Aleo

Aleo is a privacy-focused Layer 1 blockchain and cloud computing network. The detailed introduction is as follows:

- Technical Features

It adopts zero-knowledge (ZK) technology, leveraging smart contracts, arbitrary computation, and zero-knowledge proofs (ZKP) to protect privacy. Its zkCloud off-chain trustless cloud computing environment allows programs to execute privately, securely, and inexpensively with unlimited runtime. The SnarkOS system, a privacy-centric zero-knowledge operating system, serves as the foundational pillar of the Aleo platform.

- Consensus Mechanism

Aleo employs the AleoBFT consensus mechanism, a hybrid consensus algorithm combining Proof of Stake (PoS) and Simplified Proof of Work (PoSW). This mechanism decouples block production from Coinbase, enabling validators to handle block generation while allowing provers to perform large-scale computational tasks on demand. It also incentivizes user participation through Aleo credits to enhance network security.

- Network Participants

The main participants include validators, provers, and stakers:

• Validators operate nodes, verify transactions, and participate in network consensus to earn rewards.

• Provers use specialized hardware to generate proofs, solve cryptographic puzzles, and earn Aleo credits.

• Stakers support network security by locking Aleo credits and receive staking incentives.

- Programming Language

Aleo uses Leo, a statically typed programming language inspired by Rust. Aimed at providing developers with an intuitive experience, Leo facilitates building private applications on the Aleo blockchain by abstracting underlying cryptographic concepts, thus lowering the development threshold.
