## dYdX Chain

The dYdX Chain is a proof-of-stake blockchain network built using the Cosmos SDK and leveraging CometBFT for consensus. The software was [fully audited](https://github.com/dydxprotocol/v4-chain/tree/main/audits) by Informal Systems and [open-sourced](https://dydx.exchange/blog/dydx-chain-official-release) by dYdX Trading Inc. ("dYdX Trading").

The [dYdX Chain open-source software](https://dydx.exchange/blog/dydx-chain-official-release) was deployed and the first block of the dYdX Chain was created by the dYdX Chain validators on October 26, 2023, at 17:00 UTC.

The dYdX community [voted](https://www.mintscan.io/dydx/proposals/173) in favor of the dYdX Unlimited upgrade on November 9, 2024.

## DYDX Token

DYDX is the dYdX Chain's Layer 1 token, as adopted by the dYdX community, through dYdX governance ([Snapshot](https://snapshot.org/#/dydxgov.eth/proposal/0x17026e18317dc29fe745d3130246a83b1485612da9c97e7261e8f659cf33663c) and [on-chain](https://dydx.community/dashboard/proposal/15)).

DYDX, the dYdX Chain's L1 token, serves three key purposes: Staking, Security, and Governance.

1. Staking: DYDX holders have the option to serve as validators (and self-delegate) or to delegate their stake to existing validators. Such delegation increases the likelihood of the chosen validators entering or staying in the active validator set, thereby becoming a participant in the network’s consensus process.
2. Security: Staking DYDX directly contributes to dYdX Chain security. As more DYDX holders choose to stake their tokens across a diverse range of validators in the network and the total amount of stake on the network increases, it becomes increasingly difficult for a coordinated attack to influence a consensus decision.
3. Governance: DYDX empowers DYDX holders to propose and vote on proposals, directly influencing the evolution of the dYdX Chain through a democratic process. The subject matter of proposals can vary from changing a governable parameter on the dYdX Chain, spending dYdX community funds, and updating the software that dYdX Chain nodes are running, among other things.
