Bitcoin: hashrate at seven months of peak despite exodus to AI

The Bitcoin network has reached an average hashrate of 1 zettahash per second, the highest level since March 3, 2024, despite the migration of part of the computing capacity to high-intensity AI data centers. This phenomenon, reported by BlocksBridge Consulting, highlights growing competition in the mining sector.

The increase in hashrate indicates that the computing power leaving the network is quickly replaced by new miners, compensating for the 23% reduction in realized hashrate reported by major public mining companies. These companies have redirected their resources to AI, recording a 52% increase in revenue related to this technology in the quarter.

Quick Answer

  • Bitcoin's average hashrate has exceeded 1 zettahash per second, the highest level since March 2024
  • Mining difficulty increased by 5.92% on October 16, with a further forecast of 5.16% for the next adjustment
  • About $1.5 billion worth of mining equipment has been moved to AI, potentially finding new buyers among smaller miners

The impact of mining difficulty

Mining difficulty increased by 5.92% on October 16, with a forecast of a further increase of 5.16% at the next adjustment. This represents an overall increase of 11.4% in two adjustments, making it more difficult for miners to obtain rewards. The increase in difficulty is a clear signal of growing competition in the sector, despite the 23% reduction in realized hashrate reported by major public mining companies.

The transition to AI and opportunities for smaller miners

BlocksBridge estimates that about $1.5 billion worth of mining equipment has been moved to AI. This hardware could find new buyers among smaller miners with access to cheaper electricity, allowing them to expand operations while larger competitors pursue opportunities in AI. The transition to AI is creating new dynamics in the mining sector, with potential benefits for smaller and more flexible miners.

Starknet: the community votes for research on an independent layer-1

The Starknet community has approved with 93.52% of the votes a proposal to start research on the possibility of becoming an independent, post-quantum layer-1. The vote, which recorded the highest participation in the history of Starknet governance, was conducted for seven days and ended on Thursday. The proposal is not binding but allows StarkWare and the Starknet Foundation to proceed with the research.

Implications for the Ethereum ecosystem

Starknet, currently a layer-2 of Ethereum, could become an independent layer-1 if the community approves a subsequent binding vote. This development could have significant implications for the Ethereum ecosystem, potentially reducing Starknet's dependence on the underlying blockchain. The decision to proceed with the research is an important step towards greater autonomy for Starknet.

The PHP Foundation admits a delay in fixing a critical vulnerability

The PHP Foundation has acknowledged that indecision and lack of resources have delayed the fixing of a critical vulnerability first identified in 2024. The foundation described the delay as a "structural failure" caused by a complex decision-making process and lack of resources. The vulnerability could allow unauthenticated attackers to execute code on affected servers without access.

The challenges in fixing the vulnerability

The foundation explained that developers first noticed signs of the vulnerability in 2024 but had difficulty finding a solution that would not disrupt the vast ecosystem of software built with PHP. The lack of a known path for remote code execution and the small team of developers with in-depth knowledge of the engine contributed to the delay. The foundation was reported again on the vulnerability on August 11, after security firm Calif and OpenAI independently reported the same underlying issue.

The implications for web security

The future of Bitcoin mining between AI and sustainability

The current dynamism in the Bitcoin mining sector raises questions about the future of mining technology. The adoption of more energy-efficient hardware could accelerate, driven by the need to compete with AI data centers. This scenario opens new opportunities for miners operating in regions with renewable energy sources, such as Iceland or Canada, where hydroelectric and geothermal energy offers significant competitive advantages.

The evolution of regulation and challenges for miners

Growing regulatory attention to carbon emissions in the mining sector could lead to new regulations. Countries like the United States and the European Union are considering measures to reduce the ecological footprint of cryptocurrency mining. Miners will need to adapt to these changes, investing in cleaner technologies or participating in carbon emission offset programs.

The impact on the decentralization of the Bitcoin network

The concentration of computing power among a few large players is a recurring theme in the debate on the decentralization of Bitcoin. The current migration to AI could further reduce the geographic diversification of miners, concentrating computing power in regions with advanced technological infrastructure. This phenomenon requires continuous monitoring by the community to ensure that the network maintains its decentralized character.

Starknet: the technical challenges of a transition to layer-1

The transition of Starknet to an independent layer-1 presents significant technical challenges. The network will have to address issues related to scalability, security, and compatibility with existing smart contracts. The ongoing research will need to carefully evaluate the impact of such changes on the ecosystem of current developers and users, ensuring a smooth and uninterrupted migration.

Implications for dApp developers

Developers of decentralized applications (dApps) on Starknet will need to adapt their technological solutions to a potential new execution environment. The developer community will need to work closely with the Starknet Foundation to ensure that transitions are smooth and that new features are introduced without disrupting existing operations.

PHP security: lessons learned and future improvements

The security incident in PHP highlights the need for more robust vulnerability management in open-source programming languages. The developer community could benefit from a more structured approach to vulnerability management, with faster decision-making processes and adequate resources to address emerging threats. Collaboration with external security experts could accelerate the identification and fixing of critical vulnerabilities.

The importance of cybersecurity training

The lack of human resources with specific skills in the PHP engine contributed to the delay in fixing the vulnerability. Investing in training and skill development programs could help bridge this gap, ensuring that development teams are able to address security challenges more effectively. Collaboration between universities and technology companies could accelerate the training of new cybersecurity experts.

The role of cyber insurance in risk mitigation

The adoption of cyber risk policies could offer additional protection for organizations using PHP. Cyber insurance can cover the costs associated with security incidents, including damage caused by vulnerabilities not corrected in time. Companies should carefully evaluate the options for cyber insurance premiums to ensure adequate coverage.

The adoption of zero trust architectures for web security

The implementation of zero trust architectures could improve the security of PHP-based websites. This security approach is based on the principle of "never trust, always verify," limiting access to resources only to authorized users. Organizations should consider adopting identity access management systems to more effectively manage user authorizations.

The need for a proactive approach to security

Proactive vulnerability management requires the adoption of MDR services and SIEM systems to continuously monitor IT infrastructures. Organizations should invest in advanced Data Loss Prevention tools to prevent the loss of sensitive data and ensure compliance with current regulations.
