"Sync committees", which allow light clients to easily sync up with the header chain with very low computational and data cost. The goal is to make a light client easy and efficient enough that it can be run inside any environment (mobile device, embedded hardware, browser extension, and even inside another smart-contract-capable blockchain)
Incentive accounting reforms. This includes a few changes:
Storing actions that were taken during the current and previous epoch in a more efficient bitfield format instead of storing
PendingAttestationobjects, reducing spec complexityMaking the "inactivity leak" quadratic per validator instead of quadratic globally, and in particular make it insignificant for validators that are participating >80% of the time. For example, pre-Altair, if a chain stops finalizing for 2 weeks, fully inactive validators lose ~11.8% of their balance and validators active 75% of the time lose ~3.1%. Post-Altair, the fully inactive validator's loss would be ~15.4% but the 75% active validator's loss would only be ~0.3%. This makes inactivity leaks more forgiving to honest-but-imperfect validators.
Bug fixes to reward accounting (eg. giving proposers a ~1/8 share of all rewards instead of just a ~1/8 share of one small piece of rewards, and ensuring that the rewards under perfect performance actually do add up to the full base reward)
Penalty parameter updates, making both inactivity leaks and slashing somewhat more punitive than pre-Altair, though still less punitive than their eventually-intended values.
