Overview of Fairblock

Open finance cannot scale if every payment, trade, and treasury move is exposed onchain. Fairblock ships end-to-end applications that eliminate information leakage, enable fair price discovery, and unlock new use cases for retail, institutions, and businesses.

Fairblock is a dynamic, decentralized cryptographic computer with its own execution layer purpose-built for confidential computing. Confidentinal apps (cApps) run on Fairblock's native chain, FairyRing, and are accessible from major ecosystems so users can seamlessly use them without bridging any funds or switching wallets.

Why Fairblock​

  • Product-first: cApps run on FairyRing for performance and security, then are made accessible from other ecosystems to meet users where they are. Distribution flows into Fairblock cApps.

  • Multimodal cryptography: Dynamic confidentiality selects the right cryptographic schemes per use case (HE, IBE, MPC, lightweight ZK, etc.) to maximize performance and security without unnecessary overhead.

  • Private by default. Verifiable on demand: Sensitive values are encrypted by default. Authorized parties can receive selective, per-transaction access when required (audit, AML, disputes). No blanket surveillance of the entire transaction history. Designed for regulated flow and compatible with post-execution selective disclosure (OFAC, FinCEN, MiCA friendly)

  • Onchain verification, not black boxes: Correctness and validity are verified onchain. Single-TEE or opaque off-chain coprocessor/relayer designs are intentionally avoided to minimize trust assumptions and security risks.

  • Performance for everyday payments and DeFi: The lightest scheme that meets requirements is chosen to avoid one-size-fits-all overkill approaches. This results in no multi-minute proofs on the client side and low computation fees.

What We Ship​

Stabletrust: Confidential Stablecoins​

Send and receive stablecoins with encrypted amounts and balances on public chains. Addresses remain transparent for DeFi composability and traceability. A specific transaction, and only that transaction, can be disclosed when required. It’s not a mixer or an isolated privacy chain. Built for: payroll & payouts, cross-border commerce, trading, treasury operations, OTC, M&A, and strategic buybacks.

Protected Trading: Confidential Execution​

Eliminate information leakage and manipulation while interacting with other users on a blockchain. Encrypted orders, intents, and bids with conditional decryption enable better price discovery in trading, lending, intents, and token launches, all without reliance on centralized intermediaries.

Where Users Access Fairblock cApps​

Fairblock cApps run on FairyRing and are accessible from ecosystems where liquidity lives. This allows users to keep their wallets and workflows while gaining confidentiality.

  • EVM: Ethereum, Arbitrum, Hyperliquid, Base, Noble AppLayer, and more
  • Solana
  • Payment networks (e.g. Plasma, Noble, Tempo, Arc, etc.)
  • Trading platforms (e.g. CowSwap, Uniswap, etc.)

Distribution is user-led. Ecosystems integrate into Fairblock cApps.
