What is Neutron

Neutron is permissionless smart contract platform for Interchain DeFi built with Cosmos SDK & Tendermint. Neutron allows to deploy smart contracts to the market in a blaze. Smart contracts can query, transact and manage accounts in remote zones directly from Neutron.

Neutron is the most secure CosmWasm platform because it uses Interchain Security technology. Interchain Security allows Neutron to have the same security as Cosmos hub (which is 200M+ ATOM tokens). This means that Cosmos hub validators will also secure Neutron, for which they will be rewarded with native tokens distributed from consumer fees.

Neutron is incubated by P2P Validator who also were founders of Lido Protocol.

Interchain Accounts(ICA)

Interchain accounts allow modules and smart contracts to execute and track transactions on foreign zones via IBC, instead private keys, and without deploying additional code. Also ICAs allow transactions to be written and transported in a way that can be executed on the host chain.

Neutron will be both a “host” and a “controller” and will launch with a custom implementation that makes Interchain Accounts available to smart contracts. It means, smart contracts on Neutron will be able to interact with modules and zones from other ICA-enabled Cosmos chains and vice versa.

Interchain Queries

A query is a way to retrieve data from a blockchain’s storage. For example, in order to find out about the balance of a certain token or tokens in a wallet, you need to send a query and get a reply with proof. Queries are widespread in the DeFi sphere and without them its existence is impossible. The problem is that queries often only work within a single blockchain, but with IBC and ICQ you can solve this problem and send queries between different blockchains connected by IBC.

How this would work:

  1. On the querying zone, the ICQ module collects query requests and makes them available to relayers;
  2. Relayers go to the queried zones, find a "value" for each "key" and package them with cryptographic proofs;
  3. Relayers bring the packaged results back to the ICQ module, which verifies them;
  4. Specific smart-contracts get the verified results from the module;
  5. They process the raw results into a neat data structure for the author of the query.

Why Neutron makes sense

The main advantages of Neutron are security and interoperability. Neutron will allow you to create applications that run on Neutron, but they will also run on all blockchains that are connected to Neutron via IBC, while having the same security as the Cosmos hub.

This will lead to significant development of DeFI in the Cosmos ecosystem, and will also make life easier for users, because they won't have to think about which network they are on now Juno, Cosmos hub or Evmos. Neutron will allow you to use the services you want to use from wherever you are in Cosmos. And then get the assets you want on whatever chain you want to get them on.

Roadmap

Neutron mainnet is scheduled for launch in the first quarter of 2023, currently undergoing Baryon Testnet.
