Is there any article, website or anything else where the properties of Nxt are compared to Peercoin? I could do this myself, but maybe somebody has already elaborated.
If not, maybe we could do a comparison here in the forum. Let’s begin with the statements that are mentioned in the article that can be found on Wikipedia about Nxt.
###Source code
- Nxt is written in Java and is a completely separate implementation of a blockchain based network. First one to be fully independent of Bitcoin as well. It’s very different technology. The first block was generated on 24 November 2013 (source), the full source code was released on 1 March 2014 (source)
- Peercoin is written in C++ and based on the source code of Bitcoin. The source was available from the beginning.
###Premining
-
Nxt was the first ICO. The whole sum of all ever available 1,000,000,000 coins were premined, distributed to 73 stakeholders (source, source that explains why the founder decided to do so)
-
Peercoin’s founder and main developer Sunny King announced the planned release of Peercoin 9 days before the release. There were no blocks mined prior to launch. One forum member wrote:
> [Sunny King] released a link to the source in the other thread at the promised time (5 min before 18:00 UTC). There was no premine. By the time I had built from source and got things running, there were 5 blocks mined. ([source 1](https://bitcointalk.org/index.php?topic=99735.0), [source 2](https://bitcointalk.org/index.php?topic=101820.0), [source 3](https://bitcointalk.org/index.php?topic=101820.msg1114141#msg1114141) and also very interesting [Sunny King's response to accusations from flibbr](https://bitcointalk.org/index.php?topic=101820.msg1847081#msg1847081))
###Multisignature transactions
That is: Me and you can co-own an address and no funds can’t be spent without our mutual consent.
- Nxt has introduced multisignature capabilities on June 2015 source
- Peercoin has multisignature capabilities since inception (e.g. it was used for the crowdfunding of Indicium), and it was part of the (now abondoned, but still usable) Peerunity wallet software, and will soon be available again in the graphical user interface of the current main wallet software (merging it into the core client was deemed lower priority) (source)
###Multisignature for minting (allowing cold minting)
That is: Your minting wallet can stay online without any coins in it, the other wallet with all your wealth is offline (=cold). They are connected via multisignature.
- Nxt doesn’t have it.
- For Peercoin it’s on the roadmap, planned for Q4 2018 (post v0.7 development cycle) (source)
###Security and (im-)possible attacks
- Nxt has a reorganisation resistance at 720 blocks, which closes some attacks and opens up others (???).
- In Peercoin there is no reorganisation resistance but up to date only centralised checkpointing to prevent reorganisation. However the following seem to be only myths:
###Block creation rate
- The Nxt network takes roughly 1 minute to create a new block. (source)
- In the Peercoin network the approximate time between two blocks is 10 minutes (no source yet, but I know it because it is similar to Bitcoin’s behaviour)
###Rich list aka wealth distribution
-
All the 1,000,000,000 coins of Nxt were initially distributed to 73 stakeholders (as mentioned above in the Premining section), that means 13,7 million coins per stakeholder (if equally distributed, which wasn’t the case). Today (2017-12-08) the distribution of the top 10 stakeholders looks like this (if I understand the statistics on this page right, which seems to show the minting stakeholders, called forgers in Nxt-language):
1 50,003,812 5.00 % 2 44,170,316 4.41 % 3 30,175,127 3.02 % 4 10,079,928 1.01 % 5 9,196,765 0.92 % 6 4,071,348 0.41 % 7 5,553,867 0.56 % 8 2,502,153 0.25 % 9 507,881 0.05 % 10 151,282 0.02 % -
Peercoin has the following list of richest top 10 stakeholders (as of 2017-12-08, copied from this source):
1 2,130,836.52 8.70 % 2 1,894,142.18 7.73 % 3 1,026,580.99 4.19 % 4 907,607.88 3.70 % 5 865,785.98 3.53 % 6 553,009.76 2.26 % 7 303,404.16 1.24 % 8 213,154.59 0.87 % 9 201,092.59 0.82 % 10 200,417.75 0.82 %Nagalim commented on the distribution:
it is extremely easy to hide one’s wealth by sending it to different addresses […] Peercoin actually motivates against moving coins a lot, so it is unsurprising that Peercoin’s richlist looks different than other coins
###Extra features
- Nxt has (as of source 1 and source 2):
- Data storage
- Assets
- Vote system
- Marketplace (what???)
- Alias
- Peercoin has (as of source):
- Coin control (what???)
###Smart contracts
- Nxt uses core transaction types that can be used to do a subset of smart-contract-like actions on the chain.
- Peercoin: There are plans to expand on bitcoin’s script system, but not enough to call it smart.
###Fee structure
- Nxt recirculates the paid fees (how much?) as a block reward for min t ing. Similar to Bitcoin, but they pay for mining.
- Peercoin burns their fees (minimum is 0.01 PPC per transaction and per kB of transaction storage size, see this explanation on the fee structure of Peercoin). New coins are created independently by min t ing and mining. See this lengthy but detailed discussion about Peercoin’s fee structure and the fee burning.
I found a small and almost unreadable infographics from January 2014 created by a Nxt supporter in this discussion.
