Cracking the Code: Overcoming Challenges of On-chain FHE/ part 1

TLDR: FHE vs. ZKP:Fully Homomorphic Encryption (FHE) offers a more flexible solution than ZKPs for blockchain, enabling private data validation. Their combination could transform confidential decentralized finance (DeFi). Challenges in FHE Implementation:…

EIP-7212 precompile for SGX's attestations can be used for Multi-Prover Rollups or Private Smart Contracts on L1 or by TEE builders (Trusted Execution environment) Rollups or any kind of coprocessors need proof mechanisms to prove that off-chain computation is correct and there's no fraud. These proof mechanisms are called Integrity Proofs. These proofs help to remove the need for trust in the output of a program. **There are 5 examples of Integrity Proofs:

A) Naive Replay: Everyone runs the same program under the same conditions, so we can be sure that computation is correct.

B) Trusted Execution Environments: A specific hardware designed not to reveal data to the operator. C) Reputation-based integrity: In this type, we trust people to run the programs without fraud.

D) Fraud Proofs: Prove the invalidity of any program. TEE is basically a specific hardware that no one can access internally and cannot change the program inside. There is an assumption that TEE is not compromised, or if there is a backdoor, the operator is not acting maliciously.

E) Zero Knowledge Proofs: Prove the validity of any program with mathematical proofs. what is SGX? it is a type of TEE designed by Intel, allowing developers to build specific programs & applications that need computational integrity, such as building bridges (e.g., Avalanche Bridge - they're not OS), multi-prover rollups, and protecting from MEV (SUAVE). And thanks to SGX, we can build third-party attestation services to make these SGX's verifiable on-chain, but we have a limitation: the only curve SGX's attestation service supports is P-256, which is not natively supported on Ethereum. The EIP-7212 precompile is so helpful for smart contract wallets because it allows cheap and secure verification for Passkeys and Webauthn, it is also helpful for verifying DNSSEC signatures onchain.** @web3privacy1

The Data Ownership Protocol (DOP) is utilizing zero-knowledge proofs in order to allow flexible transparency on top of Ethereum L1. DOP allows users and DApps to store assets and make transactions privately, or selectively disclose token holdings and historical information.

FHE-Rollups: Scaling Confidential Smart Contracts on Ethereum and Beyond – whitepaper

Abstract  We introduce the concept of Fully Homomorphic Encryption (FHE) Rollups: a more scalable technique for executing arbitrary confidential smart contracts. Recent works [1, 16, 39] have shown that FHE is a viable solution for adding confidentiality…

Axiom released http://halo2repl.dev, a browser-based REPL that allows developers to write ZK circuits in Javascript.

halo2-repl packages circuit generation and proving in a really easy-to-use way:
abstracts away the hard details of using a ZK proving library: access basic primitives directly in Javascript
enables proof generation directly in the browser, avoiding the infra overhead to get started
* no wrangling with dependencies or new languageshttps://blog.axiom.xyz/halo2-repl/ @web3privacy1
