Substrate Ecosystem Newsletter — June Issue

Substrate Monthly — Ecosystem Technical Newsletter, produced by OneBlock+, compiles and organizes technical progress across the Substrate ecosystem. Each issue highlights key product updates, code commits, releases, community discussions, technical documentation, and ecosystem growth — making it easier for you to stay on top of what’s happening in the Substrate world.

The following is the June edition. Enjoy the read!

DeFi

Acala Network

Acala is building an automated yield-capturing sustainable liquidity layer for Web3 finance, aiming to become the HyFi (DeFi+CeFi) infrastructure for crypto and real-world assets. Acala’s multi-chain asset hub UAH (Universal Asset Hub) provides multi-chain liquid staking (LST) protocols, such as LDOT with synthetic assets tDOT (DOT — LDOT), AMM, and highly compatible and customizable EVM+ (based on Substrate). The Acala network’s security is supported by the Polkadot relay chain and serves as 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 supporting large-scale enterprise-level commercial applications. It consists of a four-layer network architecture: blockchain, storage network, content distribution network, and application layer. CESS adopts a random selection rotating consensus node mechanism to coordinate network resources and load, and ensures data integrity, security, traceability, and privacy through mechanisms such as multi-replica recoverable storage proof (PoDR²), multi-type data rights confirmation (MDRC), and decentralized proxy re-encryption. CESS will support WASM and be compatible with EVM smart contracts to build secure and efficient decentralized storage networks for Web3 and large commercial applications.

CESS’s mission is to provide practical storage services for Web3, creating a new generation of object storage services (DeOSS). Currently, CESS network’s product ecosystem is gradually enriching and prospering, having incubated innovative applications such as online file sharing tools (DeShare), public chain snapshot storage services, and CESS cloud drive. Everyone is welcome to experience them. The following is this month’s progress:
