Taiko Labs Raises Funding to Build Ethereum-Equivalent zkEVMTaiko Labs, a crypto startup focused on scaling the Ethereum blockchain, has successfully raised a total of $22 million in two funding rounds.According to a blog article published to the startup’s website on Thursday, the first funding round, a $10 million seed raise, was led by Sequoia China and concluded in the third quarter of 2022. The second round, a recent pre-Series A round, raised $12 million and was led by Generative Ventures, according to co-founder Daniel Wang.Photo by cottonbro studio on PexelsBroad investor participationNotable investors in the two rounds include IOSG Ventures, GSR, and GGV Capital, as well as angel investors like Patricio Worthalter, the Founder of the Proof of Attendance Protocol (POAP), Tim Beiko from the Ethereum Foundation, and Anthony Sassano, Co-Founder and COO of the decentralized virtual world, The Sandbox. Taiko Labs has not disclosed its valuation.Scaling EthereumThe primary focus of Taiko Labs is to develop a scaling solution for the Ethereum blockchain that closely adheres to Ethereum’s design and ideology. The company refers to its product as a Type 1 zero-knowledge Ethereum Virtual Machine (zkEVM).Vitalik Buterin, the inventor of Ethereum, emphasized the importance of Type 1 zkEVMs for scaling the Ethereum layer 1 in a blog post. Taiko Labs aims to extend Ethereum’s capabilities by sticking to the Ethereum Virtual Machine (EVM) specification and leveraging its best properties, as explained by Matthew Finestone, co-founder of Taiko Labs.On Wednesday, Taiko Labs released its latest version, its alpha-3 testnet, Grímsvötn, marking a significant milestone on its path to a decentralized and Ethereum-equivalent ZK-EVM.Taiko backstoryThe journey towards Taiko Labs began when Daniel Wang and Matthew Finestone worked together at Loopring Foundation, a trading and payment protocol based on zk-rollup technology. Wang served as the founder and CEO of Loopring Foundation from July 2017 until November 2021, while Finestone worked as the head of business for three years.Wang initially intended to build a decentralized social network but encountered a major obstacle — the lack of infrastructure and scalability. This realization led to the birth of the idea for Taiko Labs.Wang commented on the funding milestone, stating: “We believe that we are now on the cusp of having a truly decentralized Ethereum-equivalent ZK-rollup. This is our core mission at Taiko and we are incredibly proud to partner with leading investors who share our uncompromising vision.”The successful financing rounds will enable Taiko Labs to ensure a successful launch of its mainnet. However, the company is considering raising additional capital, partly to establish an ecosystem investment fund that will attract decentralized applications (dApps) and developers to the ecosystem.In terms of organizational structure, Taiko Labs plans to follow in Ethereum’s footsteps. Wang told The Block: “We are going to quickly convert the organization into a non-profit one. Ideally, we’ll operate very similarly to the Ethereum Foundation.”These successful funding rounds provide a solid foundation for Taiko Labs’ future endeavors, and the company is aiming to make a meaningful impact on the global adoption of blockchain technology with its focus on scaling.

Bank of Japan Publishes Results of CBDC PoCThe Bank of Japan (BoJ) recently concluded the second phase of its central bank digital currency (CBDC) proof of concept (PoC) project, which began in April. The results of this phase were published on Monday, and they shed light on key aspects such as the comparison between account-based and token-based CBDCs and the management of holding limits for users with multiple accounts.Photo by Manuel Cosentino on UnsplashToken-based CBDCsThe experiments conducted by the central bank covered a wide range of topics. Among the most intriguing findings were the advantages and disadvantages of token-based CBDCs and how to effectively impose holding limits for users with multiple CBDC balances.Token-based CBDCs have garnered interest from various central banks, with some adopting the UTXO token model used by Bitcoin without the use of a distributed ledger. A UTXO or unspent transaction output, defines where a blockchain transaction starts and finishes. The Bank of Japan explored this model and analyzed its pros and cons.In the initial proof of concept, both account-based and token-based CBDCs were examined, considering scenarios where the central bank managed the ledger or shared it with intermediaries like banks. In the token-based model, fixed token denominations were used, similar to physical cash in countries like India, and a centralized ledger was employed. However, in the recent phase, the central bank utilized flexible value tokens similar to UTXO and shared ledger functions with intermediaries.The Bank of Japan favored the flexible value token model due to its ability to handle multiple requests simultaneously. However, it acknowledged that this model may require more technical resources compared to the account-based approach. Challenges may arise when implementing additional functions, such as holding limits, while maintaining optimal performance. The European Central Bank (ECB) also noted in a recent report that most payment providers are accustomed to account-based payments and would incur costs to adapt to token-based systems.Another significant aspect explored by the BoJ was how to impose holding limits when users have multiple CBDC balances through different intermediaries. The challenge lies in determining if the overall holding limit has been breached without compromising user privacy.Homomorphic encryptionOne possible solution discussed in the report is the use of homomorphic encryption, which enables computations to be performed on encrypted data without it first needing to be decrypted. That allows for the necessary checks without intermediaries accessing the specific data being checked. Although this solution may slightly increase processing time, it could introduce a higher risk of data inconsistencies.Alternatively, a simpler approach proposed by the central bank is to establish a per-account holding limit and a limit on the number of accounts a single user can hold, rather than imposing global limits. Ideally, users with multiple accounts would have a higher per-account holding limit compared to those with fewer accounts.Phase 3 underwayWith the next pilot phase already underway, the BoJ aims to test the end-to-end process flow and identify challenges related to integrating with external systems. Additionally, they are creating a CBDC Forum to gather input from the private sector, ensuring a collaborative approach to CBDC development.While investigation and research into CBDCs continues, the BoJ has said that it will make a final decision on CBDC implementation by 2026.

