About Arc blockchain
Arc is an open Layer-1 blockchain built by Circle, the issuer of USDC, purpose-built for stablecoin-native finance. Positioned as an "Economic Operating System" for the internet, Arc is designed to bring institutional financial activity on-chain: payments, FX, lending, capital markets, and tokenized assets.
Arc uses USDC as its native gas token for predictable, dollar-denominated fees, while ARC (the network's native coordination token) for staking, governance, and fee capture. Arc's public testnet launched in October 2025, with mainnet beta expected in 2026.
What is the Arc Validator
Validators are the operators that secure the Arc network, proposing and confirming blocks and processing transactions with deterministic, sub-second finality. Arc's consensus engine, Malachite, is a BFT protocol, which maintains network integrity even if up to a third of validators fail or act maliciously.
In practice validators are expected to meet audited security standards, run across multiple regions, and commit to defined uptime requirements. Circle has published a roadmap toward broader participation through a future transition to a permissioned Proof-of-Stake model, coordinated by a native ARC token.
How it works
Arc currently uses a permissioned Proof-of-Authority (PoA) model: validators are known, vetted, and selected on operational resilience and regulatory compliance.
Running a validator to the Arc's institutional market standards is a continuous operational commitment: 24/7 monitoring, incident response, secure key management, and ongoing maintenance.
Hence, network participation is typically handled by dedicated infrastructure operators, like Everstake.
Everstake's white-label solution is built to meet these standards, ready to operate a dedicated validator under your brand.
Why Everstake
Everstake's white-label solution is engineered to support the institutional standards Arc demands:
- Multi-region active-passive failover
- Continuous monitoring and incident response
- 99.98% observed historical uptime
- SOC 2 Type II attestation and ISO/IEC 27001:2022 certification
- Independent assessment of controls mapped to DORA requirements
- Proven operational rigor in running infrastructure
- Institutional-grade reporting
We are ready to operate dedicated, enterprise-grade validators under your brand, so you gain network participation without building and maintaining an ops team.
