 ## Pre-reading
 
 Before the program, you should be familiar with some general concepts from Ethereum and computer science. If you are not familiar with basics of using Ethereum or have non experience with software development, we recommend gaining at least some understanding of following:

+
+During the second week, we will dive into the Execution layer of Ethereum. 
+
+Come to see the presentation by [lightclient](https://twitter.com/lightclients/) on [Monday, February 26, 4PM UTC](https://savvytime.com/converter/utc-to-germany-berlin-united-kingdom-london-ny-new-york-city-ca-san-francisco-china-shanghai-japan-tokyo-australia-sydney/feb-26-2024/4pm).

+
+## Pre-reading
+
+Before starting with week 2 content, make yourself familiar with resources in [week 1](/eps/week1.md). 
+
+Additionally, you should read through the following documents to prepare for the presentation:
+* [Nodes and clients](https://ethereum.org/developers/docs/nodes-and-clients)
+* [Ethereum: mechanics](https://cs251.stanford.edu/lectures/lecture7.pdf)
+
+## Outline
+
+###  Overview of the execution layer node
+* Block validation
+    * in overly simplistic terms, ELs process the state transition
+    * each transaction is validate by the client, executed, and it's result accumulated into the state trie
+    * there are additional mechanism which also must be updated each block, such as the EIP-1559 base fee, the EIP-4844 excess blob gas, the EIP-4844 beacon root ring buffer, beacon chain withdrawals, etc.
+    * new nodes must also be able to join the network without too much friction, so ELs provide efficient syncing mechanism to bootstrap others
+* Block building
+    * ELs also build blocks based on transactions they see around the network
+    * this requires a tx pool system over p2p
+
+### State transition function
+* header validation
+    * verify merkle roots
+    * verify gas limit
+    * verify timestamp
+* block validation
+    * walkthrough [`Process(..)`](https://github.com/ethereum/go-ethereum/blob/master/core/state_processor.go#L60) in `state_processor.go`
+
+### EVM high-level
+* stack machine intro
+* look at simple programs
+* review different classes of opcodes: stack/mem manipulators, env getters, ethereum system operations, etc.
+
+### p2p high-level
+* p2p serves three main things
+    * historical data
+    * pending txs
+    * state
+* discuss snap sync
+    * phase 1: downloading snap tiles
+    * phase 2: healing
+
+### JSON-RPC
+* the "interface" to ethereum
+    * the vision is that all clients provide the exact same API and users can run any client the choose and have perfect integration with all tooling
+    * not quite there, but we are fairly close
+* review main RPC methods
