DeFi
Acala Network
Acala is building a sustainable liquidity layer for Web3 finance that automatically captures returns, aiming to become the HyFi (DeFi+CeFi) infrastructure for crypto and real-world assets. Acala's multi-chain asset center UAH (Universal Asset Hub) provides multi-chain liquidity staking (LST) protocols such as LDOT and synthetic assets tDOT (DOT-LDOT), AMM, and highly compatible and customizable EVM+ (based on Substrate). The security of the Acala network is supported by the Polkadot relay chain and is also a liquidity gateway for Polkadot parachains and L1/L2 blockchains.

storage
CESS
Cumulus Encrypted Storage System (CESS) is a high-speed, secure, scalable, smart contract-compatible decentralized cloud storage network infrastructure developed based on Substrate. It is the first decentralized distributed cloud storage network that supports large-scale enterprise-level commercial applications. It consists of a four-layer network architecture of blockchain, storage network, content distribution network and application layer. CESS uses a random rotation consensus node mechanism to coordinate network resources and loads, and ensures data integrity, security, traceability and privacy through mechanisms such as multi-copy recoverable storage proof (PoDR²), multi-type data confirmation (MDRC), and decentralized proxy re-encryption. CESS will support WASM and be compatible with EVM smart contracts to enable it to build a secure and efficient decentralized storage network for Web3 and large-scale commercial applications.
