In the final session on day one, attendees were asked to split up and brainstorm how nLockTime transactions and Bitcoin contracts could be used in real-world use cases.

NLOCKTIME AND DELAYED TRANSACTIONS
Session1:
Creating Time-Locked Transaction Paths Securely
If you have any questions, please email them to events@nchain.com
This session will explore the various ways that individuals can create time-locked transactions between one or
more entities, using a variety of different script constructs where the transactions are secure, and implement a
message to allow for the future control of events for time-based systems.

Session2:
Integrating Payment Channels and nLocktime
If you have any questions, please email them to events@nchain.com

Session3:
Conflicts with Alternative nLocktime
If you have any questions, please email them to events@nchain.com
