Whereas proponents of totally homomorphic encryption (FHE) have typically touted it as a greater privateness answer than zero-knowledge (ZK) proofs, Man Itzhaki, the founder and CEO of Fhenix, stated each are cryptographic-based applied sciences which, when mixed, can kind a strong and environment friendly encryption layer. To assist this viewpoint, Itzhaki pointed to a analysis examine whose findings recommend that “combining ZKPs with FHE may obtain totally generalizable, confidential decentralized finance (defi).”
The Blockchain and AI Converging
Regardless of their nice promise, privateness options have but to turn out to be an necessary a part of blockchains and decentralized apps (dapps). In his written solutions despatched to Bitcoin.com Information, the Fhenix CEO stated one of many causes for this can be the perceived burden they create to builders and customers. To beat such issues, Itzhaki proposed making these options EVM-compatible and likewise bringing FHE encryption capabilities to the programming language Solidity.
In the meantime, when requested how builders and customers can defend their privateness in a world the place blockchain and synthetic intelligence (AI) are converging, the founding father of Fhenix — an FHE-powered Layer 2 — stated that step one can be to boost consciousness in regards to the presence of rising dangers or challenges. Taking this step will drive builders to design purposes that tackle these challenges.
For customers, Itzhaki stated one of the best ways to guard themselves is to “educate themselves about protected utilization and make the most of instruments that assist private information safety.” Elsewhere, in his solutions despatched through Telegram, Itzhaki additionally touched on why the much-vaunted Web3 mass adoption has not come.
Under are Man Itzhaki‘s solutions to all of the questions despatched to him.
Bitcoin.com Information (BCN): Very often, the dearth of a refined consumer expertise is seen as the largest roadblock to Web3 mass adoption. Nevertheless, some see privateness issues as one other main impediment, particularly for institutional adoption. In your opinion, what do you see as the largest obstacles the Web3 ecosystem must collectively overcome to turn out to be commonplace?
Man Itzhaki (GI): To start with, a scarcity of a way of safety whereas interacting with blockchain-based purposes. Many individuals are deterred from utilizing it as a result of it “feels” much less safe than conventional purposes that supply “built-in” safety, even at the price of centralization.
The second problem is the final unhealthy consumer expertise that the house commits you to. For instance, the sense of safety (or performance) is broken enormously when customers lose funds on account of small working errors that may occur to anybody. The difficult nature of working most decentralized purposes is a big impediment to mass adoption.
One other situation is rules. Blockchain adoption is hindered by the destructive sentiment of regulators and conventional markets, primarily on account of associations with felony activity- we have to discover a strategy to enable customers to maintain their information non-public (on public blockchains) whereas additionally permitting them to be compliant with the legislation.
FHE expertise holds loads of potential for dealing with these challenges (by encrypted computation operate). By introducing native encryption to the blockchain, we will facilitate a greater sense of safety (for instance by encrypting the consumer’s belongings steadiness), assist purposes like account abstraction that considerably cut back the consumer’s complexity when interacting with the blockchain and allow decentralized identification administration that’s wanted for compliance.
BCN: Relying on the merchandise and use circumstances, the blockchain ecosystem has a variety of privateness wants. Do you see FHE changing zero-knowledge ZK proofs and trusted execution environments (TEEs) or can these progressive applied sciences co-exist?
GI: That’s an incredible query as there’s a severe dialogue concerning the efficacy of any single privacy-preserving expertise to resolve all information encryption wants and scenarios- On account of excessive variations between competing encryption applied sciences (price, complexity, UX)..
You will need to perceive that whereas each FHE and ZKP are cryptographic-based applied sciences, they’re very completely different. ZKP is used for the verification of information, whereas FHE is used for the computation of encrypted information.
Personally, I imagine that there isn’t a ‘one-stop-shop’ answer, and doubtless we’ll see a mixture of FHE, ZKP and MPC applied sciences that kind a strong, but environment friendly encryption layer, primarily based on particular use case necessities. For instance, latest analysis has proven that combining ZKPs with Absolutely Homomorphic Encryption (FHE) may obtain totally generalizable, confidential DeFi: ZKPs can show the integrity of consumer inputs and computation, FHE can course of arbitrary computation on encrypted information, and MPC might be used to separate the keys used.
BCN: Are you able to inform us about your challenge Fhenix and the totally homomorphic encrypted digital machine (fhEVM) in addition to the way it blends into the present chains and platforms?
