PLF+PLAID 2025 is a joint effort combining two workshops from previous years:
PLF (Programming Local-first Software) and PLAID (Principles, Theory, and
Practice for Decentralized Applications). The two workshops had significant
overlap in their topics, and we aim at bringing together their communities of
researchers and practitioners. Talk proposals suitable for either of the
earlier workshops are well-suited for PLF+PLAID.
# ABOUT
Ubiquitous connectivity and the affordable availability of user devices,
ranging from smartphones to desktops, have made applications that support
multi-device and collaborative use increasingly common. These devices and the
networks they belong to possess vastly different characteristics. Data centres
offer near-unlimited resources and high availability, while edge devices often
have limited resources, experience frequent connectivity loss, and display
significant dynamism; shifting away from the cloud enables the use of edge
resources, with potential benefits in terms of privacy and costs. In this
scenario, collaborative applications must be decentralized; Local-First
Software operates and stores its data locally while still allowing for
collaboration, without dependence on the cloud.
Several specific solutions already exist for designing and programming
decentralized and local-first software, but the task remains difficult. Our
workshop aims to gather researchers and practitioners and their insights to
the theoretical and practical challenges of developing decentralized
applications in today’s computing ecosystems, fostering the research and
development of suitable solutions in this area.
# KEYNOTE SPEAKERS
* Mira Mezini, Technische Universität Darmstadt, Germany.
Topic: integrating key concepts of distributed and local-first software
into modern programming models.
* Pavle Subotic, Sonic Research, Serbia.
Topic: formal model guided conformance testing for blockchains.
* More keynote speakers TBA
# TALK PROPOSALS TOPICS AND SUBMISSION INSTRUCTIONS
We welcome the submission of talk proposals related to the theory and practice
of programming decentralized and local-first software. The talks can be about
new, already published, or in-progress work. We are particularly keen on
fostering the dialogue between industry and academia. The talk topics include
(but are not limited to):
* development methods and tools
* programming language design and implementation
* static and dynamic verification techniques
* consensus in decentralized environments
* decentralized data indexing, querying, and searching
* security, safety, and trust
* performance and scalability
* case studies, best practices, and experience reports
The talks will be scheduled for roughly 20 minutes + 10 minutes of questions
and discussion. Submitted talk proposals can be at most 2 pages long (using
any 1-column page formatting style of your choice), and they must outline:
* the title, content, and scope of the talk
* the context (speaker, company, research group, larger project, etc.)
* optionally, appendices or links with further information (e.g. existing
paper or draft, prior talks, project websites, etc.)
