Investors scanning October crypto stocks have a fresh list to work from. MarketBeat's stock screener on Thursday identified seven cryptocurrency-related stocks to watch based on recent dollar trading volume: Galaxy Digital, Bitfarms, HIVE Digital Technologies, Ionic Digital, Soluna, ZenaTech and Digi Power X.
The screen arrives as regulators cleared crypto platforms to continue paying interest-style rewards on certain digital assets, a decision Yahoo Finance reported keeps fresh capital flowing into this corner of the market. That backdrop keeps attention on businesses building the underlying infrastructure of digital finance, from blockchains to payment rails.
Why October crypto stocks are drawing volume
According to MarketBeat, the term covers shares of listed companies whose operations are significantly tied to cryptocurrencies or blockchain technology. They can include exchanges, miners, payment providers and firms that hold digital assets, letting stock market investors gain indirect exposure to the sector without buying tokens directly.
The seven names on the list posted the highest dollar trading volume of any cryptocurrency stocks over the last several days, MarketBeat reported. The group offers varied exposure to the sector, spanning digital-asset financial services, cryptocurrency mining, blockchain infrastructure, data-center hosting and digital-asset management.
Most of the featured firms are miners or infrastructure providers. Galaxy Digital stands apart with broader trading, investment banking, asset management and investment services, while ZenaTech pairs enterprise software and drone technology with cryptocurrency wallets, according to MarketBeat.
Galaxy Digital and the miners on the list
Galaxy Digital Holdings Ltd. is a financial services and investment management company operating in the digital asset, cryptocurrency and blockchain technology sectors. Its segments include Trading, Principal Investment, Asset Management, Investment Banking, Mining, and Corporate and Other, according to MarketBeat.
Bitfarms Ltd. mines cryptocurrency coins and tokens in Canada, the United States, Paraguay and Argentina. It owns and operates server farms that primarily validate transactions on the Bitcoin blockchain, earning cryptocurrency from block rewards and transaction fees, and it also provides electrician services to commercial and residential customers in Quebec, Canada.
HIVE Digital Technologies Ltd. operates as a cryptocurrency mining company in Canada, Sweden and Iceland, mining and selling digital currencies including Ethereum Classic and Bitcoin. The company also runs data centers and offers infrastructure solutions, and it was formerly known as HIVE Blockchain Technologies Ltd.
Infrastructure and hosting names round out the screen
Ionic Digital is a digital infrastructure solutions and cryptocurrency mining company, according to MarketBeat. Soluna Holdings, together with its subsidiaries, mines cryptocurrency through data centers and operates through two segments, Cryptocurrency Mining and Data Center Hosting.
Soluna also operates in the blockchain business and develops and builds modular data centers used for cryptocurrency mining. Digi Power X, listed as Digihost Technology Inc., operates as a blockchain technology company focused on digital currency mining in the United States; it was incorporated in 2017 and is headquartered in Toronto, Canada.
ZenaTech, Inc. is an enterprise software technology company developing cloud-based software applications in Canada. Its products include cryptocurrency wallets, enterprise software for the agriculture and medical records industries, safety and compliance management tools, field management software, drone technology solutions and browser-based applications for public safety, according to MarketBeat.
Beyond the screen: other October crypto stocks in focus
The seven names are only a starting point. Yahoo Finance reported that a broader screen surfaced 17 more crypto and blockchain companies with comparable narratives, among them Cipher Digital and Cellebrite DI.
Cipher Digital develops industrial-scale U.S. data centers focused on bitcoin mining, an activity that generated US$191 million, while building high-performance compute hosting for hyperscalers, according to Yahoo Finance. The firm carries a market value of about US$3.7 billion, tying its fortunes closely to crypto-linked infrastructure and making it one of the more pure-play infrastructure picks in that screener.
Yahoo Finance described the company's shift in strategy, writing: The rapid expansion and optimization of production capacity has shifted from adding Bitcoin hash rate to delivering hyperscale AI and high performance computing campuses such as Barber Lake, Black Pearl and Stingray. The report added that Signed leases and active construction are expected to convert gigawatt scale power into contracted rent streams that drive future revenue and net operating income.
