Introduzione

Tomorrow is a crucial day for Bitcoin, as significant changes to its Proof of Work (PoW) algorithm are on the horizon. Luke Dashjr, a Bitcoin developer and lead figure for the Bitcoin Knots project, has targeted Sunday, August 30th, for a major change that could shift the mining algorithm from SHA-256 to BLAKE2b. Dashjr advised miners using SHA-2 to halt operations on Saturday to prepare for a mainnet rehearsal using Bitcoin Knots version 29.4.1rc4. The plan is to finalize the last SHA-2 block and then, following a signal from a New York Post online publication, initiate a new chain using BLAKE2b. If successful, the final Bitcoin Knots 29.4.1 will launch on September 1st, preserving the blockchain history from August 30th. If issues arise, the system can be reverted to the last SHA-2 block for another attempt. Dashjr also recommended miners prepare on testnet4. This change, specific to Bitcoin Knots adopters and not a network-wide protocol update, could significantly impact current Bitcoin mining ASIC hardware, which is optimized for SHA-256 and cannot directly mine using BLAKE2b, potentially leading to a chain split if not widely adopted.

Luke Dashjr, a Bitcoin developer and leading figure in the Bitcoin Knots project, has named Sunday, August 30th, as the target date for a significant change to the Proof of Work (PoW) algorithm, which could affect Bitcoin's mining algorithm. Dashjr stated that miners using SHA-2 should halt mining on Saturday, as this will be used to prepare for a rehearsal launch of the Bitcoin Knots mainnet version 29.4.1rc4.

According to Dashjr's message, the Bitcoin Knots 29.4.1rc4 version will be configured to fix the final SHA-2 block before the transition. Then, after the online version of the Sunday morning edition of the New York Post is published, a 'canonical blake2b_headline' parameter will be provided, which will be used at the start of the new BLAKE2b-based chain.

Dashjr stated that if the process goes smoothly, the final version of Bitcoin Knots 29.4.1 will be released as planned on September 1st, and the blockchain history created on August 30th will be preserved.

However, the developer stated that if an unforeseen issue arises, the system can be rolled back to the last SHA-2 block and a new attempt made with the rc5 version.

Dashjr also recommended that those who want to start mining from the first day after the changes should prepare in advance on the testnet4 network using the Bitcoin Knots rc3 version.

What Technical Changes are Occurring?

The current Bitcoin Proof of Work system uses the SHA-256 hashing algorithm, which belongs to the SHA-2 family, during mining. Miners perform SHA-256 calculations to create new Bitcoin blocks.

The change mentioned by Dashjr involves using a different hashing algorithm called BLAKE2b in the PoW calculations.

BLAKE2b is a cryptographic function similar to SHA-256 that converts data into fixed-length hash values. However, because the computational structures of these two algorithms are different, most modern Bitcoin mining ASIC devices cannot directly mine using BLAKE2b.

Therefore, if such a change is implemented, it could mean not just a software update; it could also have significant implications for the hardware used by a substantial portion of Bitcoin's mining infrastructure.

The 'final SHA-2 block' Dashjr refers to is the last block generated according to the current SHA-256-based Proof of Work rules.

After this block, nodes using the new rules can begin to follow blocks created with BLAKE2b. However, if other nodes in the Bitcoin network do not adopt this change, the chain could split into two different rule sets.

Therefore, this initiative should not be considered as a final protocol change adopted by the entire Bitcoin network. Dashjr's statement specifically pertains to the planned process for the Bitcoin Knots software and the users who choose to adopt these rules.

How Can Bitcoin Resist Quantum Computers? A Comparative Analysis of Three Lattice-Based Signature Schemes

