HowTo Setup vBFI

See: Main_Page

Background

vBFI provides the equivalent number of bitcoin confirmations that a VeriBlock block has.

How to set up

vBFI is contained within NodeCore. It is an optional plugin, not run by default (to conserve resources).

It is available with 0.4.13-rc8 and later (TODO - this is a pre-release)

1. Run a full nodecore instance: NodeCore_QuickStart
2. Open up port 4567 for bfi
3. Add file bfi.conf
4. In nodecore.properties, set bfi.enabled=true

If you run getdiagnosticinfo, you will see this flag enabled.

bfi.conf

bfi {
    blockChainNetwork = mainnet
    nodeCoreRpcHost = "127.0.0.1:10500"
    httpApiBindPort = 4567
    httpApiNotificationsTest = true
    forkThreatThreshold = 2
    forkThreatRatioThreshold = 0.8
}

nodecore.properties

# Enable BFI
bfi.enabled=true

Get results

bitcoinConfirmations for each transaction

This is available per transaction via the bitcoinConfirmations field:

gettransactions 2AB3811FD0EDE3B3F89A50926B15AA4C0C2370A4467E6670635A19E5A1CD3AF3 5000

...
"bitcoinConfirmations": 4,
...

There is also a JavaScript sample to call the http api for gettransactions:
