graphical interface for utxo signature events: production, portrayal, and emission
A tool to assist in constructing and visualizing manual transactions. As parameters of the transaction are specified, the corresponding transaction hash is generated and updated dynamically. The transaction is also depicted in a chart, built in d3.js and updated in real-time.
The app requires a local instance of bitcoind to be running, and provides the option to sign and send the constructed transactions once they are complete.
Screenshots of the app can be found here, for those interested in looking but not using.
From the root directory, run:
sudo npm install
Once the required Node.JS modules have been successfully installed, modify app.js and update the port to your desired application port (default is 1234), the bitcoinCommandPath to your bitcoin-cli binary, and whether to use the testnet or mainnet:
port = parseInt(process.env.PORT, 10) || 1234,
bitcoinCommandPath = '/home/example/bitcoin-0.10.2/bin/bitcoin-cli ',
whichNetworkToUse = 'testnet';
Save the changes.
WARNING: the app will not work unless bitcoind is running.
When you have app.js updated and the modules installed, run the app with:
node app.js
Once the app is running, you can access the interface at http://localhost:1234
- Add a new sending (origin) address to begin. Once the node has been created corresponding to that address, it can be clicked to direct where its inputs should be sent.
- A "Fee" field allows the user to specify precisely what they will pay as a fee. All other leftover UTXOs are sent to the change address specified on the page.
- On app initialization, a change address is automatically generated for the page; this key can be imported into the local wallet with the Δ button.
- The "Gear" button will toggle the view of the transaction between a human-readable JSON string, and a raw transaction hash.
- The "Sign" button will sign a transaction that has been generated.
- The "Send" button will propagate a signed transaction to the network.
