Survey v1.0.0.
1.1 We currently are on v0.8.1.
1.2 Yes.
1.3 No.
1.4 N/A
1.5 It was networking due to gossipsub. We're going to use lighthouse's libp2p fork for the gossipsub functionality, so it's not a blocker any more.
1.6 We weren't doing a lot in terms of optmization until now. But given this seems to be a well-researched topic by other client teams, I think it shouldn't be hard.
2.1 Yes.
2.2 No. We use native libp2p.
2.3 We're using a simple mDNS discovery and Kademlia, the same approach used by Substrate. Given lighthouse has implemented discv5, that's on our todo list next.
2.4 Our current implementation for networking is rather simple -- clients send each other a status message, and if it indicates a newer head, sync is started.
2.5 We currently use tcp-ws-secio-mplex-yamux.
2.6 Not yet. We're using a simple status sync (see 2.4), but we're planning to conform to the wire protocol.
3.1 Not yet.
3.2 Yes.
3.3 No.
3.4 No.
3.5 We use simple full sequential.
3.6 No.
4.1 Our trie library has support immutable data sturcture, but it's not yet integrated. We currently just store the full copy.
4.2 Store every block.
5.1 We haven't yet implemented attestation broadcasting.
5.2 No.
6.1 No. We don't yet have tests for fork choice.
6.2 Unoptimized spec.
7.1 Yes. We pass all spec tests.
7.2 v0.8.1
8.1 We currently just import block first, sending a status, and wait for other peers to sync the block. This is rather inefficient so we definitely plan to improve.
8.2 So we transition state completely.
9.1 No. We haven't implemented attestation propogation.
10.1 No.
10.2 Yes.
10.3 Rely on system clock.
11.1 No.
11.2 No. We don't yet have API endpoints.
11.3 No. We don't yet have logging.
11.4 N/A
12.1 No.
12.2 Looks fine.
13.1 Yes.
13.2 No.
14.1 It passed v0.8.1. We haven't upgraded to 0.8.2.

14.3 N/A
14.4 No.
15. Chain Start (reference doc)
15.1 We currently only support loading genesis spec (2).
15.2 Keys we generated are not reproducible yet.
16.1 Yes. However the mainnet configuration is currently slow for us.
16.2 N/A.
16.3 Compile-time.
17.1 No.
17.2 No.
17.3 No.
17.4 Only Linux is tested. However adding support for macOS and Windows should be easy.

18.4 Our life have been significantly easier after spec freeze. Nothing else!
