Blockchain: The Complete Guide 

Possibly paywalled if your not a wired subscriber but this “Complete Guide” below is pretty well done if your not up for reading a full book yet.  If you are, a few resources linked to Amazon below that are more about the blockchain than bitcoin.

Start online though if you are new to it, plenty of free resources and great video’s on the internet for free.


“DEPENDING ON WHO you ask, blockchains are either the most important technological innovation since the internet or a solution looking for a problem.

The original blockchain is the decentralized ledger behind the digital currency bitcoin. The ledger consists of linked batches of transactions known as blocks (hence the term blockchain), and an identical copy is stored on each of the roughly 200,000 computers that make up the bitcoin network. Each change to the ledger is cryptographically signed to prove that the person transferring virtual coins is the actual owner of those coins. But no one can spend their coins twice, because once a transaction is recorded in the ledger, every node in the network will know about it.

 The idea is to both keep track of how each unit of the virtual currency is spent and prevent unauthorized changes to the ledger. The upshot: No bitcoin user has to trust anyone else, because no one can cheat the system.”
