Three blockchain projects focused on privacy — Arc, Canton, and Tempo — have collectively raised more than $1 billion in funding, underscoring a growing institutional push into secure, scalable digital finance. The rounds close as regulators globally tighten oversight on public ledgers, making privacy-preserving tech a hot commodity for banks and fintechs looking to stay compliant without sacrificing transparency.
Who's behind the money
The facts don't name which investors led the rounds or the exact valuations, but the sheer size — north of $1 billion split among three firms — suggests blue-chip backers. Arc is building a privacy layer for enterprise smart contracts; Canton focuses on confidential smart contracts for financial markets; Tempo is developing a privacy-focused payments network. Combined, they cover much of the institutional use case: trade settlement, payment rails, and data-sharing between banks.
Why privacy blockchains now
This isn't a retail play. Institutional interest in privacy blockchains has accelerated since late 2025, when the European Union's MiCA regulations took full effect and several US states passed their own digital asset custody rules. Banks need blockchains that can keep transaction details hidden from competitors while still allowing regulators to peek under the hood. Arc, Canton, and Tempo all pitch exactly that — a ledger that's public enough to audit but private enough for a balance sheet.
What comes next
With over a billion in fresh capital, the three projects are likely to start hiring, scaling testnets, and courting pilot partners among the world's biggest financial institutions. Tempo has already announced a pilot with a European clearinghouse; Canton is in talks with a consortium of US banks. Arc hasn't named any clients yet but says deployment is on track for late 2026. The cash gives them runway to actually ship — a luxury most blockchain startups don't have.
The next concrete milestone to watch: whether any of the three gets a production deployment inside a tier-one bank before the end of the year. That would validate the thesis better than any funding round.
