Stellar Development Foundation held an open protocol discussion covering CAP 21 and CAP 40 approvals moving to final comment period, revised CAP 42 on multi-part transaction sets with validator fee control, and initial discussion of CAP 44 on SpeedX configuration for a decentralized exchange.
The Stellar open protocol meeting discussed the CAP lifecycle and advancement of two proposals. CAP 21 (transaction preconditions) and CAP 40 (new signer type) were approved by the CAP committee and moved to final comment period, enabling payment channels and cross-chain bridges. CAP 42 (multi-part transaction sets) was revised to clarify validator control over fee policies through execution phases and discounted rates, with discussion around social contracts for validator behavior and downstream system implications. CAP 44 (SpeedX configuration) introduced a new decentralized exchange design for batch trading at scale, with debate over whether validators or asset issuers should control which assets are included in SpeedX pools, and concerns about complexity and fairness in asset selection mechanisms.
