The cryptocurrency world held its breath on November 16, 2017, as what could have been one of Bitcoin most contentious hard forks ended without activating, demonstrating the resilience of decentralized governance.
TL;DR
- SegWit2x hard fork cancelled November 8, 2017 due to lack of consensus
- Bitcoin maintained $7,871.69 price despite fork uncertainty
- 150+ SegWit2x nodes stopped accepting transaction blocks
- Regulatory community praised the decision as avoiding network fragmentation
The Failed Fork Timeline
The SegWit2x project, which would have increased Bitcoin block size to 2MB, began in August 2017 with support from major mining pools and exchanges. However, by November 8, 2017, the organizers announced the cancellation due to insufficient consensus within the community.
The fork was slated to occur on 16th November 2017, but was cancelled due to lack of consensus, according to Bitcoin Wiki documentation. This decision came after months of heated debate about Bitcoin scalability and governance.
Market Response to the Decision
Bitcoin market cap stood at $131.3 billion on November 16, 2017, with BTC trading at $7,871.69. The cryptocurrency had shown remarkable resilience throughout the fork uncertainty, with a 9.04% 7-day gain at the time of the fork cancellation.
Ethereum was also performing well, trading at $330.92 with a 2.84% 7-day gain. Meanwhile, Bitcoin Cash (BCH) experienced significant volatility, dropping 25.65% in 24 hours despite the SegWit2x cancellation.
Regulatory Implications
The SegWit2x cancellation sent important signals to regulators worldwide. Bitcoin showed its ability to self-correct and maintain network integrity without requiring external intervention. This demonstrated the maturity of decentralized governance mechanisms.
The Aftermath
After November 16, 2017, SegWit2x nodes were discovered to have stopped accepting transaction blocks. According to CoinDesk, as many as 150 nodes still running its code have stopped accepting transaction blocks. This prevented any accidental chain splits and maintained Bitcoin’s integrity.
Why This Matters
The SegWit2x failure established a precedent for decentralized decision-making in cryptocurrencies. It showed that even when major players push for technical changes, the community ultimately controls Bitcoin’s direction through consensus. This incident has been cited numerous times in subsequent blockchain governance discussions.
Furthermore, the incident demonstrated that regulatory concerns about Bitcoin network fragmentation were valid and that decentralized systems can resolve such issues organically, maintaining both security and market stability.

SegWit2x was the last real attempt by corporate interests to capture Bitcoin. 150 nodes stopped accepting blocks and the whole thing collapsed. UASF won
the fact that BTC held $7,871 after the cancellation showed the market did not want a contentious fork. smoother than anyone expected
BTC holding $7871 through the fork cancellation was the market saying loud and clear that nobody wanted a contentious split. the chaos was all on twitter not the charts
spot on. specifically about Bitcoin
UASF was the real turning point. users actually beat corporate interests in a governance fight. doesnt happen often in any industry
UASF proved that users can beat corporate miners. SegWit2x had Jihan Wu and Barry Silbert behind it and still lost. that result changed Bitcoin governance permanently
consensus_maximalist Jihan Wu and Barry Silbert had mining pools and corporate money and still couldnt force a 2MB block. users running full nodes said no. biggest W for bitcoin governance ever
consensus_maximalist Jihan Wu and Barry Silbert had mining power, exchanges, and corporate backing and STILL lost to a user revolt. UASF was the most important moment in bitcoin governance history
fork_witness_ dont forget Bitmain also ran the BCH chain simultaneously. Jihan had a fallback plan the whole time, SegWit2x was leverage for the fork they actually wanted
Anton M. Bitmain running BCH simultaneously is the detail everyone forgets. Jihan had SegWit2x as leverage and BCH as the fallback. the whole thing was negotiated in bad faith
yeah, Bitcoin really changed my perspective
its wild reading this now. 150 nodes stopped accepting blocks and SegWit2x just evaporated. try that kind of user revolt against a protocol change today
Niamh O. the difference is back then individual node operators actually mattered. now its data centers and institutions. the leverage shifted
fork_watcher_ individual node operators mattered in 2017 because running a full node was cheap. now with multi-terabyte chain data the leverage has shifted to data centers
node_operator_42 chain data is like 600GB now for BTC. try running a full archive ETH node, thats multiple terabytes. individual sovereignty requires individual hardware budgets now
Bitcoin market cap was $131.3B at the time and the entire fork drama barely moved the needle. compare that to how modern markets react to governance disputes
^this. another thing about 2017
131.3B market cap and BTC barely dipped through the fork drama. compare that to FTX where BTC lost 25% in days. says everything about which events were real risks vs twitter noise
131.3B market cap and BTC barely flinched. compare that to FTX where BTC dropped 25% in days. 2017 governance drama was priced as noise not existential risk
150 nodes shutting down and BTC barely moved. the market was pricing in the fork as pure downside risk so cancelling it was just relief. $7,871 was a floor not a ceiling
BTC holding $7,871 through the cancellation was the market’s way of saying the fork was priced as pure risk, not opportunity. no drama premium at all
Borys L. BTC holding 7871 through the cancellation was the market pricing fork risk at zero. the fact that it barely dipped told you users never wanted 2x blocks
SegWit2x cancelling was the moment Bitcoin proved it has no CEO. 150 nodes couldnt force a change the community didnt want
Sundeep Rao and yet BCH which actually forked for bigger blocks is worth a fraction of BTC. small blockers won on every metric
SegWit2x had Jihan Wu, Barry Silbert, and half the mining power and still lost. UASF proved users can beat corporate miners in a governance fight. most important moment in BTC history
BTC holding 7871 through the cancellation was the market saying nobody wanted a contentious split. compare that to BCH which forked anyway and is now irrelevant
