Odaily News: Researcher Robin Linus has released the Bitcoin Poker protocol, expanding the unfinished poker interface that Satoshi Nakamoto left in Bitcoin's early code in 2008 into a runnable solution. The protocol supports two players in Texas Hold'em without a dealer, using Bitcoin's existing rules to handle gameplay and fund settlement.Bitcoin Poker generates card faces through secret information jointly provided by both parties, generating only the 9 cards needed per hand, and uses cryptographic commitments and zero-knowledge proofs to maintain fair dealing. The protocol can check for duplicate cards, and the probability of a randomly generated hand passing the check is approximately 48%, requiring an average of 2.08 attempts.The protocol pre-builds a transaction tree for possible game outcomes, with a reference configuration containing 56,132 logical nodes and approximately 8.4 MB of preparation data. Normal gameplay occurs off-chain, with transactions used only to handle disputes when cooperation breaks down.If one party refuses to continue, a timeout mechanism can settle the committed pot after a specified delay and return the departing party's unused balance, but cannot force players to reveal their cards. The design requires no modifications to Bitcoin's consensus rules, supports only two participants, and still requires independent security review. (Bitcoin.com News)

According to CoinPost, Japan’s Liberal Democratic Party (LDP) Digital Society Promotion Headquarters’ “Next-Generation AI & On-Chain Finance Vision Project Team” released a policy proposal on May 19, advocating the integration of AI and blockchain to automate and enable 24/7 operation of decision-making, financing, and asset management—and designating finance as the “18th Growth Investment Sector.” Specific measures proposed in the document include: advancing tokenization of demand deposits at the Bank of Japan (including wholesale CBDC), with conceptual frameworks to be finalized by year-end; joint issuance of a stablecoin by Japan’s three major banks, targeting the launch of live operations by March next year; and promoting on-chain tokenization of real-world assets (RWAs), such as accounts receivable and real estate. At the international cooperation level, the proposal calls for establishing an “AI & On-Chain Finance Asia Policy Dialogue Framework” and advancing cross-border settlements using yen-denominated stablecoins, thereby realizing the “Global SC Corridor Vision.”
