OpenAI Special Projects Lead Brad Lightcap to Depart, Core Executive Role Previously Held as COO Undergoes Multiple Adjustments
Odaily News: Brad Lightcap, Special Projects Lead and former Chief Operating Officer (COO) at OpenAI, is set to leave the company. Over the past year, Lightcap's responsibilities at OpenAI have been adjusted multiple times, with his most recent role being in charge of "special projects."Lightcap has long been a core member of OpenAI's management team. Earlier in 2026, during a company executive reshuffle, he transitioned from the COO position to lead special projects, overseeing cross-company matters including complex deals and strategic investments, reporting directly to CEO Sam Altman. His departure comes at a time when OpenAI is continuously expanding its commercialization efforts, advancing enterprise business, and pursuing strategic partnerships. Previously, the company had undergone multiple rounds of organizational restructuring, including transferring some COO responsibilities to other executives.Brad Lightcap joined OpenAI in 2018, having previously worked at Y Combinator and JPMorgan. He has been one of the key operations and business leaders during OpenAI's transformation from a research institution into a commercial AI company. (The Information)
Plan B: Scarcity, Not Short-Term Price Fluctuation, Is the Core of Bitcoin's Long-Term Value
Bitcoin analyst Plan B stated on the X platform that the core of Bitcoin's long-term value lies in scarcity, not short-term price fluctuations.Plan B believes that many people focus on Bitcoin's price charts, while the S2F model he uses focuses on the degree of asset scarcity. This model measures scarcity through "existing supply ÷ annual new production," where the S2F for gold is approximately 60. Due to Bitcoin's fixed total supply of 21 million coins and its predictable issuance schedule, its S2F is currently around 120 and continues to rise over time.The Bitcoin halving mechanism is an important driver of the S2F model. Approximately every four years, the Bitcoin network reduces the block reward by half, decreasing new supply and roughly doubling the S2F level, making it the core supply-side event observed by the model.Plan B emphasized that the S2F and its upgraded version, the S2FX model, predict long-term average value rather than precisely forecasting market tops or bottoms. Bitcoin's price typically fluctuates around the model's estimated value, and investors should focus on multi-year cycle averages rather than single-day price highs. Additionally, Plan B believes that as scarcity increases, Bitcoin is undergoing different stages of development, including proof of concept, payment network, "digital gold"/store of value asset, and institutional-grade financial asset. Each increase in scarcity could bring new market narratives and capital inflows.However, Plan B also reiterated that "all models are wrong, but some are useful." He stated that the S2F model is merely a tool for long-term understanding of Bitcoin's scarcity, not a trading signal or a "crystal ball" for price prediction. Although the model has withstood major events such as the COVID-19 pandemic and China's mining ban, it still has limitations.
SEC Exempts AI Data Center ABS from Core Regulatory Requirements, Further Opening Financing Channels for Tech Companies
According to Bloomberg, the U.S. Securities and Exchange Commission (SEC) recently issued an internal letter explicitly exempting asset-backed securities (ABS) related to AI data centers from core investor protection regulations introduced after the 2008 financial crisis, including the "risk retention" clause requiring issuers to retain a portion of the debt. The SEC determined that data centers are not financial assets that liquidate over time, therefore securities linked to them should not be subject to the same regulatory constraints as ABS related to auto loans or mortgages. Although this move does not constitute a formal rule change, since companies had previously voluntarily complied with relevant regulations out of compliance prudence, the substantive impact cannot be underestimated. In terms of market size, the annual issuance volume of data center ABS has surged from $2.4 billion in 2020 to $15.5 billion in 2025, growing more than sixfold in five years, and is expected to hit a new record high in 2026.
JPYC completes approximately $38 million Series B funding round, with AZ-COM Maruwa Holdings participating and funds earmarked for payments to 2,300 truck drivers
: Japanese yen stablecoin operator JPYC Inc. has announced an extension of its Series B funding round, bringing total funding to approximately 6 billion yen, or roughly $38 million. The latest investment includes approximately 1 billion yen (about $6.3 million) from Tokyo-listed logistics company AZ-COM Maruwa Holdings. Core business: operating JPYC, a stablecoin pegged 1:1 to the Japanese yen. JPYC launched the stablecoin in October 2025 and became the first digital currency to be registered as an official electronic payment instrument under Japan's revised Payment Services Act. Each JPYC is backed by yen bank deposits and Japanese government bonds, and holders can redeem them for regular yen on demand. AZ-COM Maruwa Holdings plans to use JPYC to pay approximately 2,300 business partners and independent contractors for transportation work and outsourced services, primarily covering truck drivers and subcontractors. The company is also developing a dedicated wallet application and plans to link payments with delivery confirmation records, potentially executed through GPS tracking or smart contracts.

