Blockchain Revolution

BAIRBNB VERSUS AIRBNB
bAirbnb is a distributed application (DApp), a set of smart contracts that stores data
on a home-listings blockchain. The bAirbnb app has an elegant interface: owners can
upload information and pictures of their property.

The platform maintains reputation
scores of both providers and renters to improve everyone’s business decisions.
When you want to rent, the bAirbnb software scans and filters the blockchain for
all the listings that meet your criteria (e.g., ten miles from the Eiffel Tower, two
bedrooms, four-plus star ratings only). Your user experience is identical to that in
Airbnb, except that you communicate peer to peer on the network, through encrypted
and cryptographically signed messages not stored in Airbnb’s database.

transaction entirely off-chain, but you are better off completing the transaction on-
chain for a few reasons.
Reputation: Because the network records the transaction on the blockchain, a
positive review from each user improves your respective reputations. The risk of a
negative review motivates each party to remain honest. Remember, people with good
reputations can use the same persona across multiple DApps and benefit from
continuity as a good person.
