The move comes as Worldcoin faces scrutiny and seeks to address concerns surrounding data protection.Photo by Esmonde Yong on UnsplashAddressing privacy concernsThe "proof-of-personhood" crypto project has been under scrutiny for its data collection practices. Last month, temporary bans were imposed by Spain and Portugal, halting Worldcoin's data collection activities. The project offers WLD tokens to users in exchange for iris scans to create their personal World ID, prompting privacy advocates' concerns. Government attention and oversightWorldcoin's high-profile nature, coupled with Sam Altman's involvement, has drawn significant government attention. Countries like Germany, France, Argentina, Kenya and South Korea have initiated investigations into the project's data collection practices. Despite challenges, senior government officials continue to engage with Worldcoin amidst growing concerns about artificial intelligence threats like deepfakes. Strengthening government relationsTo address regulatory concerns, Worldcoin's parent company, Tools for Humanity, appointed Trevor Traina, former U.S. ambassador to Austria, as Head of Global Affairs. Traina emphasized the importance of meeting policymakers' expectations regarding data privacy and security. New privacy measuresIn response to regulatory pressures, Worldcoin introduced "Personal Custody," discontinuing the storage of biometric data for new signups. Additionally, users can now request the deletion of their iris codes, and stricter age verification measures have been implemented to prevent minors from signing up. These measures were developed in consultation with privacy experts and data protection authorities. Despite challenges, Worldcoin has assigned over five million World IDs, according to project data. 

KuCoin Halts Bitcoin and Litecoin Mining Pools Amidst Strategic ShiftIn an announcement on Tuesday, Seychelles-based cryptocurrency exchange KuCoin revealed its decision to temporarily suspend its Bitcoin and Litecoin mining pools, effective from 16:00:00 on August 15, 2023 (UTC).Photo by Traxer on UnsplashChanging business strategyThis move is attributed to KuCoin’s evolving business strategy, although specific details remain undisclosed. The exchange expressed its regret for any inconvenience caused and extended gratitude for users’ continued support.It appears that the company wants to focus on core business activities and for that reason, it’s terminating its mining pool activity. That said, the discontinuation was described in its statement as being “temporary” although that has been left open-ended with no indication of if or when it would bring the service back into operation.The company is open to the idea of revisiting the facilitation of mining pools in the future. “We will see if it is needed to restart based on the market and users’ demand in the future,” a spokesperson for the company told The Block.To ensure miners’ uninterrupted earnings during the suspension, KuCoin advised users engaged in cryptocurrency mining to transition their Bitcoin (BTC) and Litecoin (LTC) miners to alternative mining pools before the specified suspension date. Additionally, the exchange emphasized the importance of backing up and preserving mining records and related data, recommending users complete these actions before August 27.Presently, the KuCoin Bitcoin mining pool maintains a hash rate of 9.08 exahash per second (EH/s), while the Litecoin pool operates at 3.90 terrahash per second (TH/s). These figures contribute to the broader hash rate landscape, where the entire Bitcoin network boasts a hash rate of 349.19 EH/s, compared to the Litecoin network’s 792.16 TH/s.Workforce reductionIt is clear that the company is in the process of adjusting to current market conditions. Last week, rumors surfaced of a plan to effect a workforce reduction. That prompted KuCoin’s CEO Johnny Lyu to respond, clarifying that the exchange’s operations are running smoothly. Dismissing layoff speculation, Lyu highlighted the exchange’s steady expansion and strong growth as demonstrated by the H1 2023 report. The report showcased an increase in users and new listings, underscoring the platform’s vitality and development.Mandatory KYCIn recent months, KuCoin has also implemented mandatory Know Your Customer (KYC) requirements, obligating users to undergo verification processes. Existing customers who fail to complete KYC procedures will be unable to make deposits. With over 20 million registered accounts, the exchange felt that it needed to improve on its level of regulatory compliance and security measures.It’s highly likely that an action taken by authorities in New York in the United States in March prompted KuCoin’s decision to tighten up on KYC. At that time, the New York Attorney General said that action was being taken against KuCoin due to its failure to register as a securities and commodities broker-dealer.As KuCoin undergoes these changes, the suspension of its mining pools raises questions about the broader implications for its business strategy and the potential impact on miners within its ecosystem. That said, the firm is not alone in making changes, with most crypto exchanges having had to adjust to a business and regulatory environment that has changed considerably since the 2021 crypto bull run.

Scroll’s zkEVM Launches on Ethereum MainnetScroll, the Seychelles-headquartered project behind the Ethereum layer-2 network of the same name, has officially made its debut on the Ethereum mainnet.Photo by Zoltan Tasi on UnsplashAttempting to solve for scalabilityThe project team announced the development via a press release which was published on Tuesday. The network launch signifies the latest in a series of attempts by various layer-2 projects, including Polygon and StarkWare, to address the persistent challenges of high transaction fees and network congestion that have hindered Ethereum’s usability in recent times. Speaking to layer-2 development, co-founder Sandy Peng stated:“We see a future where the vast majority of value transfer takes place on Layer 2s on Ethereum. What will drive that adoption is improved user and developer experience.”After testing and refinement on its testnet, Scroll believes that it is in a good position to play an active role within the Ethereum ecosystem by providing a general-purpose, zero-knowledge Ethereum virtual machine (zkEVM) roll-up.The project has 900,000 wallet addresses in active use on its testnet, having executed seven million transactions since August. The testnet has seen over 55 million transactions during its year-long operation.At its core, Scroll’s mission is to combine Ethereum’s network security with reduced fees and lower latency, making it an attractive proposition for existing Ethereum projects. According to Peng, Ethereum developers can seamlessly deploy their projects on Scroll and harness the groundbreaking zkEVM technology.Incorporating bytecodePeng emphasized the significance of zkEVM’s ability to batch proofs efficiently, resulting in faster transaction speeds and cost reductions, thanks to its bytecode-level compatibility.Bytecode, in the realm of computer programming, simplifies intricate machine cryptography, making code more accessible for computer hardware. Scroll allows deployed smart contracts to store the bytecode of their transactions, which is then sent to a centralized zkEVM node. This node verifies the transaction’s accuracy without revealing its content. Once verified, the transaction’s status is updated on the Ethereum network, eliminating the need for re-execution. Peng pointed out:“Thanks to this feature, Ethereum devs can leverage all the same tools they are familiar with, ensuring that everything operates seamlessly right from the start.”Scroll’s mainnet code was subject to audits conducted by four major auditing firms, namely Zellic, Trail of Bits, OpenZeppelin, and KALOS, in an effort to ensure robust security and reliability.Efforts towards greater decentralizationWhile Scroll’s current implementation offers compelling features, the team is actively researching ways to further enhance the network’s decentralization. Currently, if the sequencer goes offline, the protocol halts, creating a potential vulnerability. To address this, the Scroll team is working on a protocol upgrade that will enable “forced batches.” This update will allow permissionless publication of batches through the base layer, even in the event of a sequencer halt.Peng elaborated on the team’s vision, stating: “Mid-term, the goal is to minimize the probability of a sequencer halt through decentralization.” This approach aims to bolster the network’s resilience and ensure a smoother user experience.While headquartered in the Seychelles, the project has its origins in China through its Chinese founders, Ye Zhang and Haichen Shen, alongside Peng, with many of its 60-strong project team based in mainland China and Hong Kong.
