| Abstract: |
Disk Paxos is an algorithm for building arbitrary fault-tolerant
distributed systems. The specification of Disk Paxos has been proved correct
informally and tested using the TLC model checker, but up to now, it has
never been fully formally verified. In this work we have formally verified
its correctness using the Isabelle theorem prover and the HOL logic system,
showing that Isabelle is a practical tool for verifying properties of TLA+
specifications.
