We have one new CAP to discuss and that is CAP-80. This proposal adds BN254 Multi-Scalar Multiplication and modular arithmetic used in a variety of ZK proof applications. Adding host support for these will greatly improve the performance of these use cases.
We also follow up on a previous CAP - the CAP-73.

In this year’s first Stellar Developer Meeting, on Thursday, January 22nd at 8am PT on Twitch, we will catch up with Ozgun and Boyan from the OpenZeppelin team and take a look at the libraries released in Q4 last year.
We had three CAPs prepared for this meeting. CAP-77 will provide a way to make ledger keys inaccessible based on the network configuration upgrade performed with a validator vote. CAP-78 proposes an interface which allows developers to specify TTL extension policies such as 'if an entry TTL is less than 29 days, extend it to have 30 days TTL'. CAP-79 introduces host functions for converting Stellar strkey format strings to/from Address/MuxedAddress objects.

In this meeting we do a walkthrough of OpenZeppelin’s Q3 library releases for Smart Account, Vault and RWA.

In this meeting we are continuing our mini series about the Stellar-based open source tooling OpenZeppelin is developing. In the last session we talked briefly about Relayer and this time we are diving deeper into this tool, and OpenZeppelin Managed Service.

In this meeting we are talking to Dobprotocol to learn more about how they use Stellar to build a unique platform, turning machines into investable assets.

In this call the recent state archival issue, introduced by Whisk (Protocol 23), is discussed. Questions from community builders are also answered.
We are meeting with the OpenZeppelin team again to catch up on the latest developer tooling work they are doing.
This time Steve will demo UI Builder, an easy way to spin up a front-end for any contract call in seconds. UI Builder allows you to select a function and then it auto-generates a React UI with wallet connect and multi-network support, and exports a complete app.
In this Core Advancement Proposal discussion CAP-0075 (Host functions for enabling Poseidon and Poseidon2 hash functions) is presented.
This CAP proposes adding host functions for cryptographic primitives enabling Poseidon family of hash functions, which are widely-adopted hash choices in efficient zero-knowledge proof systems. Supporting these as host functions in Soroban can facilitate adoption of ZK applications and interoperability with other ecosystems.

In this meeting we will discuss CAP-74, BN254 and Poseidon hash functions.
In this week’s Stellar Developer Meeting we discuss new Core Advancement Proposals.
Here are some resources to read up on:
In this meeting we talk to Flashback founder Brieuc Berruet, who participated in the DraperU x Stellar incubator program last year, to get an update on his project (spoiler alert - it's live!).
Learn more about the project, and see a cool demo!
In this meeting we are talking to Esteban and Francisco from PaltaLabs. Stellar Hacks is currently running a hackathon in collaboration with PaltaLabs, where the goal is to build using their projects Soroswap and DeFindex.
Let's see how the hackathon is going, and some advice if you are still considering entering, there's still time to enter!

In this meeting the Nomyx team will give us an introduction to their advanced smart contract architecture (an implementation of the Diamond Pattern) and the Nomyx Diamond proxy viewer interface, that facilitates inspection of deployed diamonds and makes them a bit easier to work with.
They will also be showcasing a live deployment instance of the diamond proxy standard currently used for the Nomyx platform which removes limitations related to the upper contract size limit, allowing developers to launch complex products.
