This is a public ledger that +anyone can read, however, it is supposed to be append only, meaning new +items only get added to the end of it, and the ledger in general can not +be modified. + +However, to have a ledger it needs to be located somewhere and +controlled by a central entity. This can be solved by actually having a +distributed ledger, so each user actually has their own version of the +ledger, and checks it periodically to the other ledgers that other +people are keeping. |
