Cosmos will undergo a Vega upgrade and all validation nodes and node operators will need to participate in the testing process to ensure a stable release of Vega, including delegating most voting rights to nodes controlled by the Cosmos Hub team. The update includes various version updates to secure Core components that Cosmos Hub relies on, such as Cosmos SDK, Tendermint Core and IBC, that will help avoid consensus errors and improve efficiency through features like fees and vote delegates, It will also enhance Cosmos Hub performance and ensure that future upgrades are seamless.

Terra, a Blockchain developed based on the Cosmos SDK, has officially activated the IBC standard (Inter-Blockchain Communication, Blockchain communication), Terra Ecology's users can connect to other IBC-compliant blockchain networks across the chain and send and receive assets, Blockchain networks that support the IBC standard include Cosmos Hub (ATOM), IRISnet (IRIS), Osmosis (OSMO) and Crypto.com (CRO). According to Do Kwon, co-founder of Terra Blockchain developer Terraform Labs, the activation of IBC will enable cross-chain transactions of stablecoins, protocols and native LUNA in Terra's ecosystem.

According to the Cosmos Signa series of keynote talks, the next update for Cosmos Hub, "Interchain Security", a Cosmos shared Security solution, could be launched as soon as the first quarter of 2022, Also allows Cosmos Hub pledgers to earn rewards on multiple chains. In addition, Cosmos is building a new blockchain called Sagan for testing. According to The Block, Sagan may be akin to a canary network.

Ethermint, developed by Cosmos, will be upgraded to Evmos due to trademark issues and expanded scope. Evmos will act as an EVM Hub for Cosmos, allowing smart contracts to be easily deployed and communicate within Cosmos. By the end of the year, Evmos will be delivered to the main network with full EVM compatibility in Cosmos. Specifically, Evmos will interoperate with the Ethereum main network, EVM compatible environments, and other BFT chains via IBC, making it easy for users and developers to move easily between blockchain chains.

The Cosmos Cross-chain Bridge "Gravity Bridge" was launched, allowing ERC20 assets on Ethereum to be brought into Cosmos Ecology and to interact with Cosmos Ecology's projects, as well as Cosmos assets to be brought into Ethereum, All important EVM compatible chains will also be gradually integrated in the future. Gravity Bridge is currently being audited by Informal Systems, the developer of Cosmos, and a two-week "Code4rena" is scheduled to open on April 26, inviting various participants to review the code for errors or bugs to receive rewards. Launched by Cosmic-based distributed networking solution Althea, the Gravity Bridge is a cross-chain Bridge designed for Cosmos Hub, which allows Cosmos Ecology's project to interact with ERC20 assets. Such as WETH, DAI, USDC, WBTC, etc.

Center of the universe to the Moon! Block height rises to 384,000 - the average number of kilometers separating the Earth from the moon.

Cosmos SDK codebase reviewed and enhanced, Genesis file ready, Cosmos Hub open.

Collect Genesis Trades will collect bound trades for major web authenticator candidates. A tool will be released for compiling the Cosmos Hub Genesis file based on the results of the Cosmos fundraising campaign and other community data.

Cosmos continues to build on top of the SDK. Binance, the world's largest cryptocurrency exchange, has announced the launch of Binance Chain based on the Tendermint Core and Cosmos SDK. Big Bang: Cosmos Hub launched in the first season of 2019

The software is fully functional.

Using Cosmos SDK V0.26.0, declare the code base to be a fully functional release of Cosmos Hub.

Ledger Nano S is one of the most popular hardware wallets. With this milestone, all future test nets will support the Cosmos token protected by this hardware wallet.

Validators and sponsors can now create plain text proposals and vote on them on Testnet. On the main network, a successful proposal will influence the future direction of Cosmos Hub.

Token Authorization Users can delegate tokens to validators on Testnet. You can do this through Voyager or the CLI. When the Testnet validator stops voting on new blocks, it can be drastically reduced. Drastically cut verifiers will permanently lose some bet tokens.

Validators on Testnet can receive token extension rewards on each block. Initial support for the rate of commission for examiners has also been implemented.

[Decentralized Genesis] Community-created Genesis deals are added to all upcoming Online Genesis files. This means that members of the Cosmos community can join the network starting with the Genesis block.

[Asynchronous candidate] All-node operators can asynchronously declare verifier candidates. As a top 100 validator, new blocks can be proposed.

Dynamic peer discovery full nodes and validators can dynamically update the connected peers through the PEX reactor.

Users can send and receive tokens to each other on the Cosmos Hub. Transactions can be created through Voyager or CLI.

Cosmos fundraiser completed.

Cosmos White Paper released.
