Cardano-node 1.14.1 error with genesis file

Trying to build from the latest tag and it built successfully but I keep getting this error when running. Anyone know what this error is and how to resolve? I find it weird that when using that tag the version still prints as 1.14.0.

There was an error parsing the genesis file: /home/cardano/node/config/ff-ge│
nesis.json Error: “Error in $.genDelegs[‘68c3462163394860dbea2153d9969c7493c│
3aedcafa951cce80d54f009179c6e’]: Hash is the wrong length”

ff network configuration is being used

You need to use shelley-testnet network. FF is old network

Gotcha, thanks

Had the same issue, however when I follow the docs ( )

is automatically using the ff network, how do I use the new network ?

The OP has the correct link to genesis, topology and config for different networks.

Hey @rdlrt thanks for your response.

So basically just to clarify do I have to recompile with the new configuration?

The original command that used the ff-network was based on the commands here:

git clone
cd cardano-node
nix-build -A scripts.ff.node -o ff-node-local

Not sure what scripts.fnode -o ff-node-local does as I didn’t use nix before.

Where are these file located and how can I replace them ?

Can you clarify more indicative how I use those files?

Thanks in advance

I’ve tried to find the release 1.14 on gitHub but the latest is still 1.13,
the 1.14 branch looks old,
do I have to download the master branch?


You need to use release/1.14.x branch for compatible binaries and network. Please check out the pinned message on workgroup for some common gotchas people are falling into.

I did not paste it here as things change at rapid pace, and there might be differences from date of post to next :slight_smile:

Thanks a lot,
after adding the new package dependency libsodium-devel,
I’m compiling.

while i’m building on centOs8 system,
i’ve the following error:

I’ve tried on fedora 31
but is the same.

Can you tell me something.

The mention message linked above contains ways to resolve this exact error. The new cardano-node readme file is also updated to resolve this error.

Ok thank you,
after adding

package cardano-crypto-praos
flags: -external-libsodium-vrf

in cabal.project

I’ve solved the error and bilt the 1.14.1 version.

i just followed the same nix instructions and have the same problem.
i dont understand the answer below.
Did you have to recompile the node? or just change some files?
I like how they say that the nix methos"…is the package manager of choice for IOHK’s internal development teams, and thus the recommended method for building a Cardano node to run on your machine."
and then it installs the ff version ? why?
