+### ePBS, Prysm

 - **ePBS**. Project at prysmaticlabs mentored by [@potuz](https://x.com/potuz_eth) and [@terencechain](https://x.com/terencechain). We currently have a fully specified [ePBS spec](https://github.com/potuz/consensus-specs/pull/2). And are actively working on a Go implementation as part of Prysm [here](https://github.com/prysmaticlabs/prysm/pull/13917). We plan to have a fully working PoC in the comming months and production code ready by exposition time in Devcon. Reading material includes some comprehensive documents.

 As for working conditions, we would not have weekly calls as in previous cohorts, but rather focus on code review and implementation work. Fellows are expected to carry their own research and asynchronously request help/discussions on Discord. Some areas of independent interest could be implementation of variations of ePBS like *slot auctions* or *execution tickets*. Please refer to [Barnabé's doc](https://mirror.xyz/barnabe.eth/QJ6W0mmyOwjec-2zuH6lZb0iEI2aYFB9gE-LHWIMzjQ) for a high level introduction.

+### JSON-RPC in Geth
+
+By Sina 
+
+⁃ Implementinng `trace_*` namespace, and most importantly [trace_filter]([https://docs.alchemy.com/reference/what-is-trace_filte](https://docs.alchemy.com/reference/what-is-trace_filter)) in geth. Currently there is only debug_trace, there are basic building blocks of tracers but trace filter needs an additional index for the database.
+
+⁃ Specification and implementation of `eth_getTransactionBySenderAndNonce`, see https://github.com/ethereum/execution-apis/issues/494
+
+⁃ Error codes in the JSON-RPC API. This one needs a lot of cross-client communication. Standardizing error codes across clients json-rpcs 
+
+⁃ Benchmarking APIs via [flood](https://github.com/paradigmxyz/flood) and optimising the methods in various clients, compare across clients (not only geth)
