Nvidia shares rise 2.5% amid optimism over US-China trade relations

Cardano faced an unexpected shock when a corrupted transaction aimed at 
Charles Hoskinson’s personal stake pool caused the network to split for 
several hours. The incident triggered confusion, exposed weaknesses, and 
sparked a heated clash over motive and responsibility. Here is how a single 
action spiraled into a full-scale disruption. Cardano Founder Targeted, 
Network Shaken The Cardano network faced unexpected disruption on November 21, 
2025, after an incident targeting the founder’s personal stake pool. What 
began as a ‘test’ by a stake pool operator quickly escalated into a risky 
experiment on the main network, where he reportedly followed unverified AI- 
generated instructions and submitted a malformed transaction. Related Reading:

transaction exploited an obscure 2022 cryptographic library bug, causing newer 
nodes to parse it incorrectly while older nodes rejected it. This triggered a 
chain split, disrupted block production, and left validators, DeFi protocols, 
and everyday users struggling to stay aligned for several hours. The operator 
later admitted that the entire situation was the result of poor judgment, one 
he described as a personal challenge he handled recklessly. He insisted he had 
no financial motives, no collaborators, and no intention to target the 
founder. His message expressed regret for the disruption caused to stake pool 
operators and developers who had to react immediately. Many operators lost 
block rewards, and some decentralized applications experienced inconsistent 
states. While user funds remained safe, the event revealed how one misstep 
could trigger a chain-wide disturbance. Hoskinson Says It Was Personal And 
Months In The Making Despite the stake pool operator claiming no intention of 
harm, Cardano founder Charles Hoskinson rejected the idea that this was an 
accidental mistake. He stated that the individual responsible had been active 
in online groups known for hostility toward Cardano and its leadership. 
According to him, the attacker had spent months discussing ways to disrupt the 
project’s operations and reputation. Hoskinson pointed out that his personal 
pool was the direct target. For him, this proved the act was intentional, not 
an experiment gone wrong. He emphasized that the disruption touched every user 
on the network, causing stake pool operators to miss earnings, parts of the 
DeFi ecosystem to stall, and Cardano developers to be forced into rapid 
emergency fixes. Related Reading: Barstools Founder Just Made A Million-Dollar

had already stepped in, turning the event into a criminal matter. In his view, 
the public apology surfaced only after community investigators linked the 
operator to the incident and federal involvement became clear. The incident 
left the community divided between two narratives: one of reckless 
experimentation and one of calculated sabotage. What remains certain is that a 
targeted hit—intentional or not—exposed how quickly a malformed transaction 
can fracture the system and force an entire ecosystem into crisis mode. 
Cardano recovered, but the questions raised by this attack will continue to 
shape how the network prepares for the next potential threat. Featured image
