Charles Hoskinson's defense of hyperscalers at the Consensus event in Hong Kong in February has sparked discussions about decentralization risks in blockchain computing. According to NS3.AI, while advanced cryptography, multi-party computation (MPC), and confidential computing technologies help minimize data exposure, they do not eliminate the reliance on centralized cloud infrastructure. This ongoing dependence raises concerns about the true decentralization of blockchain systems, as the concentration of cloud services could pose risks to the integrity and resilience of these networks.#Blockchain #Decentralization #CloudComputing #Cryptography #MPC #ConfidentialComputing #DataSecurity #NetworkResilience #CentralizationRisks #CharlesHoskinson
🚀 Quantum Computing Poses Long-Term Challenge to Bitcoin Security
#QuantumComputing #Bitcoin #Cryptography #Blockchain #Cybersecurity #PostQuantum #DigitalAssets #BitcoinSecurity #BTC
Quantum computing presents a real threat to Bitcoin, but it is not an immediate crisis, according to Galaxy Digital's Head of Research, Alex Thorn. According to ChainCatcher, Thorn emphasized that investors should not misinterpret this long-term technological challenge as a reason to avoid Bitcoin immediately.
Thorn highlighted that the current risk is limited to specific addresses with exposed public keys, such as reused addresses, some custodial addresses, and assets in older address formats. Analysis by security firm Project Eleven indicates that approximately 7 million BTC are in this 'long-term exposure' category. However, they remain secure under the current quantum computing capabilities.
To address these concerns, developers have proposed several solutions. These include introducing new address types based on post-quantum cryptography, implementing a 'sandglass' mechanism to restrict spending from permanently exposed public key addresses, and a phased upgrade path to fundamentally reduce the broadcasting of transaction public keys.#QuantumComputing #Bitcoin #Cryptography #Blockchain #Cybersecurity #PostQuantum #DigitalAssets #BitcoinSecurity #BTC

#Ethereum #L2 #Linea #RISC-V #Architecture #Cryptography #zkC #ProofSystems #EthereumFoundation #Vortex #Arcane #FormalVerification #ETH
Ethereum Layer 2 project Linea has announced a shift to the RISC-V architecture, according to Foresight News. Alexandre Belling, a cryptography researcher at Linea, revealed the decision at Ethproofs, citing the need to rewrite constraint modules with each Ethereum hard fork as a major factor. This shift aims to reduce complexity and enhance performance.
RISC-V architecture offers 32 registers and approximately 40 instructions, providing a narrower tracking range for proof systems. This allows for real-time construction and immediate processing of proof fragments. Additionally, RISC-V features a narrower execution path and Type-1 compatibility, while maintaining zkC (constraint native language), Vortex, Arcane (proof/aggregation stack), and formal verification.
Linea noted that this move aligns closely with the Ethereum Foundation's ongoing RISC-V roadmap, with further technical details expected to be released in the coming weeks.#Ethereum #L2 #Linea #RISC-V #Architecture #Cryptography #zkC #ProofSystems #EthereumFoundation #Vortex #Arcane #FormalVerification #ETH
🚀 Google's Quantum AI Team Highlights Cryptography Vulnerability in Bitcoin and Ethereum

Google's Quantum AI team has released a new whitepaper indicating that breaking the cryptography used by Bitcoin and Ethereum may require fewer than 500,000 physical qubits, a figure significantly lower than the millions often cited in recent years. According to NS3.AI, Google researchers suggest that a prepared attacker could complete the final step in approximately nine minutes after a Bitcoin public key appears in a live transaction, compared to the roughly 10 minutes needed for confirmation.
The researchers also pointed out that Taproot, a Bitcoin upgrade, may increase exposure because it makes public keys visible by default. The paper estimates that approximately 6.9 million Bitcoin are stored in wallets with exposed public keys, potentially heightening vulnerability to quantum attacks.#Google #QuantumAI #Cryptography #Bitcoin #Ethereum #QuantumComputing #Taproot #Cybersecurity #Blockchain #CryptoSecurity #BTC #ETH

