Cardano showcasing network resiliency after a close call
A few hours ago over half of all #Cardano nodes went offline. This is why decentralization matters.

What happened?
Recently, the Cardano network faced a hiccup when over half of its nodes went offline for a brief period.
The incident, which occurred on 22.01.2023 at 00:09:00 UTC between block 8300569 and 8300570, was caused by a transient anomaly that affected relay and block-producing nodes. However, edge nodes appeared to be unaffected.
It was triggered by a transient anomaly causing one of two reactions in the node; some disconnected from a peer, and others threw an exception and restarted.
What exactly caused this network hiccup?
From early analysis, the event was caused by a transaction bug.
Cardano has recovered from the node outage a couple hours ago. But early investigation suggests a single tx may have been responsible. If an adversary learns how to recreate this tx... This needs to be fixed ASAP.

According to Andrew Westberg, a veteran stake pool operator with extensive experience, the root cause would be difficult to find as the data related to the event is likely gone.
How the incident affected the network and its users?
Although the incident caused a temporary interruption in block production and resulted in a portion of the network falling out of sync, IOG stated that the systems performed as anticipated.
And the overall impact on the network was minimal, similar to delays that can occur during regular operations and at epoch boundaries.
The real takeaway for me is how impressively resilient the cardano network is. Something took down ~60% of nodes and the network recovered in a few minutes, and continued producing blocks throughout.

Discussions around the Ouroboros Genesis in the context of network hiccup
Although the network recovered from the event quickly without any serious impact, there were discussions about the capabilities that Ouroborus genesis could bring during such a future event.
Introduction to Ouroboros Genesis
Ouroboros Genesis is the next anticipated upgrade that introduces a property known as Dynamic Availability to Cardano.
This feature allows the chain to automatically adjust and maintain security in the event of a drastic change of network participation, such as an outage.
The protocol is designed to address one of the main challenges faced by PoS-based blockchain protocols, which is the inability to realize the ledger functionality under dynamic availability in the same way that Bitcoin does (using only the information available in the genesis block).
How Ouroboros Genesis Works?
The Ouroboros Genesis introduces a novel chain selection rule.
The rule enables new or offline parties to safely (re-)join and bootstrap the blockchain only from a trusted copy of the genesis block without any additional advice or assumptions regarding past availability.
This means that even if a large number of nodes went offline, the network would be able to adjust and remain secure. The protocol is also designed to be independent of both the maximum network delay and the minimum level of availability, making it more resilient to outages.

💎 Gem of the Day 🧵
Every Cardano stake pool has a special key on it that evolves every 36 hours.
It's called a Key Evolving Signature or KES.
After 62 evolutions (~90 days) it stops working and needs to be regenerated.
This prevents certain attacks & keeps the SPO on their toes!
