Check Point Research ha rivelato che il gruppo di minaccia persistente avanzata (APT) della Corea del Nord, KONNI, ha preso di mira gli sviluppatori di blockchain in Giappone, Australia e India. Gli hacker stanno utilizzando backdoor PowerShell generate da IA.
Secondo rapporti pubblicati il 21 gennaio 2026, l'attacco inizia quando KONNI utilizza Discord per offrire un link che invita gli sviluppatori a scaricare un file ZIP. Questo archivio contiene elementi che avviano un processo di infezione a più fasi sul computer della vittima.
Il file ZIP include un collegamento di Windows e un file PDF apparentemente autentico. Il collegamento di Windows avvia script che lanciano uno script PowerShell in memoria, generano attività pianificate e estraggono altri file. Questo script si connette quindi a server sotto il controllo degli attaccanti, creando una backdoor permanente sul sistema compromesso.

The Tezos protocol has been successfully upgraded, following an on-chain governance process with broad participation from bakers (validators) and community members. 
Developed by Nomadic Labs, Trilitech, and Functori, Tallinn is the 20th protocol upgrade, marking 20 evolutions of the Tezos blockchain, proposed, adopted, and seamlessly activated by the protocol itself.
“Adapting to market demand 20 times over 7 years without network disruptions, and in a fully decentralized way, is undeniable proof of Tezos’ reliability and future-proof design,” said Yann Régis-Gianas, Head of Engineering at Nomadic Labs. ”
The Tallinn upgrade shortens Tezos Layer-1 block time to 6 seconds, reducing latency and speeding up finality on the network’s censorship-resistant settlement layer. This pairs naturally with Etherlink, Tezos’ EVM-compatible Layer-2, which already confirms transactions in under 50 milliseconds, now backed by Layer-1 finality in two blocks, or 12 seconds.
Tallinn also enables all bakers (network validators) to attest to every block, instead of a subset of bakers, which brings stronger security and more predictable staking rewards. This is achieved through the use of BLS cryptographic signatures, which aggregate hundreds of signatures into just one per block. By lightening the load on nodes, it also opens the door to further block time reductions.
Finally, Tallinn introduces an ‘Address Indexing Registry’ that can improve storage efficiency by up to 100x for apps using the Michelson runtime. It is done by eliminating redundant address data, and apps adopting this feature will benefit from lower costs and higher potential throughput. 
“Based on inputs from Tezos builders, our development team is excited to be able to offer such drastic improvements for enterprise-scale apps, large NFT ledgers, and other setups storing many addresses,” said Yann Régis-Gianas, Head of Engineering at Nomadic Labs. 
Since launching in 2018, the Tezos blockchain has continued to evolve seamlessly through protocol upgrades, with each activation introducing a series of features designed to improve the overall experience of using and building on the network. Tallinn is another forkless step forward in making Tezos faster, more secure, and optimized for enterprise use, with no compromise on decentralization, and further proof of the network’s ability to quickly adapt to user needs and ensure longevity through continuous innovation and optimization.

Man mano che pagamenti, finanza e infrastruttura blockchain continuano a convergere, sta prendendo forma un nuovo paradigma di circolazione del valore.

1. Da DeFi a PayFi: L'inevitabile evoluzione delle applicazioni blockchain
Nelle prime fasi dello sviluppo della blockchain, il focus dell'industria era ampiamente incentrato sui trasferimenti di asset e sui derivati finanziari.
DeFi (Finanza Decentralizzata) ha dimostrato che la blockchain può costruire sistemi finanziari senza intermediari.
Tuttavia, non ha risolto un problema più fondamentale: pagamenti e regolamenti quotidiani.

River, the first chain-abstraction stablecoin system designed to connect assets, liquidity, and yield across ecosystems, today announced $8 million in strategic investment from TRON DAO Ventures.
River will deploy its chain-abstraction stablecoin infrastructure and expand its integration across the TRON ecosystem, strengthening TRON’s position as a leading blockchain network for stablecoin activity.

