Wrapper. http://wrapperproject.com/.

You can read the first version of our whitepaper here.



ICO Link
The ICO (Initial Coin Offer) of 10 Million WRP will be conducted by c-cex.com. You can read the ICO terms here.
The offer will last three weeks, with rewards for early investors. The price schedule will be the following:
  • First week (12/11/16 16:00 to 19/11/16 18:00): 1.05*10^-5 BTC/WRP (30% reward);
  • Second week (19/11/16 18:00 to 26/11/16 18:00):  1.2*10^-5 BTC/WRP (20% reward);
  • Third week (26/11/16 18:00 to 3/12/16 18:00):  1.5*10^-5 BTC/WRP (No reward).

All times are GMT +0.
Any unsold WRA will be burned by c-cex.



The Tech
One of the biggest flaws in Bitcoin-based cryptocurrencies is their pseudo-privacy. Every transaction is recorded in the blockchain and publicly accessible. In a world where confidentiality is a major concern, there's demand for a more privacy-concerned approach to cryptocurrency.
Wrapper is here to fix that. We use a mathematical tool present in fields ranging from Quantum Mechanics to Telecommunications called "Discrete Fourier Transform (DFT)".

 Wrapper differs from other cryptocurrencies by building itself on top of something we call the “Fourier Protocol”. The Fourier Protocol is a way to implement privacy while drastically reducing the size of the blocks in a Bitcoin-based currency. Fourier works by associating each block with a periodic wave of period T0.
 
Periodic waves have the following properties:
They can be written as a sum of sines and cosines.
They are, in the frequency domain, represented by discrete functions.
 
The protocol uses these properties by encoding transactions as waves and summing them to the wave of their corresponding block, reducing drastically the size (in disk) needed to store each block.

A typical wrapper transaction between Bob and Alice has 4 phases:
1 -  Bob, who’s sending WRP to Alice, signs the transaction with his private key and Alice’s address.
2 -  Bob tells the other nodes about the transaction, adding two waves to the block wave: one with fundamental frequency lower than BLOCK_CUT_FREQUENCY, and one with fundamental frequency higher than BLOCK_CUT_FREQUENCY. The first one tells Alice there’s a transaction in that block for her. The second one is the transaction itself.
3 - Alice gets the block and analyzes the wave, checking if there are any transactions for her.
4 - If there are any transactions to one of her addresses Alice decodes them and the coins appear in her wallet.
 
An extra layer of security
Besides the privacy added by Zerocoin, which is already a very well thought-out and academically interesting protocol, you will have the option to hide your transaction using an extra layer provided by Fourier. If selected, Fourier Privacy will hash the frequency of the wave that tells there is a transaction in a block for a certain receiver, in a way only the holder of the receiver’s private key can decode. Making it virtually impossible (as per computing power in 2016) for another system element to know there’s a transaction in that block for that receiver.
 
What are the disadvantages of the fourier protocol?
The most relevant is that it takes 4 to 5 times longer to index a block in fourier based blockchains. This is due to a lot more computation time being needed to process:
  • The convolution needed to low pass the signal in a block and check for transactions to a given user.
  • The discrete fourier transform required to read a block.
  • The inverse discrete fourier transform required to add a transaction to a block.

This means that, when you open your wallet for the first time, it will take longer to synchronize with the network, although it shouldn’t feel very different throughout the rest of the implementation.


Use Cases
The Wrapper Team is building and I2P market that uses Wrapper as a transaction currency.
