difficulty still up and down but never dropping too low,

At one point, I hacked up a Python sifcoin-hash module (https://github.com/gjhiggins/sifcoin-hash) to get a Sifcoin version of Abe up and running:

Code:

datadir = [
   {
   "dirname": "/home/gjh/.sifcoin",
   "chain": "SiFcoin",
   "policy": "SiFChain",
   "code3": "SIC",
   "address_version": "\u0010",
   "script_addr_vers": "\u0005",
   "magic": "\u00f2\u00d5\u00d3\u00d8",
   "loader": "blkfile", # See the comments for default-loader below.
   "conf": "sifcoin.conf"
   }
]

The Abe.Chain.SiFChain subclass is quite straightforward ...

Code:

from . import BaseChain

class SiFChain(BaseChain):
   """
   A blockchain that hashes block headers using the SiF algorithm.
   The current implementation requires the sifcoin_hash module.
   """

   def block_header_hash(chain, header):
   import sifcoin_hash
   return sifcoin_hash.getPoWHash(header)

(I continue to run a SiFcoin node but I've migrated away from Abe in favour of ACME, my own (as yet unfinished) lightweight RPC-based blockchain explorer implemented in Python: https://minkiz.co/acme/sic --- it's basic and atm, barely better than the raw JSON but I have plans for it).

Also, fwiw: on a whim, I transcribed the Sifcoin code back into the full commit history, added getnetworkhashps to the API and squeezed a diffplot chart on to the overview page:
