# Abstract
|
||||
|
||||
This specification details what a Status account address is and how account addresses are created and used.
|
||||
|
||||
# Background
|
||||
|
||||
The core concept of an account in Status is a set of cryptographic keypairs. Namely, the combination of the following:
|
||||
1. a Waku chat identity keypair
|
||||
1. a set of cryptocurrency wallet keypairs
|
||||
|
||||
The Status node verifies or derives everything else associated with the contact from the above items, including:
|
||||
- Ethereum address (future verification, currently the same base keypair)
|
||||
- identicon
|
||||
- message signatures
|
||||
|
||||
# Initial Key Generation
|
||||
## Public/Private Keypairs
|
||||
- An ECDSA (secp256k1 curve) public/private keypair MUST be generated via a [BIP43](https://github.com/bitcoin/bips/blob/master/bip-0043.mediawiki) derived path from a [BIP39](https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki) mnemonic seed phrase.
|
||||
- The default paths are defined as such:
|
||||
- Waku Chat Key (`IK`): `m/43'/60'/1581'/0'/0` (post Multiaccount integration)
|
||||
- following [EIP1581](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-1581.md)
|
||||
- Status Wallet paths: `m/44'/60'/0'/0/i` starting at `i=0`
|
||||
- following [BIP44](https://github.com/bitcoin/bips/blob/master/bip-0044.mediawiki)
|
||||
- NOTE: this (`i=0`) is also the current (and only) path for Waku key before Multiaccount integration
|
||||
|
||||
# Account Broadcasting
|
||||
- A user is responsible for broadcasting certain information publicly so that others may contact them.
|
||||
|
||||
## X3DH Prekey bundles
|
||||
- Refer to [53/WAKU2-X3DH](/spec/53) for details on the X3DH prekey bundle broadcasting, as well as regeneration.
|
||||
|
||||
# Optional Account additions
|
||||
|
||||
## ENS Username
|
||||
- A user MAY register a public username on the Ethereum Name System (ENS). This username is a user-chosen subdomain of the `stateofus.eth` ENS registration that maps to their Waku identity key (`IK`).
|
||||
|
||||
## User Profile Picture
|
||||
- An account MAY edit the `IK` generated identicon with a chosen picture. This picture will become part of the publicly broadcasted profile of the account.
|
||||
|
||||
<!-- TODO: Elaborate on wallet account and multiaccount -->
|
||||
|
||||
# Wire Format
|
||||
|
||||
Below is the wire format for the account information that is broadcasted publicly.
|
||||
An Account is referred to as a Multiaccount in the wire format.
|
||||
|
||||
```proto
|
||||
message MultiAccount {
|
||||
string name = 1; // name of the account
|
||||
int64 timestamp = 2; // timestamp of the message
|
||||
string identicon = 3; // base64 encoded identicon
|
||||
repeated ColorHash color_hash = 4; // color hash of the identicon
|
||||
int64 color_id = 5; // color id of the identicon
|
||||
string keycard_pairing = 6; // keycard pairing code
|
||||
string key_uid = 7; // unique identifier of the account
|
||||
repeated IdentityImage images = 8; // images associated with the account
|
||||
string customization_color = 9; // color of the identicon
|
||||
uint64 customization_color_clock = 10; // clock of the identicon color, to track updates
|
||||
|
||||
message ColorHash {
|
||||
repeated int64 index = 1;
|
||||
}
|
||||
|
||||
message IdentityImage {
|
||||
string key_uid = 1; // unique identifier of the image
|
||||
string name = 2; // name of the image
|
||||
bytes payload = 3; // payload of the image
|
||||
int64 width = 4; // width of the image
|
||||
int64 height = 5; // height of the image
|
||||
int64 filesize = 6; // filesize of the image
|
||||
int64 resize_target = 7; // resize target of the image
|
||||
uint64 clock = 8; // clock of the image, to track updates
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
The above payload is broadcasted when 2 devices that belong to a user need to be paired.

||||
