Blockchain is nothing but a record of transactions. A record which is distributed among thousands of computers around the world instead of one person controlling it.

All those thousands of computers have to reach a consensus to make a transaction valid.

Each transaction made, is broadcasted to the network and the validity of those are checked by complex algorithms.

If it turns out to be valid then they are added to the record of previous transactions. The chain of transaction thus formed is called the blockchain.

With such pathbreaking advantages the blockchain powered P2P payment apps have already seen huge investments made by behemoths such as JP Morgan Chase & Co.

They have already filed a patent application with the US Patent and Trademark Office.

So, now is the best time to invest your time and money to develop a robust P2P payment app to gain the first mover advantage.

P2P contactless payments are still a niche segment which will undergo humungous transformation in coming years and you must want to be the first to adapt to those advantages.
