I'm currently working on a semi-automated characterisation of coin features.

Cool list. I think it could be perfect, if we had a topic to compare features and how they are used in alt-coins

Something like this?: https://bitcointalk.org/index.php?topic=675821.msg13484427#msg13484427

(and the three following posts)

Here's the current feature set, including the anon features, rendered in N3. The next step is to hack up some code to inspect and report on repository content and ultimately derive a feature set from the data, mostly satisfying BitcoinNational's requirement.

Code:

DOACC is an altcoin catalogue expressed in RDF and the features described above can be combined with the DOACC altcoin metadata and is amenable to SPARQL querying so people can generate their own permutations of lists.

For each altcoin, DOACC attempts to record:

name - the name of the coin
ticker - the stock ticker
protocol - the network protocol
protectionscheme - how the chain is protected
incept - YYYY-MM of announcement
date_founded - the date that the coin was announced
block_time - the block time in seconds
powscheme - the hashing scheme
block_reward - the block reward
reward_modifier - the reward halving/modification scheme
premine - the amount of any premine
total_coins - the total number of coins
retarget_time - the block target time
website - the coins web site
source - the location of the source code
posscheme - the type of PoS scheme used
confirmations - the number of confirmations recommended
maturation - the maturation time of newly-minted blocks
distributionscheme - the scheme by which the coin was distributed

But the older data is often much more sparse.

I have an experimental version of the graph that cross-references each coinmarketcap.com-listed coin with the corresponding marketcap, volume, price etc in the coinmarketcap.com listings so I can also use those values as filters.

Cheers

Graham
