According to CoinDesk, the XRP Ledger activated a fix named fixCleanup3_4_0 at 22:52 Beijing time on November 4. This fix addressed a vulnerability: certain accounts that were originally only authorized to "burn" tokens issued by the issuer could, under specific conditions, also create new tokens. This vulnerability affected the network's permissioned delegation system, for example, stablecoin issuers could authorize payment processors to burn tokens when customers redeem them, but did not grant them the authority to create new tokens; under the old rules, accounts with limited burn permissions could mint tokens simultaneously.The vulnerability affected assets issued on the XRP Ledger, including stablecoins, but did not impact XRP itself, and there are currently no publicly confirmed exploitation cases. This fix also included accounting corrections for the planned lending system and Single Asset Vaults, as well as corrections related to automatic trading pool token recovery, permissioned transactions, and transaction signatures. The activation was completed after two consecutive weeks of support following an interruption in validator support in October.

The Cosmos ecosystem decentralized exchange Osmosis has burned 55.5 million OSMO from the community pool.

Solana Mobile posted on platform X that the SKR buyback and burn plan has been launched. This plan will operate from October 15, 2026, and has already burned a total of 1.2 million SKR. Solana Mobile will transfer part of its revenue to a dedicated buyback and burn wallet, purchasing SKR on the open market through a series of on-chain buy orders, and will burn the purchased SKR on-chain.Solana Mobile stated that the sources of funds include Solana Mobile validators, exchanges from the Seed Vault wallet, and USDC Earn Vault. Since the launch of Seeker, part of the revenue from these sources will be allocated for buybacks and burns. The buybacks and burns will not pay any returns to SKR holders or stakers, and staking rewards will remain unchanged. All buybacks and burns will be conducted on-chain.

The board of the Recall Foundation, a decentralized AI agent evaluation platform, announced that it will orderly liquidate the Recall Foundation in the short term, a decision made independently of Recall Labs. RECALL was launched in October 2025.Data from RootData shows that Recall has raised approximately $42 million in total funding. The board believes that continuing to develop the protocol is commercially unfeasible, and the announcement states that this decision was not caused by a hacking incident or security event.The foundation intends to transfer all RECALL it holds or controls to a designated empty address for destruction, expected to be 358,562,442 tokens, accounting for approximately 35.86% of the total supply of 1 billion tokens. After the destruction, the expected total supply will be 641,437,558 tokens. Holders will not receive any distributions, redemptions, or monetary compensation. Staked RECALL is not included in the destruction scope, and holders must un-stake and withdraw it themselves. From the date of the announcement, new un-staking applications will no longer have a 30-day cooling-off period.As of October 30, the foundation holds approximately $3.7 million in assets, intended to pay creditors and vendors about $3.45 million, liquidation costs of about $200,000, and reserve about $50,000 for contingencies. The foundation plans to voluntarily liquidate under Cayman law. On that day, new competitions and staking rewards will cease, and by November 30, the official application will switch to read-only mode, with final liquidation and destruction of remaining tokens expected to be completed in the first quarter of 2027.

On October 27, SUN announced the completion of the 52nd round of $SUN buyback and destruction, with a total of 7,232,977.17 SUN being repurchased and permanently destroyed. The funds came from a portion of the protocol revenue generated between July 25, 2026, and October 25.As of this round, the total amount of SUN destroyed has reached 685,780,165.49, of which SunSwap V2 has cumulatively destroyed 388,023,868.41, SunPump has cumulatively destroyed 285,879,914.81, and SunX has cumulatively destroyed 11,876,382.27.

According to a report by the Financial Associated Press, 2022 Fields Medal winner Hugo Duminil-Copin stated at the French Mathematical Society that his original research direction no longer exists. He said, "On Tuesday night, I cried, and my crying woke up my daughter. They (OpenAI) have destroyed my field of research." The report mentioned that at least 16 papers related to his long-term research interests were included in the results released by OpenAI earlier this month.The report noted that since April of this year, AI companies have frequently announced solutions to unsolved mathematical problems to showcase their model capabilities. Earlier this month, OpenAI released over 700 papers at once, claiming to have solved hundreds of previously unresolved mathematical problems. Stephane Mallat, a recipient of the 2025 Gold Medal from the French National Center for Scientific Research, stated that the emotional impact of AI achievements is significant, but society still needs mathematicians and opposes the notion that "mathematicians are no longer needed." Cedric Villani, the 2010 Fields Medal winner, remarked that in mathematics, the process of reaching conclusions is far more important than the conclusions themselves.Francois Charles, head of the mathematics department at the École Normale Supérieure in Paris, stated that AI is changing the pathways for young people entering the mathematics field and pursuing PhDs, and concerns about talent development and career progression are valid; regarding the research itself, he believes that AI may help solve problems that were previously difficult to tackle. The Simons Foundation announced last week a $15 million initiative to help mathematicians cope with the changes brought by AI, with funding contributed by OpenAI and Anthropic, aimed at supporting workshops to evaluate AI achievements and establish standards for AI usage.

Among them, 30% of LAPTOP tokens are linked to real-world prediction results: if the relevant predictions come true, the corresponding tokens will be destroyed; if the predictions are not realized, the tokens will be donated to charity.This destruction was triggered by predictions related to the Nobel Peace Prize and also includes all unclaimed airdrop tokens.

On October 19, WINkLink announced that the first round of the WIN buyback and burn plan, which will be launched in the third quarter of 2026, has been completed, with a total of 67,357,364,510 WIN (approximately 6.735736 billion) burned in this round.According to the plan, 100% of the revenue generated by WINkLink will be used for the WIN buyback, forming a continuous deflationary mechanism supported by protocol revenue. The details of this round of destruction and the on-chain transaction records can be publicly queried, and the execution process is transparent and verifiable. The implementation of the first round of buyback and burn marks a substantial step for WINkLink in optimizing token economics and building a long-term ecosystem, laying a foundation for the normalization of subsequent rounds.
