RHINO is an enterprise blockchain infrastructure and services organization built on over 60 years of combined infrastructure, security, and program delivery experience.

Launched in 2020, the RHINO team operates validator and RPC infrastructure across 60+ blockchain networks, serving over 30 billion RPC requests monthly through our global infrastructure. We have been part of a multitude of genesis ceremonies, contributed to the success of blockchain projects, and have been instrumental during testnet, launches, upgrades, and chain "incident" management.

Our strengths include delivering secure, redundant and geo-distributed infrastructure at-scale for institutional investors, web3 project teams, venture capital, as well as for our own staking operations. We maintain load-balanced clusters across the US, Europe, East Asia, and Southeast Asia with enterprise SLA commitments of 99.9% to 99.99% uptime.

We like to get involved in projects "early", offering a high amount of engagement, tooling, analytics, automation and needed assistance for new L1s. We're clear communicators, with experience working with geo-distributed diverse validator teams and assist in the coordination, communication and documentation of efforts for efficient and performant testnets and mainnet launches.

Today we run operations for many different types of projects:

• RHINO is a selected "genesis" node operator for Aptos, including the responsibility of managing the staking pool validator operations for Aptos Labs Corporation. We provide the Aptos ecosystem's largest global API service at aptos-apis.com.
• RHINO is a Chainlink node operator providing Decentralized Data Feeds, Proof of Reserve, and VRF across multiple ecosystems. We also operate as a Chainlink Cross-Chain Interoperability Protocol (CCIP) node operator, providing transaction verification across all CCIP participating networks with global redundancy.
• RHINO is one of 8 designated proposers for dYdX, the leading decentralized derivatives protocol, and leads the chain in signing performance.
• We run validators and infrastructure across many networks including Sei, Berachain, Monad, Nillion, Seda, Stargaze, XRPL EVM Sidechain, and more. We were genesis validators for each of these networks.
• We provide IBC relaying services for cross-chain connectivity, including supporting routes for Cosmos Hub, Babylon, Noble, Sei, Osmosis, KiiChain and other IBC-enabled chains.
• In 2021, we helped Helium transition from a decentralized hotspot model to a dedicated validator set, running multiple validators and analytics infrastructure for the network during that critical phase.
• We operate some of the largest RPC, API, and IPFS arrays in web3. For both public and private clients, the RHINO team manages dozens of nodes that provide the infrastructure backbone for Sei, Berachain, Aptos, and more. Currently our nodes handle over 30 billion RPC requests/month globally.

Although a small team, we utilize our deep experiences in security, network operations, infrastructure, and automation to deliver operations "at-scale" — working to reduce downtime, increase delegator rewards, and ultimately deliver better and more secure experiences to project teams and end-users.

RHINO utilizes a mix of RHINO-owned and cloud based infrastructure to deliver highly-available, redundant infrastructure for blockchain projects across ecosystems.

The following diagram outlines the high-level approach:

Notable points and benefits to this redundant DC-based architecture:

• Within our RHINO owned data centers, all servers and network infrastructure have a minimum of n+1 redundancy across power supplies, power delivery, and battery backup.
• Network infrastructure includes dual 10Gb attach for all servers, and Virtual Routing and Forwarding (VRF) separation providing secure segmentation between management systems and per-customer chain infrastructure.
• Hypervisor virtualization is provided by VMWare, with node clustering and vMotion capabilities to distributed workloads for optimum performance as well as seamless maintenance.
• Additional use of bare metal servers allow for on-metal compute & direct disk access where necessary.
• Secure, high bandwidth, encrypted connectivity is in place between data center networks and public nodes to allow for node relocation, data duplication, and encrypted communication across sites.
• High availability firewalls provide secure, least privileged access and connectivity between systems, with 100% of all connections logged to a cloud monitoring system.
• Overlay networking with signed certificates and granular group controls eliminates traditional VPN vulnerabilities while providing fine-grained access control and complete visibility across our global infrastructure.
• Netflow data is generated for all network traffic, and is sent to a flow analytics system for threat detection.
• All traffic is subject to Snort based Intrusion Detection and Prevention.
• Wazuh provides comprehensive security monitoring including file integrity monitoring, CVE detection, and real-time intrusion detection across all systems.
• Secure, out of band, multi-factor based remote management is in place for 24x7 monitoring and support by RHINO team.
• Horcrux based RAFT signing infrastructure exists in both RHINO owned racks with the 3rd node running in a geo-local region (where applicable).
• On-premises and cloud-based monitoring and alerting systems are employed to monitor network, security and server hardware, hypervisor workload performance, security analytics, intrusion detection, chain-metrics, signing performance, as well as event logging from all networking, server, and security infrastructure.
• 24x7 event escalation and alarm notification provided by PagerDuty.

Our infrastructure and operations are aligned with ISO 27001 standards, with full certification expected in H1 2026.

We also try to contribute to each ecosystem we're in, through the production of tools and best practices valuable to node operators, partners and project teams.

• Open source tooling for validators/node runners:
  • Monitor Your Aptos validator and validator fullnodes with Prometheus and Grafana
  • Ansible playbook for Aptos Node Management (Bare Metal)
  • Ansible playbook for Berachain Node Management (Bare Metal)
  • Ansible playbook for Secure Server Setup, including server setup, Cosmos/tendermint chains, Aptos, Chainlink, horcrux, and more
• We provide public RPC, API, gRPC endpoints, and seed nodes for devnet, testnet and mainnet blockchains.

Finally, be sure to catch members of the RHINO team on Game of Nodes! We broadcast live on YouTube and Twitter every Wednesday at 21:00 UTC.

Game of Nodes is weekly long-form podcast featuring independent validator teams discussing tech, governance, drama, and airdrops across Ethereum, Cosmos, Aptos, and everywhere else. Holistically wholesome since 2022.
