#QuantumComputing #Bitcoin #Blockstream #Cryptography #PostQuantum #PQsignatures
According to Odaily, Adam Back, co-founder and CEO of Blockstream and inventor of Hashcash, has suggested that quantum computing could potentially strengthen the Bitcoin network. Despite concerns within the industry about the advancements in quantum physics, which allow quantum computing to perform calculations at unprecedented speeds and potentially compromise cryptographic algorithms, Back remains optimistic. He stated on X that post-quantum (PQ) developments are still decades away. He emphasized that hash-based PQ solutions are not feasible, but ongoing research into PQ signatures will eventually yield conservative, well-reviewed, and more compact signatures. Bitcoin could adopt these as an alternative option.#QuantumComputing #Bitcoin #Blockstream #Cryptography #PostQuantum #PQsignatures

According to PANews, Coin Metrics co-founder Nic Carter has identified quantum computing as the most significant long-term threat to Bitcoin's core cryptography. Carter explained the one-way nature of deriving public keys from private keys using the secp256k1 elliptic curve and highlighted that public keys become exposed on the blockchain when transactions are spent, increasing the potential attack surface.
Carter advised against address reuse in the near term to minimize public key exposure. He also emphasized the importance of developing quantum-resistant signature schemes and feasible migration paths in the long term. Carter's series of articles will continue to explore scenarios in a 'post-quantum break' world.#QuantumComputing #Bitcoin #Cryptography #secp256k1 #EllipticCurve #PublicKeyExposure #QuantumResistance #SignatureSchemes #PostQuantum #NicCarter #BTC
🚀 Quantum Computing's Threat to Cryptography Overstated, Report Finds
#QuantumComputing #Cryptography #Blockchain #QuantumThreat #PostQuantum #Encryption #PrivacyChains #Bitcoin #HybridEncryption #HNDL #DigitalSignatures #QuantumSecurity
According to ChainCatcher, while quantum computers pose a long-term threat to cryptography, the actual risk is often exaggerated. A report indicates that the likelihood of 'cryptography-relevant quantum computers' capable of breaking modern encryption systems emerging before 2030 is very low.
Venture capital firm a16z recommends the immediate deployment of hybrid encryption schemes to counter 'harvest now, decrypt later' (HNDL) attacks. However, it suggests that blockchain technology does not need to rush into adopting post-quantum signature technology, as digital signatures are not affected by HNDL attacks.
Bitcoin faces unique challenges due to its slow governance mechanisms and the potential abandonment of quantum-vulnerable coins, necessitating early planning for migration paths. Privacy chains, which encrypt transaction data, have a more urgent need for post-quantum protection.
The report emphasizes that current security implementations and vulnerabilities are more pressing threats than the distant risks posed by quantum computing. It outlines seven specific recommendations to help the industry address quantum challenges.#QuantumComputing #Cryptography #Blockchain #QuantumThreat #PostQuantum #Encryption #PrivacyChains #Bitcoin #HybridEncryption #HNDL #DigitalSignatures #QuantumSecurity
🚀 Exploring Quantum-Resistant Solutions for Bitcoin Blockchain
#QuantumResistance #BitcoinBlockchain #PostQuantum #HashBasedSignatures #QuantumSecurity #Cryptanalysis #NIST #DigitalSignatures #QuantumComputing #BlockchainUpgrade #Cryptography #BitcoinDeveloper #BTC
According to PANews, Blockstream researchers Mikhail Kudinov and Jonas Nick have examined various methods to upgrade the Bitcoin blockchain for quantum resistance in a revised paper published on December 5. They propose hash-based signatures as an attractive post-quantum solution due to their security relying solely on hash function assumptions, similar to Bitcoin's foundational design. Kudinov shared his findings with the Bitcoin developer mailing list, noting that these schemes have undergone extensive cryptanalysis during the National Institute of Standards and Technology's (NIST) post-quantum standardization process, boosting confidence in their robustness.
Hash-based signatures depend on hash functions, which are considered quantum-resistant mathematical algorithms. Unlike Bitcoin's public key encryption, quantum algorithms struggle to break hash functions. By simply increasing the output size, hash functions can counteract brute-force searches by quantum computers, ensuring the security of applications like digital signatures. However, the implementation of hash-based signatures remains under discussion. Decisions are needed on issues such as maintaining low verification costs, standardizing various hash-based signature implementations, and whether the entire network's historical record is necessary for transaction verification.#QuantumResistance #BitcoinBlockchain #PostQuantum #HashBasedSignatures #QuantumSecurity #Cryptanalysis #NIST #DigitalSignatures #QuantumComputing #BlockchainUpgrade #Cryptography #BitcoinDeveloper #BTC

Optimism has announced a post-quantum roadmap for its Superchain. According to Foresight News, the plan includes phasing out ECDSA-based external accounts (EOA) on the OP mainnet and Superchain within ten years, contingent upon governance approval. All ECDSA EOAs will need to delegate private key management to post-quantum smart contract accounts. Once the transition period ends, OP Stack chains will gradually eliminate transactions using original ECDSA signatures for EOAs. The OP Stack chains will follow a unified roadmap to ensure upgrades are synchronized across the entire Superchain network.#Optimism #PostQuantum #Superchain #ECDSA #OPMainnet #SmartContracts #Governance #Blockchain #QuantumSecurity #OPStack

Bitcoin developers have introduced BIP 360, which proposes the Pay-to-Merkle-Root (P2MR) method to tackle potential vulnerabilities posed by quantum computing. According to NS3.AI, this proposal aims to enhance Bitcoin's security without immediate activation. Experts are divided on the timeline for quantum computers to pose a real threat to Bitcoin's cryptography, with estimates ranging from five years to several decades. The implementation of post-quantum security measures in Bitcoin is complicated by the network's decentralized consensus mechanism and community resistance to change.#Bitcoin #BIP360 #PayToMerkleRoot #QuantumComputing #BitcoinSecurity #PostQuantum #Cryptography #Decentralization #BTC

IBM is working with messaging platforms Signal and Threema to develop quantum-resistant messaging protocols aimed at protecting against future encryption attacks. According to NS3.AI, the initiative addresses concerns over 'harvest now, decrypt later' strategies, where adversaries could potentially record encrypted communications today and decrypt them once quantum computing becomes more advanced. Signal has already implemented PQXDH and SPQR post-quantum upgrades, while Threema is considering the integration of the National Institute of Standards and Technology-standardized ML-KEM algorithm with IBM's assistance.#IBM #Signal #Threema #QuantumComputing #QuantumResistant #PostQuantum #Encryption #Cybersecurity #PQXDH #SPQR #MLKEM #NIST
🚀 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