Cipher Digital's appeal hinges on how one large, long-dated financial commitment flows through to cash generation and margins, and whether those rent streams outrun power and build costs over time, Yahoo Finance reported.
Forensics and compliance exposure
Cellebrite DI builds digital investigation software that helps agencies interpret complex data trails, with a specific role in untangling cryptocurrency-related financial crime through its forensics and analytics platforms, according to Yahoo Finance. The company generates about US$514 million from internet software and services and has a market value of roughly US$2.9 billion.
For crypto-focused investors, the business matters because its tools sit where digital evidence, blockchain activity and law enforcement needs converge, giving it a direct role in addressing the more complex side of digital assets, Yahoo Finance reported.
MarketBeat noted that Galaxy Digital currently holds a Moderate Buy rating among analysts, though the outlet said top-rated analysts believe five other stocks it tracks are better buys. The outlet did not name those stocks in the alert.
Conclusion
MarketBeat's screener has put seven cryptocurrency-linked names, led by Galaxy Digital and a group of miners and data-center operators, on the watch list for October crypto stocks based on recent dollar trading volume. The regulatory decision allowing platforms to continue paying interest-style rewards on certain digital assets keeps money moving into the sector, according to Yahoo Finance. The next concrete marker for investors is whether Cipher Digital's signed leases and active construction convert gigawatt-scale power into contracted rent streams, and whether those streams outrun power and build costs.

Ethereum Blob Fees are the fees paid for including temporary data blobs in Ethereum transactions. They were introduced through EIP-4844, also known as Proto-Danksharding, as part of the Dencun upgrade in March 2024.
Blobs provide Layer 2 rollups with a dedicated way to publish transaction data to Ethereum without using the traditional calldata pricing model. Ethereum’sofficial EIP-4844 specification describes blob gas as a separate fee market with its own base fee.
This distinction matters because Ethereum has two different resource markets involved in these transactions:
Regular execution gas
Blob gas
The price of one does not directly determine the price of the other.
For Layer 2 users, this creates a potentially important cost-saving mechanism because rollups can batch transactions and publish compressed data through blobs.
What Is Proto-Danksharding?
Proto-Danksharding is the first major stage of Ethereum’s longer-term danksharding roadmap.
Ethereum’sDanksharding roadmap explains that Proto-Danksharding adds data blobs to Ethereum blocks, giving rollups a cheaper way to publish data.
The term can sound complicated, but the basic idea is relatively straightforward.
A Layer 2 processes many transactions away from Ethereum Mainnet. It then needs to publish sufficient information back to Ethereum so that the rollup’s state can be independently verified.
Before blobs, rollups relied heavily on calldata for this data publication.
With EIP-4844, rollups can use dedicated blob space instead.
This does not mean blobs are permanent storage. Ethereum documentation states that blobs are intended to remain available for roughly 18 days, after which they can be pruned from ordinary clients. Long-term archival availability is a separate concern.
How Ethereum Blob Fees Work
The blob fee market is similar in concept to Ethereum’s EIP-1559 execution-fee market, but it operates separately.
EIP-4844 introduced:
Blob gas
A blob base fee
A target amount of blob space
A maximum amount of blob space
An excess blob gas value used to adjust pricing
The protocol calculates the blob base fee according to blob-space demand.
When blob usage exceeds the target, excess blob gas accumulates and the blob base fee can rise.
This means Ethereum Blob Fees are driven primarily by demand for blob space rather than by the computational complexity of ordinary smart-contract execution.
Ethereum Blob Fees vs Normal Gas Fees
One of the easiest mistakes is treating blob fees and normal Ethereum gas fees as the same thing.
They are not.
A normal Ethereum execution fee is associated with computation and other execution-layer resources.
A blob fee is associated with data availability space.
A rollup transaction can therefore be affected by both.
This separation allows the blob market to respond specifically to demand for Layer 2 data availability.
How Ethereum Blob Fees Affect L2 Costs
Layer 2 users typically do not pay the raw Ethereum blob fee as a separate line item.
Instead, rollup operators incur costs for publishing data to Ethereum and generally incorporate those costs into the L2 fee structure.