River will enable cross-ecosystem assets and liquidity to enter the TRON ecosystem through its chain-abstraction stablecoin infrastructure. The integration will further accelerate the flow of cross-ecosystem liquidity into TRON, extending access to one of the world’s largest blockchain networks.
By abstracting underlying network complexity, users will be able to move assets across blockchain ecosystems without navigating individual chains, simplifying cross-chain participation and settlement.
The initiative aims to build a more unified and interoperable infrastructure to support activity across the TRON network.
As part of the initiative, satUSD will be introduced across several core protocols within the TRON ecosystem. It will be deployed in stablecoin liquidity pools alongside USDT and USDD on SUN, with price feeds provided by WinkLink, and will be made available on JustLend for lending and borrowing.
The integration will extend across a range of assets and dApps across the TRON ecosystem, including TRX, USDT, wBTC, BTT, JST, SUN, WIN, and select NFT use cases. River also plans to introduce a Smart Vault and an institutional-grade Prime Vault.
TRON is one of the most actively used public blockchain networks globally, processing approximately 56 percent of all retail-sized USDT transfers in the fourth quarter of 2025, the highest share among major blockchains.
According to Tether’s latest transparency report, the network currently hosts approximately $83.4 billion in USDT liquidity, reflecting its role as a primary blockchain infrastructure supporting stablecoin activity worldwide.
By combining River’s cross-ecosystem connectivity with TRON’s scalable blockchain infrastructure, the collaboration aims to support the development of a more integrated network for liquidity, yield, and asset deployment.
The initiative reflects a shared focus on strengthening blockchain infrastructure to support scalable settlement, cross-ecosystem liquidity, and institutional participation.

About Audi Revolut F1 Team
Audi Revolut F1 Team is the official factory team of Audi, as the brand enters the FIA Formula 1 World Championship for the first time in 2026. This project, in which Audi will create its own hybrid drive system (‘power unit’) developed in Germany, represents the ultimate expression of the manufacturer’s ‘Vorsprung durch Technik’ philosophy and embodies a long-term commitment to compete at the pinnacle of motorsport with the clear objective of challenging for world championships by 2030. Audi Revolut F1 Team is based in three locations: the power unit is developed by Audi Formula Racing GmbH at the Audi Competence Center Motorsport in Neuburg, Germany; the chassis is engineered and race operations are managed from the state-of-the-art facilities of Audi Motorsport AG in Hinwil, Switzerland; while the Audi Motorsport Technology Centre UK in Bicester, United Kingdom, provides a foothold in the heart of ‘Motorsport Valley’, with direct access to top F1 talent and key strategic partners. This integrated structure provides complete control over the project, embedding a culture of precision, innovation, and relentless performance. Audi’s entry is strategically timed to coincide with new Formula 1 regulations focused on increased electrification, as the electric share of the hybrid drive is raised to almost 50%, and the introduction of 100% sustainable fuels. The entry into Formula 1, one of the most important platforms in the world, serves as a high-tech catalyst for the entire Audi brand, acting as a global stage to demonstrate technological leadership and connect with new, diverse audiences by creating cultural impact that resonates far beyond the race track.

On Monday, U.S. Senators Cynthia Lummis and Ron Wyden introduced the Blockchain Regulatory Certainty Act. This bipartisan effort aims to exempt non-custodial blockchain developers and infrastructure providers from federal money transmitter regulations.
This law aims to encourage innovation in blockchain and follow federal guidelines. In addition, it seeks to make sure that non-custodial developers are not treated like banks or financial institutions under regulations.

Furthermore, the proposed bill states that developers who make software, manage distributed ledgers, or offer essential infrastructure without controlling users’ funds will not be considered money transmitters according to federal law.
Senator Lummis, the chair of the Senate Banking Digital Assets Subcommittee, highlighted that developers who simply write code and manage open-source systems have been subjected to unfair regulatory pressures. She said that calling them money transmitters doesn’t make sense because they don’t manage user funds, and this label hinders innovation.
Senator Wyden pointed out the constitutional issues with the current regulations. He argued that treating developers the same way as exchanges or brokers is not only a poor fit for technology but also violates Americans’ privacy and free speech rights. The law aims to create a clearer set of rules by matching federal standards with state laws. This will help boost the U.S. digital finance sector.

Currently, many blockchain developers are facing unclear rules. As a result, some move their innovations to other countries and create different regulations in various states. Recent legal actions against developers, like the prosecutions of Tornado Cash and Samourai Wallet, have caused worries in the crypto community.
In these situations, prosecutors argued successfully that managing and overseeing code could categorize developers as financial institutions, making them subject to the Bank Secrecy Act.

Il token NYC, una criptovaluta avviata dal precedente sindaco di New York City Eric Adams, ha registrato un forte calo di valore poco dopo il lancio sul mercato. All'inizio, il token era valutato a 730 milioni di dollari, ma è rapidamente calato del 80% circa, scendendo a circa 90 milioni di dollari in appena un'ora. Tuttavia, si è poi ripreso superando i 110 milioni di dollari.

Adams ha annunciato il token NYC in una conferenza stampa a Times Square, definendolo un "asset commemorativo" che celebra l'innovazione e la diversità di New York City. L'offerta totale del token è di un miliardo. Al lancio, 80 milioni saranno disponibili per il commercio, con piani per aumentare tale quantità fino a 300 milioni.
