Internet personality and actor Adam Conover has come under fire for promoting the Sam Altman-backed crypto project, World Chain. The project received backlash in several countries due to data privacy concerns. An Instagram reel posted on Conover’s official Instagram account showing the internet personality registering for a World ID on Sam Altman-backed crypto project World Chain (WLD) has sparked criticism and speculation online, particularly on Reddit forums. In a three-minute long video jointly posted on the World official account, Adam Conover explained to the viewer that he was paid by World project to come to a keynote event they were hosting in San Francisco. He claimed that he was there to ask questions about the product, not to endorse it. “So they do not want me to endorse it, they just want me to ask questions about it, skeptical questions and let you make up your own mind about it and hopefully help you understand what the hell it does,” said Conover in the video. Throughout the video he is seen interacting with the project’s iris-scanning orb and a representative, asking questions about the project and the reason why it was paying people $41 in WLD tokens to register themselves on the app. “There is so much you can do with this app, if you are into crypto. I am not into crypto. If you are, you might want to check it out. They also say that in the future, you will be able to log into Tinder and other services like that using World,” said Conover. “Let me know what you’re gonna do, are you gonna get yourself Orbed or not? It’s entirely up to you,” continued. You might also like:Tokenized matchmaking? Sam Altman’s World matches up with dating app giant Match Group Adam Conover’s not-so-skeptical approach to World Chain Although Adam Conover does emphasize that he is not endorsing the product, users on Reddit criticized him for seemingly promoting the product and its usage. Adam Conover is well-known on the internet for being the host of the half-hour truTV show Adam Ruins Everything, where he debunks commonly held beliefs through an investigative logical approach. Many found it ironic that Conover was now approaching the World project without much skepticism, a stark contrast to his internet personality which seemed to scrutinize things instead of buying into them so lightly. “Even in the crypto space, Worldcoin is well-known to be a huge invasion of privacy and absolutely predatory. Adam – someone who’s entire shtick is deep research on popular topics – has no reason to not have known what he was promoting. Really disappointing,” said one Reddit user. “And finally, with his work complete, Adam had ruined everything else, so he turned his power inward and ruined himself,” said another user. Some have also highlighted the fact that the part of the video where Adam Conover is supposedly scanning his eye on an Orb, it is only shown very briefly. This prompted some users to accuse him of not really trusting the technology himself, yet he encourages other people to do so. The World Network had previously been banned and scrutinized in countries like Indonesia, Brazil and Hong Kong over privacy concerns due to its iris-scanning verification. Most recently, Indonesia’s Ministry of Communication and Digital temporarily suspended the platform on May 5 in light of complaints about suspicious activities related to the platform. The project has declared that it would allow users to delete their unique iris code permanently, effectively “un-verifying” their World IDs. It has also clarified that the verification data stays on the user’s device and is not shared to any third-parties.

多年来，以太坊用户一直因 Gas 费用不足而苦苦挣扎，交易失败。MetaMask 的新 Gas Station 通过在交换过程中支付费用来消除这一麻烦。 2 月 5 日，MetaMask 推出了“Gas Station”新功能，旨在解决以太坊 (ETH) 生态系统中最令人沮丧的障碍之一——Gas 费不足导致交易无法进行。 没有 ETH 来支付 gas 费？没问题。⛽️您现在可以使用您交换的代币支付 gas 费用。pic.twitter.com/rBNW3ymL65– MetaMask.eth 🦊🫰 (@MetaMask) 2025 年 2 月 4 日 由于网络费用必须以 ETH 支付，余额不足的用户经常会陷入困境，被迫经过耗时的过程，从交易所购买 ETH，然后将其转移到钱包中，然后才能继续。 借助其新的 Gas Station 功能，用户现在可以完成代币交换，而无需为 gas 维护单独的 ETH 余额。相反，交易费直接包含在交换报价中，从而消除了最后一刻 ETH 充值的需要，并使流程更加顺畅。 该功能目前已在以太坊主网的 MetaMask 浏览器扩展上线，并计划很快推出移动版本。 它支持多种资产的兑换，包括 Tether (USDT)、USD Coin (USDC)、Dai (DAI)、ETH、Wrapped Ethereum (wETH)、Wrapped Bitcoin (wBTC)、Wrapped Staked Ethereum (wstETH) 和 Wrapped Solana (wSOL)。用户只需确保其兑换价值足以支付 gas 费用即可。 MetaMask 的更新正值以太坊本身经历重大变革之际。验证者最近批准提高网络的 gas 限制，将其从 3000 万提高到计划的最高 3600 万 gas 单位。 Gas 限制决定了单个区块中可以处理的计算工作量，从而有效地设置了可包含的交易数量。 当限制过低且网络需求较高时，由于用户争夺区块空间，费用会激增。增加 gas 限制可以让更多交易容纳在每个区块中，从而提高网络效率并缓解拥堵。 根据链上数据，截至 2 月 5 日，平均 Gas 限额已攀升至 3550 万单位。以太坊上一次做出这样的改变是在 2021 年，当时将 Gas 限额翻倍，从 1500 万增加到 3000 万。 然而，这次最新的增长尤其引人注目，因为这是自以太坊过渡到权益证明以来的首次增长，标志着网络合并后发展的一大步。

CME Solana 期货产品的需求可能表明未来投资者对跟踪山寨币的 ETF 的兴趣。 K33 研究主管 Vetle Lunde 和高级分析师 David Zimmerman 写道，与芝加哥商品交易所的比特币 (BTC) 和以太坊 (ETH) 期货产品相比，CME Solana (SOL) 期货首次亮相交易活动乏善可陈。 CME SOL 期货于 3 月 17 日推出，交易量仅为 1230 万美元，未平仓合约仅为 780 万美元。相反，CME 比特币期货在 2017 年 12 月推出当天的交易量为 1.027 亿美元。 该交易所的以太坊期货第一天的交易量也达到了 3100 万美元，未平仓合约为 2090 万美元，超过了 CEM SOL 期货第一天的成交量。 你可能还喜欢：“白人锁链”：索拉纳的反觉醒广告引发社区强烈反对 尽管 Lunde 和 Zimmerman 指出 CME Solana 期货是在一个不确定的市场推出的，但分析师推测，交易数据可能表明机构和投资者对山寨币的需求不足，尤其是在以太坊之外。 报告推测，如果美国证券交易委员会批准这些产品，现货 Solana 交易所交易基金可能会受到投资者的冷遇。截至 3 月 18 日，至少有六家美国发行人（包括 VanEck、21Shares、Bitwise、Canary Capital、Grayscale Investments 和 Franklin Templeton）已向美国证券交易委员会提交上市现货 SOL ETF 股票的申请。 阅读更多：Xapo Bank 开设 100 万美元比特币支持的信用额度