For optimistic rollups, Ethereum identifies several components of user fees, including L1 data publication, blob gas, and L2 operator costs.Ethereum’s optimistic-rollup documentation explains how these components work together.
For ZK-rollups, fees can also include data publication, L2 operator costs, and proof-related expenses.Ethereum’s ZK-rollup documentation describes these components.
This means lower Ethereum Blob Fees can reduce one important cost faced by rollups, but they do not automatically make every L2 transaction free or equally cheap.
Why Blobs Are Cheaper Than Calldata
Calldata and blobs both allow rollups to publish information to Ethereum, but they have different pricing and storage characteristics.
Calldata remains part of Ethereum’s permanent historical data and is priced through regular execution gas.
Blobs are temporary data objects with a dedicated fee market.
Ethereum’s documentation explains that blobs were designed specifically for rollup data and are generally cheaper than calldata for this use case. The data remains available during the protocol’s required serving window, while longer-term access can be handled by archival systems.
The difference is therefore not simply that blobs are “cheap storage.”
They are better understood as temporary data availability infrastructure designed for rollups.
Ethereum Blob Fees and Data Availability
Data availability is essential to rollup security.
A rollup publishes data to Ethereum so independent participants can reconstruct and verify the rollup’s state.
This is one reason blob fees matter beyond simple transaction pricing.
The goal is not merely to reduce costs. Ethereum needs a scalable way for rollups to make relevant data available without overwhelming node operators.
Proto-Danksharding therefore attempts to balance:
Rollup data availability
Network capacity
Node-resource requirements
L2 affordability
Ethereum security
Ethereum Blob Fees and Blob Capacity in 2026
The blob system has expanded significantly since EIP-4844 first launched.
The original Dencun configuration targeted 3 blobs per block and allowed a maximum of 6 blobs.
Ethereum later increased these limits through subsequent upgrades.
Following Fusaka and its Blob Parameter Only upgrades, Ethereum reached a target of 14 blobs per block and a maximum of 21 blobs per block in January 2026.
Ethereum’s January 2026 protocol checkpoint described this as a 2.3× increase in L2 data space compared with the pre-Fusaka configuration. The canonicalBPO2 specification records the 14-target and 21-maximum configuration.
This is important for L2 economics because more available blob space can reduce the likelihood that rollups compete for a severely constrained data-availability resource.
However, greater capacity does not guarantee permanently low blob fees.
If demand increases faster than capacity, blob prices can rise again.
Current 2026 Ethereum Blob Fee Conditions
A recentBlobscan Ethereum Mainnet snapshot shows blob gas pricing at only a few million wei per blob gas unit, equivalent to roughly 0.005 Gwei per blob gas in the snapshot reviewed for this article.
The same snapshot showed approximately 22 million blobs, around 4.5 million blocks, and about 2.67 TiB of total blob data size recorded on Ethereum Mainnet.
These figures change continuously, so they should be treated as a point-in-time snapshot rather than a permanent average.
They also illustrate an important feature of the blob market: prices can remain low when available blob capacity comfortably exceeds current demand.
A June 2026 Blobscan block example showed a blob gas price of approximately 0.011 Gwei, again indicating how low blob pricing can become during periods of relatively modest demand.
For live conditions, readers should use a current blob explorer rather than relying on a historical article snapshot.
Why Low Ethereum Blob Fees Do Not Guarantee Cheap L2 Transactions
It is tempting to conclude that low blob fees automatically mean extremely cheap L2 transactions.
The relationship is more complicated.
An L2 transaction can include several cost components:
L1 data publication
L2 execution
L2 operator fees
Proof generation
Proof verification
Sequencer-related costs
Network-specific overhead
For example, ZK-rollups may have additional proof-generation and verification costs that do not appear in the blob market itself.
Transaction complexity also differs between applications.
A simple token transfer may require less data than a more complex DeFi interaction.
Therefore, Ethereum Blob Fees are an important variable, but they are only one component of the final amount a user pays.
Ethereum Blob Fees and Rollup Compression
Compression is another major part of L2 fee economics.
Rollups do not necessarily publish every transaction in the same raw format used by users.
Instead, transaction data can be compressed and batched so that one Ethereum publication covers many L2 transactions.