GI: Fhenix is the primary Absolutely Homomorphic Encryption (FHE) powered L2 to deliver computation over encrypted information to Ethereum. Our focus is to introduce FHE expertise to the blockchain ecosystem and tailor its efficiency to Web3 wants. Our first improvement achievement is the FHE Rollup, which unlocks the potential for delicate and personal information to be processed securely on Ethereum and different EVM networks.
Such development signifies that customers (and establishments) can conduct encrypted on-chain transactions, and it opens the door for added purposes like confidential trustless gaming, non-public voting, sealed bid auctions and extra.
Fhenix makes use of Zama’s fhEVM, a set of extensions for the Ethereum Digital Machine (EVM) that permits builders to seamlessly combine FHE into their workflows and create encrypted sensible contracts with none cryptographic experience, whereas nonetheless writing in Solidity.
We imagine that by bringing devs the most effective instruments for using FHE on prime of present protocols will pave the best way for the formation of a brand new encryption customary in Web3.
BCN: Whether or not it’s FHE, ZK proof or one thing else, the privateness options themselves have an uphill activity to turn out to be an integral a part of blockchains and decentralized apps (dapps). What components or methods would make it simpler for builders to combine privateness options into the present chains and platforms?
GI: I come from a really sensible background, and that’s the reason once we simply began designing Fhenix, it was clear to us that we wanted to make FHE as simple as doable for builders and customers. As such our first determination was to verify we’re EVM suitable and convey the FHE encryption capabilities in Solidity as a way to cut back the burden on builders, and never require them to study a brand new, particular language for coding. That additionally signifies that builders don’t want to carry any cryptographic experience or FHE data for growing dapps.
Lastly, we’re fixing for developer expertise in growing encryption-first, purposes. That signifies that we concentrate on creating the most effective stack for builders, to ease the event course of as a lot as doable.
BCN: With FHE, one can enter information on-chain and encrypt it whereas having the ability to use it as if it’s non-encrypted. The info is alleged to stay encrypted and personal throughout transactions and sensible contract implementations. Some imagine that this stage of on-chain privateness may transcend fixing privateness points and unlock use circumstances that weren’t doable earlier than. Might you illustrate by examples a few of these potential use circumstances, if any?
GI: By way of related use circumstances, each software that requires information encryption can profit from using FHE in some kind or one other. Essentially the most attention-grabbing use circumstances are those who profit enormously from performing computations on encrypted information, like:
- Decentralized identification
- Confidential Funds
- Trustless (Decentralized) gaming
- Confidential defi
One nice instance is On line casino gaming. Think about a situation the place the supplier distributes playing cards with out understanding their values—a glimpse into the potential of totally non-public on-chain encryption. That is just the start. FHE’s capacity to include information privateness and belief into the blockchain is crucial for each recreation makers and gamers, and elementary to future gaming improvements and use circumstances.
One promising avenue for attaining that is by Fhenix’s FHE Rollups, which empower builders to create customized app chains with FHE seamlessly built-in, all whereas utilizing acquainted Ethereum Digital Machine (EVM) languages.
Within the context of gaming, FHE Rollups provide the power to construct gaming ecosystems with FHE expertise at their core. For example, one roll-up might be devoted solely to on line casino video games, guaranteeing the entire privateness and safety of those video games. In the meantime, one other rollup, totally interoperable with the primary, may concentrate on large-scale player-versus-player (PvP) video games.
BCN: Synthetic intelligence (AI) and blockchain, two of a number of the hottest applied sciences proper now, seem like converging. Now some individuals imagine AI may have each optimistic and destructive impacts on Web3 consumer privateness and security. Specializing in the destructive impact, what precautionary measures ought to builders and customers take to safeguard on-chain privateness?
GI: The very first thing can be elevating consciousness of the rising challenges within the web, and in Web3 house particularly, which ought to commit builders to contemplate these dangers when designing their purposes. Customers, alternatively, want to coach themselves about protected utilization and make the most of instruments that assist private information safety.
By way of technological precautionary measures- one of many use circumstances I’m personally curious about is how we, the customers, can inform the distinction between AI-generative content material and human-made content material. Testifying to the origin of the content material is a key characteristic of blockchains, and I’m assured we’ll see apps that assist observe information origin sooner or later.
Particularly, for FHE, we’re exploring methods to assist create higher AI modules by permitting customers to share their information for AI coaching, with out the danger of shedding their privateness.