South Korea’s financial regulator is preparing a second major cryptocurrency bill that would expand investor protections, strengthen stablecoin safeguards, and potentially impose governance changes at the country’s largest exchanges, as domestic token projects warn that regulatory uncertainty is curbing growth. The Financial Services Commission (FSC) is drafting the Digital Asset Basic Act, a so-called “phase two” bill that follows an earlier virtual asset user protection regime which took effect in July 2024. According to Yonhap News, the bill is expected to address stablecoin risks by requiring issuers to hold reserve assets in instruments such as bank deposits and government bonds, and to deposit or place in trust at least 100% of outstanding issuance with banks or other designated custodians. It would also extend existing financial-sector rules to crypto firms in areas including disclosures, terms and conditions, and advertising. In addition, the proposal could impose no-fault liability on virtual asset service providers for losses stemming from hacks or system failures, in line with standards under Korea’s Electronic Financial Transactions Act, which governs traditional financial institutions and payment services.Photo by Timothy Ries on UnsplashGovernance dominance at exchangesA separate report by KBS said the draft bill includes measures to overhaul governance at South Korea’s four major crypto exchanges—Upbit, Bithumb, Coinone, and Korbit—which together serve about 11 million users. The FSC has raised concerns about concentrated control by founders and major shareholders, and is considering a governance framework similar to that applied to alternative trading systems (ATS) under Korea’s Capital Markets Act. That could include limits designed to prevent any single shareholder from holding too much control, capping controlling stakes at around 15% to 20%. Under Korea’s current Capital Markets Act, an ATS is generally barred from holding more than 15% of voting shares, including those held by related parties, with limited exceptions allowing stakes of up to 30%. If similar limits were applied to crypto exchanges, the changes could affect Dunamu, the operator of Upbit. Dunamu Chairman Song Chi-hyung holds a stake in the mid-20% range and, under the proposal as described, could face pressure to sell roughly 10% of his holdings. The proposal could have implications for the deal, as Dunamu is pursuing a merger with Naver Financial through a comprehensive stock swap. While the bill’s broad outlines are taking shape, regulators are still working to narrow differences over stablecoin rules, and the final proposal is expected to be submitted to the National Assembly next year. Key unresolved issues include eligibility requirements for stablecoin issuers, whether to establish an interagency consultative body during the licensing process, initial capital thresholds, and whether a single entity should be allowed to both issue and distribute stablecoins. The core dispute centers on who should be allowed to issue stablecoins. The Bank of Korea is said to favor limiting issuance to consortia in which banks hold at least a 51% stake, while the FSC is believed to oppose writing a mandatory bank ownership threshold into law, arguing that such a requirement could limit broader participation by technology firms. ‘Kimchi coin’ listings stall amid cautionEven as policymakers push ahead, regulatory uncertainty is curbing growth among South Korean blockchain projects. News1 reported that Upbit listed only one token from a domestic project in 2025, out of 54 tokens added for trading since the start of the year—the native token of Story, a peer-to-peer intellectual property network powered by blockchain and co-founded by Korean entrepreneur Lee Seung-yoon. Upbit also removed 10 tokens during the period, seven of which were so-called “kimchi coins,” a colloquial term for tokens originating in South Korea or developed by Korean teams. Industry participants attribute the removals to increasingly risk-averse behavior by exchanges amid regulatory uncertainty, which can complicate promotional efforts and trust-building while constraining early-stage liquidity. TradFi players seek crypto integrationsWhile local token projects face headwinds, interest from traditional financial institutions appears to be picking up. Chosun Biz reported that Mirae Asset Financial Group is considering an acquisition of Korbit, with its non-financial affiliate Mirae Asset Consulting seen as a potential buyer of shares from major shareholders NXC and SK Planet. Industry analysts estimate the deal could be worth up to 140 billion won ($97 million). The group’s founder, Park Hyeon-joo, has said he is developing a strategy to bridge traditional and digital assets, arguing that it is time to prepare for the next wave of financial innovation. In payments, EBN Industrial News reported that BC Card has signed a memorandum of understanding (MOU) with U.S.-based crypto exchange Coinbase to test USDC payments in South Korea. The pilot would integrate BC Card’s QR payment system with wallets on Coinbase’s Base blockchain to assess whether USDC can function as a viable payment method at local merchants.
