Implementation Notes

Test Notes

1. Install Go 1.13.
2. go get -u github.com/yahoo/bftkv
3. Install GnuPG 2.x
4. Install Docker (if you want to run BFTKV in a Docker container)
5. Run setup.sh in scripts (setup.sh -host bftkv for Docker)
6. If bftkv runs with KeyTransparency, run $GOPATH/src/github.com/google/keytranspreancy/scripts/gen_bftkv_keys.sh

# change to the directory where the source code is checked out
cd bftkv
go install -v github.com/yahoo/bftkv/cmd/bftkv

A list of parameters that can be supplied to bftkv is given below:

Flag     Purpose                               Default
-home    Path to PGP home directory,           ~/.gnupg
-sec     Secret key ring path,                 $home/secring.gpg
-pub     Public key ring path,                 $home/pubring.gpg
-rev     Revocation list path,                 $home/revocation.gpg
-db      Database path,                        db
-api     Http api address,                     localhost:5792
-ws      Web socket port,                      5001

1. Run a node bftkv -home gnupg.key

2. Run a BFTKV cluster cd scripts/run; ../run.sh

3. Run a BFTKV cluster in Docker

docker build -t bftkv .
docker run -d bftkv

BFTKV includes a visualization tool (located in visual/) for observing the current system state. The tool can display

• Trust graphs for the servers
• Read, write and sign requests sent to the servers
• Revoked and inaccessible servers

To show the graph, run run.sh and open visual/index.html.
