The Bitcoin node is a pivotal part of the Bitcoin (BTC) protocol. For bad actors, attacking nodes and making them offline is a sound strategy for undermining network resilience. For a British Bitcoiner client, such an attack occurred, in which the actions of his cunning friend made his Bitcoin node “unreachable”.
Bodl_hodler (who wishes to remain anonymous) told Cointelegraph that he “launched the Raspberry Pi as an Umbrel node in January 2021,” as he wanted to contribute to the overall decentralization of the Bitcoin network.

The node has been running smoothly since the connection, confirming Bitcoin blocks on average every 10 minutes according to the difficulty adjustment. However, in late May 2022, when the price began to drop below $30,000, “Boodle went to log into the node for the first time in a while and was not found on the network.”
“So I pulled it up from behind the sofa only to find it was covered in a crusty layer of bread baked on a sick cat.”
To his horror, the Poodle discovered that his big black cat, Pablo, had vomited on the Bitcoin knot. The “dirty invocation” affected a node’s ability to connect to the Internet and run. Puddle explains, “The vomit passed from the vents and stopped the knot.”

In fact, if a Bitcoin node goes offline, it can no longer contribute to the security of the network, potentially compromising the Bitcoin protocol. “Maybe he (Pablo) mistakenly thought he was running a dog-themed Chetcoin,” Poodle joked, and “couldn’t stand the volatility.” Bodl is a Bitcoin cap and has no time for the likes of Dogecoin (DOGE).

Fortunately, it is also very easy to restart node and pick up the missing blocks. Poodle said he “removed the power, plugged it back in, and luckily it ran fine and took a few minutes to re-sync to add up all the blocks I missed.”
The node was immediately brought back to life, confirming transactions and securing the network. “Tick tock, next block,” has become a popular phrase among nodes runners due to the regularity of bitcoin blocks.
Incidentally, operating a BTC node is becoming increasingly easy and allows Bitcoin users to easily verify their transactions. Bitcoin enthusiasts can now run a Lightning contract while some hope to earn passive income along the way. As for Pablo, he now has a new cat company called Lottie which recently joined the Poodle family.
