Zero-knowledge KYC could solve the privacy vs compliance conundrum: VC partner

Zero-knowledge Know Your Customer (KYC) would allow businesses to adhere to strict AML/CTF rules while ensuring customer privacy.

As the Web3 industry matures, Zero-knowledge Know Your Customer (zkKYC) is becoming more widely discussed as a means to comply with strict financial regulations while maintaining user privacy, according to the partner of a venture capital firm.

In an interview with Cointelegraph, John Henderson, partner at Australian-based venture capital firm Airtree Ventures said the successful implementation of a zkKYC system would be “great news for both regulators and consumers” and could increase cryptocurrency adoption:

“Institutions and retail users are more likely to participate in DeFi if they can be confident that they are complying with their AML/CTF obligations.”

Henderson explained a zkKYC system would allow users to prove certain things about themselves to service providers without having to divulge personally identifying data such as their names or identification documents.

In theory, the sharing of that information would be enough to satisfy Anti-Money Laundering (AML) and Counter-terrorist Financing (CTF) regulatory requirements placed on the crypto industry.

“[The system] involves a trusted third party validating my personal information and then issuing a cryptographic proof to my personal wallet, which I could then choose to share, or share attributes of, with financial service providers.”

The benefit of such an approach is that no personally identifying information could be leaked in the event of a security breach of a service provider such as a crypto exchange, Henderson claims, with the identification documents only recoverable when required by authorities.

Many in the crypto community have been critical of the way their personally identifiable information has been handled by some crypto platforms.

Recently, the community shared their concerns after court documents published on Oct. 5 publicly disclosed the personal information and transaction history of thousands of Celsius customers, with some warning they could be used to “dox” users.

Calls to improve privacy for individuals were also loudly sounded at the September Converge22 conference in San Francisco. 

Jeremy Allaire, CEO of stablecoin issuer Circle, expressed the need for “advancements” in technologies that prove identities and credentials while simultaneously ensuring individuals’ privacy.

Henderson however admitted that “storage of sensitive information is still an unsolved problem,” sharing two ideas on how the management of such information could take place.

“One idea would be to have trusted entities hold identity documents off-chain and port proof of identity on-chain, without the original documents. Another idea is to sign a wallet transaction with a regulatory institution, who would then register that account with an identity.”

Despite the challenge, Henderson was adamant a zkKYC protocol will form the “building blocks of on-chain reputation scores” allowing “more useful” financial products and services.

“My priority is onboarding the next hundred million users to crypto,” he said, “If we want to achieve internet scale, we need a solution for AML/CTF compliance.”

Airtree Ventures led a $4.7 million seed round into ReputationDAO on Apr. 13, a decentralized autonomous organization which aims to provide a financial reputation and identity service for decentralized finance (DeFi).

BitDAO launches $200M zkDAO to advance Ethereum scaling via zkSync

As outlined by its creators, zkDAO will be community-driven and is currently seeking contributors.

On Thursday, a proposal to fund decentralized autonomous organization zkDAO passed via treasury protocol BitDAO with close to 200 million votes cast. The proposal was authored by Matter Labs — the organization behind Ethereum scaling protocol zkSync — and Mirana Ventures.

Utilizing zk-Rollups, zkSync and its family of technologies will build layer-2 infrastructure capable of returning succinct proofs to the Ethereum network without sending the entire data. The result, if implemented, would mean a vastly speedier network. Zero-knowledge-based solutions have attracted much attention in recent months due to recurrently high levels of congestion on Ethereum, as well as exuberant gas fees. For example, Polygon is committing $1 billion to zero-knowledge tech firms and protocols. Aside from scaling, zero-knowledge proofs can also be used to obscure transactions and enhance individual privacy, such as via the Panther protocol.

As for BitDAO, it is currently one of the largest decentralized treasuries, with a balance of over $2.5 billion. In November 2021, the entity allocated $500 million to a decentralized blockchain gaming proposal. Jonathan Allen, head of Mirana Ventures and a BitDAO contributor, gave the following remarks regarding the development:

“This proposal will not only benefit the collective Ethereum scaling effort but will provide tremendous value to the BitDAO ecosystem, which continues to act as a leading force across industries as it creates entirely new purpose-built DAOs that also need to scale effectively on-chain.”

