Entities make up the core business concepts. If these entities change, they fundamentally change the entire app.
|
||||
|
||||
### Order
|
||||
|
||||
An Order Entity is nearly the same as an Offer. The Order is generated first, but is always internal to the bch-dex system. Most of the data in an Order is submitted to the P2WDB, which generates an Offer (external) Entity.
|
||||
|
||||
The Order tracks the [HD index address](https://github.com/bitcoinbook/bitcoinbook/blob/develop/ch05.asciidoc#hd-wallets-bip-32bip-44) used to hold tokens or BCH for sale. This is the part of the app concerned with the custody of the funds. It creates a segregated [UTXO](https://github.com/bitcoinbook/bitcoinbook/blob/develop/ch06.asciidoc#transaction-outputs-and-inputs) to hold the offered asset. The Order is automatically destroyed if the UTXO is spent.
|
||||
|
||||
Order entities have the following properties:
|
||||
|
||||
- Token Data:
|
||||
- _tokenId_ - The unique ID that identifies the class of token being offered for sale.
|
||||
- _utxoTxid_ - The TXID of the UTXO representing the token or BCH being offered for sale.
|
||||
- _utxoVout_ - The vout of the UTXO representing the token or BCH being offered for sale.
|
||||
|
||||
- Trade Data:
|
||||
- _buyOrSell_ - A string with a value `buy` or `sell` indicating which type of offer this is.
|
||||
- _numTokens_ - The maximum number of tokens offered for sale.
|
||||
- _rateInBaseUnit_ - The rate in terms of currency-unit-per-token. Ex: 1000 = 1000 sats per token
|
||||
- For Bitcoin, the min currency is sats.
|
||||
- For AVAX, the min currency is nano-Avax.
|
||||
- for eCash, the min currency is bits.
|
||||
- _minUnitsToExchange_ - The minimum order size accepted.
|
||||
|
||||
- Authentication Data:
|
||||
- _signature_ - A message signed by the address which created the order.
|
||||
- _sigMsg_ - The clear-text message used to generate the signature.
|
||||
- _offerBchAddr_ - The BCH address controlling the offer.
|
||||
- _offerPubKey_ - The public key used to generate the BCH address, used for encryption.
|
||||
|
||||
- Wallet Data:
|
||||
- _hdIndex_ - The HD index of the wallet used to generate the keypair to store the UTXO being offered for sale.
