Here is a list of recommended challenes on play.picoctf.org/practice for you to work on.
If you are stuck, it's often a good idea to move on to another challenge and come back later.
Always feel free to work on any challenge that strikes your fancy. These are ones I have taken a look at.

Execution of the downtime slasher with a 8640 blocks block window, approximately 12 hours, requires ~20.8 million gas. With a gas limit of 20 million on the Baklava network, it is not currently possible to execute this function.
Downtime slashing is an important measure to ensure the stability of the Baklava network, as there are no incentives against abandoning elected validator nodes. At the time of writing there are 13 elected validators on the Baklava network which appear to be abandoned. If this number exceeds 1/3 of the elected set, currently 19, the network will stall
This proposal will call the function DowntimeSlasher.setSlashableDowntime(7200) to set the slashing window to 7200 blocks, approximately 10 hours, which will execute with approximately 17.3 million gas, within the gas limit.
After this proposal in enacted, downtime slashing can be used to slash offline validators, which will remove them from their groups and from the elected set if the o

The notes below describe the approach in designing and writing the initial reference implementation of Handshake. This is not a prescriptive document and should not be used as such. This document's goal is to provide a referenece on the rationale and initial design of the protocol.
The foundation for the internet's security has relied upon trusted Certificate Authorities (CAs) which attest that a user is connecting to the correct server or node. This has created a reliance upon a handful of trusted actors, many of