Zero-knowledge scaling tech Plonky goes live on Polygon

The move comes after Polygon allocated $1 billion to the advancement of zero knowledge technology.

On Monday, Polygon (MATIC), a layer-two Ethereum (ETH) scaling solution that is known for its fast transaction times and negligible gas fees, announced the launch of Plonky2, a zero-knowledge scaling technology, claimed to be the fastest in the world. Zero-knowledge algorithms ensure everything is correctly computed on layer two and return the succinct proof to Ethereum without sending the entire data. Instead of every miner (or staker) verifying every posted transaction, zero-knowledge allows the verification of simplified rolled-up proofs, thereby significantly speeding up the overall network.

As told by Polygon, recursive zero-knowledge proofs were largely theoretical in 2014. By 2019, it took about 120 seconds to generate them. In 2020, that number fell to 60 seconds. This year, Plonky2 is set to allow such proofs to be generated in just 0.17 seconds. The network's developers allege that it is 100x faster than existing alternatives.

Such a class of algorithms could potentially enable horizontal or linear scaling of blockchains in the future. Nodes do not need to store the history of the blockchain's transactions to be up and running, thereby increasing the network's capacity with each one added.

Polygon has committed $1 billion to the development of zero-knowledge technologies. In August, Polygon merged with the zero-knowledge blockchain Hermez Network for $250 million worth of MATIC tokens. In December, it announced the allocation of up to 250 million MATIC tokens to a deal with cryptography startup Mir. That firm specializes in the PLONK and Halo subcategories of zero-knowledge algorithms, with the latter not needing a trusted setup at all for the verification of proofs.

Here’s how Polygon is challenging the limitations of Ethereum, as told by co-founder Sandeep Nailwal

Polygon's scalability, efficient processing times and very low gas fees provide a solution to Ethereum's current network limitations, according to Nailwal.

Polygon (MATIC), a layer-two network designed for scaling and application infrastructure development on Ethereum (ETH), has been making the rounds among blockchain enthusiasts as of late. From its $1 billion investment into zero-knowledge technology to co-launching a $200 million Web 3.0 social media initiative up to integrating with Opera's web browser to make its decentralized apps accessible to 80 million Android mobile users, the network's momentum is going strong. 

But partnerships and business aside, the technological capacities of the network, especially when compared to Ethereum, are also attracting the attention of many blockchain developers. In an exclusive interview with Cointelegraph, Polygon co-founder Sandeep Nailwal talked about the extent of the network's adoption.

Cointelegraph: What are the current gas prices and transaction speeds for Polygon? And how does that compare to Ethereum?

Sandeep Nailwal (SN): From the Polygon Scan Explorer, you can see that the average block time is around 2.3 seconds. As for Ethereum, that is 15 seconds. And then the gas fees, you can see 0.001 MATIC tokens; this is a point fraction of a penny.

CT: Have there been any notable nonfungible token (NFT) drops on the Polygon network recently?

SN: None of them have become like CryptoPunks or anything, but I think Polygon's biggest kind of support is from the gaming companies [...] They all added to NFT. If you go to market, talk to any random 10 different gaming teams, they will tell you six to seven are building on Polygon.

But the notable drops on NFT, the biggest, have been Dolce and Gabbana, the brand. They made a $7 million sale recently. There are other big luxury premium watch brands, and these guys are coming in. Apart from that [...] Elon Musk minted an NFT. Jack Dorsey minted NFT of his first-ever tweet, and [...] Mark Cuban — all those were on Polygon networks only.

CT: What are some popular decentralized apps built on the Polygon blockchain? And what does their total value locked (TVL) look like?

SN: Polygon is now used by all the decentralized finance applications in Ethereum. The only one remaining was Uniswap. And the community signaled a week back that they are also launching on Polygon now. So as for the popular DApps, I would say Uniswap, Aave, Decentraland, etc. I think the TVL across the bridges is around $5 billion or $6 billion.

CT: What is your objective for investing in zero-knowledge technology?

SN: We had committed $1 billion for zero-knowledge technology, which we believe is the holy grail of blockchain scaling. And privacy is the second element — that's one thing where everybody gets confused. So you use ZK to verify computations back on Ethereum without sending back the entire data. Instead, you simply provide proof that everything was correctly computed on layer two and put a [...] succinct proof back to Ethereum.

CT: In your opinion, would further Ethereum upgrades empower the network's capacity to match that of layer-two solutions?

