You're being childish. Why don't you just explain the beauty of your concept instead of getting all fiery wild about how I understood your statement about receiving REC. That's how I understood it. All you have to do is explain it so no one else will misinterpret it the way I did.

You have all the information you need on the website, whitepaper and code. If you post any specific technical question, and it seems serious to us, you'll be answered.
Well it is not up to you to decide if we have all the information we need. That is up to your target audience.

But, let's go into a technical discussion, if that is what you want. I take this passage from your "whitepaper", which I would not really call a whitepaper, because it leaves out most of the details, and fails to connect the dots of information that are in it.

Quote
Addresses

Every account address is represented with 32 digits, and is created the following way:

1. A random private key is chosen
2. A point on the curve is calculated into a 64 byte array
3. The byte array is collapsed into a 16 byte array
4. A constant 16 byte array called “Network Bytes” is also added
5. If all bytes in the address are below 100, the address is valid and can be represented with digits only (32 digits for 16 bytes)

It takes some time to generate the address, yet it saves space on the chain and adds proof of work. While generating the address, the client may hit or recover one of the targets.
ad 1. What does the randomly generated private key look like? What are it's specifications?
ad 1. What does random mean in this case? What type/class of random generator are you using? Is it seeded, and if so: how?
ad 2. "A point on the curve is calculated into a 64 byte array". Many questions:
ad 2. What curve? what does a "point on the curve" mean? What point? what curve? What do you mean by "chosen" ? How does that work? Are there criteria to "choose" a point ?
ad 2. If you have 64 bytes, you have 64 bytes. An array is a representation of those bytes. What does that mean? How many elements are in your array? Is it associative or zero base indexed? How many bytes are used for the indices and how many bytes are for the data? The fact that the 64 bytes are an array implies that they are ordered. Why the ordering and how is the ordering preserved? Why the array representation? Sounds like bullshit to me.
ad 3. What do you mean by "collapsing a 64 byte array into a 16 byte array" ? Do you realise that if you reduce 64 bytes to 16 bytes, you are reducing entropy, thereby throwing away information? Lowering entropy is rarely a good idea in cryptographic systems. Please explain why this is a good idea in this case. Oh, and explain the "collapsing" algorithm.
ad 4. Why use 16 bytes for a constant? A constant is a constant. You are not using the 16 bytes entropy. Again: why is this a good idea? It does not add entropy nor information.
ad 4. What is the "Network Bytes" constant being used for? What is the purpose?
ad 5. Again lowering the entropy, by not using all bytes below '100' (assuming 100 in 10-base). Looks like you are throwing away all the advantages of high entropy in cryptographic systems, thereby making your system weaker with every step.

Please answer those questions, because they are a big big concern.



Thank you for your interest in the internals of our technology. Right now, we are talking about generating an address:

1. Private keys are 32 byte, randomly generated by a secure random class, same as bitcoin.
2. The ECDSA curve used here is sepc256k1.
3. The 64 byte point is the curve's generator multiplied n times (where n=private key). Then you have 32 bytes for the X coordinate and 32 for the Y.
4. These 64 bytes are split into 4 chunks of 16 bytes, where each position is added up modulo 256, resulting in 16 bytes.
5. Network bytes are used to identify the network (testnet/mainnet/other) and to validate the address (instead of checksum). The network bytes are also added up modulo 256.
6. If all 16 bytes are below 100, then it's a valid address. This does not reduce entropy of the private key generator, it's not even related to that. If you check it, it makes it difficult to generate the address therefore making it difficult to brute-force attack it.

Hope that helps.

7. The private keys are just used to demonstrate the PoW address


Private keys shouldn't just be given away casually. Asking for private keys raises red flags so thank heavens for people on the forum that can discern when something appears scammy.

There are people on this forum who - out of their good heart  Grin - make it their purpose to expose scams/scammers, so while they do their investigation and point out some questionable portions of the announcement, it would be best to show proof that the one being accused isn't a fraud  Wink

Who asked for anyone's private keys? Do you people know how to read or you are just trolling around threads?

youre write
in launch coin and create coin is expected in September 2017.
but this now month january youre open ico selling, collect bitcoin investor and without escrow because coin still not ready

All smartass traders, including you are welcome to get off this thread at once.

You have another thing coming bitalchemists Grin or should I say Triswardhani, loljosh, mintodev, templar77, Carlos RT Ferguson, nite69, Thewolfofcrypto Wink

You ain't fooling anyone Cheesy

Unless you have proof to what you're saying, you should hurry up and get the hell out of this thread.

