Japan allocates more than $900 million to support chip startup Rapidus

Comparing news, the Japanese government will allocate an additional 150 billion yen (about 944 million US dollars) to support chip startup Rapidus and increase spending to compete with companies such as TSMC. Japan's Ministry of Economy, Trade and Industry will seek more funding for the Japanese OEM chip maker in the 2027 fiscal year budget, according to a source familiar with the matter. The government-backed joint venture was founded in 2022 with the goal of manufacturing cutting-edge 2-nanometer chips by 2027 and helping Japan reduce its dependence on TSMC. Policymakers see Rapidus' success and technological independence in AI, robotics, and quantum computing as critical to national security.

Grayscale: Zcash's privacy features may be just what is needed in the AI era, if the market share rises to 5% of value or a 9x increase

Comparing news, Grayscale released a Zcash research report stating that as the development of AI brings new methods of financial monitoring, the privacy characteristics of Zcash may become a necessary function in the AI era. Zcash blocks transactions through zero-knowledge proofs, hides the sender, receiver, and amount, and has cash-like privacy properties. Currently, Zcash blocks about 90% of the transaction volume, and the blocked supply is about 4.2 million ZEC (25% of the circulating supply). According to Grayscale, Zcash's market capitalization is around $8 billion, accounting for only 0.6% of its classified “monetary cryptoassets” sector (with a total market capitalization of $1.4 trillion). If this sector accounts for 5%, the value of ZEC will be 9 times what it is today. The report argues that the market's current valuation of Zcash reflects the assumption that “privacy will remain marginalized,” and that if investors ultimately believe privacy should receive a modest premium, the current valuation may be undervalued. In terms of risk, the report mentions long-term risks such as regulation and quantum computing, but believes that Zcash's shielding technology and selective disclosure tools provide a path for compliance.

SK Hynix ADR was hyped out of a 10% premium, and South Korean retail investors poured $4.5 billion into US stocks in July

Comparing news, Korean retail investors are shifting capital from the local stock market to the US market. According to data from the Korea Securities Depository, Korean investors made a net purchase of about 4.5 billion US dollars of US stocks in July, of which about US$8.4 billion went to SK Hynix's US listing on ADR, making it one of the largest net purchases of US securities by Korean investors. It is worth noting that Korean investors could have bought SK Hynix directly in the Korean market, but chose to buy its US ADR, causing the stock prices of the two places to clearly deviate. Currently, SK Hynix ADR has a 10% premium over local Korean stocks, and stocks listed in the US are more volatile. Owen Lamont, senior vice president of Acadian Asset Management, believes that this rare price difference may be a sign of excessive market speculation or even a symptom of a bubble. The shift of South Korean retail investors to US stocks did not reduce their risk appetite, and AI, semiconductors, and highly leveraged products remain core bets. Of the 10 US stocks that Korean investors bought the most in July, 4 were leveraged products. Among them, the Direxion Daily Semiconductor Triple Longer ETF (SOXL) was the most popular. Meanwhile, the Korean stock market financing balance has dropped from about 37 trillion won at the end of June to about 27 trillion won at the beginning of August. Analysts pointed out that Korean retail investors may simply transfer high-risk AI transactions originally carried out in the local market to the US market rather than actually exit risky assets. The industry believes that the size of South Korea's capital is insufficient to change the overall trend of US stocks, but its centralized trading may further amplify price fluctuations in highly volatile assets where retail investors are highly concentrated, such as AI chips, quantum computing, and leveraged ETFs.

After eight years of investment, why did Ethereum abandon Poseidon?

