Bitcoin Blockchain chain structure

" I've been working on a new electronic cash system that's fully peer-to-peer, with no trusted third party..."

Satoshi Nakamoto said in his Bitcoin: A Peer-to-Peer Electronic Cash System whitepaper.

And then we had an idea of using the blockchain chain structure to confirm the transaction blocks and link together.

The Chain of black blocks represents the official blockchain, maintained by miner consensus. In order to compromise the chain, an attacker would have to extend one of the grey branches, making it longer than the black, "real" one. In order to do so they would have to outcompete the energy invested by all other miners on the black branch.

The grey blocks also called Extinct blocks or "Orphaned" are also valid blocks but which not part of the main chain. They can occur naturally when two miners produce blocks at similar times or they can be caused by an attacher with enough hashing power attempting to reverse transactions.

This structure is so classic and stands for blockchain so that We/BTCmusemu decided to make it as Necklace, and our blockchain ladies can wear it all day.
