The global cryptocurrency and blockchain landscape experienced a flurry of major developments on multiple fronts, highlighted by a definitive timeline from Beijing, a temporary technical roadblock for Ethereum, and an unexpected surge in Bitcoin network security despite a broader industry pivot toward artificial intelligence.
Government policy, software engineering, and hardware economics intersected to create a dynamic news cycle for digital assets, illustrating the diverse forces currently shaping the trajectory of decentralized technologies worldwide.
China targets 2030 for its national blockchain network buildout
China has set an explicit target year of 2030 for largely completing a national blockchain network, according to a comprehensive digital development plan published by the country’s central authorities.
The initiative forms a core component of the 15th Five-Year Plan for National Informatization. This strategic framework establishes national priorities for technological advancement, calling for the deeper implementation and integration of blockchain technology across various commercial and administrative sectors.
Specifically, the directive emphasizes the adoption of blockchain within trade and finance sectors across the economically vital Yangtze River Delta. Furthermore, the plan mandates deployment at scale within manufacturing and agriculture industries throughout the Chengdu-Chongqing region located in southwestern China.
The overarching blueprint was officially issued by the Central Cyberspace Affairs Commission, a senior coordinating body operating within the ruling Communist Party that governs national digital development policies and cybersecurity strategies.
By formally establishing a 2030 completion target, the newly released document provides a firm deadline for a project that has steadily progressed through official channels. The national blockchain network was previously included in broader national development guidelines released in March, and a joint policy published on October 9 by the Communist Party’s central leadership and the State Council had similarly called for its systematic construction.
This sustained policy focus underscores Beijing’s ongoing commitment to integrating enterprise-grade blockchain infrastructure into its domestic economic framework, distinct from its stringent prohibitions on public cryptocurrency trading and speculative token issuance.
Ethereum delays Glamsterdam Hoodi testnet launch over security risks
In the decentralized application sphere, Ethereum developers have chosen to postpone the implementation of the anticipated Glamsterdam hard fork on the Hoodi testnet. The decision came after security researchers identified critical gas-related vulnerabilities that could negatively affect how existing smart contracts handle failed transactions.
The Ethereum Foundation announced that the upgrade, which was originally scheduled to go live on October 26, would be delayed indefinitely to allow core developers and researchers ample time to investigate how specific protocol proposals interact with smart contracts already deployed on the Ethereum mainnet.
The technical concerns initially came to light on October 13, when blockchain security firm ChainSecurity published an advisory warning that two specific proposals included in the Glamsterdam upgrade—designated as EIP-8037 and EIP-8038—could inadvertently weaken established safeguards against a specific class of exploit known as insufficient gas griefing.
This unexpected postponement introduces a notable degree of uncertainty regarding the ultimate timeline for the Glamsterdam mainnet rollout. Prior to the security advisory, Ethereum developers had been eyeing an early December target for mainnet deployment, with formal schedules intended to be locked in only after a successful testing phase on the Hoodi testnet.
The delay highlights the ongoing cautious approach that core developers maintain toward major protocol upgrades, prioritizing network security and contract integrity over speed.
Bitcoin mining competition heats up despite AI exodus
Meanwhile, the Bitcoin network is experiencing a powerful resurgence in computational security. Network hashrate has climbed to a seven-month high, driven by intensifying competition among miners even as major institutional mining companies aggressively shift their operational capacity toward artificial intelligence infrastructure, according to data from BlocksBridge Consulting.
Bitcoin’s seven-day moving average hashrate has pushed back above 1 zettahash per second for the first time since March 3. This milestone suggests that the substantial amounts of computing power previously leaving the network as firms pivot to high-performance computing are being rapidly replaced by incoming hardware and rival operations.
Hashrate serves as the primary metric measuring the total computational power securing the Bitcoin network against attacks, while mining difficulty dictates the mathematical complexity required to discover new blocks and earn block rewards.
Reflecting this surging competition, Bitcoin’s mining difficulty experienced a 5.92% upward adjustment on October 16. BlocksBridge has projected a further 5.16% difficulty increase for the subsequent adjustment window. Combined, these successive adjustments represent an estimated 11.4% increase in mining difficulty across a short span, compounding the operational challenge for participants seeking to earn network rewards.
This expansion in network security and difficulty arrives against the backdrop of a significant corporate migration. Publicly traded Bitcoin mining enterprises have recently reported a collective 23% decline in realized hashrate as they intentionally redirect valuable electrical and spatial resources toward artificial intelligence data centers.
Data shows that these firms have seen their AI-related revenue surge by 52% quarter over quarter, making high-performance computing a lucrative alternative to traditional block rewards. Industry analysts at BlocksBridge estimate that approximately $1.5 billion worth of traditional mining hardware has been actively displaced by this structural corporate transition.
Rather than slowing the network down, however, much of this displaced hardware is finding a second life. Smaller, independent mining operations—particularly those with access to localized, low-cost electricity sources—have stepped in to acquire the discarded equipment, allowing them to expand their footprint while their larger, publicly traded competitors focus heavily on artificial intelligence ventures.
