You can disclose your address to your friends so they can pay you and vice versa. In fact, using Bitcoin is quite comparable to Exchange e-mails with the exception that addresses Bitcoin should be used only once.

How does Bitcoin work?

Balances - chain blocks

The string of blocks is a general ledger shared and public on which rests the Bitcoin network as a whole. All confirmed transactions are included in the string of blocks. In this way, the Bitcoin portfolios can calculate their balances and it is possible to verify that new transactions spend bitcoins belonging actually to the issuer of the payment. The integrity and the chronological order of the chain of blocks are provided by cryptographic means.

Transactions - private key

A transaction is a transfer of value between portfolios Bitcoin which is included in the string of blocks. Bitcoin portfolios maintain a private key or seed called secret information that is used to sign transactions, providing a mathematical proof that they come from the owner of each portfolio. The signature prevents also changes the transaction after his show. All transactions are broadcast between users and usually start to be confirmed by the network in the following 10 minutes by a process called mining.

Treatment - mining

Mining is a distributed consensus system which is used to confirm pending transactions by including them in the chain of blocks. It imposes a chronological order in the chain of blocks, protects the neutrality of the network and allows different computers to be in agreement on the State of the system. To be confirmed, the transactions must be included in a block that must be very strict cryptographic rules which will be verified by the network. These rules prevent modification of a previous block because this would invalidate all the following blocks. Mining also induced the equivalent of a competitive lottery that prevents any individual to easily add blocks consecutively in the string of blocks. In this way, no individual can control what is included in the string of blocks or replace parts to cancel its own expenditure.

Go deeper into the adventure

For larger amounts as US $1,000, wait at least 6 confirmations is a good practice. Each confirmation exponentially decreases the risk of a reverse transaction.

IconBitcoin is still experimental
