#Protocols
Byzcoin
XXX Need references. ByzCoin implements the ByzCoin protocols which consists of two CoSi Protocols:
- One Prepare phase where the block is dispatched and signed amongst the tree.
- One Commit phase where the previous signature is seen by all the participants and they make a final one out of it. This implicitly implements a Byzantine Fault Tolerant protocol.
PBFT
PBFT is the Practical Fault Tolerant algorithm described in http://pmg.csail.mit.edu/papers/osdi99.pdf . It's a very simple implementation just to compare the performance relative to ByzCoin.
Ntree
Ntree is like ByzCoin but with independant signatures. There is no Collective Signature (CoSi) done. It has been made to compare the perform relative to ByzCoin.

Overview ¶
The storage point of all protocols that Cothority can run.
If you want to add a new protocol, chose one of example/channels or example/handlers and copy it to a new directory under protocols. Adjust all names and implement your protocol. You can always test it using the _test.go test.
For simulating your protocol, insert the include-path below, so that the Cothority-framework knows about it. Now you can copy one of simul/runfiles/test_channels.toml, adjust the Simulation-name and change the parameters to your liking. You can run it like any other simulation now:
cd simul go build ./simul runfiles/test_yourprotocol.toml matplotlib/plot.py test_data/test_yourprotocol.csv
Don't forget to tell us on the cothority-mailing list about your new protocol!
