Helping Secure Chainlink Across 54+ Blockchains

RHINO has been a Chainlink node operator since 2021. Today we run Cross-Chain Interoperability Protocol (CCIP) nodes on 54+ blockchains, alongside Off-Chain Reporting (OCR) for Chainlink Data Feeds. Chainlink is our largest partnership.

Our Role in the Network

Chainlink is the industry-standard oracle platform bringing the capital markets onchain, and it powers the majority of decentralized finance. Its Cross-Chain Interoperability Protocol (CCIP) moves tokens and data between blockchains. In CCIP 2.0, no transfer executes until the Chainlink Committee Verifier, a group of 16 independent, security-reviewed node operators, reaches consensus on it and signs it. RHINO is one of the 16, on 54+ blockchains.

How a Chainlink CCIP 2.0 transfer works: a sender on the source chain submits tokens or data to the CCIP Router. The Chainlink Committee Verifier, 16 independent node operators including RHINO, reaches consensus and signs the transaction, alongside any optional Cross-Chain Verifiers. The Executor then submits the verified message to the CCIP Router on the destination chain, which delivers it to the receiver.

What We Operate

CCIP 2.0

Node infrastructure for the Cross-Chain Interoperability Protocol, Chainlink's standard for cross-chain messaging and token transfers.

Off-Chain Reporting (OCR)

Signing and aggregating market data for Chainlink Data Feeds used by DeFi protocols and financial institutions.

How We Run It

The same operational discipline behind our validator and RPC services, applied to every Chainlink node.

Our own nodes on every chain

Every Chainlink node we operate reads from blockchain nodes and RPC services we run ourselves, with no dependence on third-party providers.

RHINO-operated data centers

Our Chainlink infrastructure runs out of RHINO-operated data centers, giving us direct control over security, hardware, networking, and redundancy.

Signing infrastructure built for high-value systems

Keys are held in an encrypted vault that requires hardware security keys for access, on systems hardened to CIS benchmarks and aligned with ISO 27001.

Upgrades handled ahead of time

We track network upgrades and Chainlink releases, open a ticket for each change, and coordinate upgrades so the services we support stay online.

Engineers on call 24/7

Wazuh, Zabbix, and Graylog monitoring with PagerDuty escalation, so incidents get a response within an hour, day or night.

ISO 27001 · In progress

Security and Compliance

Oracle and cross-chain infrastructure secures real value, and we run it accordingly. Our ISO 27001 certification is in progress, our controls already align with the standard, and enterprise clients can request a security assessment. Details on our signing architecture are in our FAQ.
