Introduction

Meet the dcipher network — a programmable trust layer powering the next wave of coordination in web3. Built as a permissionless threshold signing network, dcipher acts as a universal decision fabric for verifying shared intent across chains, agents, and ecosystems.

Whether you're building fair randomness into games, coordinating multi-sig actions across DAOs, or securing AI-driven agents with threshold cryptography, dcipher delivers cryptographic guarantees without central points of failure. Highly modular and chain-agnostic, it's designed to plug into any protocol, platform, or system that needs verifiable, decentralized logic.

This is foundational infrastructure for a more autonomous and accountable internet.

Randamu is the research lab that maintains and develops dcipher network. The lab provides the tools, libraries, and documentation that empower developers to use dcipher’s capabilities both on-chain and off-chain. Our mission is to equip developers with building blocks for fair, accountable, and verifiable decision-making. The Randamu team also maintains the drand protocol for randomness and the League of Entropy.

dcipher Network​

Overview​

dcipher is a permissionless threshold signing network that uses threshold cryptography to enable custom signing workflows: set your conditions, define your actions, and configure the committee you want to use — all without relying on a central authority.

Network Capabilities​

The network’s core primitives include:

  • Verifiable Randomness – Fetch publicly verifiable randomness tailored for blockchain specs. Read more here.
  • Conditional Encryption – Encrypt data that can only be decrypted after a given condition is met, be that real-world data input or a specific on-chain event (e.g, block height reached, token transfer completed), even across chains. Read more here.
  • Conditional Signing – Generalized signing based on custom workflow logic, on-chain events or off-chain data (e.g. oracles), enabling automation and trustless coordination.
  • Computational Consensus – Run WASM/JS-based off-chain computations and attest to their results on-chain.
  • Re-encryption – Transform encrypted content so it can be read by a different user, without ever seeing the original data.
  • Dynamic Committee Formation – Advanced distributed key generation (DKG) and committee tooling to form committees sharing keys and signing as a group to fulfill common management functions.

Use Cases​

These aren’t just use cases — they’re frontiers. dcipher is pioneering custom infra in the following domains that unlock entirely new design spaces:

  • Verifiable Randomness – Extend the work of drand and AnyRand by making randomness accessible to all, not just through centralized collectives like the League of Entropy. Users can spin up their own custom committees for randomness, slashing fees and tailoring trust assumptions to their specific use case.
  • Distributed Validator Technology – As Ethereum and other ecosystems transition toward distributed validator clusters (DVT), dcipher facilitates the coordination of validator responsibilities through threshold signing. This model combines strong resilience with restaking mechanisms (via platforms like Eigenlayer) to reduce computational waste and enhance network validation efficiency and security.
  • Sealed Bid Auctions for Oracle Data – Rely on committees to run sealed bid auctions for Oracle data independently of the Oracle provider. This prevents Oracle extractable value (OEV) and increases fairness in access to premium data feeds.
  • Timelock-Encrypted Mempool for MEV Prevention – Deploy encrypted mempools on L2s using Dcipher’s timelock encryption. This prevents MEV attacks by hiding transaction details until a future block height is reached, at which point the transaction is executed. If successful, this model could eventually extend to the Ethereum mainnet.
  • On-Chain Access Control – Enable decentralized subscription services and access-gated content. Users can manage access with privacy and composability across chains, overcoming the limitations of current Web3 access patterns.
  • Seamless Cross-Chain Delivery – Use threshold signatures and programmable routing to deliver cost-efficient payloads across chains without relying on monolithic bridges or custodial relayers. This enables developers to compose logic that travels with guarantees, opening up new patterns for settlement, messaging, and shared state between ecosystems.
  • Decentralized Gaming Infrastructure – Power fair matchmaking, randomized game mechanics, and loot distribution through verifiable randomness. Randamu’s tools provide better trust assumptions (depending on your threat model) and empower developers to build fully on-chain or hybrid games with high integrity.

These areas represent dcipher’s most high-leverage use cases — and we’re building the tools to make them production-ready. If you’re a developer with ideas for new applications, we invite you to explore, prototype, and contribute to the growing dcipher ecosystem.
