i started an index of filesystems, awhile back. afs, bfs, cfs, dfs, etc..
while looking for other peer-to-peer backup/storage systems, today, i ran into this. there’s a reference to bfs in there. it is described as:
This project is aimed at developing algorithms and implementation techniques to build practical Byzantine-fault-tolerant systems, that is, systems that work correctly even when some components are faulty and exhibit arbitrary behavior. We believe that these systems will be increasingly important in the future because malicious attacks and software errors are increasingly common and can cause faulty nodes to exhibit arbitrary behavior.
