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.
