ALEO

ALEO is a Layer 1 (L1) Smart Contract Platform and Privacy Blockchain that leverages Zero-Knowledge (ZK) technology to build a private-by-default internet. It enables developers to create cryptographically secure decentralized applications (dApps) without exposing sensitive user data. ALEO works by taking computation off-chain using snarkVM, allowing provers to publish only a proof of computation on-chain, which is then verified by validators. This unique approach, underpinned by the AleoBFT consensus mechanism and the Leo programming language, ensures high scalability, unlimited application runtime, and robust data privacy within the blockchain ecosystem.

ALEO solves the critical problem of data privacy and security in the decentralized web. Traditional blockchains often expose user data publicly, leading to privacy concerns and vulnerability to breaches. ALEO, as a Privacy Blockchain utilizing Zero-Knowledge (ZK) proofs, allows users to prove something is true without revealing the underlying sensitive information, such as proving age without stating an exact birthdate. This approach provides increased data security for users and reduces the burden on organizations to store sensitive data. Furthermore, it simplifies the complex task of building private applications, making ZK technology accessible for all Web3 developers.

The aleo token (ALEO) serves multiple core utilities within the ALEO blockchain ecosystem. Primarily, it grants access to blockspace and computational resources on the network, required for users to submit transactions and for developers to deploy smart contracts. The aleo token also incentivizes network participants; provers are rewarded for solving zero-knowledge puzzles, and validators earn tokens for securing the network through the AleoBFT consensus mechanism. Additionally, the aleo token can be staked to contribute to network security and earn rewards, and will power decentralized governance after the mainnet launch, allowing holders to influence the protocol's future.

Aleo uses zero-knowledge proofs to validate computations without revealing underlying data, enabling selective disclosure through view keys. This allows users to prove transaction validity to auditors without exposing sensitive details, balancing compliance and confidentiality.

Provers require GPUs optimized for parallel computation to efficiently generate zk-SNARKs. Minimum specifications include 8GB VRAM GPUs, though high-end setups with multiple GPUs significantly improve proof generation speed and reward potential.

The dual record/mapping system allows developers to choose optimal visibility per data element. This flexibility enables use cases like poker games where initial card distribution remains private, while revealed cards transition to public state – impossible in monolithically private chains.

Applications can port logic using Aleo's Ethereum-compatible tooling, but must adapt to Leo's programming paradigm. While this requires learning new patterns, developers gain built-in privacy and ~100x gas cost reductions by moving computation off-chain.

Unlike standard delegated staking, Aleo requires validators to maintain prover infrastructure to solve Coinbase puzzles. This dual role (staking + proof generation) creates stronger security guarantees against lazy validation, as validators must continuously prove computational commitment.
