  Wibson is a blockchain-based, decentralized data marketplace that provides
individuals a way to securely and anonymously sell information in a trusted
environment. The combination of the Wibson token and blockchain-enabled smart
contracts hopes to allow Data Sellers and Data Buyers to transact with each
other directly while providing individuals the ability to maintain anonymity as
desired.
  The Wibson marketplace will provide infrastructure and financial incentives
for individuals to securely sell personal information without sacrificing
personal privacy. Data Buyers receive information from willing and actively
participating individuals with the benefit of knowing that the personal
information should be accurate and current.
  We present here two different components working together to achieve an
efficient decentralized marketplace. The first is a smart contract called Data
Exchange, which stores references to Data Orders that different Buyers open in
order to show to the market that they are interested in buying certain types of
data, and provides secure mechanisms to perform the transactions. The second is
used to process payments from Buyers to Sellers and intermediaries, and is
called Batch Payments.
