Light Clients

On the order of overhead of Bitcoin SPV

Super light sync

• Lodestar is digging into R&D
• eth1 LES informing eth2

Starting now

Light clients are critical to a sharded system so sustainable light client server models are requisite.

• Lightning Fast Light Clients for the Future of Ethereum
• Eth 2.0 Light Clients: How Light is Light?
