TL;DR
- Bitcoin Cash undergoes a contentious hard fork on November 15, splitting into BCHN and BCHA chains as competing node implementations fail to reach consensus
- Ten days after the split, BCHN emerges as the dominant chain with over 80% of hash power, while BCHA struggles to maintain network security
- The fork centers on a dispute over the Bitcoin ABC client’s proposed 8% developer fund, which the BCHN node implementation rejected
- Major exchanges including Binance, Coinbase, and Huobi resume BCH deposits and withdrawals after confirming BCHN as the primary chain
- The event highlights fundamental governance challenges in decentralized blockchain networks where competing visions collide
Ten days after the Bitcoin Cash network underwent a contentious hard fork on November 15, 2020, the blockchain community continues to grapple with the fallout of a split that produced two competing chains: Bitcoin Cash Node (BCHN) and Bitcoin Cash ABC (BCHA). The divide has exposed deep governance challenges inherent in decentralized networks, raising questions about how blockchain projects resolve fundamental disagreements about their future direction.
The fork was triggered by a dispute over a controversial infrastructure funding plan proposed by Bitcoin ABC, the original Bitcoin Cash implementation. The plan would have directed 8% of all newly mined BCH to a developer fund controlled by ABC developers for a period of time. The BCHN implementation, backed by major mining pools and prominent community members, rejected the proposal as an unwarranted tax on miners and a centralizing force within the ecosystem.
Hash Power Battle Decides the Winner
In the days following the fork, the hash power contest between the two chains proved decisive. BCHN quickly accumulated over 80% of the total Bitcoin Cash mining hash rate, effectively establishing itself as the dominant chain. The BCHA chain, supported primarily by Bitcoin ABC developer Amaury Sechet and a smaller coalition of miners, found itself with insufficient hash power to maintain reliable block production.
Bitcoin Cash was trading around $312 on November 25, according to CoinMarketCap, reflecting the market’s ongoing assessment of the post-fork landscape. The split also generated BCHA tokens for holders of BCH at the time of the fork, though the value of the new asset remained highly uncertain as major infrastructure providers lined up behind BCHN.
Exchanges Pick Sides as Infrastructure Adapts
Major cryptocurrency exchanges played a crucial role in determining the outcome of the fork. Binance, Coinbase, Huobi, Kraken, and other leading platforms resumed Bitcoin Cash deposits and withdrawals after confirming that BCHN represented the continuation of the BCH ticker. Most exchanges credited users with BCHA tokens on a one-to-one basis, though trading support for the minority chain varied significantly across platforms.
Poloniex distributed both BCH and BCHA tokens to customers but kept wallets for both chains disabled while networks stabilized. Nexo announced it would support only the dominant BCHN chain, reflecting a broader industry trend of exchanges consolidating behind the hash-power winner rather than maintaining support for competing chains.
The exchange response highlighted an uncomfortable reality for blockchain governance: while the technology is designed to be decentralized, the practical resolution of chain splits often depends on the decisions of centralized intermediaries who control user access to their assets.
The Developer Fund Debate at the Core
At the heart of the Bitcoin Cash split lies a question that resonates across the entire blockchain industry: how should open-source blockchain development be funded? Bitcoin ABC’s argument centered on the need for sustainable funding to maintain and improve the protocol, pointing to the critical role that well-funded development teams play in blockchain security and innovation.
Opponents of the developer fund, however, viewed it as a form of centralization that contradicted Bitcoin Cash’s founding principles. The original Bitcoin Cash fork from Bitcoin in 2017 was driven in part by opposition to centralized decision-making, making the developer fund proposal particularly divisive within the community.
The debate mirrors similar discussions across the blockchain ecosystem. Ethereum, Cardano, Tezos, and other major platforms have all grappled with questions about how to fund ongoing development without compromising decentralization. The Bitcoin Cash fork demonstrates that these governance questions can have direct, material consequences for network participants.
