How Erasure Coding used in hadoop3 and how they achieve fault tolerance with it?

As per the Hadoop 3.x release notes, they have introduced Erasure coding to overcome the problems with storage.

Erasure coding, a new feature in HDFS, can reduce storage overhead by approximately 50% compared to replication while maintaining the same durability guarantees.

can someone explain me how Erasure coding is used in fault tolerant way with less space overhead?
