Stellar

Stellar is a platform that connects banks, payments systems, and people. Integrate to move money quickly, reliably, and at almost no cost.

Stellar can currently transact around 2000 transactions per a second with no real upper bounds. The more nodes added to the network the more it can support. This means you can do a transaction with the same safety benefits of Blockchain but in about 1–5 seconds. That’s about 3,000x faster than Bitcoin in comparison.

In addition Stellar has a built in exchange, where you can trade assets using same transaction speeds mentioned above. This exchange is built into the network so it’s part of the distributed system.

On top of all that, they have a rich development platform that’s substantially more mature than most other crypto currencies. They have multiple sdk’s in multiple languages, as well as very thorough and mature documentation.
