🔐Programmable Privacy Made Possible: Decentralized Private Computation🔐
Decentralized Private Computation (DPC) enables confidential off-chain computations with publicly verifiable results on the blockchain, ensuring privacy without compromising transparency or security. Platforms like Aleo use DPC to help developers build privacy-focused applications.
By leveraging zero-knowledge proofs and Aleo's record model, DPC provides a foundation for programmable privacy, unlocking new possibilities for handling sensitive data in areas like DeFi and healthcare. This approach maintains blockchain transparency and security while addressing privacy concerns.

Decentralized Private Computation (DPC) enables users to perform private computations off-chain while verifying the results publicly on the blockchain. It underpins ZEXE (Zero-Knowledge Execution), the foundation of the Aleo blockchain.
Aleo achieves DPC through a record model, a privacy-preserving data structure that stores arbitrary payloads and links ownership via public keys. Transactions include only serial numbers of consumed records, commitments of created records, and zero-knowledge proofs (ZKPs), revealing no sensitive data or account details.
🌌⭐The Aleo Network: Scalable, Cost-Effective, and Secure⭐🌌
Using ZKPs, Aleo offloads execution off-chain, ensuring scalability with high throughput and low latency. Validators verify small, constant-size cryptographic proofs, avoiding computational overhead. This reduces costs, prevents DOS attacks without gas fees, and ensures security via cryptographic guarantees rather than cryptoeconomic reliance.
Aleo’s approach ensures private, scalable, and secure computations, setting a new standard for blockchain privacy.
🔎Programmable Privacy Is Here🔎
Decentralized Private Computation (DPC) makes programmable zero-knowledge applications a reality, powered by two key components: shielded identities and shielded transactions.
· Shielded Identities allow users to authenticate and interact privately, enabling selective data sharing without compromising confidentiality.
· Shielded Transactions protect all transaction details, preventing exploitation of mempool activity, identity theft, and Maximal Extractable Value (MEV) attacks that target trading orders and liquidity provisioning.
These features combine in zkCloud, a trustless, off-chain execution environment where shielded identities interact via shielded transactions. Cryptographic proofs ensure transaction integrity.
zkCloud supports local application execution or delegation to third-party services that handle proof generation and transaction submission, enabling marketplaces for private computation.
This framework allows Aleo to deliver a private, programmable, and high-performance network by separating execution from state, submitting only cryptographic proofs to the blockchain.
