=== Transaction Gas

((("gas","transactions and", id="ix_06transactions-asciidoc3", range="startofrange")))((("transactions","gas", id="ix_06transactions-asciidoc4", range="startofrange")))We talked about gas a little in earlier chapters, and we discuss it in more detail in <<gas>>. However, let's cover some basics about the role of the +gasPrice+ and +gasLimit+ components of a transaction.

Gas is the fuel of Ethereum. Gas is not ether&#x2014;it's a separate virtual currency with its own exchange rate against ether. Ethereum uses gas to control the amount of resources that a transaction can use, since it will be processed on thousands of computers around the world. The open-ended (Turing-complete) computation model requires some form of metering in order to avoid denial-of-service attacks or inadvertently resource-devouring transactions.

The Ethereum protocol does not validate recipient addresses in transactions. You can send to an address that has no corresponding private key or contract, thereby "burning" the ether, rendering it forever unspendable. Validation should be done at the user interface level.
====

((("ether burn")))Sending a transaction to the wrong address will probably _burn_ the ether sent, rendering it forever inaccessible (unspendable), since most addresses do not have a known private key and therefore no signature can be generated to spend it. It is assumed that validation of the address happens at the user interface level (see <<EIP55>>). In fact, there are a number of valid reasons for burning ether&#x2014;for example, as a disincentive to cheating in payment channels and other smart contracts&#x2014;and since the amount of ether is finite, burning ether effectively distributes the value burned to all ether holders (in proportion to the amount of ether they hold).
