nice work, i will have to check this out !!

would urge you if you get time to do a git pull to add support to official abe on github

https://github.com/bitcoin-abe/bitcoin-abe

jtobey regularly adds different algorithms....

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 ...

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:
