# Week 12 Update

**Status**:

- Updates to genesis code for `eth2-testnet-genesis`
- Encountered MacOS issues, fixed `operation not permitted error` in [terminal](https://osxdaily.com/2018/10/09/fix-operation-not-permitted-terminal-error-macos/)
- Meeting scheduled 5 October with mentors to review draft PRs and align on approach to Lodestar code
- Draft [genesis script](https://github.com/atkinsonholly/lodestar/pull/2) (Holly) + [retention script](https://github.com/atkinsonholly/lodestar/pull/1) (Adedamola)
- [x] Genesis script uses eth2-testnet-genesis to generate a new genesis.ssz at a specified out dir
- [ ] Checkpointz and Lodestar ephemery flags in progress - see notes below
- Manual draft genesis script TODOs (see PR) include:
- Iteration calc

Questions relating to:

**GENESIS**
- Approach to out dir
- Validator input
- Approach to using eth2-testnet-genesis repository by Protolambda (I can't find anything in Lodestar already that would perform the equivalent, unless I should code the ssz from scratch)
- Paths
- Fix / validate input types
- Iteration is 95 instead of 96

**RESET**

See Adedamola's [dev update](https://hackmd.io/WBAtfKu3RGyUw__DFw16Fw?view)

**Next steps**:
- Review [how directories are created in Lodestar](https://github.com/atkinsonholly/lodestar/tree/unstable/packages/cli/src/paths)
- Meeting notes below

Genesis (Holly)
* Use checkpointz for checkpoint option “genesis checkpoint sync” usually from latest finalised checkpoint, but we will use the genesis epoch
* Learn about checkpointz! Verify feasibility for using this with ephemery :)
* Second option is to use 
ephemery.dev url is the “backup download option” (already implemented)
* Third option to generate genesis with my script using another flag
* Fourth option to generate with a flag to override with custom path to genesis.ssz provided by user [developer]

Reset (Adedamola)
* Need to start + stop Lodestar from inside the client
* Look at packages/cli/src/cmds/beacon/handler.ts

Next steps
* Talk to EF devops about checkpointz (pk’s colleague) as needed;
* Validate whether it possible to use with ephemery (Holly)
* Connect with Lodestar (Mario will connect us on TG)
* Genesis:
* Ask Lodestar for feedback on overall approach to ephemery code
* Changes to config + cli (similar to Holesky)
* New ephemery package
* Flags
* Reset:
* TBC what questions we have for Lodestar