Author: ChandlerZ, Foresight News Original title: After eight years of sharp turns, why did Ethereum suddenly abandon Poseidon? On August 13, Ethereum researcher Justin Drake wrote on X that the Ethereum Fund decided to abandon the SNARK-friendly hash algorithm Poseidon at the L1 layer and instead use traditional hash functions such as SHA2 or BLAKE2. Behind this decision is eight years of research, the accumulation of tens of millions of dollars, and a major revision to the post-quantum cryptography roadmap. Since its launch in 2019, Poseidon has been regarded as an ideal hashing scheme for applications such as zkRollup and zKVM. Its structure makes it cheaper and more efficient than traditional binary-based hash functions in SNARK circuits. But when post-quantum security became a hard requirement for Ethereum, Poseidon's limitations began to be exposed. Justin Drake said that this shift is due to groundbreaking SNARK design progress, that is, the performance of traditional hash functions in SNARK circuits is comparable to that of Poseidon, which was previously designed specifically for SNARK optimization. A single laptop can verify about 1 million traditional hash calls per second. According to the article, Poseidon has been the mainstream SNARK-friendly hashing scheme since its launch in 2019, providing security guarantees for applications such as zkRollup and zKVM. Justin Drake said that the plan shows that production-grade LeanVM is expected to be launched in 2027, the relevant deployment of the consensus layer, data layer and execution layer is expected to be completed in 2028, and the quantum team is also accelerating research related to the binary domain after the Ethereum Foundation. Why now? Traditional hashes have been difficult to enter SNARK for a long time, and the main obstacle comes from differences in computational languages. SHA2, BLAKE2s, and Keccak make extensive use of Boolean operations such as XOR and shift. Traditional SNARK usually processes arithmetic on large prime numbers, and simulating every bit operation can incur high constraint costs. Poseidon is designed directly around prime field arithmetic, with fewer constraints in exchange for higher proof speed. The cost is that the algorithm has a short history and requires continuous cryptographic analysis. The binary domain switches the underlying math to the smallest element domain containing only 0 and 1, and uses the binary domain extension to carry larger data. As a result, bit computation can directly enter the proof system. SNARK began to adapt to traditional hashes, and the technical focus changed from designing SNARK-friendly hashes to designing hash-friendly SNARKs. Binius, proposed by Jim Posen and Benjamin Diamond in 2023, shows the binary tower domain SNARK path. The Flock paper by Benedikt Bünz, Ron Rothblum, and William Wang was uploaded to arXiv on July 29, 2026. Its M4 Max benchmark is that a single core proves 82,000 times of BLAKE3 compression and 42,000 SHA- cycles per second With 256 compression and 30,000 Keccak replacements, the 10-core BLAKE3 has a throughput of over 660,000 times. According to Drake, the laptop can prove about 1 million traditional hash calls per second, which is about 100 times the cost of native CPU Boolean calculations; SNARK.fast reached 1.8 million BLAKE3 per second on M3 Max a few days ago. LeanVM in 2027, the 2028 three-tier deployment Another key reason for the abandonment of Poseidon is that the post-quantum security timeline is accelerating. “The Quantum Threat to Blockchains - 2026 Report” published by Project Eleven points out that the rapid development of quantum computers poses a serious threat to blockchain security. Once a “cryptographics-related quantum computer” (CRQC) appears, the Shor algorithm can quickly crack asymmetric cryptography such as ECDSA (used by Bitcoin and most public chains) and RSA. It is expected that Q-Day (quantum decryption day) may be between 2030 and 203...

Is Bitcoin still salvageable? Let the data do the talking

Author: Will Clemente (@WClemente) Compiled and collated by: BitPushNews Author Profile: Will Clemente worked as the chief analyst at Blockware Solutions in his early years, focusing on Bitcoin on-chain data (exchange fund flow, holder behavior, etc.). In 2021-2022, he co-founded Reflexivity Research with Anthony Pompliano to provide institutional-level on-chain and macro research, and later became a listed company DeFi Technologies acquisition. He then became a consultant and participated in STIX related work. X has nearly 800,000 fans. The analytical style is data-driven and easy to understand. It is one of the influential voices in the field of Bitcoin cycle judgment. Here is the text: Happy summer! I haven't written a long analytical article on Bitcoin in a while. In this post, I'm going to do a thought review and share my thoughts on this asset class and some of my personal thoughts on how to deal with future trends. Last year, I generally focused my personal market attention on commodities, because it was clear at the time that there was an oversupply problem in the cryptocurrency sector, which made the market seem very heavy. At the same time, with the exception of Hyperliquid, lack of substantial innovation led to a lack of market interest — at least compared to the market activity we saw in other markets — making it difficult for demand to absorb all supply. I thought that late last year, when small-cap stocks soared and gold had just set off a sharp rise, Bitcoin had a window of good performance, but I was very disappointed when Bitcoin basically experienced a failed breakthrough (a few days before October 10). In January of this year, I further reduced my Bitcoin positions that I personally still hold because the market trend at the time was similar to the previous bear market we experienced in 2022. Frankly speaking, this hasn't been a fun year for those focused on Bitcoin and the cryptocurrency space. Although judging from the percentage decline, Bitcoin's retracement is much milder than in 2022, in many ways, one can argue that this bear market is even tougher than 2022. At least in 2022, you can clearly indicate the reason for the decline (rising interest rates, removal of leverage and fraud, FTX thunderstorm) and determine that “if these things are likely to change, and at the end of 2022, things are asymmetrically biased towards the impossibility of getting worse, then Bitcoin is probably a good long-term buying point here” — yet today, we don't see any similar situation, other than DaTS and quantum computing (which I'll talk about later), and what I think are some positive signs of recovery that I think are finally beginning to appear. Bitcoin ETFs hold 50 billion US dollars in assets and set a record for initial capital inflows, but they were surpassed by storage ETFs earlier this year. Major institutions have begun to introduce loan products. Gold performed extremely well last year, driven by central bank reserve demand. Fueled by the de-dollarization narrative, this should have been a time for Bitcoin to shine. Almost any individual or entity that wants to gain exposure to Bitcoin can do it, which makes it even more disappointing to see a net Bitcoin ETF outflow of $5 billion over the past year, while DRAM attracted $10 billion in capital inflows within a month. Network Health When we talk about the fundamentals of Bitcoin, we're clearly not talking about metrics in the traditional sense; we're focusing on the underlying state of the network itself. I'm not going to go through each data point one by one to list the data, but I think there are two main points that are really important. In an increasingly centralized world, in the context of a country-led economy and a country-influenced market, and the most centralized technological power brought by large technology companies, I do believe that decentralization is of great value. For those who don't know much about the details of Bitcoin, in addition to the miners we all know, there are also nodes. Nodes can be run by anyone and are responsible for enforcing rules and verifying the network, while miners provide security through extensive energy-backed computation. There are nodes all over the world, and there are probably many more that you can't easily track. The following list alone covers nearly 200 countries.