Their features include: 1:1 reserve backing of the underlying assets, held by licensed custodians; stock dividends distributed 1:1 in token form; support for synchronized mapping of corporate actions (such as stock splits); and the ability to use holdings as joint margin for unified accounts and USDT-margined contracts, allowing users to flexibly manage their funds while holding global equity assets.
Grayscale Research Director: ETH Issuance Mechanism Similar to "Fiscal and Monetary Policy", Core Controversy Lies in Security and Inflation Trade-off
Grayscale Research Director Zach Pandl stated in a post on platform X that Ethereum is like a "small country," while ETH has only one core "government function": protecting property rights and value exchange within the system. Unlike traditional countries that provide public services through taxation, Ethereum mainly relies on "seigniorage," i.e., issuing new ETH, to fund network security. Under this framework, stakers responsible for maintaining network security are equivalent to the group providing public services, receiving rewards through newly issued ETH. Therefore, Ethereum's staking mechanism and ETH issuance policy essentially constitute the network's fiscal policy and monetary policy simultaneously; more security guarantees usually mean stronger property rights protection, but at the cost of higher ETH issuance volume and potential other risks. Some community members believe that Ethereum's monetary and fiscal policy design should consider the security trade-offs brought by these key ratios, but the current mechanism has not yet fully incorporated these factors. Zach Pandl added that the above analogy may not be entirely accurate as it does not yet involve other important factors such as the ETH burn mechanism, MEV, governance, etc.; how the future ETH issuance policy will be adjusted remains to be seen based on community governance results.

Loss of approximately $130 million: Coldcard firmware vulnerability leads to the theft of around 2,000 BTC
Odaily News: Part of hardware wallet manufacturer Coldcard's firmware had a random number generation vulnerability in 2021, causing some mnemonic phrases generated by the devices to carry predictable risks. The vulnerability was only discovered years later, and by then approximately 5,200 addresses and around 2,000 BTC had been stolen, with losses totaling about $130 million. Following the incident, some investors turned to Wall Street custody products. U.S. spot Bitcoin ETFs saw net inflows of approximately $626 million within days of the event. ETF analyst Eric Balchunas noted that security incidents like this could further drive capital flows into ETFs. The Bitcoin core community continues to uphold the principle of self-custody. Casa co-founder Jameson Lopp said recent events should not weaken user confidence in self-custody, as third-party custody carries risks as well. Early Bitcoin Core developer Peter Todd stated that self-custody has a better long-term security track record than centralized institutions. Michael Tanguma, co-founder of Bitcoin custody platform Onramp, said both approaches have flaws: concentrating large amounts of assets in a single institution creates a "honey pot," while hardware wallets face risks related to supply chains, firmware, and random number generation. Michael Tanguma proposed a "multi-institution custody" approach, in which multiple regulated institutions each hold keys through a multi-signature mechanism, and any transaction requires joint signing by multiple institutions to reduce the risk of single points of failure. Critics argue that while multi-institution custody improves security, it also introduces permissioned management, which conflicts with the decentralized ideals Bitcoin originally pursued. As Bitcoin enters pension funds, trusts, and institutional asset allocation, the industry is seeking custody solutions suitable for long-term wealth management. How to strike a balance among security, decentralization, and usability remains a challenge facing the Bitcoin ecosystem.
