Canaan’s Record Q2 Revenue Amid Profitability Struggle

Leading crypto exchange platform OKX has disclosed plans to discontinue its mining pool services, marking a strategic shift for the platform.Photo by engin akyurt on UnsplashService shutdown within one monthThe move, outlined by the firm in a notification to platform users on Friday, involves ceasing new user registrations effective immediately. Existing users will be granted access to the mining pool until Feb. 25. All mining pool-related services on OKX will be completely halted by Feb. 26. Mining Pools data reveals that OKX holds the 36th position among the top 70 bitcoin-focused mining pools, boasting a total hash rate slightly exceeding 496 TH/s. The decision to phase out mining pool services was attributed to "business adjustments," as communicated by OKX, though further details were not provided regarding the specific nature of these adjustments. Previously, OKX's mining pool supported various proof-of-work cryptocurrencies and offered staking services. However, over recent years, many supported assets had been terminated. Presently, the website only displays bitcoin, litecoin and ethereum classic pool services. Once accounted for 5% of all BTC blocks minedOKX's bitcoin mining pool had once accounted for around 5% of the blocks mined on the network. However, a setback occurred on October 16, 2020, when the crypto exchange temporarily suspended withdrawals due to one of its private key holders “cooperating with a public security bureau in investigations.” This led to a significant drop in hashpower connected to the pool, from 9,000 PH/s to 20 PH/s. The pool's current 528 TH/s now represents less than 0.0001% of bitcoin’s total hash rate. Industry trend formingThis strategic move by OKX reflects the evolving landscape of the crypto industry and the challenges faced by mining pools, particularly in the context of regulatory and operational adjustments within the market. The decision may even amount to a formative trend, given that global crypto exchange platform rival KuCoin made a similar move back in August. At the time, KuCoin outlined its plans to temporarily suspend its bitcoin and litecoin mining pools. Although it suggested a temporary halt to such services, there was no indication of when such mining-related services would resume. A company spokesperson stated:“We will see if it is needed to restart based on the market and users’ demand in the future.” Bitcoin halving pressuresOKX’s decision to discontinue mining pool services comes ahead of bitcoin's anticipated fourth halving in April, which is expected to reduce miner rewards from 6.25 to 3.125 BTC. The halving is casting a shadow over the mining sector. Miners' business cost per bitcoin mined is going to increase significantly. Some industry commentators speculate that the break-even point for miners will reach an unsustainable level. NASDAQ-listed Riot Blockchain, in particular, is being singled out as potentially being susceptible due to its cost structure. Miners have had a difficult couple of years, working their way through the bear market component of the last market cycle. That period saw leading miner Core Scientific declare bankruptcy. The company has since restructured and has been relisted on the NASDAQ.  

HashKey Report Outlines Risks of Liquid StakingLiquid staking derivatives (LSD) are not without their potential pitfalls according to a report published by Hong Kong’s HashKey Capital.Photo by Shubham Dhage on UnsplashLiquid staking exceeds $22 billionThe report, which was published by the digital asset manager and finance house in July, emphasizes the pressing need for enhanced decentralization to counteract the risks associated with this growing trend of liquid staking.The figures themselves are impressive. This year, the total value locked in the liquid staking derivatives market has surged past the $22 billion mark. Correspondingly, the market capitalization of LSD projects has skyrocketed to $18 billion, indicating a substantial influx of interest and investment.However, the growth that these protocols are witnessing also presents a dual-edged conundrum for the Ethereum ecosystem. HashKey Capital’s report underscores that despite the advantages these protocols might offer their respective communities and token-holders, they could potentially destabilize the Ethereum ecosystem in multifaceted ways.Centralization riskAs evident in HashKey Capital’s overview, several LSD protocols heavily rely on a limited number of node operators, effectively centralizing a significant portion of validator nodes. This centralization trend, as highlighted by the report, is a cause for concern. The concentration of node operators raises red flags, as it contradicts the fundamental tenets of decentralization that underpin blockchain technology.The report articulates the adverse effects of centralization in the realm of liquid staking. It points to the dangers of reduced competition and a heightened risk of censorship.The report raises an important caution: “There is a heightened possibility of censorship with centralized staking players, as they may be subject to incentives or regulatory pressure to censor transactions. This can potentially result in a disruption of the trust within the network.”Security threatsCentralization also ushers in security threats. The dominance of major staking players makes the Ethereum ecosystem more susceptible to 51% attacks. Furthermore, the potential for collusion among centralized stakers looms large, leading to actions that counteract the very essence of decentralization, such as front running and malicious maximal extractable value (MEV) susceptibility.However, amidst these centralization risks, HashKey Capital acknowledges that most protocols are in their nascent stages. Many of them have devised strategies to incorporate distributed validator technology into their protocols, a proactive step towards fostering greater decentralization and resilience.HashKey Exchange awarded retail services licenseIn an unrelated development, HashKey Exchange received approval on Wednesday to upgrade type 1 and type 7 licenses, allowing it to cater to retail investors in Hong Kong. This accomplishment comes a mere two months after the city introduced its Virtual Asset Service Provider (VASP) licensing framework on June 1.In this evolving landscape, HashKey Capital and OSL were among the pioneer licensed exchanges under the city’s earlier voluntary program. Now, the new regulations stipulate that crypto trading platforms must obtain a license to serve retail investors, further solidifying Hong Kong’s commitment to cultivating a thriving crypto ecosystem.As the HashKey Capital report and recent developments in Hong Kong demonstrate, there’s a lot in play relative to both crypto regulation, protocol design and new product innovation. The challenges posed by centralization in liquid staking underscore the importance of vigilance and corrective action. Meanwhile, Hong Kong’s aspirations to become a crypto stronghold offer a beacon of hope in an ever-evolving regulatory landscape.

