This is a working group under the IEEE TEMS Technical Committee (TC) on Blockchain and Distributed Ledger Technologies focusing on Scalable Blockchains & Parachains. The key focus will be on understanding:

• How Blockchain technologies can be scaled to an increasing number of transactions;

• How multi-layered Blockchains can be used to support emerging applications -- such as in Internet of Things, Cyber-Physical Systems and embedded environments
