# Swarm ENS interface
|
|
|
|
## Usage
|
|
|
|
Full documentation for the Ethereum Name Service [can be found as EIP 137](https://github.com/ethereum/EIPs/issues/137).
|
|
This package offers a simple binding that streamlines the registration of arbitrary UTF8 domain names to swarm content hashes.
|
|
|
|
## Development
|
|
|
|
The SOL file in contract subdirectory implements the ENS root registry, a simple
|
|
first-in, first-served registrar for the root namespace, and a simple resolver contract;
|
|
they're used in tests, and can be used to deploy these contracts for your own purposes.
|
|
|
|
The solidity source code can be found at [github.com/arachnid/ens/](https://github.com/arachnid/ens/).
|
|
|
|
The go bindings for ENS contracts are generated using `abigen` via the go generator:
|
|
|
|
```shell
|
|
go generate ./contracts/ens
|
|
```
|
|
|
|
## Fallback contract support
|
|
|
|
In order to better support content resolution on different service providers (such as Swarm and IPFS), [EIP-1577](https://eips.ethereum.org/EIPS/eip-1577)
|
|
was introduced and with it changes that allow applications to know _where_ content hashes are stored (i.e. if the
|
|
requested hash resides on Swarm or IPFS).
|
|
|
|
The code under `contracts/ens/contract` reflects the new Public Resolver changes and the code under `fallback_contract` allows
|
|
us to support the old contract resolution in cases where the ENS name owner did not update her Resolver contract, until the migration
|
|
period ends (date arbitrarily set to June 1st, 2019).
