PADO is an innovative network that makes internet data available in web3 smart contracts. The availability of this data expands the capabilities of smart contracts, and enables the monetization of personal data within a privacy-protected framework.

In response to an increasing demand for data ownership and heightened privacy, there arises a necessity for a conduit that facilitates the shift from closed platforms to a more open internet, and PADO aptly addresses this requirement. Diverging from conventional on-chain data practices, PADO introduces a secure and trustless method for transferring diverse data types to decentralized networks.

Individuals can leverage PADO for direct data migration, facilitated by a user-friendly Chrome extension that streamlines the generation of proofs for a wide range of data, including KYC (know-your-customer) status, central exchange balances, banking account balances, credit scores, and much more. The possibilities are expansive, limited only by your imagination. PADO opens up a realm of data resources for exploration and utilization.

The Uniqueness of PADO

PADO empowers end users to verify the authenticity of data obtained through the Transport Layer Security (TLS) protocol. As TLS is widely deployed across the internet, users can effectively validate various internet data. The innovative cryptographic protocol at the core of this mechanism is known as garble-then-prove, designed by the PADO cryptography team.

Leveraging multi-party computation (MPC) with state-of-the-art VOLE-based Interactive Zero-Knowledge Proofs (IZK), also developed by the PADO cryptography team, ensures the entire solution remains light enough to operate in browsers. The protocol also operates more than 10x faster than existing solutions.

PADO has also created a lightweight tool that lets users selectively disclose and prove any statement related to the authenticated data by incorporating popular zkSNARKs algorithms. For further details, please refer to our technical paper.

To enhance user experience and alleviate their computation burden, the PADO cryptography team is introducing an innovative Verifiable Outsourcing Computation Network by developing efficient zkFHE schemes. In this network, users have the capability to outsource private data encrypted under Fully Homomorphic Encryption (FHE) schemes to trustless workers. These workers handle the computational tasks on the ciphertext and produce a succinct proof that allows anyone to verify the integrity of the computation. This novel protocol is expected to be much faster than the native combination of FHE and ZKVM, and is currently in active development by the PADO team.

PADO’s Use Cases

There are several potential applications for PADO. For instance, PADO is at the forefront of enhancing privacy and security by integrating its off-chain data hooks on Uniswap v4. These protocols typically involve establishing a compliant and institutional pool for users possessing verifiable physical identities, and the provision of a transaction fee discount for individuals with a trading history from centralized exchanges. These innovative combinations introduce a novel degree of customization and privacy to future DeFi protocols.

PADO can also be used by users concerned about privacy while engaging in social networking and gaming activities in web3. They can use PADO to safely share their behaviour data from the Steam platform, and to earn prop airdrops from GameFi projects without worrying about potential privacy leakage or misuse.

Finally, PADO’s zkAttestation technology allows real-world financial assets such as stocks, bonds, precious metals, and real estate to be encrypted and quantified for secure asset management and circulation of RWA assets on the smart contract layer.

PADO and Linea

Since its inception, PADO has received attention and support from various organizations, including grants from the Ethereum Foundation to build interactive zero-knowledge systems; and participation in the first cohort of the Consensys Fellowship and the Berkeley Blockchain Xcelerator program.

PADO is crucial in transitioning from the conventional centralized web to a blockchain-enhanced, value-centric internet, utilizing innovative technologies to offer a comprehensive solution for secure, trustless, and comprehensive data attestation and verifiable outsourcing computation network.

PADO is delighted to join the Linea ecosystem and become a core contributor to Verax. Introducing more valuable data into Linea and collaborating with other ecosystem participants is very important to PADO.
