pos

Proof of Stake (PoS) is a blockchain consensus mechanism that determines the accounting rights and reward distribution of nodes based on the amount and duration of token holdings. Compared to Proof of Work (PoW), PoS reduces energy consumption and enhances the scalability and security of the network. Token holders participate in network governance and transaction verification by staking tokens, earning block rewards and transaction fees. The PoS mechanism is widely used in blockchain projects such as Ethereum 2.0 and Cardano, promoting the development of green blockchain.

first_img Jito's JTX plans to launch a mobile app this fall, with the possibility of integrating perpetual contracts in winter

During an interview with The Starting Block at the Digital Asset Summit 2026 Asia, Brian Smith, the president of Jito Foundation, the parent company of the Solana ecosystem trading platform JTX, stated that JTX plans to launch stock trading features within the next two weeks and will release a native mobile app later this fall. The integration of perpetual contracts "may take until later this winter." He mentioned that the team is currently focusing on differentiating the spot trading features.JTX launched in July this year, supporting spot trading for cbBTC, SOL, HYPE, and meme coins, while also offering tokenized stocks and ETFs. The platform charges a fee for each transaction, with 80% of the revenue allocated to Jito DAO for the buyback and destruction of JTO tokens, and 20% distributed to referrers. Smith did not disclose the trading volume since the launch but emphasized the speed of product iteration, stating that the team has two full-time data scientists mining on-chain data to develop in-app discovery features.Smith positioned JTX as a "permissionless Robinhood" for Solana, emphasizing longer holding periods and competitive rates, and noted that other Solana applications tend to focus on early meme coin trading. Regarding perpetual contracts, he acknowledged that Solana "has a lot of work to do" and affirmed Hyperliquid's role in pushing centralized exchange traders on-chain, while stating that Solana is the "king" in the spot trading space.

first_img The U.S. Department of Justice cites the Bitcoin Fog ruling to oppose Roman Storm's motion for acquittal

U.S. federal prosecutors cited the appellate ruling related to the cryptocurrency mixer Bitcoin Fog as a supplementary basis against the not guilty motion of Tornado Cash developer Roman Storm. In documents submitted on Monday, the prosecution referenced the September 25 ruling by the appellate court that upheld the conviction and sentencing of Bitcoin Fog operator Roman Sterlingov. The District of Columbia Circuit Court found that Washington, D.C. had jurisdiction over all four charges: the money laundering charge was based on undercover agents completing Bitcoin Fog transactions in its D.C. office, while the unlicensed money transmission charge was supported by sufficient evidence showing that Bitcoin Fog had served clients in the area.The prosecution stated that the ruling "directly supports" its position in the Storm case, arguing that Tornado Cash's activities in Manhattan were sufficient to establish jurisdiction in the Southern District of New York for the conspiracy charges of money laundering and unlicensed money transmission against Storm, citing the testimony of Shakeeb Ahmed, who claimed to have used Tornado Cash in a Manhattan apartment. Judge Katherine Polk Failla has heard the arguments for the not guilty motion in April 2026 but has yet to rule. In August 2025, the jury found Storm guilty of conspiracy to operate an unlicensed money transmission business, but deadlocked on the charges of money laundering and conspiracy to evade sanctions; Storm submitted a post-trial not guilty motion in September 2025, arguing that the prosecution failed to prove he intended to assist criminals in abusing Tornado Cash.

U.S. CFTC: The latest proposed rule notice aims to establish a framework for the cryptocurrency spot market using existing authority

According to crypto journalist Eleanor Terrett, the latest Advance Notice of Proposed Rulemaking (ANPRM) released by the U.S. Commodity Futures Trading Commission (CFTC) attempts to utilize its existing authority to establish a market structure framework for spot trading in the crypto space. This framework will be built upon the existing DCM, DCO, and FCM registrations and create a new category called "crypto asset market."A significant difference from the Clarity Act is that the CFTC proposal is exploring a voluntary federal exchange registration pathway: spot exchanges that do not offer leverage can choose not to join this framework and continue to hold state money transmission licenses. Former CFTC Chairman Giancarlo stated that this provides exchanges with a "clear, voluntary single federal rulebook pathway" when customers trade using borrowed funds, and noted that the CFTC is acting within the authority granted by Congress in 2010, supported by court rulings recognizing assets like Bitcoin as commodities.Several lawyers have stated that this ANPRM is a "clever" or "creative" interpretation of Section 2(c)(2)(D) of the Commodity Exchange Act, potentially covering retail crypto spot trading that offers leverage, margin, or financing, even if customers do not actually use leverage. The proposal also addresses "actual delivery" under Section 2(c)(2)(D), seemingly focusing on whether customers own/control the assets rather than merely relying on the book records of a pooled account. However, the proposal still leaves significant questions regarding customer asset bankruptcy protection. Comments must be submitted within 60 days after the proposal is published in the Federal Register.
