Measuring workers in PoS networks
PoS networks usually require worker nodes to some some work in order to keep or increase their stake. Actually measuring the amount of work performed by each node in a secure and decentralized way is a huge challenge.
BLS Hardware Security Module
BLS signatures will become one the fundamental building blocks for ETH 2.0. However, this particular scheme is not yet supported by comercial HSM. By developing and open source BLS HSM we give the opportunity to ETH 2.0 node operators to easily incorporate higher security measures.
