What is Aztec (AZTEC)?

Deep Dive

1. Purpose & Value Proposition

Aztec solves the transparency problem of public blockchains like Ethereum. While transparency ensures security, it exposes sensitive financial data. Aztec provides a "privacy shield," allowing users and institutions to conduct confidential transactions and computations on Ethereum without revealing amounts, identities, or contract logic. This enables use cases like private DeFi, confidential voting, and institutional settlements that require selective disclosure for compliance.

2. Technology & Architecture

Aztec is a zkRollup, a type of Layer 2 that batches transactions off-chain and submits a cryptographic proof (a zero-knowledge proof or ZKP) to Ethereum for verification. Its key innovation is a hybrid state model that manages both private data (in encrypted "notes") and public data simultaneously. Private computations occur on the user's own device, generating a ZKP that validates the transaction without revealing its details. This client-side proving preserves decentralization and enhances privacy.

3. Tokenomics & Governance

The AZTEC token is central to network operations and governance (Aztec Network). It is an ERC-20 token on Ethereum L1. Holders can stake AZTEC to run sequencers (validators) that propose and validate blocks, earning emissions. Staking also grants governance rights, allowing participants to vote on protocol upgrades. Furthermore, AZTEC can be used to pay for gas fees on the Aztec network, creating inherent utility within its ecosystem.

Conclusion

Aztec is fundamentally a programmable privacy layer for Ethereum, combining the security of Ethereum with the confidentiality required for sophisticated financial applications. As regulatory and institutional interest in blockchain grows, how will Aztec's model of "verifiable but invisible" execution shape the future of private smart contracts?
