 <p>A transaction is <b>a transfer of value between Bitcoin addresses</b> that gets included in the block chain. Bitcoin wallets keep a secret piece of data called a <a href="/en/vocabulary#private-key"><i>private key</i></a> for each Bitcoin address. Private keys are used to sign transactions, providing a mathematical proof that they come from the owner of the addresses. The <a href="/en/vocabulary#signature"><i>signature</i></a> also prevents the transaction from being altered by anybody once it has been issued. All transactions are broadcast between users and confirmed by the network in the following minutes, through a process called <a href="/en/vocabulary#mining"><i>mining</i></a>.</p>
 
 <h2>Mining</h2>
-<p>Mining is a <b>distributed consensus system</b> that is used to <a href="/en/vocabulary#confirmation"><i>confirm</i></a> waiting transactions by including them in the blockchain. It enforces a chronological order in the blockchain, protects the neutrality of the network, and allows different computers to agree on the state of the system. To be confirmed, transactions must be packed in a <a href="/en/vocabulary#block"><i>block</i></a> that fits very strict cryptographic rules that will be verified by the network. These rules prevent any previous block from being modified because doing so would invalidate all following blocks. Mining also creates the equivalent of a competitive lottery that prevents any individual from easily adding new blocks consecutively in the blockchain. This way, no individuals can control what is included in the blockchain or replace parts of the blockchain to roll back their own spends.</p>
