+
+# Client Team Updates
+## EL
+
+* **Nethermind**: 
+  * Focused on Shutter and Pectra
+
+* **Erigon**: 
+    * Agreed to add Shutter support to Erigon v3
+
+* **Geth**:
+  * The difficulty code had to be rewritten, but doesn’t completely work yet
+  * Can still connect to Nethermind nodes and sync blocks (using snap sync)
+
+
+* **Reth**: 
+  * Stuck on testing post-merge on a devnet
+  * Customizability for consensus / custom properties in blocks is still fairly lacking in Reth
+      * Cannot add the step and signature fields
+      * For genesis this is only an issue on devnets with TTD = 0
+  * Upgrading from 1.0.0 to 1.0.1 produced a huge diff on our side, highlighting some potential long-term maintainability issues
+  * Not quite clear to Lion what needs to be implemented (we just need verification, not capability to produce blocks etc)
+
+
+# Chain Infra
+
+* **Gateway**
+  * No updates
+
+# Innovation
+
+* Shutter
+    * Launched last week
+    * ~5% of validators producing blocks (one every ~3 minutes)
+    * There’s a lot of latency until the validator sees the key, which can result in missed blocks
+        * If the key is too late, a normal block is produced instead
+    * Want to onboard more validators and work on client diversity too
+    * How to do block builders for Shutter?
+        * Currently keys are public anyways so it’s fine, but there were talks about encrypting them for specific validators
+
+
+# Testing
+
+* Hive
+    * Up to date with upstream
+    * Improved the repo to make it easier to add new tests and new clients
+* Ethereum/tests
+    * No updates
+
+
+# Research
+
+* Gas markets
+    * 3 open fronts
+        * Research: deciding on the primary sell mechanism
+            * Potentially the most difficult part
+                * Sell vs strike price, difficult to calculate on-chain 
+        * “Gas Markets” group on Telegram
+     * Prove that it’s safe, as we’re messing with EIP-1559
+        * Instead of mining, we’ll refund the costs to the users
+        * Miners could buy the futures, and then miners get reimbursed, which may break things (and negate the base fee burning introduced by EIP-1559)
+  * Execution: how to consume this
+    * Buy the option
+    * Send specific transactions in a way that will get you a refund
+        * Currently doesn’t use pay masters
+        * We need to work on good dev experience for this
