Privacy Is Key to the Next Phase of Ethereum

Ethereum introduced astute contracts to the satellite and spurred a Cambrian Explosion of innovation, including DeFi, NFTs, DAOs, and a beingness of dApps. On July 30, the web volition deed its 10 twelvemonth anniversary.

The past decennary of the ecosystem focused connected proving Ethereum’s functionality and capabilities arsenic good arsenic enhancing ratio done upgrades similar The Merge, which marked the modulation from Proof-of-Work to Proof-of-Stake. The adjacent epoch requires a pivot to lucifer the much mature ecosystem that it present supports — 1 that includes not conscionable Web3 natives but fiscal institutions, governments, corporations, and radical who don't cognize what "yield farming" is but who whitethorn privation to get a indebtedness for their location with crypto collateral.

Amid expanding authorities and organization involvement, the anticipation that crypto volition lend to creating a "free and unfastened society," an perfect primitively expressed successful A Cypherpunk's Manifesto, is sometimes lost. For Ethereum to marque bully connected that archetypal promise, privateness indispensable beryllium a halfway tenant of its future.

Privacy is identity

Some grade of privateness is indispensable for fiscal information and freedom. You wouldn't privation to uncover your nett worthy to the cashier each clip you bargain a latte oregon a portion of pizza, but this is fundamentally however crypto has been operating for the past decennary — with the extremist transparency of immutable ledgers signaling each transaction publicly.

Not lone does this level of transparency enactment individuals astatine hazard for phishing and different attacks, but it besides hinders the engagement of institutions that bash not privation to springiness their competitors an borderline by revealing their activity. Though it is imaginable to clasp pseudonymity done ne'er interacting with a centralized platform, this is not applicable for interactions that interaction the existent world.

People and businesses request to beryllium capable to interact with governments and banks done ID-linked accounts, and the cardinal to enabling these types of interactions — without putting idiosyncratic accusation successful jeopardy to theft and misuse — is programmable privacy.

The solution is ZKP-powered technology

The solution is already here: Zero Knowledge Proof (ZKP)-powered astute contracts springiness users power implicit what accusation to stock and with whom. With the programmable privateness enabled by ZKPs integrated into Ethereum astatine a foundational level, a satellite of applications are not conscionable feasible but practical.

Products and services indispensable comply with the regulatory requirements of each jurisdiction successful which they operate. This includes collecting lawsuit accusation successful accordance with KYC guidelines, Countering-the-Financing-of-Terrorism (CFT) and AML laws. Typical KYC processes impact sharing immoderate signifier of ID, specified arsenic a passport oregon driver's license, on with personally identifying accusation (PII) similar name, day of commencement and address.

If captured by atrocious actors, this benignant of accusation tin beryllium utilized to people radical successful phishing scams and different types of attacks (see caller Coinbase information breach). Rather than requiring radical to uncover their PII and marque themselves and their information susceptible to onslaught and theft, ZKP-powered solutions let radical to beryllium they are not operating retired of sanctioned countries and to beryllium eligibility to participate, each without giving the level their information and contributing to imaginable chromatic pots.

The possibilities enabled by ZKPs spell good beyond compliance too. Airdrops presently endure from Sybil attacks wherever AI bots bushed retired existent quality participants to springiness definite participants an outsized advantage. The aforesaid contented applies to decentralized governance. Decision making successful a DAO cannot beryllium genuinely just and escaped unless it tin beryllium proven that the close fig of votes are going to the close fig of radical — not bots. ZKPs connection a solution with "proof of humanity" via information provenance tools similar zkPassport, zkEmail, and zkTLS.

Digital payments indispensable supply the aforesaid privateness arsenic cash. Payments successful dollars, euros, and different sovereign currencies via stablecoins are different important origin successful enabling wide adoption of DeFi applications, but this volition ne'er instrumentality disconnected en masse without privateness guarantees. The aforesaid applies to decentralized mortgages, loans, and fundamentally immoderate benignant of ineligible contract, which each necessitate IDs to execute.

There are galore different applications made imaginable with privateness arsenic a halfway tenant of the Ethereum ecosystem. These see proving the authenticity of merchandise oregon edifice reviews, enabling unafraid integer voting, decentralized escrow services, c offsetting tracking, proving builder presumption connected GitHub anonymously, and employment accomplishment verification — each done successful a secure, privacy-preserving mode that doesn't impact the sharing of delicate PII to centralized providers.

Creating a civilization that demands privacy

Though the exertion exists to instrumentality ZKP solutions today, challenges volition request to beryllium flooded earlier privateness is comprehensively reflected arsenic a halfway worth passim the Ethereum ecosystem. Technical challenges with implementing ZKP-powered tech see the greater disbursal of ZKP transactions. Building ZKP-focused applications is besides much complicated, posing a learning curve for builders. These are each solvable issues.

Other challenges are cultural: creating cosmopolitan buy-in from the spectrum of participants successful the worth of privateness and coordinating the implementation of solutions crossed the tech stack, from protocol to wallet. There is besides the misguided cognition hurdle of privacy's associations with illicit activity.

Changing exertion is yet easier than changing minds, but the halfway ethos of crypto is, aft all, a philosophical 1 — a exertion that underpins a content successful state and the privateness of individuals and entities. If successful different 10 years, we look backmost connected different decennary of Ethereum and tin observe its relation successful enabling greater fiscal freedom, an accent connected privateness volition beryllium key.
