Node Interaction

The DSL makes it easy to interact with bitcoin node with complete contract state available.

---

The DSL supports all JSON-RPC API commands supported by bitcoin. You don’t need to worry about (de)serialization of arguments. Just provide the transaction object or any other parameter directly from the DSL. Here are a few examples:

@address = ...

# Mine blocks to the address
generatetoaddress num_blocks: 100, to: @address

@tx = ...

# Send raw transaction
sendrawtransaction tx: @tx

Apart from providing access to the raw JSON-API commands, the DSL also provides commands that use the JSON-API to make life easier for a contract developer. For example, there are commands to extend chain and finding a spendable UTXO controlled by a key.
