Overview

Internet privacy is crucial as it safeguards personal data, preserves autonomy, and protects against surveillance. It fosters trust in online interactions and ensures individuals can control what they share, making it fundamental in the digital age.

However, we’ve all had our data sold to third parties without consent, becoming the product of internet. This became one of the main goals for the new internet era - web3 to solve. In web3, privacy is a cornerstone of the decentralized internet, offering users greater control over their data and enhanced consent mechanisms, with technologies like DID, dStorage, ZKP, MPC and FHE.

「Rebuild Ownership」as a series global hackathon, is designed to gather the pioneer protocols in the space and offer hackers a holistic experience of tackling on internet privacy using web3 technologies. We are thrilled to have partners like Filecoin, Fhenix, etc.

About DataverseOS

DataverseOS brings a new data paradigm for individuals to control their web footprint data using a single wallet. The core is an Internet data operating system, which transforms browser into self-sovereign computer and run web-scale applications over decentralized stacks. Developers can create storage-based dApps that return data ownership to users, e.g. content platforms, social networks, cloud storage, tools for thought, AI marketplace and more.

About Fhenix

Fhenix is the first blockchain powered by fully homomorphic encryption to bring Computation Over Encrypted Data to EVM smart contracts.

About PSE (TLSNotary)

PSE (Privacy and Scaling Explorations) is a research lab within the Ethereum Foundation building free tools that expand the world of cryptography. The focus is on Privacy, Scalability, and the use of zero-knowledge proofs.

TLSNotary is a PSE project that promotes privacy-preserving data provenance and portability, assisting individuals in liberating their data from silos and utilizing it as they see fit, enhancing data composability on the web.

About Filecoin

Filecoin, the world’s largest decentralized storage network, that allows users to store, request, and transfer data via a verifiable marketplace. FVM unlocks boundless possibilities, ranging from dataDAOs, to perpetual storage, to financial services for miners (e.g. collateral lending, liquid staking, insurance protocols), to decentralized compute and Layer 2 networks (such as reputation systems, and incentive-aligned content delivery networks, and more.

About Tableland

Tableland is a decentralized SQL database. Build web3 native apps—powered by event-driven on-chain workflows for data mutability—and develop using smart contracts or SDKs for permissionless & low cost data writes and reads.

About PADO

PADO is a zkAttestation protocol, dedicated to bring Internet data into web3 smart contracts, expanding the capabilities of smart contracts, and enabling the monetization of personal data within data flows under privacy protection.

About Linera

Linera is a layer-1 blockchain protocol designed to bring the elastic scaling of web2 to web3, initially inspired by the low-latency payment protocol FastPay developed at Meta.

Linera introduces the idea of operating many lightweight chains, called microchains, in parallel in the same set of validators. Compared to traditional multi-chain systems, a benefit of running all the microchains in the same set of validators is that creating chains does not impact the security model.
