President Xi Jinping took a phone call from Brazilian President Luiz Inácio Lula da Silva. President Xi noted that China is ready to strengthen strategic coordination with Brazil at bilateral and multilateral levels, and sustain the sound momentum of building a community with a shared future. The two sides should join hands to advance high-quality development of greater BRICS cooperation and write a new chapter of uniting for strength within the Global South.

SAMSUNG’S $200B BROADCOM DEAL IS BIGGER THAN A MEMORY SUPPLY CONTRACT. 📊 Samsung Electronics $005930 and Broadcom $AVGO have agreed to pursue more than $200B of semiconductor cooperation through 2030, covering HBM, advanced foundry manufacturing and packaging. Reuters separately confirmed the $200B Samsung–Broadcom portion of the wider Korea–US semiconductor agreements. The headline number is huge, but the strategic shift matters more. Samsung is trying to move from being viewed as a component supplier to becoming a full-stack AI semiconductor partner: Memory → Foundry → Advanced Packaging The reported scope includes HBM4 and HBM4E for Broadcom’s AI accelerators, sub-2nm foundry processes for key chip products, and integrated support from design optimization through packaging and mass production. That matters because Broadcom is one of the central players in custom AI accelerators and high-speed data-center networking. If this MOU converts into real production orders, Samsung would capture more value from each AI chip—not only memory revenue, but also manufacturing and packaging economics. For the Korean market, Samsung is the clearest direct beneficiary. Equipment, materials and packaging names may follow, but only after capacity expansion, supplier participation and actual purchase volumes are confirmed. I would not treat the entire $200B headline as booked revenue yet. This is still an MOU. The real revaluation depends on: → Final contract volumes → Product and process allocation → Production timing → Pricing and margins → Whether orders translate into utilization and earnings The headline creates expectations. Execution is what creates the rerating. $005930 $AVGO For reference only. This is not investment advice. Avoid excessive leverage, do not chase sharp moves and maintain strict risk management.

Safe AI won't come from competition alone, says Matt White, global CTO of AI at The Linux Foundation, at @AMD's Advancing AI event. It will require global cooperation and openness.

President Droupadi Murmu was warmly received by President Nicușor Dan of Romania at Cotroceni Palace, Bucharest. She was accorded a ceremonial welcome and guard of honour. The two leaders held productive and forward-looking discussions covering the major dimensions of our bilateral partnership. They also exchanged perspectives on regional and global developments, and on multilateral cooperation. Three MoUs for bilateral cooperation in the field of science & technology, sports and establishment of Chair of Indian Studies at University of Bucharest were signed on the occasion.

A day of clear outcomes, strong partnerships and a shared vision for healthier futures. Day 3 of the 16th BRICS Health Ministerial Meeting brought together BRICS Member States and Official Partner Countries to strengthen global health cooperation. The unanimous adoption of the BRICS Health Ministers’ Declaration, bilateral meetings, the Healthy Lifestyle Walkathon and India’s healthcare innovations highlighted a shared commitment to resilient, innovative, inclusive and sustainable health systems. #BRICS2026# #BRICSIndia2026# #IndiaBRICSChairship#

Nonce-Generation Vulnerability in the Zilliqa Ledger App: A critical vulnerability has been identified in the Zilliqa Ledger application affecting the generation of Schnorr signatures for native (non-EVM) Zilliqa transactions. The vulnerability causes signatures to be generated with a predictably weakened ephemeral nonces, from which an attacker can recover the signer’s private key using only publicly available on-chain data. Protective measures are already in place to prevent further loss, and a coordinated remediation plan is being finalised. Users who have signed native Zilliqa transactions with a Ledger device should await official guidance before taking any action. Impact: The vulnerability affects private keys used to sign native Zilliqa transactions with a Ledger device. Any account that has broadcast approximately five or more native transactions signed through the Zilliqa Ledger app should be considered compromised. Its private key can be reconstructed from signatures already recorded on-chain, regardless of any subsequent software update. The issue is confined to the Ledger app’s native signing path. EVM transactions are unaffected. Zilliqa software development kits, including zilliqa-js, gozilliqa-sdk and pyzil, generate nonces correctly and are not affected. Root cause: Zilliqa native transactions are authenticated using EC-Schnorr signatures over secp256k1. Each signature requires a fresh, uniformly random 256-bit ephemeral nonce, (k). The secrecy and full-width randomness of (k) are essential, as any systematic bias can allow the private key to be recovered. The signing routine generated 40 bytes of randomness and reduced them modulo the curve order, correctly producing a uniform 256-bit value. However, when copying this value into the nonce buffer, the code copied the wrong 32 bytes of the 40-byte output. This retained the eight zero-padding bytes introduced by the reduction and discarded eight bytes of entropy. As a result, the most significant 64 bits of every generated nonce were fixed at zero, meaning (k < 2^{192}). A nonce with 64 known bits leaks information about the private key with each signature. With five or more affected signatures, the private key can be recovered in seconds using commodity hardware by solving the resulting Hidden Number Problem through lattice reduction - a well-documented technique for attacking biased-nonce signatures. Because the affected transactions are permanently recorded on-chain, this exposure cannot be reversed by updating the signing application. The affected keys must be retired. Timeline 2019-2026: The defect was present in every released version of the Zilliqa Ledger app across all supported devices. 19 July 2026: On-chain activity consistent with active exploitation was observed. 21 July 2026: The root cause was isolated to the app’s nonce-handling code and confirmed by reproducing the issue against on-chain signatures. Ongoing: A corrected version of the app is being prepared in coordination with Ledger. Release details will be announced separately. Remediation: As soon as the issue was identified, native (non-EVM) transactions were suspended as a protective measure. This has halted further draining of affected accounts while a solution is prepared. Affected accounts cannot be secured through an ordinary transfer. Because their private keys can be derived from data already recorded on-chain, an attacker with access to the same key could attempt to front-run a legitimate transfer as soon as transactions resume. Advising users simply to move their funds would therefore be ineffective and potentially unsafe. A corrected build of the Ledger app has been prepared, restoring full-width nonce generation and preventing further weakened signatures from being produced. However, this does not protect keys that have already been used to sign affected transactions. Those keys must ultimately be retired. A coordinated remediation plan to secure affected balances is being finalised and will be published separately. Until then, users who have signed native Zilliqa transactions with a Ledger device should take no independent action and should rely solely on official Zilliqa channels for instructions. Users who hold or transact with ZIL exclusively through EVM-compatible tooling are not affected. Acknowledgments: @kucoincom played a key role in pinpointing the root cause in the Zilliqa Ledger app nonce generation, recovered affected private keys from publicly available on-chain signatures, and confirmed ongoing exploitation. KuCoin’s timely reporting and responsible collaboration enabled rapid protective measures, helping safeguard users, ecosystem participants, and the broader Zilliqa ecosystem while the remediation plan was being developed. We sincerely appreciate the KuCoin team’s professionalism, technical expertise, and cooperation throughout this process.
