Providers
=========


A **Provider** is an abstraction of a connection to the
Ethereum network, providing a concise, consistent interface
to standard Ethereum node functionality.

The ethers.js library provides several options which should
cover the vast majority of use-cases, but also includes the
necessary functions and classes for sub-classing if a more
custom configuration is necessary.

Most users should be able to simply use the [Default Provider](./).


Default Provider
----------------


The default provider is the safest, easiest way to begin
developing on *Ethereum*, and it is also robust enough
for use in production.

It creates a [FallbackProvider](other) connected to as many backend
services as possible. When a request is made, it is sent to
multiple backends simulatenously. As responses from each backend
are returned, they are checked that they agree. Once a quorum
has been reached (i.e. enough of the backends agree), the response
is provided to your application.

This ensures that if a backend has become out-of-sync, or if it
has been compromised that its responses are dropped in favor of
responses that match the majority.


#### *ethers* . **getDefaultProvider** (  [ network ]  )  **=>** *[Provider](provider)*

Returns a new Provider, backed by multiple services, connected
to *network*. Is no *network* is provided, **homestead**
(i.e. mainnet) is used.