This spreads the cost of posting data across a larger number of users.
Ethereum’sLayer 2 scaling documentation explains how rollups batch transactions and publish data to Ethereum to reduce per-transaction costs.
This is why changes in blob pricing can have different effects across rollups.
An L2 with efficient compression and large batches may respond differently from an L2 with higher data requirements.
Ethereum Blob Fees and Rollup Competition
A larger blob market can influence competition between Layer 2 networks.
When data availability is scarce and expensive, rollups face greater costs for posting batches.
As blob capacity increases, that constraint can become less severe.
This can give rollups more room to scale transaction throughput without paying the same data-publication cost.
Ethereum’s 2026 protocol roadmap continues to prioritize additional blob scaling. TheEthereum Foundation’s 2026 protocol priorities update states that further blob-parameter increases remain part of the broader scaling work.
This suggests the blob market is still an evolving component of Ethereum’s scaling architecture rather than a finished design.
Ethereum Blob Fees and Full Danksharding
Proto-Danksharding is not the final destination.
Ethereum’s longer-term danksharding roadmap aims to expand data availability substantially while using data-availability sampling.
TheEthereum Danksharding roadmap explains that later stages are designed to allow validators to verify blob availability through sampling rather than requiring every node to process the entire data set in the same way.
The objective is greater data capacity while preserving Ethereum’s security and decentralization properties.
Proto-Danksharding therefore provides the current infrastructure and fee market from which future scaling improvements can evolve.
How Traders and Developers Should Think About Ethereum Blob Fees
For developers building on L2s, blob economics can influence transaction costs, batching strategies, and application design.
For users, the main point is simpler:
L2 fees are not determined by Ethereum Mainnet gas alone.
Blob demand is another important variable.
When blob fees are low, rollups may face lower L1 data-publication costs. When demand rises and blob space becomes more competitive, those costs can increase.
A useful way to understand the market is to track:
Blob base fee
Blob utilization
Target vs maximum blob count
L2 transaction fees
Data-compression efficiency
Rollup activity
Ethereum execution fees

Common Misunderstandings About Ethereum Blob Fees
Blob Fees Are the Same as ETH Gas Fees
They are separate pricing mechanisms, even though both are measured through gas-like units.
Blobs Are Permanent Ethereum Storage
They are temporary data-availability objects rather than permanent archival storage.
Low Blob Fees Mean Every L2 Transaction Is Cheap
L2 fees include other components beyond blob publication.
More Blobs Always Mean Lower Fees
More capacity can reduce scarcity, but demand can increase at the same time.
Proto-Danksharding Is Full Danksharding-
Proto-Danksharding is an intermediate stage of Ethereum’s broader data-availability scaling roadmap.
Ethereum Blob Fees: Practical Checklist
When evaluating L2 cost trends, check:
Blob base fee: What is the current blob price?
Utilization: Is blob capacity heavily used?
Target: How many blobs does Ethereum currently target?
Maximum: What is the per-block maximum?
L2 data usage: How much data does the rollup publish?
Compression: How efficiently does the L2 batch transactions?
Execution fees: What does the L2 charge for computation?
Proof costs: Are proof-generation or verification expenses significant?
Network activity: Is L2 demand rising?
Capacity roadmap: Are additional blob increases planned?
Ethereum Blob Fees are a separate pricing mechanism for the temporary data space introduced by Proto-Danksharding.
EIP-4844 gave Layer 2 rollups a dedicated way to publish data to Ethereum, reducing reliance on more expensive calldata for rollup data.
Since its introduction, Ethereum has expanded blob capacity. By January 2026, the network had reached a 14-blob target and 21-blob maximum per block, providing substantially more L2 data capacity than the original Dencun configuration.
Current 2026 blob-market snapshots also show periods of very low blob pricing, although the fee can change as demand changes.
The most important takeaway is that blob fees should be viewed as one component of L2 economics, not as the entire transaction fee.
Rollup execution, data compression, operator costs, proof-related expenses, and Ethereum’s broader data-availability capacity all influence what users ultimately pay.
Proto-Danksharding therefore represents not simply a fee reduction, but a change in how Ethereum prices and supplies the data-availability resource needed for rollup scaling.
