Key Insights
- The Cardano network experienced a slowdown in block production for over an hour on November 21 due to parallel forks running across different node versions.
- Intersect coordinated with Cardano Foundation and Input Output to resolve the issue, advising node operators running version 10.3.1 or higher to upgrade to version 10.5.2.
- Technical analysts identified $0.30 as a critical support level for Cardano’s price, with some traders citing bullish divergence on the daily charts.
Cardano-focused wallet Vespr reported on November 21 at 8:42 am UTC that the network appeared to experience downtime, with no blocks produced for over 20 minutes.
The wallet provider noted that transactions made through any platform would not be processed until network activity resumed.
Nearly an hour later, Vespr stated that Cardano (ADA) network activity had resumed to some capacity but had not fully recovered.
The situation remained under monitoring as the community assessed the extent of the disruption.
Network Fork and Node Version Discrepancy
Intersect, a member-based organization for the Cardano ecosystem, explained the technical issue at 10:39 am UTC on November 21.
Following a problem identified in the Preview environment the previous day, the Cardano mainnet experienced a technical disruption that slowed block production.
The organization worked closely with Cardano Foundation and Input Output to coordinate a technical response.
Intersect issued specific guidance to node operators. Those running node version 10.3.1 or higher received instructions to upgrade to Cardano Node 10.5.2 through the GitHub repository.
Operators running versions below 10.3.1 did not need to take action, and Daedalus wallet users remained unaffected by the issue.
A user identified as Paddy said on X that Cardano had not completely stopped. Node version 10.1.4 halted.
However, users running newer versions continued to run, with what observers described as a “ghost chain” continuing. A user provided an example of version 10.4.1 relay operating normally.
Block explorer Cexplorer confirmed blocks continued to be produced throughout the period, though block propagation experienced some disruption.
Vespr later said it appeared that two forks were running in parallel, with uncertainty about which would become the final Cardano chain.
The incident represented a version fragmentation issue rather than a complete network halt.
Different node versions processed blocks separately, creating temporary parallel chains until operators upgraded to compatible versions and consensus reconverged on a single chain.
Cardano (ADA) Price Support at $0.30
Trader Ali Martinez shared an analysis on November 21, identifying $0.30 as a potential support level for Cardano.
A chart accompanying the analysis showed ADA price action throughout 2024, with horizontal support and resistance levels marked.
The chart highlighted previous price reactions at the $1, $0.74, $0.64, and $0.54 levels, with arrows indicating past bounces and rejections.
The analysis suggested that the ADA price could find support near $0.30 if downward pressure persisted.
Historical price action on the chart showed that $0.30 had served as an accumulation zone earlier in the year, before the rally that pushed prices above $1 in March.
Trader VivaLaCoin shared a similar perspective on the same day, stating an “Anti-Buy High” approach maintained since early 2022.
The trader indicated a willingness to accumulate Cardano below $0.30, with stronger interest at levels 50% below that threshold.
A chart displayed a descending wedge pattern from peak prices above $1.20 down to current levels around $0.40, with the trader noting 2025 had been “a game of patience” despite broader market sentiment.
Bullish Divergence Technical Setup
Trader Deezy outlined a bullish technical case for the Cardano price based on divergence patterns on the daily chart.
The analysis identified two instances of bullish divergence: the ADA price made lower lows. In comparison, the Relative Strength Index made higher lows, a pattern typically interpreted as a momentum shift signal.
The chart showed the first bullish divergence occurred in February-March 2024 near the $0.60 level, preceding a rally that delivered approximately 100% gains.
A second bullish divergence appeared to form in the current price action around the $0.46 level in November, with RSI showing higher lows than in the March period.
The technical setup suggested potential for upside movement if the pattern repeated historical behavior.
However, ADA price would need to hold above the identified support zones near $0.30 for the bullish scenario to remain intact.
Cardano (ADA) price traded at $0.4210 following the resolution of the network issue, down 2.52% on the day.
The combination of technical support levels around $0.30 and potential bullish divergence patterns created a watch point for traders monitoring whether ADA price could stabilize and reverse recent downward momentum.