德州数据中心审计收紧电力供给，Bernstein：现有比特币矿工及 AI 运营商价值提升
据 The Block 报道，德克萨斯州州长 Greg Abbott 本周一下令要求公用事业委员会（PUCT）及电网运营商 ERCOT 对州内所有在队列中的数据中心项目展开审计，ERCOT 随即暂停了原定本月公布结果的"Batch Zero"大型用电审批流程。目前数据中心申请占 ERCOT 474GW 互联队列的约 90%。 Bernstein 分析师在周二发布的客户报告中指出，此次监管审查将抑制投机性开发、压缩新增电力容量供给，从而提升已获批电力容量的稀缺价值，利好现有比特币矿企及 AI 运营商。报告点名 Cipher Digital（CIFR）、CleanSpark（CLSK）及 Core Scientific（CORZ）受审计影响较大，因其近期扩张计划依赖德州电网接入；而 Terawulf（WULF）因电力资产分布于肯塔基、马里兰及纽约等多州，抗风险能力较强；Riot Platforms（RIOT）和 IREN 则因已在 ERCOT 拥有大规模获批运营资产而受益。
Glassnode: Bitcoin Enters Late-Stage Bear Market Compression Phase, No Genuine Demand Signal Yet
Odaily News, Glassnode reports that Bitcoin is currently trading between a median realized price of approximately $63,000 and a short-term holder cost basis of approximately $68,700. Spot trading volumes have dropped to their lowest levels since 2019, with the market in an extremely quiet state of compression. Core inflation fell to 2.5% in July and stock markets hit new highs, yet Bitcoin has shown almost no reaction or has even weakened, indicating a clear absence of demand. Selling pressure is subsiding, with profitable supply approaching levels seen at previous bear market bottoms. The seller exhaustion indicator has hit cycle lows, and the adjusted SOPR has been rejected near the breakeven line nine times.Meanwhile, buyers continue to stay on the sidelines, with negligible net inflows into ETFs and Bitcoin still flowing into exchanges. Derivatives leverage has already been heavily skewed toward longs ahead of time, open interest remains relatively high compared to trading volume, and order book bid depth is thinning. Glassnode identifies key levels to watch at approximately $68,700 to the upside and $58,500 to the downside. Only a decisive break above the former, accompanied by a recovery in trading volumes and ETF inflows, would confirm market improvement. If the latter is lost, an accelerated decline is likely given thin buying support and crowded long positioning. Glassnode states that Bitcoin is currently in the late-stage bear market compression phase, and no genuine demand signal has yet emerged.

Bybit Releases Latest Options Weekly Report (08.03-08.10): NFP Major Surprise as Labor Market Cools, XAUT Leads Strongly, Bybit Newly Lists HYPE Options
Last week, major assets closed higher across the board: July Non-Farm Payrolls -23k severely dampened rate hike expectations, the USD broke below 100, and Gold and Crypto benefited in tandem. BTC/ETH ETF weekly net inflows were $853M/$245M, the third-largest institutional buying week of the year. Core risk this week: 8/12 CPI (08:30 ET), determining the direction of September rate hike expectations. Strategy advances on three fronts: Sell ETH weekly expiry $1,800 P (annualized ~15-20%), Sell HYPE 1D $52 P (annualized ~70%, newly listed on Bybit), Sell XAUT 1D $4,360 C (annualized ~30-60%). All three positions must be reduced to safe levels before CPI.

Bitcoin BIP-110 Nears Block 961,632, Miner Signal Support Rate Only 2.45%
Odaily News: Bitcoin's BIP-110 will enter the enforcement phase after block 961,632, where nodes will reject blocks that do not signal support. Monitoring page data shows that among the 1,674 blocks counted in the current cycle, only 41 blocks support BIP-110, putting the miner signal support rate at 2.45%. BIP-110, officially named "Reduced Data Temporary Softfork," plans to tighten certain data rules in Bitcoin transactions within approximately one year, restricting the size of certain data elements used by Ordinals inscriptions and multiple token protocols. The proposal is primarily distributed through Bitcoin Knots, and Bitcoin Core has not adopted it. Major mining pools such as Foundry, Antpool, F2pool, and Viabtc have not issued support signals. If BIP-110 nodes execute as planned, the network could see two transaction histories, with the majority of miners and Bitcoin Core users expected to continue using the existing rules. Australian Bitcoin exchange Hardblock stated that BIP-110 activation is expected around August 7-8 and may temporarily suspend buying, selling, deposits, and withdrawals. Lightning Network tools and analytics provider Amboss has warned of a fork risk in early August, and Australian Bitcoin exchange Bitaroo plans to freeze deposits and withdrawals as the mandatory signaling deadline approaches.
