Part 5 of Cointelegraph Research’s Bitcoin covenant series examines how MATT and OP_CHECKCONTRACTVERIFY (OP_CCV) could let Bitcoin contracts carry state across transactions. According to Cointelegraph, MATT, or Merkleize All The Things, is a framework for stateful contracts and scalable fraud proofs, allowing contract information to be updated and passed forward as transactions occur. Standard Bitcoin scripts evaluate each transaction independently and do not retain information from earlier executions. Existing covenant designs can represent state through a finite set of addresses and transactions, but this approach does not provide an elegant way to perform numerical logic. MATT instead allows data committed to an output to be computed when it is spent and embedded in the next output, enabling a new state to be derived dynamically. Its proposed OP_CCV implementation builds on Taproot, whose output key can commit to additional data. MATT uses that mechanism to commit to contract state alongside the spending conditions, with the blockchain checking that each transition is valid rather than encoding all computation directly in script. OP_CCV allows a script to check that a Taproot input or output key commits to specified state data, then require an updated state to be committed to a designated next output. Its modes determine how the input’s bitcoin value is handled: default assigns the full amount to the checked output, deduct assigns the output amount while leaving a remainder available for other outputs, and ignore checks the script and data commitment without restricting the amount. Since default and deduct preserve value, separate inputs can cover transaction fees. Combined with OP_CAT, which enables byte concatenation in Script, OP_CCV could verify Merkle proofs, update a state-tree root and enforce that the next output commits to the new root. That could support fraud-proof systems where computation runs off-chain and only a disputed step is checked on-chain, without BitVM’s reliance on Lamport one-time signatures and presigned transaction graphs for state consistency. The combination could also enable more fully featured vaults; the article says OP_CCV alone can implement vaults, while OP_CCV and OP_CAT could provide functionality comparable to OP_VAULT. The series’ next article will examine application-specific proposals including OP_VAULT, OP_UNVAULT and OP_EVICT.

According to CNBC, Wednesday's analyst calls included Baird downgrading Nvidia to neutral from outperform, citing limited visibility that is delaying 2027 data center forecasts, supply constraints, possible softer demand and uncertainty about CEO tenure into 2027. Morgan Stanley maintained its overweight rating on Nvidia but removed the stock from its top ideas list and kept its 12-month price target unchanged. UBS reiterated Apple at neutral; its tracking across more than 30 geographies showed iPhone wait times fell week over week by two days for Pro models and seven days for Pro Max and Duo models. Goldman Sachs reiterated CoreWeave at buy after Tuesday's earnings. Deutsche Bank upgraded Unilever to buy from hold. Jefferies initiated coverage of Corning at buy with a $134 price target and Teradyne at buy with a $284 target; it also initiated FormFactor at buy with a $102 target, and Cognex and Littelfuse at buy. Other calls included Piper Sandler upgrading Alpha Tau Medical to overweight from neutral and initiating CareDx at overweight with a $100 target; TD Cowen initiating Mentari at buy; JPMorgan upgrading Republic Services to overweight from neutral with a Dec. 27 price target of $295 and Mercury Systems to overweight from neutral; and Jefferies initiating Zebra Technologies at buy with a $382 target, indicating 19% upside. Jefferies noted Zebra shares had fallen about 10% since 3Q as investors priced in memory-related margin pressure beyond its 21.6% 3Q adjusted EBITDA margin.

According to ChainCatcher citing Tether’s official announcement, Tether AI Research has released QVAC BotPsy, an open-weight model with 800 million parameters based on Alibaba’s Qwen3.5 architecture. It is designed for tool use and agent tasks on personal devices. Tether said BotPsy scored about twice as high as its base model on BFCL v4, ACEBench, τ-bench, and ToolSandbox, and outperformed the 2 billion-parameter Qwen3.5-2B-Think. The model can convert user requests into local tool calls, and developers can adapt and deploy its weights in their own systems.

According to Jin10, Nigeria averaged 1.69 million barrels per day of crude oil production in October, with a daily high of 1.79 million barrels and a low of 1.60 million, according to data released Wednesday by the Nigeria Upstream Petroleum Regulatory Commission (NUPRC). The commission said October marked Nigeria’s sixth consecutive month meeting its OPEC crude oil production quota. Excluding condensates, average crude oil production was 1.51 million barrels per day, slightly above OPEC’s quota of 1.50 million barrels per day. The commission said improved operating conditions, increased uptime at production facilities, and more efficient crude exports helped maintain production levels.

Anthropic PBC’s initial public offering has drawn orders for multiple times the shares available, according to people familiar with the matter, Bloomberg reported. Demand is accelerating for what could be the biggest first-time share sale ever.

Global server CPU shipments rose about 6% quarter over quarter and 31% year over year in the third quarter, well above the typical seasonal quarterly increase of about 3%. According to Sina Finance, UBS analyst Timothy Arcuri said Arm-based server CPUs' shipment share increased about 2.5 percentage points to 20.1%, while Intel's fell about 2.4 points to 51.5%; AMD's share was roughly unchanged at 28.4%. UBS said robust server demand and expanding AI applications supported shipments. As AI agent applications spread, each GPU will require more CPUs to handle tasks, which UBS said would expand the server CPU market over the long term. The bank estimates that, excluding supply constraints, the global CPU market could exceed $500 billion by 2030. However, memory supply bottlenecks, as AI processors require far more memory than traditional server chips, could bring the achievable market size closer to $210 billion. By contrast, PC CPU shipments fell 6% quarter over quarter in the third quarter, compared with a typical seasonal increase of about 1%. Intel gained shipment share in the PC processor market but lost revenue share in laptop processors. UBS expects rising memory prices and possible subsequent CPU price increases to further restrain PC demand, and lowered its forecast for 2027 global PC shipments from 2% growth to a 4% decline.

Swiss National Bank officials told the government on Wednesday that the bank was prepared to act in foreign exchange markets if necessary. According to Sina Finance, the annual meeting covered global and Swiss economic conditions, inflation trends, and monetary-policy challenges; the bank said it kept its policy rate at zero in September and was ready to act in foreign exchange markets to ensure appropriate monetary conditions. SNB President Martin Schlegel and supervisory committee head Barbara Janom Steiner attended. Officials said Swiss inflation remained low by international standards and within the bank’s 0%-2% target range despite accelerating in recent months.
