I'm interested to know why you have removed the total btc investment figure from your IPO webpage?

You need to be logged in.

NxtChg, I suggest you stop the ipo at 100 investors. We are at 98 right now and tomorrow is April 20. You will have kept your word and 100

investors sounds soooooooooo good.

When the IPO is closed for new investors. Can the investors that already have invested, invest some more BTC? Thanks.

Too late: 103 with 63 BTC.

Guess, we have to wait for the next round number. What is it, a thousand? Wink

Of course not.

Long posts without pictures are boring, so I think this is an appropriate one:



Ok, today is the last 100% safe day when the IPO won't be closed, so I thought I'd post a progress update for the last 12 days since the announcement.

You saw the address generator and lookup tool that I've posted here. Did some tests and settled on how account ID's will be generated.

The 3 main cryptoprimitives, which should be enough to build the system, were ready before the announcement. I found a bug in my Blake2s implementation when I did the address generator, so I wrote a unit test for it to compare to the reference implementation, and plan to do the same for Salsa and Ed25519, as well as other code.

Did some experiments with key stretching algorithms.

Converted Reed-Solomon addresses from NXT to the new format. Updated test addresses generator. Did extensive testing with 1 million corrupted test addresses.

Wrote a wrapper classes for SQLite, which will be used as our main database. The database interface code is now 90% done.

Did a lot of timing tests, both for crypto and database performance to assist me in making design decisions. Figured out protection from data corruption for the database. Wrote the code to do ledger verification on loading. Created a test ledger with 100,000 test accounts (about 10 Mb at this point). Verification takes less than 1 second, but that's without transaction history.

You've seen wiki, that took some time. I also keep documenting things in my local copy to be published later.

Console server skeleton is mostly finished, ini and log files, graceful shutdown, that kind of stuff. Ready to be filled with meat.

A lot of thinking went into trying to figure out the best encryption scheme for packets and at the same time protect from application-level DDoS attacks. I think I finally settled on how it will work.

Implemented transparent encryption/decryption in network code. Tested UDP connection between my home PC and the simcoin.info server – it worked perfectly. Also made sure that VPN indeed hides IP's for our UDP packets.

Also, beware of phishers!

Somebody at nxtstore.com is trying to do something with the IPO site.

Maybe he's legit, but why would anybody with that address want to do anything with Simcoin using paths like this:

/wolftest/sim.php ?

Anyone knows what this is? I can't access that domain for some reason.

Put your email in the profile at the IPO site, so even if your account is compromised you can always claim it back.

The IPO will be closed when the btc reaches 69.5 or more.
Now the dev is staring the number and preparing his victor picture.

We all know that. Wink Wink Wink

Good to have some real news.

Will simcoin launch in one month or do you think it will take longer?

Thanks.

Hi,NxtChg.com

I just notice this
https://bitcointalk.org/index.php?topic=561294.200

The nxtstore.com belongs to my team, we are testing the Nxt mall,and it got hacked 。

The hacker did all as you described,and we have deleted the false information now .

My team member is restoring the database now and we have shut down nxtstore temporarily.

www.nxtstore.com is not a IPO website,is a Nxt accepted mall.

Sorry to disturb or effect your site simcoin.info.

Sorry again for our carelessness,and we will reinforce our website safety.

What's so special about 69.5? Why not 100? Smiley

In one month only the Test Net might be launched. Official Simcoin launch will be much later. It's hard to predict.


Investor list keeps getting bigger and bigger.  Cool

Time to call my yacht designer and ask for a helipad Cool

I understand. I don't mean all the features and fully launched. I mean, do you think it will take more than 2 months until an alpha version is launched and people can actually see something and start trading their coins, etc?

As for the yacht, tell him to make one for me too. Smiley

It's really hard to predict. It's my first coin, you know Smiley

On the one hand, when it comes to developing software, things usually take longer than it looks.

On the other hand, focusing on simplicity reduces the amount of code to write and decreases debugging time. But unexpected issues can always pop up and delay things.

The core of the system is not very complicated, so Test Net in a month is realistic. What is complicated is all the other stuff - good clients, merchant integration, etc.

About trading - I haven't decided yet when to setup the exchange. That can be done in a day or two, the question is when? Should this be done before people can access their wallets in the system? I don't know.

You need to bring another 100 investors first Wink
