Well, I only know about Ripple and Bitcoin in more detail...
From top to bottom:
Bitcoin: "Worst case time" is 100 blocks, not 120 (I guess you mean coinbase transactions) - the core client used (maybe still uses?) an additional stop on transaction for 20 more blocks but you can validly spend coinbase transaction outputs after 100 block already.
Unfortunately there are no good public numbers for Ripple transactions per second (well, you can of course parse the numbers yourself), I would guess the current load is about 1 TPS, other numbers seem to be maximum numbers(?). The maximum number for Bitcoin is by the way ~10 TPS (
https://en.bitcoin.it/wiki/Maximum_transaction_rate) and since P2SH is getting more popular, 7 TPS is already not longer an average number any more.
"Anonymous Transactions" - what exactly constitutes this? E.g. you could launder/mix BTC but you'll still see publicly the inputs and outputs.
Bitcoin transactions have variable fees, they are not fixed. Maybe you should write "average" or "minimal" TX fees?
Ripple is not totally free network security wise, you'll at least have to host a server relatively securely. Maybe "no further costs apart from hosting a server"?
Using advanced output scripts, a few of your use cases might be possible with BTC too (e.g. "dividends", depending on what you mean with that) Mastercoin and Counterparty are better designed for that use case though I guess.
"Market Pegged Assets" - More explanation needed
Bitcoin inflation is NOT 10% (well, currently it might be...), it is algorithmic and pre-determined.
User Issued Assets - Depending on your definition of "assets", IOUs on Ripple would also fall into this category
User Registered Accounts - (?)
Encrypted Messaging - Ripple supports a "memo" field, that could be used for this (and other stuff) but it is not exposed in the official client.
Monetary system - (?!)
Alias: DDNS - (?)
Asset Exchange - Again, depending on definitions, Ripple would fit this quite well.
Decentralization - REALLY needs more background and a clear definition what needs to be fulfilled to be considered "decentralized" (e.g. all of these systems are based on central databases that need to be globally consistent)
Marketplace - Difference to "Asset Exchange"?
Transparent Forging - (?)
Cross chain trading support - There are schemes published for Bitcoin already for years. They are not implemented in the reference client though.
Smart leasing - (something like lending on Bitfinex?)
Multisig - In the works for Ripple (
https://ripplelabs.atlassian.net/browse/RIPD-182)
Account Control - (?)
Automated Transactions - Please define this further - e.g. a certain transaction can be initiated without anyone signing a transaction (either offline or online), similar to margin calls.
DAC - Buzzword, no definition
Smart Contracts - Ripple Labs is developing
https://github.com/codius/codius/, it is running independent from Ripple though, so it could also enforce Bitcoin transactions.
Blockchain Pruning - Ripple's ledger is fully pruned, you can get up and running within minutes at most. History is much larger than on other platforms though. Bitcoin also of course can be pruned and there are patches to do this already available.
All in all - Thanks for this work, it is quite well done. It would really help to have a bit more general and better defined "features" instead of mostly NXT marketing speak that most others of course won't be 100% able to fit into. Also please seperate the native asset/currency from the platform itself. NXT-coins do not have an Asset Exchange, NXT-platform does for example.
I will point the people who worked on the chart to look into it and where needed update-correct is.
As to the "marketing-speak", we need to try to minimise that in this chart to a the minimum. In fact, I commissioned it, and one of the points I stressed was that it should not be biased towards Nxt.
It being posted on a Nxt thread makes that difficult enough in itself, of course.
There just wasn't anything like this, at least to my knowledge.
Please keep sending comments (praise can go to for Fatih87SK and Salsacz who made these two and did all the research for them).
I myself would really have all this in one place for a change instead of having to hunt all over the place.
