hot_img Samsung Electronics plans to repurpose the NRD-K R&D production line for wafer foundry use, aiming for mass production of 2nm base chips for HBM

According to South Korean media ZDNet Korea, Samsung Electronics is adjusting the original purpose of its NRD-K Line 2 at the Giheung campus from a research and development facility to a wafer foundry line, with the main target product being the 2nm base chips required for NVIDIA's HBM. This production line is expected to be operational in the second half of 2028, adopting a "Send-Fab" model, which involves receiving wafers from other mass production lines and performing specific processes.NRD-K is the most advanced composite research and development campus built by Samsung Electronics to seize future semiconductor technology, with a total investment of approximately 20 trillion won, planning for three production lines, of which the first line is scheduled to be completed by the end of 2024. This adjustment aims to proactively respond to the expansion of HBM demand driven by investments in AI infrastructure. Samsung plans to first apply the 2nm process to custom HBM and HBM5 to maintain performance advantages.Industry insiders point out that the scale of NRD-K Line 2 is relatively small, making it suitable for operation in the Send-Fab format. However, there are still about two years until the production line is operational, and the final purpose may be adjusted again based on market conditions. Samsung had previously considered using this production line for DRAM production, but after modifications to the relevant plans this month, DRAM capacity will be more concentrated in the Pyeongtaek campus. Equipment procurement orders have not yet been officially issued.

Harmony Protocol confirms the first round of issuance of 4 billion ONE and prepares to roll back

Harmony Protocol released an event update stating that an unauthorized ONE minting incident occurred. Investigations show that the attacker exploited a cross-shard receipt replay vulnerability, allowing processed cross-shard receipts to be executed multiple times, and minted ONE in empty blocks.The team is currently verifying two sets of impact data: early analysis indicates that the first round of minting involved 4 billion ONE, while the latest on-chain reconstruction shows that approximately 3.01 trillion ONE were issued to four attacker wallets through six forged cross-shard transactions. Harmony Protocol confirmed the first round of minting of 4 billion ONE, generated through two empty block accounting transactions that produced 1 billion and 3 billion ONE respectively, of which 2.8 billion ONE were subsequently transferred to other attacker addresses.The team has fixed the cross-shard receipt verification and pre-staking committee quorum verification vulnerabilities and deployed Mainnet v2026.1.1. Bridge services have been suspended, and Harmony Protocol is coordinating with validators, trading platforms, and LayerZero to freeze related funds, preparing to roll back the network to block 92,730,034 before the attack occurred. Currently, Shard 0 has been paused at block 92,753,555, and the official RPC may return a 502 error as a result.

153 stolen addresses contain 132.95 BTC, and researchers are still unable to reproduce the Coldcard attacker's seed

According to monitoring by Bitcoin News, new research published by @PraveenPerera shows that Coldcard attackers seem to first identify addresses with vulnerabilities, then sort them by the amount of Bitcoin held, starting to transfer in batches from the addresses with the highest holdings. The transfer software used was relatively crude.One address had 225 spendable UTXOs, and the attackers extracted exactly the latest 200, leaving the earliest 25, which included a UTXO worth 0.16 BTC. This aligns perfectly with the limitation of a blockchain API investigated by researchers, which defaults to returning 200 records, indicating that the attackers may have failed to load the next page of data. The software even spent a UTXO of 294 satoshis, reportedly increasing the transaction fee by about 2040 satoshis, with the spent amount significantly higher than the value of the UTXO itself.The authors of the study believe that the builders of this tool may have a better understanding of the account balance system than of the Bitcoin UTXO model. Although the attackers seem to have obtained the complete seed of the victims, at least 75 BTC still remain in other addresses derived from the same seed. The biggest suspicion currently is that among the 153 stolen addresses, there are still 132.95 BTC, and researchers have been unable to reproduce the seed behind these addresses, so it cannot be ruled out that the attackers obtained undisclosed private device data or candidate data.

Michael Saylor proposed the digital asset spectrum framework: BTC represents digital capital, and STRC represents digital credit

The founder of Strategy, Michael Saylor, proposed the concept of the "Digital Assets Monetary Spectrum," categorizing different types of digital assets based on volatility, potential returns, and trading functions.Saylor stated that the digital asset system can be divided into four levels: Bitcoin (BTC): Digital Capital (Digital Capital) STRC: Digital Credit (Digital Credit) SR-strcUSX: Digital Money (Digital Money) USDT: Digital Currency (Digital Currency).He believes that from left to right, asset volatility and potential returns gradually decrease, while stability and trading utility continuously increase. Saylor stated that Bitcoin is the "ultimate value storage asset," possessing high volatility, high potential returns, and the attributes of a digital asset that does not require third-party credit endorsement; whereas stablecoins are the "ultimate medium of exchange," emphasizing stability and payment functionality. In between the two, digital credit and digital currency serve as a bridge connecting capital and currency. Among them, STRC is defined by Saylor as "digital credit," characterized by relative stability, high fixed returns, and certain value storage attributes.He further stated that digital currency combines digital currency technology with digital capital economic attributes, possessing stability, earning capacity, trading convenience, and value storage functions. Saylor noted that digital capital belongs to bearer assets, while assets such as digital credit, digital currency, and digital cash are created and managed by digital financial companies, with their ownership layer corresponding to "Digital Equity." These components together form the future "Digital Finance Stack."
