00:50:01 LDK Roadmap
Several features are underway such as LDK Node, BOLT 12, Anchor Outputs, Async Payments, VSS, Taproot, and more. Other projects will start soon or need contributors
VSS (Versioned Storage Service) addresses two problems and will be split into two development phases. First, it offers a cloud backup for encrypted LN state and other wallet data. Second, VSS will enable support for multi-device access to the same wallet.
LDK devs provided feedback to the Taproot protocol spec and are close to finalizing simple Taproot channels.
The async payments proposal will substantially improve the mobile wallet user experience by allowing people to receive payments under any conditions. Work will be broken down into two phases; async receive and async send.
Other 2023 projects include PTLCs, dual-funded channels, splicing, anchor outputs, and BOLT 12. Over time more async support will be added throughout the LDK API. Potential future projects include additional language bindings, custom scripts, and dynamic commitments.

01:19:32 Bitcoin Jungle
Helping bring the Bitcoin ecosystem to Costa Rica. The Bitcoin Jungle wallet app is wallet built on top of the Bitcoin and Lightning Networks. Based on a similar model as BitcoinBeach, it uses the Banking-As-A-Service infrastructure from Galoy.
Bitcoin Optech Newsletter
Notable code and documentation change: Bitcoin Core #25943 adds a parameter to the sendrawtransaction RPC to limit the amount of funds burned per output. If the transaction contains an output whose script is heuristically deemed to be unspendable (one with an OP_RETURN, an invalid opcode, or exceeding the maximum script size) and whose value is greater than maxburnamount, it will not be submitted to the mempool. By default, the amount is set to zero, protecting users from unintentionally burning funds.
News: Alternative design for OP_VAULT: Greg Sanders posted to the Bitcoin-Dev mailing list an alternative design for providing the features of the OP_VAULT/OP_UNVAULT proposal (see Newsletter #234). His alternative would add three opcodes instead of two.
