Enter Aptos Confidential Transactions (ACTs)—a breakthrough that brings privacy to the public blockchain without compromising on security or decentralization. It's the best of both worlds, finally working together.
In the world of blockchain, transparency has always been a double-edged sword. While it ensures integrity and trustlessness, it also makes every transaction—and every wallet balance—publicly visible. That’s a dealbreaker for businesses, institutions, and individuals who need privacy to operate securely and compliantly.
In traditional finance, confidentiality isn’t just preferred—it’s required. Banks don’t disclose account balances, and payroll systems don’t publish salaries on a public ledger. Yet on most blockchains today, anyone can see who sent what, when, and how much. That lack of privacy has been a barrier to adoption in real-world financial systems.
Aptos Confidential Transactions solve this. With ACTs, the amounts you send—and even your account balances—are encrypted. Not even the validators running the network can see them. Everyone can verify that a transaction occurred, but only the intended parties (and optionally, an auditor) can see the details.
ACTs introduce powerful privacy features that are easy to integrate:
ACTs aren’t full anonymity tools like some privacy coins. The sender and receiver addresses remain public—what’s hidden are the amounts. That design choice makes ACTs compliant-ready: transparency where necessary, confidentiality where it matters most.
If regulations require oversight, ACTs allow users to designate authorized auditors. These auditors can view the encrypted details, enabling compliance with financial regulations while keeping the broader public in the dark. It’s a smart balance between privacy and accountability.
Under the hood, ACTs use advanced encryption combined with zero-knowledge proofs—mathematical techniques that prove statements (like "this wallet has enough balance") without revealing the data behind them. The result? A public blockchain with provable security and private financial data.
With ACTs, developers can build privacy-preserving apps on Aptos that meet the standards of real-world finance—from payroll systems to enterprise payments and private donations. These systems can now live on-chain, without exposing sensitive financial data.
ACTs are live now on the Aptos devnet, meaning developers can start building and experimenting today.