Texas Pauses Approvals for ERCOT-Related Data Centers; Bitcoin Miners with Approved Power Contracts Likely Unaffected
Odaily News – Texas Governor Greg Abbott on Monday directed the Texas Public Utility Commission and the Electric Reliability Council of Texas (ERCOT) to audit all data centers seeking to connect to the state's power grid, and paused approvals for ERCOT-related data center projects. The audit timeline has not been disclosed. Bernstein analysts stated that most Bitcoin mining firms operating in Texas have already signed approved power capacity contracts, and their operations are not expected to be affected by the approval pause. They believe the audit will curb speculative data center pipelines, making real sites with development history more valuable. The analysts noted that Cipher Digital, Core Scientific, and CleanSpark's Texas operations may become more vulnerable to public opposition to data center expansion during future ERCOT approval processes to convert pipeline assets into grid-connected power capacity. IREN and Riot Platforms' Texas mining operations have already received full approval from the ERCOT grid.
BIP-110 Supporters Propose Restarting Minority Chain with BLAKE2b, Replay Attack Concerns Raised
Odaily News: BIP-110 supporters are discussing a hard fork to change the stalled minority chain's mining algorithm from SHA-256d to BLAKE2b. Transaction history before the fork remains shared by both chains. If transaction and signature rules remain consistent, the same transaction could be replayed on the other chain, creating a replay attack.BIP-110's peak miner support was approximately 2.53%. After the consensus rules took effect on August 8, the minority chain produced only two consecutive blocks before stalling, while the Bitcoin main chain continued operating and widening the block height gap. The BIP-110 proposal was subsequently marked as closed, and supporters shifted focus to discussing the BLAKE2b proof-of-work scheme.Bitcoin Knots plans to add a new signature hash option, but RDTS will still maintain compatibility with Bitcoin Core's existing signature hash types. Regular transactions may continue to be valid on both chains. Users will need to use the new option and rely on wallets or hardware signing firmware that support it to achieve asset separation.Luke Dashjr stated on August 18 that Bitcoin should bear the responsibility for replay protection, calling it "Spamcoin." If the BLAKE2b fork proceeds around September 1, exchanges, wallets, and holders will need to distinguish between cross-chain transactions and chain-specific transactions. (Bitcoin.com News)

COLDCARD vulnerability may have originated from compiler bypass handling
Odaily News: Bitcoin News posted on X platform that a new technical analysis by Core-Lightning developer ddustin shows that the 2021 COLDCARD vulnerability may have originated when developers attempted to connect the wallet using Python code, MicroPython's C code, and the STM32 hardware random number generator. The custom code appears to have conflicted with MicroPython's existing implementation, potentially triggering a compiler error. Evidence suggests that developers subsequently set MICROPY_HW_ENABLE_RNG to 0, allowing the firmware to compile successfully. This change led to unintended consequences: when users created new wallets, the firmware no longer used the hardware random number generator, instead falling back to MicroPython's weaker Yasmarang software random number generator. The commit message left by the developers was only "runs." The analysis states that this serves as a reminder to developers not to release security-critical code they do not fully understand, especially when it protects billions of dollars in Bitcoin.
Bitcoin Core Developer Claims to Have Reproduced COLDCARD MK3 Vulnerability, MK2/MK3 Devices May Be Affected
: Bitcoin News posted on X platform, stating that Bitcoin Core developer instagibbs claimed to have successfully reproduced the reported COLDCARD vulnerability on a newly initialized COLDCARD MK3 device, using only the number of button presses during the setup process, and said, "Sorry, now is the time to panic." He believes the issue affects MK2/MK3 devices, but stated that it is currently unable to confirm whether the MK4 has the vulnerability. Developer Antoine Poinsot stated that the key difference is that the MK4 uses a hardware random number generator to provide entropy for the seed and actually utilizes the microcontroller's True Random Number Generator (TRNG), while the MK3 does not. The proof of concept and mnemonic phrase verification are still under review.
