Let’s Build the Tiniest Blockchain

This is not a blockchain. A blockchain needs a number of specific properties (see https://gist.github.com/joepie91/e49d2bdc9dfec4adc9da8a8434fd029b) to actually be a *blockchain*.

Your definition at the start of the article isn’t correct either;

> In more general terms, it’s a public database where new data are stored in a container called a block and are added to an immutable chain (hence blockchain) with data added in the past.

That describes a *public ledger*, not a blockchain. These are wildly different things. I feel like this article is based on a literal interpretation of the word “blockchain” without understanding the history or technical underpinnings of the concept.

By clapping more or less, you can signal to us which stories really stand out.
