NEW: @Circle launches @Arc mainnet, an L1 blockchain purpose built for stablecoins, RWAs, and agentic payments.
Circle's Chief Economist and Head of Research, @GordonLiao, on what Arc is designed to be:
"It is a general purpose platform and operating system that will support economic coordination between humans and machines."
Arc Mainnet is live.
Arc launches as the Economic OS for the internet: an open platform for global markets, real-time value movement, tokenized assets, and agentic economic activity.
Arc is more than a blockchain.
It launches as a full-stack financial platform with assets, applications, interoperability, developer infrastructure, and Circle platform services live from day one.
Arc delivers USDC as native gas, deterministic sub-second finality, EVM compatibility, and institutional validators.
It integrates with Arc Studio, App Kits, Arc Portal, Circle Agent Stack, CCTP, Gateway, CPN, and StableFX.
A complete economic platform at genesis.
Arc launches with infrastructure for:
→ Agentic economic workflows
→ Lending and borrowing
→ Trading and liquidity
→ Onchain FX
→ Payments and settlement
→ Tokenized assets
→ Exchanges, wallets, custody, compliance, data, and developer tooling
190+ institutional and ecosystem builders are building across Arc.
The dollar's share of FX reserves is at a two-decade low. Treasury convenience yields have turned negative.
End of dollar dominance? No — but financial innovation could reshape the system.

@antonttc@barnabemonnot@ethlabs_org@eth_systems Think bigger. 13-14 figures. What would secure trillions or tens of trillions? proof of stake in the 9 figures won't cut it. One needs strong governance, necks to choke, literally. It's not defi maxi, and that's by design

Presented at the Federal Reserve Bank of Kansas City's Jackson Hole Economic Policy Symposium, Aug 27–29, 2026. Grateful to the organizers and discussants — and to my co-authors @EswarSPrasad and Tony Zhang.
Three futures for the international monetary system:
1. Greater concentration — most likely on today's path
2. True multipolarity — best, but needs deep markets, strong institutions, innovations
3. Fragmentation — the riskiest
The outcome isn't preordained. Policy decides.
