Hi there,
I got some requests to re-record the tutorial talk I gave at DevCore 2015,
"How to build a timestamping smart contracts app in 30 minutes". It's now
available here:
https://bitcoinj.github.io/document-timestamp-app
It covers:
- How to customise the wallet-template app for this use case
- How to construct a complex multi-stage SPV proof of block chain
inclusion
- How to save and then verify proof files
- How to bind transaction confidence state to the user interface
- How to create a Mac DMG bundle with a custom icon
I hope someone finds it enjoyable!