Lessons for Blockchain Governance
The Bitcoin Cash split of November 2020 offers several important lessons for the broader blockchain technology space. First, it demonstrates that hash power remains the ultimate arbiter in proof-of-work blockchain disputes — the chain with more mining support prevails, regardless of the technical merits of either side’s arguments.
Second, the fork illustrates the tension between protocol development funding and decentralization principles. As blockchain networks mature, the question of how to sustainably fund development without creating central points of control will only become more pressing.
Third, the role of exchanges as de facto governance participants raises important questions about the relationship between decentralized protocols and the centralized infrastructure that provides user access. When exchanges choose which chain to support, they exercise significant influence over the outcome of governance disputes.
Why This Matters
The Bitcoin Cash hard fork of November 2020 is more than a historical footnote in cryptocurrency’s ongoing saga — it is a case study in the fundamental challenges of blockchain governance. As the industry continues to evolve and blockchain networks tackle increasingly complex technical and economic questions, the mechanisms by which communities resolve disagreements will determine which projects survive and which fragment. The BCHN-BCHA split demonstrates that even well-established blockchain networks with billions of dollars in market capitalization remain vulnerable to governance failures, and that the resolution of such disputes often depends more on power dynamics than on technical merit. For developers, investors, and users, the lesson is clear: understanding a blockchain’s governance structure is just as important as understanding its technology.

Amaury Sechet tried to tax miners 8% to fund his own team and got absolutely shellacked for it. BCABCHN hash ratio tells the rest of the story
the 8% developer fund was the whole controversy and BCHA couldn’t even maintain hash power to survive. says everything about which side miners actually backed
Brigitte F. the dev fund debate was actually nuanced. ABC wanted infrastructure funding, BCHN wanted no tax. both had valid points but hash power decided
BCHN getting 80% of hash power within 10 days made the result obvious. you can’t run a chain without miners no matter how good your governance argument sounds
the BCH split was the moment bitcoin maximalists pointed at as proof that hard forks destroy value. both chains are down massively vs BTC since november 2020
the real lesson from BCH is that developer funding through forced taxation never works. miners will always vote with their hash
reorg_skeptic miners voting with hash is not governance. its just power. BCH proved that whoever controls the hashrate controls the chain
8 pct developer mining tax was the real battleground. BCHN rejecting it was the only reason hash power consolidated that fast
BCHA surviving on 20 pct hash power for weeks after the split was honestly impressive. doomed project but the stubbornness was something else
Min-Jun L. BCHA surviving on 20pct hash for weeks was stubborn but also showed how cheap it is to keep a minority chain alive. the security budget was basically a rounding error
binance coinbase and huobi all confirming BCHN within days. the market settled this faster than most people expected
Chinedu O. Binance, Coinbase and Huobi all listing BCHN as the real chain within 72 hours. The market arbitrates these splits faster than any community vote
Chinedu O. three major exchanges confirming BCHN within days tells you the market picks winners faster than any governance process
the 8% developer fund was such a terrible idea. of course the miners rejected it
fork_witness is right. the 8% tax was framed as supporting development but it was really just funding ABC and sechets team directly. miners saw through it immediately
taxing miners 8% to fund development is basically asking them to fund their own competition. no surprise it got rejected
BCHN getting 80% hash power tells you everything about what the community wanted. ABC overplayed their hand
Dragan S. 80% hash power for BCHN was the community speaking. ABC tried to tax the network and got wiped for it
amaury sechet tried to strongarm the entire chain and it backfired spectacularly
sechet thought being the reference implementation author gave him ownership of the chain. the miners showed him otherwise
The Bitcoin Cash blockchain split exposes critical governance issues. Decentralized networks need clear governance frameworks to avoid hard forks like this.
This governance battle in BCH shows why Bitcoin Core’s conservative approach has maintained network stability over the years.
the 8% dev fund wasnt the only issue. ABC wanted control of the development roadmap and miners read that as a power grab
80% hash rate after 10 days shows what miners really wanted
8% dev fund split the whole community. governance by code vs governance by votes
coinbase listing made it official. BCHN was the clear winner from day one
