In this monthly feature we highlight a selection of the transcripts from the previous month.* + +* **Simplicity - Next-Gen Smart Contracting** Adam Back presented at a Blockstream webinar on Simplicity: a next generation, low level alternative to Bitcoin Script focused on provable security and greater expressiveness. Back discussed how Simplicity, if enabled in Bitcoin today, would allow developers to implement new functionality like SIGHASH_NOINPUT without necessarily needing a soft fork. He also displayed a [demo](https://asciinema.org/a/rhIsJBixoB3k8yuFQQr2UGAQN) showing what you can do with Simplicity today.

She discussed the dangers of network partitions and eclipse attacks and explained why block-relay-only connections and anchor nodes are effective mitigations.

Osuntokun presented a new channel feature called anchor outputs to address the challenge of estimating onchain fees months in advance in addition to Tor and RPC enhancements in the latest release of lnd. Jager discussed the challenges of multipart payments including the splitting algorithm, what happens when the shards of the payment arrive at different times and strategies for when a multipart payment fails. Gugger ended by discussing PSBT channel funding and the channel abstraction work that made this possible.

The Socratic Seminar in the previous week focused on the role of Bitcoin technical education, HD wallets and soft fork upgrades.
