    A little update:

    Tomorrow I'm going to complete refactoring the code and writing the comments, after that I'll send back-end code to those who offered to do the review.
    Front-end won't be ready by Xmas, because we decided to rewrite it completely - first impression is very important (and also iotas won't be claimed till that date anyway).
    I stripped out code that decides which tangle tips to extend, during beta phase all nodes will work with help of a special "coordinator" node, this solves problem of someone cloning Iota right away. After the release coordination can be disabled (it's up to a node operator), we will still be running the coordinator, it's necessary to protect Iota until it gets enough hashing power.

    Very nice! Good job so far, IOTA will be BIG!

    5 reasons you’ll embrace digital transformation in 2016

    Quote
    To be truly transformed, companies must go beyond window dressing the customer experience, embedding a few sensors to monitor production, and monetizing a service with digital technology. They must reach deep into the bare bones of the company, going as far as human resources and finance and as high up as the executive boardroom.

    In case anyone has noticed my comments regarding a C# address generator, I've created the C# address creator which could be used for a vanity gen.  This was created by copying and modifying the JS & Java code with only minimal modifications.  On my machine, this creates ~20 (yes, 20) addresses a second, and I've even added a little parallel execution into the process.  It's all of the loops embedded within loops that CfB has created....

    I'm going to have to study what you guys are doing in order to optimize this.  Regardless, even a 100x improvement in address generation will mean that vanitygens won't be reliable for searching for more than 3-4 characters at the beginning of an address.

    Oh well, c'est la vie.

    It's great to have a vanitygen. Keep us updated.
    Do you have a git ?

    Yes, but I've not posted it to my git account.  I'll post it when it's cleaned up a bit coz my first-pass work is always cobbled together with spit and duct tape.  I like to just make stuff work, first, and polish later. Tongue

    I do have a couple of vanitygens there:

    SaM hashing is done @ approximately 30 kH/s rate on an average CPU (Java version). Address generation requires at least 27*27+9=738 hashes. This gives 30000/738=40 addresses per second.

    Is it possible to send IOTA without internet connection? Of course, I also think it is very likely impossible. It's said that bitcoin can be transferred with radio wave. So if IOTA can be sent via it, IOTA can be used in many application cases.

    Sorry for my ignorance but is "SaM" hashing the full process of taking a clear text string (the users passphrase) and converting it to an address hash?

    Because in your code, you have operations such as 9 hashing rounds x (729 iterations for some left/right calculations + another 729 iterations for left/right index assignments and look ups.)  So, that operation alone is 13,122 operations within your transform method... which gets called multiple times per address.

    Again, I need to dig into this and figure out the point of each step in your code, but with the exception of initializing the INDICES table just once, I have to execute all of your code for each address.

    I hate to ask for a cheat, but are there other ways that some of this could be cached or simplified for barebones address creation?

    Thanks for keeping us updated in the thread as we go along. Can these updates be condensed somewhere (twitter, this thread's op, the website) so that people not actively following the thread can have the info?

    SaM is just a hash function - https://github.com/JinnLabs/SaM/blob/master/src/SaM.java. A single hash requires 19683 lookups to F.

    Good idea, i think CfB is full of work right now , but for sure  it will post an updated time schedule these days.

    to remember that we are also at Christmas time, probably he has some time to spend with his family too..

    I have started an Italian language topic about IOTA. I hope the Italian Comunity will help this project.
