Bitcoin Classic Emerges as 2MB Scaling Solution Amid Network Debate
TL;DR
- Bitcoin Classic proposes increasing block size from 1MB to 2MB to handle more transactions
- Major mining firms including BitFury, Bitmain, and Genesis Mining support the proposal
- Bitcoin Core developers advocate Segregated Witness instead, offering 4x capacity boost
- Chinese miners remain uncertain about which scaling approach to adopt
Following months of intense debate on how to scale the bitcoin network to accommodate a growing number of users, a new proposal called Bitcoin Classic has emerged with significant support from mining firms. The initiative aims to increase the block size limit from the current 1MB to 2MB, potentially doubling the network’s transaction capacity and addressing concerns about bitcoin’s ability to handle increasing user adoption.
The Scaling Challenge
The bitcoin network faces a critical scaling dilemma as more users adopt the cryptocurrency. With a hard-coded 1MB block size limit, the network can only process approximately three transactions per second. This limitation has become increasingly problematic as bitcoin gains mainstream attention and more merchants begin accepting digital payments. The debate centers on how to increase capacity while maintaining network security and decentralization.
Bitcoin Classic Proposal
Bitcoin Classic represents a straightforward approach to solving the scaling problem. If adopted, the protocol would double the maximum block size to 2MB, allowing roughly twice as many transactions to be processed in each block. This incremental increase aims to provide immediate relief to users experiencing slow transaction times and rising fees.
‘Bitcoin Classic is a fast answer,’ explained Alex Petrov, CIO of BitFury, one of the mining firms supporting the proposal. While other solutions involve more complex changes to the protocol, the 2MB block size increase offers a simple, immediate solution to the scaling challenge.
Industry Support
The Bitcoin Classic initiative has garnered significant backing from key players in the bitcoin ecosystem. On the development side, former Bitcoin Core maintainer Gavin Andresen has publicly endorsed the proposal, along with Bloq CEO Jeff Garzik and Ledger Journal editor Peter Rizun.
Major mining operations have also thrown their support behind Bitcoin Classic. BitFury, Bitmain, and Genesis Mining are among seven mining groups that have pledged support for the initiative. These miners believe that a direct increase to block size represents the most practical solution to scaling concerns.
The Bitcoin Core Alternative
The Bitcoin Core development team has introduced an alternative approach known as Segregated Witness (SegWit), which aims to increase transaction capacity without directly expanding block size. SegWit would increase capacity by approximately four times through improved transaction structure, but this solution requires more complex changes to the protocol.
Bitcoin Core’s roadmap suggests implementing SegWit before any direct block size increases, though this approach has faced criticism for its complexity and implementation timeline.
Industry Panel Consensus
The North American Bitcoin Conference (TNABC) featured a panel discussion where supporters of Bitcoin Classic made their case. FinalHash CTO Marshall Long described the proposal as ‘the most direct’ solution from a technological standpoint. Genesis Mining CEO Marco Streng emphasized that Bitcoin Classic directly addresses the current problem without unnecessary complications.
‘The transition with Bitcoin Classic can happen in a few weeks,’ said Yoshi Gato of Bitmain, highlighting the speed advantage over more complex solutions.
Miner Uncertainty
Despite enthusiasm from some mining firms, uncertainty remains regarding Chinese miners’ position on Bitcoin Classic. Reports suggest that Chinese mining operations may be wavering in their support, with some firms taking a wait-and-see approach. China represents a significant portion of bitcoin’s mining capacity, making the region’s stance crucial for any protocol changes.
Developer Position
Gavin Andresen, one of bitcoin’s most respected developers, has expressed support for multiple approaches to scaling, suggesting he may align with whichever solution gains broader market acceptance. This pragmatic stance reflects the developer community’s desire to maintain network unity despite philosophical differences.
Why This Matters
The block size debate represents one of the most significant challenges facing bitcoin’s long-term viability. The outcome will determine whether bitcoin can effectively scale to accommodate mainstream adoption or face continued limitations that could push users toward competing cryptocurrencies. Bitcoin Classic’s emergence as a credible alternative suggests that the market may ultimately favor solutions that prioritize immediate scalability improvements over more complex technical approaches.
As the network continues to evolve, the resolution of this debate will shape bitcoin’s trajectory and its ability to fulfill its potential as a global payment system and store of value.

alex petrov from bitfury was right that classic was the fast answer. problem was fast answers dont always survive in protocol development. segwit ended up being the better long term call
3 transactions per second with a 1MB block. no wonder fees were spiking and the community was panicking. the scaling debate was the most stressful period in bitcoin history
bitmain supporting classic was purely self serving. bigger blocks meant more revenue for their mining hardware. segwit threatened their asicboost advantage
genesis mining backing classic too. the mining firms were clearly coordinating around 2MB because it meant more transaction fee revenue for them in the short term
