New York-based ShelterZoom plans to launch a real estate application that will lets buyers and sellers transact deals over a blockchain-based network, which could make purchasing a house as easy as pressing a button on a smartphone or tablet.

Set to go live in the first quarter of 2019, the application allows sellers, buyers and real estate reps to see all offers and acceptances in real time online.

"Our current platform is already helping agents, buyers, sellers and renters make the big leap to technology's present, and we're excited to initiate another industry sea change in early 2019," Chao Cheng-Shorland, ShelterZoom's CEO and co-founder, said in a statement.

The start-up has been piloting its application with real estate firms over the past year; it's now being tested by more than 90 brokerages around the world.

The app required integrating some HTML code on the website, but was fairly straight forward, he said.
