Aleo is similar to Ethereum in that it maintains a public ledger, but with one key difference: it uses zero-knowledge technology to ensure privacy. While blockchains like Ethereum require users to expose their data (e.g., sharing your date of birth), Aleo allows developers to verify information without revealing personal data.

Zero-knowledge technology allows someone to prove that a statement is true without revealing any additional information. For example, with Aleo, you can prove you are over 21 without disclosing your exact age. This is used to protect users' personal information while still allowing access to online services.

Traditional blockchains are public by nature, meaning that any data shared (such as personal information) can be viewed by all nodes. This creates privacy concerns and increases the risk of data breaches. Aleo addresses this by allowing encrypted and private data to be verified without being shared.

Aleo helps prevent data breaches by using zero-knowledge proofs. This means users can share proofs of information (like age or identity) without exposing sensitive data. This minimizes the risk for both users and organizations, as businesses no longer need to store and secure personal information, reducing their exposure to cyber attacks.

Aleo Systems is the company that developed the Aleo Network. After the mainnet launch, Aleo Systems will relinquish control of the network, which will then operate independently as an open-source, decentralized system. Aleo Systems will continue to build products and services on top of the network.

Aleo allows users to provide necessary information (like identity verification) without exposing personal data. Organizations using Aleo don't need to store sensitive data, reducing regulatory risks and the potential for data breaches. The network enables businesses to operate securely while maintaining user privacy.

Aleo is currently in the final stages of launching its mainnet. Once fully operational, the Aleo Network will function independently, similar to Ethereum. Aleo Systems will then focus on building zero-knowledge applications on top of the network.

Developers can use Aleo to create applications that migrate data onto the ledger. They have the flexibility to choose whether the data remains confidential (e.g., personal information) or public (e.g., weather reports). This allows for secure and private applications without sacrificing the power of blockchain technology.
