Since this is the first week and no one has entered any exciting projects yet, The Stellar Daily Digest will be the featured app of the week… kidding… not kidding.

Seriously though, please enter your project here.

Updates to Stellar Protocol (CAPs) and Ecosystem (SEPs)

Core Advancement Proposals (CAP) and Stellar Ecosystem Proposals (SEP) are a formal way of documenting proposed standards to improve various aspects of the Stellar Network. These function similar to EIPs and BIPs from the Ethereum and Bitcoin communities respectively. CAPs and SEPs represent the culmination of many discussions that often take place on the Stellar Developer Google Group.

This week, 4 pull requests were merged to the protocols repository:

Most of the above are just updates to existing SEPs. However, David Mazières’s CAP-0021, named Generalized Transaction Preconditions, was merged, signalling its transition to the Draft phase (unfamiliar with the phases of protocol changes, see here). This CAP continues the recent theme of attempting to make state channels, like Starlight, easier and safer to implement. Specifically, this CAP: “generalizes the timeBounds field in Transaction to support other conditions, including conditions that relax sequence number checking and provide relative timelocks.” Read the finer details by clicking the link above.

Updates from Stellar Core

Stellar-core is the backbone of the Stellar network. It maintains a local copy of the ledger, communicating and staying in sync with other instances of stellar-core on the network. Stellar-core may also store historical records of the ledger and participate in consensus.

This week, 4 pull requests were merged.

Calls for Participation

Looking to get your hands dirty and not sure where to begin? The Stellar ecosystem is full of open source projects looking for help. The following projects are interested in some help and are very likely willing to offer mentorship in exchange:

Kelp (Go): a free and open-source trading bot for the Stellar universal marketplace

Solar (Typescript): Stellar wallet. Secure and user-friendly

Scala Stellar SDK (Scala): Scala SDK for the Stellar network

Stellar Go Monorepo (Go): Stellar’s public monorepo of go code

State of the Developer Ecosystem

This week we had a few version releases: Horizon (Go Monorepo) released a second 0.18.0 release client and the Swift SDK released v1.6.6 in preparation for the upcoming Horizon release.
