# Note
1. PBS: separate block proposer and block builder tasks in protocol
beacon block <- intermidiate block <- beacon ...
2. Data Availability Sampling: Only download a small piece of data to verify
2D KZG scheme: erasure codeing gen extensions
3. Verge: new accumulator i.e. Verkle tree in place of Patricia: SNARK verkle proof, state expiry, stateless clients, easiaer state verification
## Consensus
1. SSLE Secret Single Leader Election
current beacon chain proposer is predictable, need privacy
2. fork choice and confirmation improvements: determine finanlity in 1 or 2 slots
3. new EVM bytecode
separate code and data=> easier onchain code analysis
? so w/o this change, code analysis is hard?
