Attention delegates: Make sure your pass is strong. A trusted delegate was hacked last night and lost his testnet lisk(stealing fake coins  yay!) He did not have a secure pass. Seems the coins were transferred to an account named pangu.

NOW I AM. HAH!

hocus pocus... punk.

I am the 12.000th reply

Hey how did you do that???

Code:

//Lines 260-265
private.openAccount = function (secret, cb) {
	var hash = crypto.createHash('sha256').update(secret, 'utf8').digest();
	var keypair = ed.MakeKeypair(hash);

	self.setAccountAndGet({publicKey: keypair.publicKey.toString('hex')}, cb);
}


//Lines 268-280
Accounts.prototype.generateAddressByPublicKey = function (publicKey) {
	var publicKeyHash = crypto.createHash('sha256').update(publicKey, 'hex').digest();
	var temp = new Buffer(8);
	for (var i = 0; i < 8; i++) {
		temp[i] = publicKeyHash[7 - i];
	}

	var address = bignum.fromBuffer(temp).toString() + 'L';
	if (!address) {
		throw Error("wrong publicKey " + publicKey);
	}
	return address;
}

EDIT:

Please let me know if I'm understanding this correctly.  To get a Lisk address, all I do is take the SHA-256 hash of the secret key, derive the Ed25519 pub/priv-key pair and then convert the first 7 bytes of the pub-key to a long?  What is the "cb" parameter?  I see it passed around everywhere and I also see that some method is named that.  I can't readily find it's definition.

Hey guys let's keep it on topic. We may have a huge amount of posts, but a huge part of that is complete bs
So yeah, let's just keep this straight discussion about Lisk, and let's try our best to read up before asking again

[wasref]

How funny LISK don't even have DAPPS javascript is not compatiable and this aint even FUD amazing the only real fud they have against ethereum is that solidity language they're using is not popular

there is a reason why vitalik didnt use JS for the back end because it wont work for their plan lisk can be coded to play games like hangman, free candy crusher or flipper remember FUN APPS not fun dapps

if you ask me they hyped up the coin for something they dont have

$5.9million for 1 year work nice wage maan

This can't happen on the mainnet, because we are enforcing BIP39 passphrases in the UI.

Code:

//Lines 260-265
private.openAccount = function (secret, cb) {
	var hash = crypto.createHash('sha256').update(secret, 'utf8').digest();
	var keypair = ed.MakeKeypair(hash);

	self.setAccountAndGet({publicKey: keypair.publicKey.toString('hex')}, cb);
}


//Lines 268-280
Accounts.prototype.generateAddressByPublicKey = function (publicKey) {
	var publicKeyHash = crypto.createHash('sha256').update(publicKey, 'hex').digest();
	var temp = new Buffer(8);
	for (var i = 0; i < 8; i++) {
		temp[i] = publicKeyHash[7 - i];
	}

	var address = bignum.fromBuffer(temp).toString() + 'L';
	if (!address) {
		throw Error("wrong publicKey " + publicKey);
	}
	return address;
}

Almost! The public key is hashed again using SHA-256 and then the first 8 bytes of the hash are reversed. The account ID is then the decimal representation of those 8 bytes.

I'm semi concerned about that too. But, I'm much more interested in seeing the project attempt to work through all of this and develop something meaningful. Further, I'm also really interested in seeing a roadmap and team update/tech update on the plans for the millions of dollars - what devs are being hired? What's the plan? Where is this going in the vision of the team in place currently.

Right now there is not much brain power focused towards LISK - reading through this thread shows that 99% of the people here just want absurdly crazy ROI at any cost. Very little talk is about development or use cases almost all of it is just plain "moon for moon's sake".

Curious to see what substance the team can put together for 5 million bucks.

if you ask me rtcrypto how did they raise all that. i wasnt here from the start so dont really want to go back 600 pages but did they have some marketing campaign going on how did they hype all this to raise so much. well as a trader i'm not happy i never bought as a investor/developer happy i didn't. i couldn't buy this at ICO price if i had the chance without seeing what they have planned and seeing through their double meanings

lol..there's no way a coin written in javascript will survive the strommin'.. yubikeys haxxors lol ..proofs? 

[SilverCondor]

May LISK's price fall after ICO coins distribution and probably price dumping by ICO participants?

We dont know what LISK price is currently, we know only LISK-IOU price. You probably meant that second price. Sure it is very possible that LISK price (if started from LISK-IOU level) may fall after launch.

Ok, thanks.  I have my code working.

Please explain what "BIP39" means?  If I generate my own accounts from random character strings, will this cause any issue?  What are the limitations enforced by BIP39?

This enforces extremely secure passphrases.

perhaps once the mainnet launches this thread should be closed with the last post being from LiskHQ with a link to lisk.chat

Ofcourse not, this is a great place for discussion and getting attention to Lisk.

They raised it because interest was very high for the project and because Ethereum was going through a massive pump (which I think is legitimate, I'm very bullish on Ether)... this led many people to hope that they could find the next moon rocket of x10+ returns. Timing really helped the LISK fundraising. Soon it will be time to put the funds to use and develop something truly meaningful, I'm excited to see what the team will do with the funds and what projects come out of this. The community is maybe a bit immature and mostly made up of moon kids, but, the team is serious in their desire to build something worthy of all this money raised.

Certainly not.
Lisk needs a broadly positioned community.
And along with many other possibilities, Bitcointalk is a great platform and many users are very familiar with it.

yeah, but there are far too many fudders on here who use spurious technical discussions to damage the rep of Lisk. i suggest they be funnelled to lisk.chat to be educated.
