Persistence Labs is the driving force behind Persistence, a specialized decentralized Layer-1 Cosmos/Tendermint blockchain focussed on building the liquid staking hub of the Proof of Stake economy.

**Persistence** facilitates the issuance and deployment of liquid staked assets through **pSTAKE**, allowing users to earn network staking rewards and participate in decentralized finance **(DeFi)** simultaneously thus enhancing capital efficiency. 

On top of the **Persistence** blockchain live decentralised applications tailor-made for liquid staked assets: a decentralised exchange, a money market, a yield optimiser, etc. All the ecosystem products are designed to help make liquid staked assets the default asset class of the **PoS** economy.

**Persistence’s Core** mainnet is a **Proof-of-Stake** chain powered by the **Tendermint BFT** consensus engine. Persistence’s multi-chain tech stack (currently supporting **Cosmos**, **Ethereum**, and other **Tendermint-based** blockchains) abstracts away the complexities for developers. It enables them to create decentralized exchanges, marketplaces, lending/borrowing platforms, and the like.

Essentially, **Persistence Labs** is building an ecosystem of multi-chain **Web3** **products** for both retail and institutional users on the **Persistence Core Blockchain**.
