According to Cointelegraph, Block CEO and Twitter co-founder Jack Dorsey has introduced the beta version of Bitchat, a decentralized peer-to-peer messaging service that operates entirely over Bluetooth. Over the weekend, Dorsey shared his experience learning about Bluetooth mesh networks, relays, store and forward models, and message encryption as he announced Bitchat on X. The system, described as having 'IRC vibes,' is reminiscent of early web-based messaging systems from the late 1990s.Bitchat is a decentralized messaging application that functions over Bluetooth Low Energy (BLE) mesh networks, as detailed in Dorsey's white paper. It offers ephemeral, encrypted communication without relying on internet infrastructure, making it resilient to network outages and censorship. The network is fully decentralized, with no central servers, accounts, email addresses, or phone numbers required for registration. Messages exist only in device memory by default and are not stored on a central database, ensuring end-to-end encryption for added security.Unlike current popular messaging applications like WhatsApp and Messenger, which are operated by centralized, profit-driven corporations such as Meta, Bitchat provides a decentralized alternative. The mesh networking feature allows for automatic multi-hop message relaying, and users can set up room-based chats with hashtag-named group chats and optional password protection. A 'store-and-forward' system caches messages for offline peers for set time periods, enhancing the service's resilience.Each device in the Bitchat network acts as both a client and a peripheral, creating a self-organizing mesh where messages can hop between devices to reach distant peers. The system operates within a 30-meter Bluetooth range, with bridge nodes connecting separate clusters. Messages are encrypted based on their type—private, room, or broadcast—and large messages are fragmented into smaller 500-byte chunks. Future plans include enabling messaging over WiFi to increase bandwidth for larger messages.Bitchat's potential use cases include conferences, protests, disaster areas, or any scenario where internet infrastructure is unavailable, unreliable, or untrusted. The white paper concludes that Bitchat demonstrates the feasibility of secure, private messaging without centralized infrastructure. By combining Bluetooth mesh networking, end-to-end encryption, and privacy-preserving protocols, Bitchat offers resilient communication that functions anywhere people gather, regardless of internet availability. Dorsey, who previously served as CEO of Twitter and founded the decentralized social messaging platform Bluesky in 2019, left the Bluesky board in May 2024 without explanation.

According to PANews, a Canadian woman, Raelene Vandenbosch, has filed a lawsuit against Rogers Communications and Match Transact, alleging security failures that led to a SIM card hijacking attack in 2011. This incident resulted in the loss of 12.58 bitcoins, valued at $392,700 at the time, now worth approximately $1.36 million. The lawsuit claims that an employee at a Montreal-authorized mobile counter provided database access to a hacker posing as a telecom technician, allowing the transfer of Vandenbosch's phone number. The attacker subsequently accessed her Ledger and Shakepay cryptocurrency wallets. The plaintiff accuses the defendants of inadequate anti-fraud measures and excessive access to sensitive user information by counter staff.The British Columbia Supreme Court has ruled that the main aspects of the case should proceed to arbitration. However, the request for a "public acknowledgment of fault" will continue in court due to its public interest implications. The defendants have not admitted to the allegations and insist that the matter should be resolved through arbitration as per the user agreement.

According to PANews, Ethereum co-founder Vitalik Buterin has raised concerns about the risks associated with digital identity, even when wrapped in zero-knowledge (ZK) proofs. In his article, Buterin acknowledges that ZK-wrapping addresses many significant issues but highlights that risks remain, particularly those unrelated to biometrics. Most of these risks, such as privacy breaches, susceptibility to coercion, and errors, stem from attempts to maintain the 'one person, one identity' principle.Buterin contrasts this with the use of 'proof of wealth' as an anti-sybil attack measure, which he argues is insufficient for many use cases. He suggests that an ideal theoretical solution lies between these two extremes. However, achieving this balance in practice is challenging. Instead, Buterin advocates for a 'plural identity' approach as the best practical solution. This approach can be explicit, such as those based on social graphs, or implicit, involving various types of zero-knowledge proofs, none of which can dominate the market entirely.

According to PANews, the Near community has introduced a proposal aimed at improving the NEAR token economy by reducing the maximum inflation rate from 5% to 2.5%, while maintaining flexibility for future adjustments. If transaction fees are burned at approximately 0.1%, the actual inflation rate could decrease to 2.4%. The proposal also suggests lowering staking yields or incentivizing token holders to participate in decentralized finance (DeFi). The current fixed annual inflation rate of 5% has led to an increase in circulating tokens, equity dilution, and token devaluation due to minimal transaction fee burning.However, the proposal currently has a support rate of only 7.42%, with 36 days and 22 hours remaining until the voting period concludes. Opponents argue that reducing validator incentives by 50% would render their nodes unprofitable, potentially decreasing the number of validators and stakers. They also question the strong correlation between inflation rates and price performance.
