8ball
Decolonise colons!
Each new block is a record of who has what. Updated as you say at every node in the system so it can't be cheated (although this is also a weakness in that it creates limits on the size of the block). Mining releases blocks. Currently each block has 12.5 more bt on it than the previous one, with those 12.5 bc credited to the account of whoever mined the block.
Do you mean each block is originally credited to whomever mines it, and then it gets traded, adding information to the block?
