George from SDF's Horizon team demonstrates how to use Stellar SDKs by building a game that decodes XDR transactions, claims claimable balances, and streams payments as incoming attacks. The talk covers the three-layer SDK abstraction pyramid: cryptography/XDR, transaction building, and Horizon API querying.

Lee McCulloch and Alex Sharbena from the Stellar Development Foundation presented Starlight, a layer-2 payment channel protocol enabling millions of transactions per second off-chain while maintaining security through CAP-21 and CAP-40 protocol upgrades.

Marta Lakova explains StellarCore's architecture, covering the consensus protocol, ledger state management, and how data flows across the Stellar network. The presentation details how StellarCore maintains distributed agreement on transactions, closes ledgers every five seconds with finality, and enables new nodes to catch up via history archives.

Austin Rice and Marta Lakova from the Stellar Development Foundation deliver a technical deep dive into how Stellar works, comparing its federated Byzantine agreement consensus to Bitcoin and Ethereum's proof of work, then demonstrate asset issuance on the Stellar testnet using Stellar Laboratory.

Stellar Open Protocol discussion on CAP 21, which enables payment channels on Stellar for off-chain transactions and improved network throughput. The CAP is moving forward to the committee for approval after technical revisions and validation experiments.

Stellar Open Protocol meeting reviewing CAP 38 (Automated Market Makers) post-implementation changes. The team validated final XDR adjustments before protocol 18 network upgrade scheduled for November 3rd, confirming AMM functionality is ready for deployment.

Stellar Development Foundation discusses CAP 21, a core advancement proposal that enables payment channels on Stellar. The team addresses outstanding technical questions about account extensions, transaction validation, and preconditions to move toward acceptance.

Stellar Open Protocol meeting discussing CAP 21 and CAP 40, which lay groundwork for payment channels. CAP 21 generalizes transaction preconditions to support relative time locks and other conditions; CAP 40 enables participants to exchange signatures for multiple transactions in one step.

Stellar Development Foundation held an open protocol discussion on CAP 37 and CAP 38, two competing proposals to introduce automated market makers (AMMs) at the protocol level. After extensive debate on implementation approaches, the CAP committee unanimously voted to move CAP 38 into final comment period, choosing the simpler best-venue routing model over CAP 37's more complex interleaved approach.

Tyler Vanderhoeven from SDF walks through Stellar development fundamentals, covering the Stellar stack, SDKs, transaction building with JavaScript, and delegated signing with Albedo wallet for non-custodial key management.

Anke from SDF presents a workshop on Stellar fundamentals, covering blockchain basics, how Stellar works, asset issuance, the decentralized exchange, and real-world applications like Uhuru Wallet and Leaf Global Fintech. The session includes live demonstrations using Stellar Laboratory and highlights a $3,000 hackathon prize pool for projects solving real-world problems.

Stellar protocol discussion on automated market makers (AMMs) focusing on asset authorization and revocation mechanisms. Two approaches debated: one mirroring existing offer revocation semantics, another requiring issuer opt-in for liquidity pool participation.

Stellar developers discussed two competing proposals, CAP 37 and CAP 38, for adding automated market makers (AMMs) to the protocol. Key topics included reserve requirements, DEX integration approaches, pool parameter updates, and governance for multiple pools per asset pair.

Tim Berners-Lee, inventor of the World Wide Web, discusses Solid, a decentralized protocol for data ownership and control. He draws parallels between early web principles and current blockchain/Stellar efforts, emphasizing the importance of open standards, user agency, and avoiding centralization.

Stellar Development Foundation engineers and ecosystem validators discuss network decentralization, node operations, and tier one validator requirements at Meridian conference. Speakers cover quorum set configuration, incentive structures, and the path to becoming a tier one validator.

Tomer Weller from SDF traces the six-year evolution of Stellar anchor interoperability standards, from 2014 gateways through SEP6, SEP24, and SEP31, explaining how anchors bridge traditional finance with Stellar and enable cross-border payments.

David Mazuris introduces STC, the Stellar Transaction Compiler, a command-line tool that makes it easier to create, examine, and debug raw Stellar transactions without writing code. The tool translates between XDR and TxRep formats, enabling developers to test transaction behavior directly on the network.

Tyler Vanderhoeven from SDF presented progress on Turing Signing Servers, a proposal for enabling decentralized transaction creation on Stellar through programmable smart contract-like functionality without modifying the core protocol.

Jake Urban from SDF presents Polaris, an extendable Django application that simplifies building modular Stellar anchor services. Polaris implements common anchor functionality while allowing developers to customize and extend it for their specific needs, supporting SEP 6, 24, and 31 protocols.

Lee McCulloch from SDF explains SEP-30, a Stellar Ecosystem Proposal that enables user-friendly account recovery without requiring users to manage secret keys. The protocol uses multi-signature accounts and independent recovery servers, demonstrated by Vibrant wallet in Argentina.

Stellar Development Foundation hosted an open protocol meeting to discuss CAP 21, a draft proposal for generalized transaction preconditions. The CAP aims to enable payment channels, relative time locks, and time-delayed key recovery by extending account entries and replacing the time bounds field with more flexible preconditions.

Stellar protocol developers discussed CAP 35, which enables asset issuers to claw back tokens for regulatory compliance. The proposal moved from draft to final comment period after minor revisions including deprecating AllowTrust and expanding asset parameters for future delegation flexibility.

Devnil from SDF's Voyager team presents the first version of Stellar's data analytics system, built on BigQuery and Kubernetes to enable fast historical queries and network insights. The system powers internal business analytics and will soon support real-time data, improved observability, and public visualizations.

Stellar Development Foundation launches SCF 2.0, splitting the Stellar Community Fund into two distinct funds: a 500k Lumen lab fund for experimental projects (4x yearly) and a 5M Lumen seed fund for viable businesses (2x yearly). The redesign introduces panel judges for initial filtering and flaggable quadratic voting to better allocate funds based on community sentiment.
