 Ethereum is a distributed network of computers (known as nodes) running software that can verify blocks and transaction data. The software application, known as a client, must be run on your computer to turn it into an Ethereum node.
 
-**Note: it is still possible to run an execution client on its own. However, this will no longer be possible after [The Merge](/upgrades/merge). After The Merge, both execution and consensus clients must be run together in order for a user to gain access to the Ethereum network. Some testnets (e.g. Kiln, Ropsten) have already been through their versions of The Merge, meaning execution clients alone are already insufficient for accessing those networks unless they are coupled to a consensus client that can keep track of the head of the chain.**