CertiK Report: Wrench Attacks Surge Nearly 12x in Losses, “Operational Security” Becomes New Core of Prevention
Odaily Odaily News, July 22nd - Web3 security firm CertiK released its "H1 2026 Wrench Attack Report." The report indicates that a total of 52 publicly verified wrench attacks were recorded globally in the first half of 2026, a year-over-year increase of 33.3%; related losses amounted to approximately $124 million, an increase of about 11.8 times compared to the same period last year.The report notes that attackers are shifting from exploiting technical vulnerabilities to targeting asset holders and their real-world social networks. Home invasion incidents increased from 1 case in H1 2025 to 20 cases, accounting for 41% of the total incidents in the period. Europe has become a high-incidence area for attacks, with 33 cases occurring in France alone, representing 63.5% of the global total.CertiK stated that as real-world risks become a significant challenge for digital asset security, enterprises and high-net-worth individuals need to establish more comprehensive protection systems. CertiK has launched operational security services to help identify exposure risks related to identity, family, residence, and travel routes. Simultaneously, through the CertiK Security Workspace, it correlates off-chain intelligence, on-chain transactions, and AML risk signals to support institutions in tracking and analyzing cybercrime activities. Furthermore, CertiK is strengthening cooperation with international law enforcement agencies such as Interpol and Europol, providing technical support for cross-border attack investigations and security policy research.

AI programming platform Replit announces adoption of OpenAI's low-cost model to lower the barrier to programming
: AI programming platform Replit has launched a new feature called Free Mode, powered by OpenAI's latest low-cost model GPT-5.6 Luna, aimed at reducing the cost for users to access AI programming tools and enhancing the value for paid subscribers.Replit stated that Free Mode is currently available to Core and Pro subscribers, corresponding to the $20/month and $100/month plans, respectively. This mode will serve as the default experience, allowing users to prioritize the low-cost model for chat, brainstorming, and simple programming tasks. When a task requires stronger reasoning capabilities, Replit Agent will automatically switch to a higher-performance model.Michele Catasta, Head of AI at Replit, said that the launch of Free Mode is made possible by OpenAI significantly cutting the cost of the GPT-5.6 Luna model. At the end of July, OpenAI reduced the API price of this model by approximately 80%, achieving cost reduction through improved model efficiency rather than relying on additional computing resources.

Google Releases Pixel Watch 5: Minor Hardware Upgrades, AI and Health Features Become Core Selling Points
According to The Verge, Google has officially released the Pixel Watch 5, priced at $399, up $50 from the previous generation. Hardware updates are limited, featuring only a faster Qualcomm processor, a slightly increased battery capacity, and new Satin Pyrite colorway and Steph Curry Special Edition. The biggest highlight of this generation lies in the software front: Gemini adds an offline mode, supporting basic operations such as setting timers and launching apps in offline environments (though response speed is significantly slower in offline state). Meanwhile, Gemini will more proactively provide contextual suggestions; for example, when receiving a text message inquiring about the schedule, users can directly access Google Calendar from the wrist. Additionally, the watch face adds real-time information icons, capable of instantly displaying timers, Uber estimated arrival times, and fitness data.

Plan B: Scarcity, Not Short-Term Price Fluctuation, Is the Core of Bitcoin's Long-Term Value
Bitcoin analyst Plan B stated on the X platform that the core of Bitcoin's long-term value lies in scarcity, not short-term price fluctuations.Plan B believes that many people focus on Bitcoin's price charts, while the S2F model he uses focuses on the degree of asset scarcity. This model measures scarcity through "existing supply ÷ annual new production," where the S2F for gold is approximately 60. Due to Bitcoin's fixed total supply of 21 million coins and its predictable issuance schedule, its S2F is currently around 120 and continues to rise over time.The Bitcoin halving mechanism is an important driver of the S2F model. Approximately every four years, the Bitcoin network reduces the block reward by half, decreasing new supply and roughly doubling the S2F level, making it the core supply-side event observed by the model.Plan B emphasized that the S2F and its upgraded version, the S2FX model, predict long-term average value rather than precisely forecasting market tops or bottoms. Bitcoin's price typically fluctuates around the model's estimated value, and investors should focus on multi-year cycle averages rather than single-day price highs. Additionally, Plan B believes that as scarcity increases, Bitcoin is undergoing different stages of development, including proof of concept, payment network, "digital gold"/store of value asset, and institutional-grade financial asset. Each increase in scarcity could bring new market narratives and capital inflows.However, Plan B also reiterated that "all models are wrong, but some are useful." He stated that the S2F model is merely a tool for long-term understanding of Bitcoin's scarcity, not a trading signal or a "crystal ball" for price prediction. Although the model has withstood major events such as the COVID-19 pandemic and China's mining ban, it still has limitations.

