first_img Matter Labs open-sources Prividium permission engine, German central bank tests self-hosted deployment

On September 8, the ZKsync development team Matter Labs announced that it has open-sourced the permission engine of its privacy blockchain platform Prividium for financial institutions under the Apache 2 license. This engine is responsible for managing roles and access permissions on the chain, determining who can read and write data. After the open-sourcing, institutions can run the permissioned chain in their own environment based on the public code without signing commercial agreements, and can independently inspect, run, and modify the core code, reducing reliance on a single vendor.The Deutsche Bundesbank became the first institution to test and deploy the open-source permission engine in its own infrastructure. Matter Labs stated that both parties will continue to collaborate on platform design and testing. Prividium achieves privacy by keeping transaction data within the institution, only recording zero-knowledge proofs that the ledger has been correctly updated on Ethereum or other compatible chains. Previously, the core of ZKsync OS, Atlas sequencer, Airbender prover, interoperability contracts, and block explorer and monitoring components have been open-sourced.Matter Labs CEO Alex Gluchowski stated that feedback from regulators indicated that relying solely on commercialized core components leads to unacceptable single vendor dependency, and the ability to run, inspect, and modify the code independently is a prerequisite for adoption. He also pointed out that this open-sourcing does not change the role of the ZK token, only adjusting which parts of the Prividium software are public code and which remain commercial products. Connectors such as management consoles, user access tools, and core banking system integrations remain paid products.

first_img Taurus Lianchuang: Banks need to build a three-layer infrastructure to access the Swift blockchain ledger

Lamine Brahimi, co-founder and managing partner of the cryptocurrency custody and tokenization company Taurus, stated in an interview with CoinDesk that banks need to meet three conditions to access the newly launched blockchain ledger by Swift: a proprietary permissioned chain that interacts with the Swift ledger, wallet capabilities, and tokenization and smart contract capabilities to integrate Swift's smart contracts.He pointed out that this means the Swift ledger is not a replacement for banks' internal systems, but rather acts as an orchestration layer, helping institutions achieve cross-border, round-the-clock transfers of tokenized deposits, with final settlement still completed through existing arrangements. Banks still need to hold and manage tokenized deposits, digital asset wallets, and related smart contracts themselves. In July, Swift announced that 17 banks were preparing for real-time transactions of tokenized deposits; in August, HSBC and Standard Chartered completed the first real-time interbank transaction, followed by DBS and Citibank completing weekend cross-border USD payments, reducing settlement time from a maximum of two business days to just a few minutes.Brahimi stated that additional infrastructure should not be seen as a flaw in Swift's design; the ledger is still an early product but provides banks with a choice between existing payment channels and tokenized deposits that can circulate around the clock. Taurus announced in August that it had completed Swift integration, providing the aforementioned three layers of capability through a single platform. He added that tokenized deposits were used very little before Swift's announcement, primarily adopted by larger global banks like JPMorgan. The Swift model retains deposits on the banks' balance sheets, distinguishing it from stablecoins issued outside the banking system.

U.S. Senate Investigation: USDT is a key liquidity channel for Iran's shadow banking, Gulf VASP faces higher sanction risks

A report from the U.S. Senate Permanent Subcommittee on Investigations (PSI) identifies stablecoins, particularly USDT, as a key liquidity channel supporting Iran's shadow banking system. Licensed virtual asset service providers (VASP) in the Gulf Cooperation Council (GCC) region face heightened sanctions compliance pressure and need to enhance wallet ownership identification and counterparty assessment.Soham Jethani, a partner at the law firm Septten, stated that merchants settling crypto assets into local fiat currency do not necessarily avoid sanctions risks. Liability may involve designated entities, the provision of funds or economic resources, and asset handling within the transaction chain, potentially arising before the final settlement by banks. Jethani pointed out that the name of the stablecoin or the currency in which it is priced does not determine legal ownership; specific rights depend on contractual arrangements and actual payment processes.Globally circulating stablecoins may also pose secondary sanctions risks, as indirect or historical wallet associations do not automatically constitute violations and must be assessed in conjunction with applicable regulations, transaction participants, and specific facts. In regulated markets like the UAE, licensed exchange wallets are continuously monitored, and related funds can be frozen before consumption settlements, with merchants also required to complete KYC. Regulated VASPs handling deposits and withdrawals bear the responsibility for counterparty and sanctions risk assessment and corresponding controls.

first_img Google released the Nano Banana 2.1 image model, with the developer call price being about half of the previous generation

Google released its latest image generation and editing model, Nano Banana 2.1, on October 6, and it has been launched in the Gemini app, AI mode of Google Search, Google Ads, as well as developer tools like Google AI Studio, Flow, and Stitch. This model can generate images from text descriptions and edit existing photos.Google stated that this upgrade focuses on three aspects: visual design, mask-based editing (where only the marked area changes), and subject consistency, meaning that characters or objects retain their original features after multiple edits. In the overall preference test for text-to-image generation, Nano Banana 2.1 scored 1050 ELO points, higher than Nano Banana 2's 990 points and Nano Banana Pro's 935 points. The model can handle up to 14 reference images simultaneously, track 4 characters and 10 objects, and output up to 4K resolution with an aspect ratio of up to 8:1. Developers can also set the thinking time before generation and enable fact-checking based on Google Search and Google Image Search.When called through the Google Developer API, the standard 1K image is priced at $0.0336, about half of Nano Banana 2's $0.067; the 4K image is $0.0756, while the previous generation was $0.151, and bulk tasks can enjoy a 50% discount. The above performance data comes from Google's own testing.

first_img European Central Bank officials: Without a digital euro, tokenized platforms may become fragmented

European Central Bank Executive Board member Piero Cipollone stated during the MNI Connect Webcast that without a pan-European digital payment solution covering various daily transactions, the fragmentation risk between tokenization platforms may increase, thereby undermining Europe's "resilience and monetary sovereignty." He pointed out that the goal of the European Central Bank should be to create a digital euro that can be exchanged between banks and used for daily transactions.Cipollone emphasized, "Our goal is not to replace the role of banks." He stated that the digital euro will provide banks with the infrastructure needed to compete in the digital age and help banks expand the coverage and application scenarios of their own solutions.According to him, the European Central Bank has not yet decided whether to issue a digital euro but plans to complete the legislative process by the end of 2026. If the project advances, a 12-month pilot program will be launched in the second half of 2027, with a potential official issuance in 2029. The European Central Bank first proposed introducing a digital euro in October 2020 as a complementary digital payment option to cash. Critics argue that the central bank digital currency could give EU officials the means to monitor or even control residents' spending. Cipollone stated in September 2025 that the digital euro will ensure that all Europeans can use a free and widely accepted digital payment method at any time, even in the event of significant disruptions.
