According to The Information, OpenAI has recently started offering a new payment method to some major clients in the past few months, where clients only pay after the AI has actually completed the tasks.The scenarios that have been implemented so far include customer service, where companies can pay based on the actual customer service tasks completed by the AI, rather than simply billing by Token, usage volume, or number of seats. OpenAI has not disclosed specific clients, unit prices, or the criteria for determining "task completion," and has declined to comment on this. This is not a new package available to all companies; the current public pricing on the official website for Enterprise still primarily charges based on quotas and Tokens, so this results-based billing seems more like a contract negotiated separately for certain major clients.In January of this year, OpenAI CFO Sarah Friar suggested that future AI business models would adopt results-based billing. In July, OpenAI further stated that instead of focusing on the unit price per Token, it should be considered how much it actually costs for the AI to complete a task, and this line of thinking has now begun to enter real contracts.

According to CryptoSlate, Polygon Labs issued an urgent notice that Polygon PoS nodes remaining on the old versions of Bor or Heimdall have lost consensus after the activation of the Austin and Kyoto hard forks and need to upgrade to catch up with the network progress. Austin was activated at mainnet block 91,949,700, requiring Bor v2.1.0 or above; Kyoto was activated at height 51,533,000, requiring Heimdall v0.11.0 or above.Austin fixed two types of Bor resource exhaustion risks: L1 to L2 bridging state synchronization events not counted towards the gas limit could slow down block processing; the TxDependency field having no size limit could lead to peer node crashes. Kyoto addressed vulnerabilities such as deep nested message attacks, fee coin scanning, and checkpoint signature recovery. Both hard forks are pure binary upgrades, requiring no state migration, and non-forked nodes do not need to resynchronize. Operators of old clients should upgrade and restore synchronization under Polygon's guidance if necessary.

Ethereum developer kevaundray submitted the EIP-12188 proposal, suggesting to shorten the consensus layer block retention window to reduce storage pressure on nodes. The proposal is currently in the public review stage and has received support from some Ethereum client developers.Developer DApplion expressed support for the proposal, while Lighthouse client contributor michaelsproul believes that this adjustment will not significantly impact Lighthouse's operation. The proposal points out that as the demand for Ethereum historical data changes, reducing the retention time for historical blocks in the consensus layer can optimize node resource usage.It was mentioned in the discussion that historical data pruning in the execution layer may affect some long-running nodes' ability to provide old block data, but developers believe this will not threaten network security or the normal operation of nodes. Currently, EIP-12188 has not yet been merged and still requires further review and community discussion.

ChianCatcher news, Circle's Senior Director of Strategy and Policy for the EU, Patrick Hansen, pointed out in a tweet that among the approximately 23 authorized electronic money token (EMT) issuers in the EU, only 9 have been granted permission to provide crypto asset services (CASP). This means that only these 9 can offer custody and transfer services for the stablecoins they issue, while the remaining 14 can only mint or burn tokens directly to customer wallets and cannot hold or send stablecoins on behalf of customers. This greatly limits the range of services that issuers can provide.Hansen stated that Circle has obtained the necessary CASP approval through the MiCA Article 60 notification procedure to provide custody or payment services related to USDC and EURC for institutional clients. He expressed surprise that more EMT issuers have not taken this step. The 9 that can currently offer some crypto asset services include Circle, Société Générale - Forge, CACEIS Bank, Banking Circle, Bridge, Fiat Republic, Newrails, Blue EMI, and Stable Mint.
