Recap Video Roundtable - 5 Core Features That Define Arc’s DNA 🧑‍💻 As stablecoins are becoming the “payment rails” of the digital economy, a crucial question emerges: Which blockchain is fast enough, secure enough, and compliant enough to serve real-world financial institutions? 👉Last week, the @arc team (a Layer-1 built by Circle specifically for institutional stablecoins) released a 4-minute roundtable video not a flashy demo, just three engineers and researchers chatting over coffee by a glass window, yet the content feels like the blueprint of programmable money’s future. 🧑‍💻 The video I’m about to summarize includes three main speakers: - @Soghoian: Principal Software Engineer - @AdiSeredinschi: Principal Product Manager - @gordonliao: Head of Research During the conversation, they broke down five core design features that define @arc no marketing, no buzzwords, just real operational architecture. 🧑‍💻 Let’s dive in 👇 1/ Deterministic Sub-second Finality (Finality under 1 second, 100% deterministic) - Malachite BFT from Informal Systems → ~350ms average finality - No probabilistic finality, no reorgs - No waiting like Ethereum (12s) or L2s (2–7s) 👉 Built for institutional payments, FX, tokenized securities where every millisecond equals money. 2/ Stablecoins as Native Gas (Using USDC to pay gas) - Gas fees calculated directly in USD, not dependent on volatile tokens - Enterprises can forecast costs like an Excel line item Gordon Liao: “Gas fees are now more stable than the price of my morning coffee” 👉 Easier enterprise onboarding, clearer accounting. 3/ Opt-in Configurable Privacy (Privacy toggled as needed) - Hide transaction amounts & balances while addresses remain public - Uses TEE + EVM precompiles, ZK coming later - Regulators/Auditors get view-keys with read-only access 👉 Business confidentiality while remaining AML/KYC compliant. 4/ Geo-Distributed Validator Set - Permissioned validators distributed worldwide - Ensures 99.99%+ uptime, no single point of failure - Local compliance across regions: GDPR EU, US, APAC… 👉 Built for traditional finance without sacrificing system reliability. 5/ Roadmap PoA -> DPoS (From institutional trust -> sustainable decentralization) 👉 Decentralization with a roadmap without sacrificing trust. 6/ In conclusion Arc is not trying to be an Ethereum killer or a faster Solana. Arc is being built to become the Economic Operating System for financial institutions: ⚡ Sub-second finality 💵 Gas paid in stablecoins 🔐 Controlled & configurable privacy 🧾 Financial-grade compliance 🌍 Global validator distribution + long-term DPoS vision 🧑‍💻 You can also try out their technology during the ongoing testnet across the Arc ecosystem together with me. @gordonliao @dollarsterlingX @AdiSeredinschi @elk_xyz #Arc
