Earlier last year, Cosmos completed its white paper, realizing its founding vision of blockchain interoperability, scalability, and usability as outlined in its original 2016 roadmap. Now, it’s time to develop a new roadmap. Cosmos 2.0 technical white paper will be launched in 2022. New milestone roadmap

Let us recast the light of cosmos together

This Cosmos Hub product roadmap incorporates input from product owners, key Cosmos stakeholders (ATOM holders, Interchain Foundation, and Cosmos Hub operations), internal Gaia/ATOM calls, virtual Gaia Org calls, the Cosmos Hub as a Port City (opens in new window) article, and the ATOM2021 (opens in new window) pitch deck.

The roadmap provides a one-year guideline within which stakeholders can anticipate updated features of the Cosmos Hub, with the greatest degree of specificity for the most immediate upgrades and decreasing precision available over time.

Upgrades are designed to increase features such as liquidity, economic security, usability, and participation. To highlight our focus on DeFi, we have chosen to use Greeks from Finance (opens in new window) in naming upcoming upgrades.

#Delta Upgrade (Completed July 12, 2021)

  • Gaia v5.0.x

  • Gravity DEX:

    • A Scalable AMM Model for Token Swaps

    • Driving liquidity for tokens on the Cosmos Hub

    • Providing price consistency and order execution

#Vega upgrade (completed 14 Dec 2021)

  • Gaia v6.0.x

  • Cosmos SDK v0.44

    • Cost subsidy module:

      • Allows payment on behalf of another account

    • Authorization module:

      • Provides governance functionality to execute transactions on behalf of another account

  • Liquidity Module v1.4.2

    • Gravity DEX with dependency updates

  • IBC v2.0.0

  • Tendermint v0.34.14

  • Cosmosvisor v0.1.0

  • IBC packet forwarding middleware v1.0.1

    • Cosmos Hub as a Router

  • External link launch: Gravity Bridge

    • Transfer ATOM, ETH, ERC-20, and other Cosmos tokens between Ethereum and the Gravity Bridgechain, and by extension all IBC-connected chains.

    • Fee and reward models across Cosmos and Ethereum hosting

#v7-Theta Upgrade (Completed on March 25, 2022)

  • Gaia v7.0.x

  • Cosmos SDK v0.45

    • Minimal update with small fixes

  • Gravity DEX: Liquidity v1.4.5

    • Add a circuit breaker governance proposal type to disable adding new liquidity to make migration possible.

  • International Broadcaster 3.0.0

    • Cross-chain account module

      • Allows the creation of accounts on a “host” blockchain, which are controlled by an authentication module on a “controller” blockchain.

      • Arbitrary messages can be submitted from the “controller” blockchain to the “host” blockchain for execution on behalf of cross-chain accounts.

      • Use ordered IBC channels, one per account.

#v8-Rho upgrade (expected Q1 2023)

  • Gaia v8.0.x

  • Cosmos SDK v0.45

    • Minimal update with small fixes

  • Interchain Security - Necessary participation of interchain validators

    • Cosmos shared security solution, using IBC Cross-Chain Verification (CCV) to relay validator set combinations from the provider chain (Cosmos Hub) to the consumer chain. This validator set is responsible for producing blocks on both networks using different nodes. Misbehavior on the consumer chain can lead to a significant slashing of the provider chain staked tokens (ATOM).

  • Global Fees Module

    • Allows denominations and minimum fees as governance parameters so that gas can be paid in various denominations.

    • Visible on tgrade (opens new window) Enabled in ante.go (opens new window)

#v9-Lambda upgrade (expected Q1 2023)

  • Gaia v9.0.x

  • Cosmos SDK v0.47

    • Group Module:

      • Enable higher-level multi-signature permissioning accounts, such as weight-based voting strategies

    • Government module improvements

      • Execute arbitration transactions rather than just governance proposals.

      • Enable more expressive governance modules.

    • Phasing out broadcast mode

    • Removing proposer-based rewards

    • Consensus parameter module

      • With the deprecation of the param module, this will allow governance or other accounts to modify these parameters.

    • Changes Required for Interchain Security

    • Liquid Staking Module

      • Free, secure, and low-risk delegation to other parts of the Cosmos ecosystem

      • Functions include enabling transfer of rewards and voting rights

  • International Broadcaster 5.x

    • Relay incentives so that IBC packets include a fee to cover relay costs.

  • Cross-chain account message authorization module

    • An authentication module that authorizes any account to create a cross-chain account on any IBC-connected "host" blockchain that has the Cross-Chain Account IBC module.

    • Accounts can be private key controlled users, and ultimately the Gov module and any group modules.

  • IBC Msg Whitelist skips MinFee in CheckTX

  • Bech32 prefix forwarding

    • https://github.com/osmosis-labs/bech32-ibc (opens in new window)

  • Liquidity module deprecation

    • Includes forced exit liquidity

#v10-Epsilon (expected Q2 2023)

  • Gaia v10.0.x

  • IBC Query

  • Central ATOM Liquidity (HAL)

    • Protocol Controlled Value application to acquire ATOM LP tokens with Interchain Security Tokens

#v11-Gamma (expected Q3 2023)

  • Gaia v11.0.x

  • Interchain Security v2 - Layered Security

    • Consumer chains combine their own set of staked token validators with the supplier chain validator set.

#Future considerations

The Cosmos Hub is a decentralized network with many different contributors. As such, there is no single authority on what is or may be part of the Cosmos Network. The Cosmos Hub team at Interchain does their best to maintain the Gaia repository, which is the main codebase that runs the Cosmos Network. The Interchain Foundation is one source of funding for engineering work that may go into the Cosmos Hub. We do our best to participate in an ongoing conversation about the mission, vision, and purpose of the Cosmos Hub so that we can best support the work to achieve it through funding, engineering, coordination, and communication. Here is a list of some topics that have been discussed by contributors inside and outside of Interchain, although not yet developed to the point of inclusion in the roadmap:

  • Multi-hop routing

    • Simplify the relayer topology so that packets from inter-chain pairwise channels can be routed through the hub while preserving the original channels and more importantly the token naming path.

  • Chain name service

    • Chain ID Registration

    • Node Registry

    • IBC Path Analysis

    • Asset Registration

    • Account Registration

    • Bech32 Registry

  • IBC Non-Fungible Tokens

  • NFT Module

    • Enables simple management of NFT identifiers, their owners, and related data such as URIs, content, and provenance

    • Extensible base modules for expansion, including collections, custody, provenance, and marketplace

    • Unless the Cosmos Hub plans to be a full platform for NFT issuance, it should pair content that includes this module with the IBC NFT module, similar to how the Cosmos Hub does not allow the issuance of new fungible tokens but allows them to be transferred via IBC.

  • privacy

  • Smart Contracts

  • Summary

The Cosmos Hub Roadmap is maintained as a living document by the Interchain Cosmos Hub Team and updated in collaboration with key stakeholders from the multi-entity Cosmos community.