BE CAREFUL PEOPLE, THERE ARE A LOT OF RED FLAGS HERE:

  • Anon dev
  • No Escrow
Promises things that are to good to be true: it walks and talks like a duck.
  • Github user is new and anon as well
  • Source code on Github is just C# and lacks a LOT
  • Source code on Github is C#, but OP mentions OSX and Linux as targets as well
  • This is dead wrong:
    Quote
    Deposit any amount in BTC to 19vVPuzXPBUiNdnr6KZwYP9rAtdtWkDjqi until 2017/03/01
    Get x150 to your parallel REC address
    (using the same private key of the BTC address you've sent from; funds will be hardcoded into the genesis block).
    Launch is expected in September 2017.
    Private keys are private keys. They should never be available for anyone but you. The person who has your private keys, controls your Bitcoin. So if the dev states that he uses your private keys to create REC coins in a "parallel" address, that alone should be enough to abandon this coin/project.

Keep your private keys safe. Make sure nobody gets your private keys. If someone is after your private keys, he is after your bitcoin!


1. Satoshi nakamoto was anon dev
2. You can have anon escrow and still be legit
3. This is not the best proverb you could come up with
4. Everything has a starting point
5. What exactly is the code lacking in your opinion?
6. Have you ever heard about mono?
7. The private keys are just used to demonstrate the PoW address
8. You lack intelligence

Hope that answers...

Its just not possible what you are trying to do.

To crack a private key with brute force will make millions of years even on Bitcoin ASICs.

This wont achieve anything except wasted electricity.

It's not the purpose of this coin, please read the website at www.recoverycoin.info and the whitepaper. Also, without incentive there's no effort.

Address generator and ECDSA hash demonstration now available on github: https://github.com/bit-alchemists/RecoveryCoin

For any help on how to build and run, or if you have any question about the code or the architecture please ask in this thread and you will be answered. Also we would appreciate your insights and comments. Why use PoW addresses? Harder to crack, saves space on the blockchain and keeps the coin away from mass trading. Also, while generating the address the targets may be hit (rewards are generated at transaction level and not at block level).

If you cant even explain what your doing and why your doing it and how it helps ect in more then a few sentences you don't deserve my time.

Good bye.

An explanation was already given, assuming that you have general knowledge of cryptocurrency technology.

Dear everyone,
Since this is an opensource project, and after reading your comments we have decided to change the direction a little bit.
The targets will not be e full Bitcoin public keys, but only their 8 leftmost bytes. So nothing will be robbed.
RecoveryCoin will have its value from indicating the strength of Bitcoin's keys against the potential network power, with probabilistic calculations.
Thank you very much for replying to this thread, however harshly.   Kiss

Then what's the point. I don't get why you would want the first 8 bytes? What can you do with that?

You can measure how probable it is to crack a Bitcoin address. This is similar to "shares" in pooled mining.

But how does that make money for you or anyone else unless you take the btc in the address.

You serve the Bitcoin community by telling them when they have to switch to a bigger key size. So without RecoveryCoin, BTC holders might be at risk some day.

Still not following. Spell it out for me please.

Please be more specific.

Big changes are coming and Im prepared fro them. U will invest 300 million dollars in ecdsa attacks and will be rewarded with a small payment coming from a private key retrieved from btc address u control, but don't hope to see more payments coming in because the sending address will be vanished by greedy sharks and brave scavengers.

Rubbish.

You want to do an ico to raise money to rob people of their btc, do I understand this correctly?

ya haha its kinda hard to say WHAT they even need money for ;p

i am down for "Proof of Attack - Earn REC for only attempting to recover Bitcoin addresses"  -- but i still dont see why they will need funding to setup a server for people like at vanitypool where stuff can be posted for people to crack at. seems like that could be done out of pocket, maybe add a 1% fee to the "EDSCA Pool".
course on that note, we already have an open non profit at http://lbc.cryptoguru.org:5000/about that is as i understand it basically an "EDSCA Pool"  (tho not set up for incentives as this maybe could be)

idk, time will tell ;p


But they want to do more then attempt, they want to clean the address out. Correct?

the LBC collider? ya the funds will be claimed, AFAIK, yes. We only work on the "puzzle transaction" there tho, not a free market or service, like this could be

1. We don't need the funds.
2. This pool you've shown is not decentralized, and it is not a cryptocurrency.

ya its not decentralized nor a cryptocurrency, true.

Wrong.

So then why?

my guess is they just want some financial comp for their idea and setting it up (what it seems like). Unfortunately most wont pay for an IDEA, but the service they might

Actually we would prefer to have no funds raised, and to start the blockchain in a completely neutral state.