In the early stages of quantum attacks, untraceable wallets were stolen, and Tether minting keys may become high-value targets

Comparing the news, Christopher Smith, founder of blockchain startup Quantus, said that the first quantum attack may have been the result of a series of unexplained crypto wallet thefts rather than directly stealing Satoshi Nakamoto's sleeping bitcoin estimated to be worth around $63 billion. He pointed out that quantum computers that are powerful enough can derive private keys from public keys exposed on the chain, so attackers can transfer funds without invading wallets, devices, or exchange internal systems. In cases of theft from high-security agencies, the only evidence may be the absence of traces of intrusion. Smith said that the first targets of quantum attacks may be military systems and state secrets; in the blockchain space, stablecoin issuer Tether's minting keys may be more valuable. By managing wallets, attackers can mint tokens out of thin air and sell them before the issuer responds. Google has accelerated the post-quantum migration timeline to 2029; Smith believes the probability of quantum computers cracking modern cryptography around 2028 is “50-50.” Related blockchains have begun migrating to post-quantum signatures.

Starknet completes anti-quantum signature transfer tests and explores wallet upgrade paths without migration

In comparison, Starknet announced that it has completed the anti-quantum signature transfer test. A wallet account using the anti-quantum signature mechanism completed the actual transfer on the Starknet main network. The transaction fee is about 6 cents, and it can be queried through the block explorer. This account is currently an experimental, unaudited version, mainly for research testing. StarkWare said the transfer was due to the Starknet account model design. Unlike most blockchains that fix the signature algorithm at the protocol layer, each Starknet account is a smart contract and can independently define the accepted signature scheme, so users can upgrade their wallets from traditional elliptic curve signatures to quantum-resistant signatures without a hard fork, no need to migrate assets, or change addresses. StarkWare notes that most blockchains face quantum computing risks because wallet signatures and underlying verification systems rely on elliptic curve cryptography. Once large-scale quantum computers appear, running the Shor algorithm may break the relevant cryptographic systems. Currently, the Starknet ecosystem supports an anti-quantum signature scheme based on Falcon-512. The solution is in the post-NIST quantum cryptography standardization system, and related implementations have been promoted by the ecosystem team and organizations such as OpenZeppelin.

Jim Cramer Says He Will Clear Bitcoin, Fears Quantum Computing Threatens Its Security Within 3 Years

Comparing news, former hedge fund manager and CNBC presenter Jim Cramer said he plans to sell all of his BTC holdings due to concerns that quantum computing threatens Bitcoin's security. The statement stemmed from an interview with IBM Chairman and CEO Arvind Krishna, who said investors should be wary that quantum computing will challenge modern cryptography in the next 3 to 4 years. Cramer believes quantum computing could threaten the Bitcoin network in the near future. However, no one has yet independently confirmed how much BTC it holds or whether it has completed the sale. After its statement, Bitcoin was still trading normally around $63,764, and some market participants once again viewed their views as an inverse Cramer signal. Bitcoin uses an ECDSA signature mechanism based on the secp256k1 curve. Theoretically, a sufficiently powerful quantum computer can derive a private key from the public key using the Shor algorithm. The risk mainly focuses on addresses that have been exposed to public keys, including reused addresses, early wallet formats, and a short unconfirmed time window after the transaction was broadcast. Researchers estimate that around 6 million to 7 million BTC, accounting for about 30% of the supply, may be in this category. Google Quantum AI estimated in March of this year that it would take less than 500,000 physical qubits to crack the relevant cryptographic mechanism, which is about 20 times lower than previously predicted. However, current quantum systems usually only have hundreds to thousands of physical qubits, and the number of logical qubits with higher reliability is even smaller. Most researchers expect that quantum computers with real cryptographic cracking capabilities may appear by the 2030s or even 2040s, so Cramer's 3-year forecast is significantly earlier than most technology expectations.
