TEZOS TEZOS
===== =====
Tezos is a distributed consensus platform with meta-consensus capability. Tezos
not only comes to consensus about state, like BTC or ETH. It also comes to
consensus about how the protocol and the nodes should adapt and upgrade.

Create a new switch alias for Tezos. A switch is your own version of the OPAM
configuration, including the OCaml compiler, all packages, and package manager
configuration related to your project. This is necessary so that the project
doesn't conflict with other OCaml projects or other versions of Tezos.
```

Activate the new switch:
```
