Much like IOTA.

What's the exact name for this chainless protocol, dag?

I've got an interesting link:

http://www.meetup.com/bitcoin-il/events/227289840/

Casper is claimed to be very lightweight, if it's true then Iota and Ethereum may compete for the same place under the sun. Taking into account that Ethereum is working on specialized hardware too we can say that Ethereum has what Iota does + Turing-complete language for smart-contracts. I left a possibility to add smart-contracts into Iota in case if Iota and Ethereum communities pick competition over cooperation. Interesting times ahead...

No, there is a much more serious problem - PoW blockchains can be mined much faster by QCs, but Ethereum is switching to PoS, so this problem will be solved automatically. If PoS blockchains are secure in postquantum age is a question that wasn't analyzed closely though.

ok, here it is:

Lamport scheme is very similar to Winternitz one.

90 days from end of sale... sooner the better though *launch wise*

till when to claim our IOTA?

SENT

 

I have just sent my BTC pilot TX- it should be all right, but can I verify its correctness somewhere?

Post you address.

 
[solved]
I am not sure I understand this step :

type the address that you just generated into the form below. Hit 'Send' to get the amount of satoshis to transfer in order to verify your ownership.

Can someone rephrase this ?

I never got "the amount of satoshis to transfer in order to verify my ownership", is it a bug ? I only get a blank page.
I guess the server is saturated of request... I'll try later.


EDIT : I forgot to remove the space before the last 2 letters so the site didn't recognize my address. Thanks Come-from-Beyond.

Very interesting and new concept Come-from-beyond. Thanks for keeping us in the loop here.

Merry Christmas IOTA-Team!

I got some questions about the code, I'll post replies here so other reviewers will see them too.

There are transactions in Iota and their bundles. A bundle = one or several transactions. Every transaction can be a message, an output or an input. A message doesn't change balances and can contain any data. An output is an operation that increases the balance of an address. An input is an operation that decreases the balance of an address.

A typical transaction bundle may look like this:

-500 XXX
+400 YYY
+100 ZZZ
0 For Neuropozyne (50mg)

Here we see that XXX sends 400 iotas to YYY and 100 iotas (change) back to himself. There are 4 transactions, -500 is input and +400 and +100 are outputs. So transactions with negative values are possible. 0-value transactions can be ignored when calculating balances.

SaM hashing function is my invention. I used the same principle as was used in Keccak aka SHA-3 and followed all advices that I found in papers analyzing security of other hash functions. It doesn't guarantee that SaM is cryptographically secure, it's impossible to prove that a particular hashing function is secure (unless it's a balanced bent function which doesn't actually exist), only time can increase assurance that SaM is secure. There is no another trinary function which suits our needs, so not much choice here.

If we assume that SaM is cryptographically secure then the rest is secure (to some degree defined by the signer), because Iota uses Winternitz one-time signature scheme which is well-studied.

---

We already contacted cryptographers asking them to review SaM but this process is long, also they, of course, are busy with their own stuff.

There has arised a little misunderstanding regarding the reviewed code. To make it clear:

1. It's a back-end, some things like transaction signing will be done in front-end, this is why this code absents
2. It's a reference implementation, some things are not efficient because readability had the highest priority
3. Iota is lightweight literally, it's not a marketing trick. A single transaction format, a single packet format, a single workflow for data sharing - all these things led to little code.

PM or Ryver if you need realtime.

Sorry, I'll try to quite down in a bit but regarding code review, should we post our questions here, or via PM?  I already see something that I'd like to explain, but if you'd prefer for review questions to be asked in a private/semi-private manner, let me know.

To those who don't find their address in http://188.138.57.93/old.txt - reenter it again via collect.iotatoken.com, please. No need to resend the payment.

When you are successful enough that some 4chan child takes notice, you have come a long way.

A script kiddy is playing with our server right now. Hold on.