SN: Even if 2.0 comes in here, that will not provide enough scalability. Next year, the proof-of-stake [PoS] upgrade will keep everything the same; like Ethereum has 13 transactions per second [TPS] right now, maybe it will go to 20 TPS [after PoS], but not more than that. So that does not add anything to scalability. And let's say in three to five years, even if the sharding comes, we'll have a projection of 64 shards. And with each acting at 20 transactions per second, but that's still 1,280 transactions per second overall, right? That's still not enough for the entire world.

CT: What does Polygon's adoption currently look like?

SN: There are 3,000 plus active development teams on it. This was posted by Alchemy some time back. It should actually be up to 5,000. The daily active users on Polygon have become 50% more than Ethereum, and with gaming NFTs, we are seeing so much happening on Polygon.

ConsenSys launches Rollups for privacy-enabled transactions on Ethereum blockchain with support of Mastercard

The move would usher a new era of user privacy as public ledgers face scrutiny over their ability to be traced by blockchain data analytics firms.

On Thursday, ConsenSys, a prominent developer of Ethereum (ETH) software, announced the launch of enterprise software ConsSys Rollups. The service, designed on the basis of zero-knowledge (ZK) proofs, is meant to protect specific transaction elements, such as account balances, sender and recipient wallet addresses and transaction amounts to secure each user's privacy.

Zero-knowledge proofs enable the validation of sensitive encrypted information, such as personal data, by nodes without revealing the data underneath. Such cryptographic techniques have gained enormous popularity in recent years, as users fear their crypto transactions are at-risk of being tracked by blockchain forensic firms such as a Chainalysis. The nature of public ledger blockchains has made all transactions available for anyone to view since their inception, making their underlying tokens less private than physical cash transactions in certain ways.

The Rollups feature would be able to support privacy-enabled CBDCs, decentralized exchanges, micropayments, and taxes. "ConsenSys Rollups enables vastly more scalability in addition to strong privacy protections to both enhance solutions for existing use-cases and enable new use-cases. This innovative solution will help accelerate the building of the future of finance", said Madeline Murray, global lead of protocol engineering at ConsenSys. Mastercards' engineering team helped in part to design the solution.

Raj Dhamodharan, executive vice president of digital assets and blockchain products and partnerships at Mastercard, added:

We're in the early stages, but are starting to see efficiencies in how permissions and private chain product constructs use open-source technologies. Our work with partners like ConsenSys will continue to advance this space.

Mastercard has taken a slow but steady approach to cryptocurrency adoption. In an interview with Cointelegraph editor-in-chief Kristina Cornèr the day prior, Mastercard's executive vice president of market development Liza Oakes said the company is "looking at CBDCs, stablecoins and how to support their developments."

Polygon to invest up to 250M MATIC into zero-knowledge tech

If fully vested, it would be a $627.5 million investment into zero-knowledge technology at today’s MATIC price.

Ethereum scaling solution Polygon has announced it will dedicate a maximum of 250 million MATIC tokens ($627.5 million) to a deal with zero-knowledge cryptography startup Mir.

Zero-knowledge algorithms enable external validators to verify encrypted transactions or documents without revealing the sensitive information hidden underneath. It is useful for complex decentralized finance applications, such as decentralized ride-share apps or decentralized health insurance, where nodes need to verify the personal data of blockchain participants without risking privacy leaks.

Mir specializes in developing two subcategories of zero-knowledge proofs: PLONK and Halo. Both represent advancements over previous SNARK and STARK cryptography techniques, allowing proofs to be generated in seconds.

While PLONK still requires a trusted setup for validation, Halo algorithms can accomplish the task in a decentralized manner. Speed is a core design consideration in zero-knowledge proofs. Complex information to be passed over blockchains, such as redacted photo IDs, can take up substantial size, thereby affecting the applicability of transactions.

“Polygon plans to focus on ZK cryptography as the end game for blockchain scaling,” said Sandeep Nailwal, co-founder of Polygon.

“We have made a strategic decision to explore and encourage all meaningful scaling approaches and technologies at this stage. We believe this is the way to establish Polygon as the leading force and contributor in the ZK field and onboard the first billion users to Ethereum.”

The acquisition of Mir is a part of a greater $1 billion commitment to developing zero-knowledge technology by Polygon.
