In 2015, the Ethereum protocol proposed a imaginative and prescient for a decentralized world pc able to rearchitecting a free and open web – faraway from the whims and constraints of centralized entities. Whereas Ethereum has turn into the muse for Web3 as we all know it, its development was underscored by the upgrades that might be required to appreciate its full potential. In consequence, 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 anticipated 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 software for crypto is that it vastly reduces the prices of processing knowledge (akin to transaction knowledge on a blockchain) with out compromising the safety or decentralization that make these financial networks distinctive.
The applying of ZK tech permits blockchain networks to show the authenticity of their operations in essentially the most environment friendly means, 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 circumstances far past what’s at present potential.

There may be little doubt amongst blockchain builders that ZK expertise represents the last word answer to blockchain scaling. For a lot of, it’s essentially the most essential growth in making certain a good web atmosphere for the free alternate of worth and digital possession of property and knowledge, all with out being subjugated to centralized management.
Till not too long ago, ZK-based scaling was restricted by its incompatibility with the Ethereum Digital Machine (EVM). It’s not strictly incompatible, after all, however maybe unfriendly. In actual fact, many business contributors projected that it could take greater than a decade to construct a performant, EVM-compatible ZK rollup. Luckily, 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 street map, with enhancements to how on-chain knowledge is saved prone to be the following step.
The belief of this street 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 said outright that ZK rollups are the answer to scaling Ethereum. Given this, it is important that the event and software of ZK tech adhere to the core beliefs of Web3, with transparency chief amongst them.
Customers can’t actually belief the outputs of a ZK-powered software if they can not independently confirm its inputs. On this means, transparency requires proving methods which have source-available code for each element.
How will ZK tech profit crypto?
As talked about, ZK has a variety of purposes however there are a number of the place there’s worth within the close to time period.
With ZK’s capacity to extend throughput and safety and scale back charges, ZK rollups may also be a significant software for the decentralized finance sector. Leveraging Ethereum’s sturdy safety and decentralization whereas offering scale in a trustless means may take DeFi to the following stage.
Equally, zero information tech may have a knock-on impact on the funds business. Crypto has didn’t turn into a broadly accepted channel for enterprise and client funds, largely a consequence of restricted scalability and excessive charges (and taxes, however that’s a separate subject with a less-technical answer). Breakthroughs akin to zkEVM look to problem this, permitting sturdy cost stacks to be realized on Ethereum.
Moreover, for blockchain gaming purposes to match the quantity of customers seen within the mainstream gaming sector, ZK rollups shall be important for processing the tons of of hundreds, if not hundreds of thousands, of micro-transactions {that a} typical blockchain recreation would require.
One other space rife for the sorts of innovation that zkEVM can convey is enterprise blockchain options. Till now, enterprise customers have been cautious of the safety points offered by decentralized networks and their perceived lack of oversight and accountability.

Zero-knowledge expertise is the very factor that may ship accountability to decentralized networks with out submitting to arbitrary oversight. Its implementation will present the sort of safety that enterprises must 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 gives 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 knowledge.
In response to the collapse of the FTX alternate, Vitalik proposed a ZK-based answer for stopping future FTXs. A cryptocurrency alternate may use Zero-Data proofs to show solvency by publishing a proof of reserves. This might enable an alternate to verify 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 tough to argue that ZK rollups will not play a central function within the broad adoption of cryptocurrency. Whereas this listing of potential use circumstances is not at all complete, what’s extra seemingly is that essentially the most helpful, groundbreaking software of ZK doesn’t but exist.
As a useful analog, think about that the explosion of social media was partly the consequence of its being an software 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.
