What Ports Does Bitcoin Close?86

Bitcoin is a decentralized digital currency, without a central bank or single administrator, that can be sent from user to user on the peer-to-peer bitcoin network without the need for intermediaries. Transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain. Bitcoin is unique in that there is a finite number of them: 21 million.
Bitcoins are created as a reward for a process known as mining, which involves solving complex mathematical problems. Miners are rewarded with bitcoins for completing blocks of transactions, which are added to the blockchain. The blockchain is a public ledger that contains all bitcoin transactions, and it is used to verify the validity of transactions.
Bitcoin is not controlled by any government or financial institution, and it is not subject to inflation or deflation. The value of bitcoin is determined by supply and demand, and it has been highly volatile in the past.
Bitcoin can be used to purchase goods and services from a growing number of merchants, and it can also be traded on cryptocurrency exchanges. Bitcoin is not legal tender in any country, but it is recognized as a valuable asset by many investors.