This report from Blockstream Research analyzes three lattice-based signature schemes as quantum-resistant candidates for Bitcoin, focusing on Dilithium, Falcon, and the now-withdrawn Hawk. Core evaluation criteria include on-chain costs (combined size of public key and signature), implementation complexity, deployment risks, and potential for integration with Bitcoin's existing infrastructure like BIP-32 hierarchical deterministic wallets. Key Findings: * **Dilithium** is praised for its design simplicity, using only integer operations, making secure implementation easier. However, it has the largest size (5,261 bytes for security level 3). * **Falcon** offers the most compact signatures and the fastest verification. Its main drawback—platform-dependent floating-point operations in signing—can be mitigated with a slower, deterministic integer-based implementation. The report recommends **Falcon-1024** (security level 5) for its safety margin. * **Hawk**, which aimed for a better balance, was withdrawn after a cryptographic attack revealed a structural flaw that halved its estimated security. The report concludes that Falcon-1024 is the most suitable lattice-based choice for Bitcoin, pending the finalization of its NIST FN-DSA standard. In the short term, it still recommends hash-based signatures (like SPHINCS+) as a lower-risk transitional solution, with future hybrid deployments as a possibility.

Bitcoin Outperforms Stocks and Correlates with Gold Precisely When It Matters Most

The price of Bitcoin surged 26% this month to around $79,200, outperforming gold (up 13.8%) and major stock indices. More importantly, its 30-day correlation with gold has risen to +0.81, indicating strong tandem movement, while its correlation with the US Dollar Index has deepened to -0.86, showing it moves opposite to the dollar. This highlights Bitcoin's appeal as a store of value and a hedge against fiscal and monetary concerns. Amid worries over the U.S. budget situation, which pushed long-term Treasury yields to multi-decade highs, traders anticipate the Federal Reserve may need to intervene by buying bonds. Bitcoin's price chart shows a bullish shift, with the 50-day moving average rising above the 100-day line and approaching a potential "golden cross" with the 200-day average. This suggests further price gains, though immediate resistance is seen around $82,814. The inability to sustainably hold above $80,000 this week indicates a possible deeper pullback before the next upward move.

Ripple (XRP) Company Announces Plans for Major Future Update

Ripple (XRP) has announced a four-phase plan to prepare the XRP Ledger (XRPL) for future security threats posed by quantum computers. The company's senior director of engineering stated the goal is to build necessary infrastructure before quantum computers become a direct threat, aiming to minimize impact on existing systems, user assets, and network operations. The plan begins with identifying potential quantum vulnerabilities within XRPL, followed by testing quantum-resistant cryptographic methods. The next phase involves parallel testing of existing security mechanisms and new quantum-resistant solutions to ensure reliability and prevent disruption for users and applications. The final phase would involve transitioning the XRPL to more comprehensive, quantum-resistant security standards if the technology matures. Ripple is also developing contingency plans for a faster-than-expected advancement of quantum computing, which could accelerate the transition timeline. A current XRPL feature allowing users to change the keys controlling their accounts without altering the accounts themselves is seen as a potential advantage in any future migration. However, Ripple cannot unilaterally change transaction validation rules or network-wide cryptographic standards; such updates require coordination and approval from independent validators via XRPL's governance process. While quantum computers are not yet capable of breaking the cryptography used by major blockchains like Bitcoin or XRPL, developers across the industry are already evaluating transition scenarios to quantum-resistant algorithms due to the long-term risks they pose to public-key cryptography.

Bitcoin ETFs Halt 9-Day Inflow Streak with $202 Million Outflow, While Ethereum Attracts $102 Million

Bitcoin ETFs experienced a net outflow of $202 million on August 28th, ending a nine-day streak of net inflows that had totaled approximately $3.04 billion and pushed the group's total net assets above $100 billion. This daily outflow marks a reversal from the recent trend, with notable outflows from Fidelity's FBTC and Grayscale's GBTC funds on the 27th, while iShares Bitcoin Trust (IBIT) saw significant inflows. Bitcoin ETFs had previously recorded a nine-day outflow streak in May, showing the market's volatility. In contrast, spot Ethereum ETFs extended their net inflow streak to ten consecutive days, attracting $102 million. This follows a period of strong support for Ether funds, which saw their highest weekly inflow since October earlier in August, largely driven by Blackrock's ETHA. The Bitcoin outflow coincided with a price drop from over $80,200 to around $77,500. Analysts suggest the single-day ETF sell-off may represent profit-taking rather than panic, especially given the expiration of approximately $6.4 billion in Bitcoin options. Market observers will monitor subsequent sessions to determine if this outflow is a temporary interruption or the start of a new trend, while Ether funds begin the new week continuing their positive run.
