Juno - Interoperable Smart Contract Network

Origin Story

Juno originates & evolves from a community driven initiative, prompted by dozens of developers, validators & delegators in the Cosmos ecosystem. The shared vision is to preserve the neutrality, performance & reliability of the Cosmos Hub and offload smart contract deployment to a dedicated sister Hub.
Some of the founding principles centre around:
⚪️ Inception of the worlds first permission-less, designated interoperable smart contract network.
⚪️ Pioneering CosmWasm development and adoption.
⚪️ Eliminating common smart contract L1 bottlenecks (poor scalability, non-interoperability, high fees, concentrated governance control).
⚪️ Sister Hub to the Cosmos Hub - Preserving the neutrality of the Hub by offloading smart contract usage/congestion to a designated contract zone.
⚪️ Governance by ATOM stakers which become JUNO stakers. Stakedrop where 47% of the genesis supply goes to ATOM stakers on a 1:1 basis.
⚪️ Eliminating potential legal limitations (Juno has not/will not conduct any form of seed sale, private sale or public sale. All $JUNO entered circulation via the decentralized network launch on October 1st 2021)

What is Juno?

Junø is an open source platform for interoperable smart contracts which automatically executes, controls or documents a procedure of relevant events and actions according to the terms of such contract or agreement to be valid & usable across multiple sovereign networks.

Why Juno?

Juno as a sovereign public blockchain in the Cosmos ecosystem, aims to provide an environment for the deployment of interoperable smart contracts. The network serves as a decentralized, permissionless & censorship resistant avenue for developers to efficiently and securely launch smart contracts using proven frameworks and compile them in various languages Rust & Go.
Battle tested contract modules such as CosmWasm, allow for decentralized applications (dapps) to be compiled on robust and secure multi-chain smart contracts. Additional specialized modules may be introduced at any time via on-chain governance.

Inter Blockchain Communication (IBC)

At the heart of Cosmos ecosystem is the Inter Blockchain Communication Protocol (IBC), which sets the table for an interoperable base layer 0 to now be used to transfer data packets across thousands of independent networks supporting IBC. Naturally, the next evolutionary milestone is to enable cross-network smart contracts. This enables Juno smart contracts to interoperate with all IBC enabled networks, regardless of wasm support on external networks.

Cosmos SDK

The Juno blockchain is built using the Cosmos SDK framework. A generalized framework that simplifies the process of building secure blockchain applications on top of Tendermint BFT. It is based on two major principles: Modularity & capabilities-based security.


Agreement on the network is reached via Tendermint BFT consensus.
Tendermint BFT is a solution that packages the networking and consensus layers of a blockchain into a generic engine, allowing developers to focus on application development as opposed to the complex underlying protocol. As a result, Tendermint saves hundreds of hours of development time.


Juno is the neutral home of CosmWasm smart contracts and the InterWasm DAO. The Juno Network ecosystem is pioneering CosmWasm development and adoption.
