The cryptocurrency landscape experienced a wave of significant developments as core infrastructure projects adjusted their timelines and strategic visions. Ethereum developers opted to postpone an upcoming testnet fork to thoroughly evaluate critical security concerns, while the Bitcoin network demonstrated remarkable resilience and rising competition even as major institutional miners pivot toward the booming artificial intelligence sector. Meanwhile, the Starknet community delivered a resounding governance verdict, overwhelmingly backing exploratory research into transforming the popular scaling network into an independent, post-quantum layer-1 blockchain.
Ethereum delays Glamsterdam Hoodi testnet launch over security risks
Ethereum developers have officially postponed the scheduled Glamsterdam hard fork on the Hoodi testnet following cautionary findings from blockchain researchers regarding gas-related vulnerabilities. The proposed network upgrades could potentially alter how existing smart contracts handle failed transactions, introducing unintended risks to decentralized applications operating across the ecosystem.
The Ethereum Foundation announced that the upgrade, which was originally slated for deployment on October 26, would be delayed indefinitely to afford core developers adequate time to investigate how specific improvement proposals interact with smart contracts already active on the network. The decision underscores the meticulous caution that core development teams exercise when implementing protocol-level changes that could impact the broader economic and operational security of the blockchain.
The root of the delay traces back to an October 13 security advisory published by blockchain security firm ChainSecurity. The audit firm warned that two specific proposals integrated into the broader Glamsterdam upgrade package—identified as EIP-8037 and EIP-8038—could inadvertently weaken crucial defensive safeguards designed to protect users and protocols against a specific class of attack known as insufficient gas griefing. This attack vector can manipulate transaction execution flows and disrupt the reliable functioning of complex decentralized finance protocols.
This unexpected postponement introduces a notable layer of uncertainty regarding the overarching timeline for the Glamsterdam mainnet rollout. Prior to the security advisory, Ethereum developers had been actively contemplating a mainnet deployment window in early December, with the explicit understanding that a finalized schedule would only be locked in after observing successful, unhindered testing phases on the Hoodi testnet. With the initial testnet deployment now pushed back, developers and ecosystem participants must wait for further evaluations to determine a realistic path forward.
Bitcoin mining competition heats up despite AI exodus
In the realm of proof-of-work consensus, Bitcoin’s network hashrate has surged to a striking seven-month high. This robust growth persists despite a widespread, well-documented industry trend wherein major enterprise mining corporations are aggressively redirecting their massive computing infrastructure toward artificial intelligence and high-performance computing data centers, according to data from BlocksBridge Consulting.
The seven-day moving average of Bitcoin’s network hashrate has climbed decisively above the milestone of 1 zettahash per second for the first time since March 3. This high-water mark strongly implies that the vast quantities of computing power leaving the network as corporate players pivot toward AI are being swiftly replaced and surpassed by incoming hardware and alternative mining operations.
Hashrate fundamentally serves as a direct measurement of the total computational power actively securing the Bitcoin network against malicious actors, whereas mining difficulty dictates the mathematical complexity required to successfully discover a new block and earn block rewards. Reflecting this escalating computational arms race, network mining difficulty underwent a substantial 5.92% upward adjustment on October 16. Furthermore, analytical projections from BlocksBridge indicated that another difficulty adjustment of approximately 5.16% loomed on the horizon. Combined, these consecutive adjustments translate to a formidable 11.4% cumulative increase in difficulty, compounding the operational hurdles miners face in securing consistent rewards.
This intense tightening of mining economics occurs against a backdrop where publicly traded mining enterprises have reported a 23% aggregate decline in their realized hashrate capacity. These large-scale operators continue to reallocate resources toward lucrative AI infrastructure, reporting a notable 52% quarter-over-quarter increase in AI-related revenue streams.
Industry estimates compiled by BlocksBridge suggest that approximately $1.5 billion worth of specialized mining hardware has been actively displaced by this structural corporate transition. However, a significant portion of this high-performance equipment is finding a second life. Smaller, independent miners equipped with access to competitively priced electricity are absorbing the displaced hardware, expanding their localized operations even as their massive publicly traded counterparts chase the financial allure of artificial intelligence.
Starknet voters back research into life beyond Ethereum
Shifting to the layer-2 scaling ecosystem, the Starknet community has delivered a decisive mandate supporting formal research into transitioning the network into an independent, post-quantum layer-1 blockchain. The ambitious proposition to potentially sever ties with Ethereum as the primary settlement layer captured overwhelming support from tokenholders during a governance process that concluded following a seven-day voting window.
The non-binding community poll, which officially closed on Thursday, recorded what StarkWare confirmed as the highest level of voter participation in Starknet’s governance history. The proposal drew approximately 3,200 individual votes, with an emphatic 93.52% of the participating voting power casting ballots in favor of authorizing the exploratory research. To maintain neutrality and allow the decentralized community to steer its own destiny, StarkWare leadership officially abstained from participating in the vote.
While the community outcome clears the path for StarkWare and the Starknet Foundation to dedicate resources and engineering talent toward investigating the feasibility of an independent layer-1 architecture, any actual structural migration remains a distant prospect. An eventual operational shift would necessitate a completely separate, legally and technically binding governance vote in the future. For the foreseeable future, Starknet will continue to function precisely as designed—operating as a prominent Ethereum layer-2 scaling network anchored to the mainnet.
Reflecting on the historic community decision, StarkWare CEO Eli Ben-Sasson shared insight into the immediate next steps with industry reporters, noting that development teams were already initiating work on a foundational whitepaper ahead of the weekend. The leadership team expressed an ambitious goal to finalize and release an initial draft for rigorous public scrutiny and community debate as early as November.