BIP-110 Supporters Propose Restarting Minority Chain with BLAKE2b, Replay Attack Concerns Raised
Odaily News: BIP-110 supporters are discussing a hard fork to change the stalled minority chain's mining algorithm from SHA-256d to BLAKE2b. Transaction history before the fork remains shared by both chains. If transaction and signature rules remain consistent, the same transaction could be replayed on the other chain, creating a replay attack.BIP-110's peak miner support was approximately 2.53%. After the consensus rules took effect on August 8, the minority chain produced only two consecutive blocks before stalling, while the Bitcoin main chain continued operating and widening the block height gap. The BIP-110 proposal was subsequently marked as closed, and supporters shifted focus to discussing the BLAKE2b proof-of-work scheme.Bitcoin Knots plans to add a new signature hash option, but RDTS will still maintain compatibility with Bitcoin Core's existing signature hash types. Regular transactions may continue to be valid on both chains. Users will need to use the new option and rely on wallets or hardware signing firmware that support it to achieve asset separation.Luke Dashjr stated on August 18 that Bitcoin should bear the responsibility for replay protection, calling it "Spamcoin." If the BLAKE2b fork proceeds around September 1, exchanges, wallets, and holders will need to distinguish between cross-chain transactions and chain-specific transactions. (Bitcoin.com News)
AI programming platform Replit announces adoption of OpenAI's low-cost model to lower the barrier to programming
: AI programming platform Replit has launched a new feature called Free Mode, powered by OpenAI's latest low-cost model GPT-5.6 Luna, aimed at reducing the cost for users to access AI programming tools and enhancing the value for paid subscribers.Replit stated that Free Mode is currently available to Core and Pro subscribers, corresponding to the $20/month and $100/month plans, respectively. This mode will serve as the default experience, allowing users to prioritize the low-cost model for chat, brainstorming, and simple programming tasks. When a task requires stronger reasoning capabilities, Replit Agent will automatically switch to a higher-performance model.Michele Catasta, Head of AI at Replit, said that the launch of Free Mode is made possible by OpenAI significantly cutting the cost of the GPT-5.6 Luna model. At the end of July, OpenAI reduced the API price of this model by approximately 80%, achieving cost reduction through improved model efficiency rather than relying on additional computing resources.

Alliance Co-founder: Decentralized Social Graph Isn't the Core Value That Attracts Users to Farcaster—Social Trading Could Be the Direction
Odaily News: Imran, co-founder of Alliance, stated on X that Farcaster is a valuable infrastructure and application experiment, but a decentralized social graph alone is insufficient to attract users away from traditional social platforms like X.He believes the direction truly worth focusing on is social trading—integrating new token discovery, speculative trading, and PnL reputation into a native product loop, a model that is currently difficult for traditional social platforms like X and Instagram to replicate. Additionally, Imran summarized this product evolution path as MetaMask → Phantom → Farcaster → Moonshot → Vector → Fomo/Pump, noting that each generation of products further reveals what crypto users genuinely care about.Previously, Neynar co-founder Rish Mukherji posted on X that the team has initiated a process to find new ownership or operational teams for Farcaster, Clanker, and Neynar.
Grayscale Research Director: ETH Issuance Mechanism Similar to "Fiscal and Monetary Policy", Core Controversy Lies in Security and Inflation Trade-off
Grayscale Research Director Zach Pandl stated in a post on platform X that Ethereum is like a "small country," while ETH has only one core "government function": protecting property rights and value exchange within the system. Unlike traditional countries that provide public services through taxation, Ethereum mainly relies on "seigniorage," i.e., issuing new ETH, to fund network security. Under this framework, stakers responsible for maintaining network security are equivalent to the group providing public services, receiving rewards through newly issued ETH. Therefore, Ethereum's staking mechanism and ETH issuance policy essentially constitute the network's fiscal policy and monetary policy simultaneously; more security guarantees usually mean stronger property rights protection, but at the cost of higher ETH issuance volume and potential other risks. Some community members believe that Ethereum's monetary and fiscal policy design should consider the security trade-offs brought by these key ratios, but the current mechanism has not yet fully incorporated these factors. Zach Pandl added that the above analogy may not be entirely accurate as it does not yet involve other important factors such as the ETH burn mechanism, MEV, governance, etc.; how the future ETH issuance policy will be adjusted remains to be seen based on community governance results.