Google has announced its intention to complete the transition to post-quantum cryptography (PQC) by 2029. According to Foresight News, this move aims to address the potential threats posed by future quantum computers to current encryption standards.
Google highlighted that quantum computers could significantly undermine existing encryption methods, particularly affecting encryption and digital signatures. The threat to encryption is already evident through attacks such as 'store now, decrypt later,' while digital signatures face future risks that need to be addressed before the deployment of cryptography-related quantum computers (CRQC).
In response, Google has adjusted its threat model to prioritize the migration of authentication services to PQC. The company recommends that other engineering teams adopt similar strategies to safeguard against these emerging threats.#Google #PostQuantumCryptography #PQC #QuantumComputers #Encryption #DigitalSignatures #Cryptography #QuantumThreats #Authentication #Cybersecurity
🚀 Google’s Quantum Whitepaper Reignites Crypto Security Debate, Drawing Responses From CZ and Elon Musk
#QuantumComputing #CryptoSecurity #Bitcoin #Ethereum #Blockchain #Binance #CZ #ElonMusk #QuantumAttack #Cryptography #PostQuantumCrypto #BTC #ETH
Google’s latest research has revived debate over crypto security, suggesting quantum computers may need far fewer resources than previously thought to break the cryptography used by blockchains like Bitcoin and Ethereum. The study estimates that fewer than 500,000 physical qubits could crack the 256-bit elliptic curve cryptography widely used across the industry — a 20-fold drop from earlier estimates.The paper also describes a theoretical scenario in which a sufficiently advanced quantum computer could derive a Bitcoin private key in as little as nine minutes, creating the possibility of an “on-spend attack” in which an attacker exploits a public key exposed during a transaction and potentially steals funds within Bitcoin’s roughly 10-minute block window.Responding to the news, Binance co-founder and former CEO Changpeng Zhao (CZ) said there is “no need to panic,” arguing that crypto networks can ultimately upgrade to quantum-resistant algorithms. Still, he cautioned that implementation will be difficult in decentralized systems, with debates over standards, possible forks, wallet migrations for self-custody users, and the risk of new bugs during upgrades.CZ also raised the question of dormant coins, including Satoshi Nakamoto’s holdings, suggesting the industry may eventually need to consider how to keep such addresses from becoming targets for future attackers. His broader view remained optimistic: crypto, he said, will endure in a post-quantum world.Elon Musk offered a lighter take, joking: “On the plus side, if you forgot the password to your wallet, it will be accessible in the future.”#QuantumComputing #CryptoSecurity #Bitcoin #Ethereum #Blockchain #Binance #CZ #ElonMusk #QuantumAttack #Cryptography #PostQuantumCrypto #BTC #ETH

🚀 Challenges and Prospects of Encrypted Mempools in Ethereum
#Ethereum #EncryptedMempools #MEV #BlockchainPrivacy #ThresholdEncryption #Flashbots #CryptoEconomics #Decentralization #ProgrammablePrivacy #FHE #TEE #Cryptography #TransactionOrdering #EthCC #ETH
Jonathan Passerat-Palmbach, a senior research scientist at Flashbots and visiting scholar at Imperial College, discussed the academic evolution and practical limitations of encrypted mempools at the EthCC[9] conference. According to Foresight News, he highlighted the progression from early committee-based threshold encryption schemes to batched threshold encryption and the Beast-Mev scheme, which combines silent settings with batch decryption. Despite these developments, no current solution meets all the protocol-level requirements such as silent settings, non-interactive decryption, small keys, and small ciphertexts, preventing the cryptographic aspects of encrypted mempools from being directly integrated into the Ethereum protocol.
The economic implications pose a more significant challenge. The blind ordering mechanism used in encrypted mempools, where transactions are ordered while encrypted, leads to three main issues: searchers submitting numerous blind arbitrage bundles, resulting in on-chain spam; reduced MEV subsidies making geographically remote validators less competitive, thus increasing centralization; and a decline in user execution quality, with significant transaction price deviations and higher rollback probabilities. Jonathan noted that the timing design of decrypting after execution hinders the effective operation of auction mechanisms, which are optimal for handling MEV incentives. He suggested programmable privacy as an alternative, allowing a balance between full encryption and full transparency, currently achievable through TEE and potentially through more advanced solutions like FHE in the future. He concluded that privacy should not exist independently of economic incentives and should continue to be experimented with outside the protocol rather than being hastily integrated.#Ethereum #EncryptedMempools #MEV #BlockchainPrivacy #ThresholdEncryption #Flashbots #CryptoEconomics #Decentralization #ProgrammablePrivacy #FHE #TEE #Cryptography #TransactionOrdering #EthCC #ETH
