Order shared events
Two people can change the same record at once. Define which changes need a shared order and how conflicts should resolve.
Consensus and protocols
Shared rules.
Clear agreement.
SafeDev builds custom consensus and protocol solutions for private products. We help founders and CTOs make shared data behave as intended, even when machines disagree.
Discuss Your ProjectConceptual view, not a deployment map
Make agreement part of the design.
Consensus means reaching agreement across machines. A protocol sets the rules they follow. Both start with what your product must protect.
Set trust boundaries
Decide who can join, send changes and read data. Agreement alone does not make data private or grant access rights.
Plan for failure
Messages can arrive late, twice or out of order. Set clear rules for retries and recovery before those cases reach users.
Where PARSEC fits.
PARSEC is an approach to distributed consensus: agreement without one central decision-maker. SafeDev brings depth in PARSEC alongside its Safe Network focus.
We assess the fit against your data flows and failure risks. Custom protocol work should solve a clear need in your product.
