first_img IBM will connect Digital Asset Haven to the Swift shared ledger, supporting tokenized deposit transactions

IBM announced that customers of its digital asset management platform IBM Digital Asset Haven can now connect to permissioned blockchain networks, including the blockchain-based shared ledger from Swift. A new beta version of the ISO 20022 message adapter allows financial institutions to initiate tokenized deposit transactions through this ledger using standard payment messages. IBM stated that financial institutions participating in Swift-related programs have tested tokenized deposits on this ledger using Digital Asset Haven. The ledger supports tokenized deposits issued by banks, enabling participating IBM clients to transfer digital assets around the clock, with final settlement still completed through existing systems.Swift first announced this ledger at Sibos 2025, based on a prototype developed in collaboration with Consensys, with over 40 financial institutions involved in its design, 17 of which are participating in the tokenized deposit pilot. Swift currently connects over 12,500 financial institutions across more than 200 markets worldwide. The aforementioned message adapter allows banks to continue using existing payment message formats and operational processes without adopting blockchain-specific workflows.IBM is also expanding Digital Asset Haven to a localized deployment beta version, which can be installed on IBM Z and IBM LinuxONE in the client's own data center for managing digital assets such as stablecoins and tokenized deposits, without relying on public cloud infrastructure. IBM stated that the platform and key management layer are fully retained within the client's own environment, with keys protected by IBM Crypto Express hardware security modules.

first_img StarkWare stated that the cost of quantum-safe Bitcoin transactions has decreased to 67 USD, a reduction of approximately 79%

StarkWare stated in an update on September 23 that the estimated GPU computing cost for preparing a quantum secure Bitcoin (QSB) transaction has dropped to below $67, a decrease of about 79% compared to the approximately $320 computing expenditure for the first similar mainnet transaction in August. According to StarkWare, the first QSB transaction was packaged and confirmed on August 26, with the engineering work completed by Tomer Giladi, and submitted directly through MARA's Slipstream service. The preparation process consumed about 3100 GPU hours, utilized around 100 GPUs, and incurred a computing cost of approximately $320, excluding Bitcoin network transaction fees.This cost reduction resulted from the quantum secure Bitcoin optimization challenge initiated on September 16 by StarkWare, Yukon Research, and Eigen Labs. The challenge invited developers, researchers, and AI agents to optimize transaction construction software, ultimately resulting in 62 adopted improvements across two computational tasks required to prepare a QSB transaction, with benchmark tests showing an estimated computing cost reduction of about 79%. The relevant dashboard currently indicates that the estimated cost has further decreased to $66.The QSB proposal was released by StarkWare researcher Avihu Levy in April, introducing hash-based quantum attack protection for transactions without altering Bitcoin's consensus rules. Due to limited cost, complexity, and applicability, he described it at the time as an emergency measure while continuing to advocate for adjustments at the protocol level.

X-Agent Hackathon Emerges: The Prototype of Agent Economy - AI Begins to Independently Accept Orders, Refuse Transactions, and Purchase Models

The ongoing X-Agent AI MCP Hackathon has received nearly 40 projects, with some public works turning work decisions, capital management, and inter-machine trading into runnable products. X-Agent introduces three cases: BountyProof checks whether tasks are open, claimed, have relevant submissions, and the authenticity of rewards before the Agent accepts GitHub bounty tasks, with the core question being "Is this work worth doing?"Abstain empowers the Agent with the "do not trade" capability, returning execution, abandonment, or no trade based on preset rules before order execution. sumplus helps the Agent choose suitable model service solutions based on task context, output scale, model capability, and invocation costs, making the Agent an autonomous buyer of models, computing power, data, and API services.The three projects correspond to the foundational economic behaviors of the Agent: accepting work, utilizing funds, and purchasing services, pointing to work, capital, and trading primitives. X-Agent believes that a true Agent economy requires a complete cycle of "building, deploying, operating, discovering, invoking, paying, earning revenue, and distributing," positioning itself as the application layer of the Agent economy. This hackathon is still in the review stage, and the mentioned projects are only for public case reference, not representing shortlisted or award results.

first_img The Zcash community overwhelmingly voted to accelerate transactions and maintain Bitcoin-style halving

Zcash holders voted overwhelmingly to support speeding up transaction times while retaining the Bitcoin-like halving mechanism. This governance vote was for Zcash's next major network upgrade, NU7, with nearly 2.4 million ZEC participating in the vote, accounting for about two-thirds of the approximately 3.6 million eligible ZEC at the time of the snapshot. The results were calculated based on ZEC weight, with each eligible ZEC representing one vote.Among them, 99.9% of participating ZEC supported reducing the block time from 75 seconds to 25 seconds, 98.9% supported retaining the Bitcoin-like halving mechanism, 96.6% supported postponing the fee reissuance of the Network Sustainability Mechanism (NSM) until February 20231, and 99.3% supported launching NU7 as soon as possible, giving up any unrealized features before the deadline of September 30.This vote was limited to holders of ZEC in Zcash's latest privacy transaction pool, Ironwood. The ballots were encrypted and split into 16 parts for counting, making it impossible for validators to reconstruct the specific holders' votes and balances. Previously, a sentiment survey in February for NU7 only attracted 7.25% of circulating ZEC to participate. The voting results themselves will not directly change the network; the relevant features still need to be implemented, tested, and included in the final upgrade.
