In 2015, the Ethereum protocol proposed a imaginative and prescient for a decentralized world laptop able to rearchitecting a free and open web – faraway from the whims and constraints of centralized entities. Whereas Ethereum has develop into the muse for Web3 as we all know it, its development was underscored by the upgrades that might be required to understand its full potential. Consequently, layer 2 has emerged as clear frontrunners within the race to scale the community for mass adoption. Programs utilizing zero-knowledge (ZK) applied sciences are among the many most promising – and their potential isn’t restricted to scaling.
Mihailo Bjelic is the co-founder of Polygon. This text is a part of Crypto 2023.
ZK-powered expertise is predicted to revolutionize myriad sectors from gaming to funds, and from digital id to enterprise options. Wanting forward, 2023 guarantees to be the 12 months ZK tech actually begins to take off.
What’s zero-knowledge expertise?
Zero-knowledge expertise refers to instruments that use cryptography to show that one thing is true with out revealing any further data apart from the truth that it’s true. The worth of such a instrument for crypto is that it enormously reduces the prices of processing information (reminiscent of transaction information on a blockchain) with out compromising the safety or decentralization that make these financial networks distinctive.
The appliance of ZK tech permits blockchain networks to show the authenticity of their operations in essentially the most environment friendly approach, utilizing the fewest potential steps. This has the ability to be transformational for Web3 growth by decreasing prices, growing throughput capability, and increasing potential use instances far past what’s at the moment potential.

There’s little doubt amongst blockchain builders that ZK expertise represents the final word answer to blockchain scaling. For a lot of, it’s essentially the most essential growth in guaranteeing a good web surroundings for the free change of worth and digital possession of belongings and information, all with out being subjugated to centralized management.
Till just lately, ZK-based scaling was restricted by its incompatibility with the Ethereum Digital Machine (EVM). It’s not strictly incompatible, in fact, however maybe unfriendly. The truth is, many trade contributors projected that it might take greater than a decade to construct a performant, EVM-compatible ZK rollup. Thankfully, it took significantly much less time than that.
Whereas the Ethereum Merge in 2022 was instrumental in transitioning the community from proof-of-work (PoW) to the extra environment friendly proof-of-stake (PoS), it represents simply step one within the broader Ethereum highway map, with enhancements to how on-chain information is saved more likely to be the subsequent step.
The conclusion of this highway map could take years, although it’s clear that ZK expertise is part of Ethereum’s long-term imaginative and prescient. Certainly, Ethereum co-founder Vitalik Buterin has acknowledged outright that ZK rollups are the answer to scaling Ethereum. Given this, it’s important that the event and utility of ZK tech adhere to the core beliefs of Web3, with transparency chief amongst them.
Customers can not actually belief the outputs of a ZK-powered instrument if they can’t independently confirm its inputs. On this approach, transparency requires proving programs which have source-available code for each part.
How will ZK tech profit crypto?
As talked about, ZK has a variety of functions however there are a number of the place there’s worth within the close to time period.
With ZK’s skill to extend throughput and safety and scale back charges, ZK rollups can even be a significant instrument for the decentralized finance sector. Leveraging Ethereum’s strong safety and decentralization whereas offering scale in a trustless approach might take DeFi to the subsequent degree.
Equally, zero information tech might have a knock-on impact on the funds trade. Crypto has didn’t develop into a extensively accepted channel for enterprise and shopper funds, largely a consequence of restricted scalability and excessive charges (and taxes, however that’s a separate difficulty with a less-technical answer). Breakthroughs reminiscent of zkEVM look to problem this, permitting strong fee stacks to be realized on Ethereum.
Moreover, for blockchain gaming functions to match the quantity of customers seen within the mainstream gaming sector, ZK rollups can be important for processing the tons of of hundreds, if not tens of millions, of micro-transactions {that a} typical blockchain recreation would require.
One other space rife for the sorts of innovation that zkEVM can deliver is enterprise blockchain options. Till now, enterprise customers have been cautious of the safety points introduced by decentralized networks and their perceived lack of oversight and accountability.

Zero-knowledge expertise is the very factor that can ship accountability to decentralized networks with out submitting to arbitrary oversight. Its implementation will present the type of safety that enterprises have to work together with decentralized blockchains.
ZK tech can be being utilized to digital id, offering a decentralized, privacy-first means for customers to confirm their credentials and id with out ever revealing private data. Such an ID presents a decentralized answer for customers to adjust to know-your-customer (KYC) and anti-money laundering (AML) checks with out counting on third events to retailer and course of their information.
In response to the collapse of the FTX change, Vitalik proposed a ZK-based answer for stopping future FTXs. A cryptocurrency change might use Zero-Information proofs to show solvency by publishing a proof of reserves. This might permit an change to substantiate it has the liquidity to cowl buyer withdrawals with out revealing the delicate enterprise data contained therein.
With a lot potential coming from a single technological breakthrough, it is more and more troublesome to argue that ZK rollups will not play a central position within the broad adoption of cryptocurrency. Whereas this listing of potential use instances is certainly not complete, what’s extra doubtless is that essentially the most helpful, groundbreaking utility of ZK doesn’t but exist.
As a useful analog, take into account that the explosion of social media was partially the consequence of its being an utility that would solely exist on the web – it had no actual world antecedent. Someplace there’s a younger dev with a nascent thought for one thing that may solely be constructed on a blockchain.
ZK rollups and zkEVMs are bringing Ethereum’s imaginative and prescient of a decentralized net into focus.
