Then there is also the cost of shifting out of Bitcoin. Note that these are the fields that are in a so-called raw transaction. It's also possible to require that an input be signed by ten different keys, or be redeemable with a password instead of a key. But it gets worse, because Bitcoin is not just another currency.

Technical Architecture

The technical problem that Bitcoin solves is to simulate a physical coin electronically, without relying on centralized administration. Therefore, a choice of privacy coins is available for anyone worried about the growing ability of governments to track crypto transactions. Perhaps this emergence of an infrastructure of cryptocurrency middlemen shows a certain maturation of the currency, just as banks inevitably grew up around currencies. Assuming that all other criteria are met see the previous section , then the transaction is a good one and it can be placed into a block.
