The recently trending "Dead or Alive" app looks like a lightweight implementation of the ancient security mechanism known as the Dead Man's Switch. In simple terms, it's a practical and straightforward little tool.

I first delved into this concept when I was immersed in the Arweave ecosystem. At that time, I was quite interested in the "Coffin Protocol" project, which also uses the Dead Man's Switch logic. To this day, the tokens issued by that project are still sitting in my wallet, and I can see the records on Coingecko.

Interestingly, a mechanism once discussed within a small circle has now become popular through a minimalistic app. This feels like the rhythm of Web3 innovation—good ideas always get rediscovered and popularized in some form at some point.
