blockchain reaching a high transaction throughput in a decentralized network. Our research is published in this technical paper. It shows that throughput of 10’000 transactions per second is reached even in a fully decentralized network with thousands of nodes.

An easy-to-read blog post introduction with videos is written here.

General documentation

A general overview of the architecture of a Massa node is given here.

Massa introduces several new features that enables new applications and adds a layer of security to your decentralized applications:

Web3 developers

If you want to build on the Massa blockchain, we recommend the following ressources:

  • Massa’s smart-contracts will get you through the various steps needed to compile and send smart-contracts to the Massa blockchain.

  • Massa’s decentralized web will show you how Massa blockchain can be used to host decentralized websites.

  • massa-web3 is a collection of useful resources for the frontend development of your decentralized application.

  • Local network generation will get you through all the steps required to launch a local Massa network.

  • Useful resources is a collection of useful resources for smart-contract development.

  • External resources is a collection of useful resources developed by external contributors.

Technical resources

Here you’ll find the documentation on the various JSON-RPC API endpoints exposed by a Massa node.


As decentralization is our core value, we would like to help you start running a Massa node on our testnet. You’ll find a full tutorial on how to install and stake with your node on our testnet here.