Polymarket activity under scrutiny in Taiwan due to election contractsTaiwanese law enforcement is currently delving into the activities of online influencers and community members promoting Polymarket contracts related to the upcoming presidential election which is due to be held on Jan. 13.Polymarket is a New York-based Ethereum-centric prediction market. The platform runs on the Ethereum layer-2 scaling solution network Polygon. The project invites platform users to bet on the outcomes of a broad spectrum of events, ranging from politics to entertainment.Users deposit USDC stablecoin, choose an event to bet on and purchase “outcome shares” through USDC. The user has the ability to trade those shares anytime before the resolution of the contract.Photo by Ethan Lin on UnsplashPossible election law violationsThe Taiwanese investigation came to light in a report by Taiwan-based crypto publication BlockTempo, which was published last week. The investigation comes as concerns arose about potential violations of Taiwan’s Presidential and Vice Presidential Election and Recall Act, which explicitly prohibits gambling on election outcomes.Multiple influencers and crypto community members have reportedly been subpoenaed for their involvement in Polymarket contracts, allowing users to place bets on the January election. At present, the betting pool for the election holds over $300,000, with a market prediction favoring the Democratic Progressive Party’s Lai Ching-te, also known as William Lai, with a 78% chance of winning.However, the legality of such betting activities is in question under Article 88–1 of Taiwan’s election law. It stipulates that anyone gambling on the outcome of an election or recall in a public place or a place open to the public may face imprisonment, short-term detention or a fine of up to NT$100,000 ($3,196.85).Sherman Lin, an attorney at Taipei-based Lin & Partners, emphasized the seriousness with which law enforcement views gambling activities related to presidential elections in Taiwan. He explained that broad legal interpretations under the Presidential Election and Recall Act have led to investigations and convictions of gambling website operators targeting Taiwanese gamblers. Lin stated:“Law enforcement agencies in Taiwan are vigilant in investigating any gambling activities related to presidential elections.”“Broad legal interpretations have been applied to gambling crimes under the Presidential Election and Recall Act, leading to investigations and convictions of gambling website operators in Taiwan targeting Taiwanese gamblers,” he added.Prohibited in United StatesComparing the situation to the United States, where gambling on election outcomes is illegal in most states, Lin noted that enforcing such regulations often falls under the jurisdiction of the Commodity Futures Trading Commission (CFTC). Polymarket’s Terms of Use explicitly prohibit usage by U.S. persons.Despite potential legal consequences for gambling activities in Taiwan, including participation, promotion and platform hosting for betting pools like Polymarket, Lin pointed out that enforcing actions against overseas entities poses jurisdictional challenges. Taiwan’s legal reach is primarily limited to domestic actors, creating complexities in addressing decentralized platforms like Polymarket.Lin suggested that law enforcement may focus on online influencers who promoted the Polymarket contract, as seen in previous cases involving the collapse of the unlicensed crypto exchange JPEX in Hong Kong.Moreover, while there are legal precedents for pursuing centralized entities organizing election gambling, Lin highlighted that no established legal precedent in Taiwan currently exists for decentralized platforms organizing election betting.
