Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Gas is the cheapest it's been in a long time. Imagine that this will be the norm a year or so from now
There's really no "forcing", in sharding validators are randomly assigned to a shard, similarly to how they're currently randomly split up into committees that attest to the validity of blocks. There's no centralizing force: the randomness into the process is provided in a decentralized fashion by the validators themselves, through a mechanism called RANDAO.

Explaining Ethereum's consensus mechanism after The Merge
Article author here.
Great questions, should have explored the randomness beacon more. Ethereum uses [RANDAO](https://github.com/randao/randao), which is a distributed commit-reveal scheme where participants in the generation post a hash of their data on the commit portion and then at a later timestamp reveal the data preimage, and get slashed if they do not reveal a correct preimage. Then all participant data is aggregated together. This means if there is at least one honest participant the generation will be random.
A supermajority (2/3rds) of validators is required to finalize a block, in case of a 50-50 network partition blocks would stop being finalized and attestation rewards would stop. Non-participating validators would slowly leak stake through the inactivity leak until online validators once again had a supermajority. This is the "self-healing" mechanism that allows both safety and liveness.

How does Eth 2.0 PoS choose block proposer randomly?
https://github.com/randao/randao Is this what you’re referring to? It says it’s a DAO.

Proposals on random
So according to this generating randoms for the eth chain is like validating but with shorter cycle and more profitable. Now I have even more questions like: How can I participate Is there software like prysm for using random contracts What is the minimum stake for random contracts Is anyone doing this, is it wort it

Suggestion for multiple-user seed
Thank you Eric, I discussed it too in the PoolTogether discord and got this reponse from one of the founders: " What you're describing is a version of "RANDAO". See here: https://github.com/randao/randao Really, the VRF is an unnecessary step if a seed is being selected by all participants If you look through the above project, you'll see they try to handle a few corner cases like if a user refuses to reveal their seed, or preventing a seed from being used twice The trouble with Randao is the amount of coordination and expense that it incurs. " I understand ETH 2.0 will be doing some implementation of RANDAO along VDFs for the Beacon chain. Algorand implements this too. I found this talk from Justin Drake talking about this algorithm: https://www.youtube.com/watch?v=zqL_cMlPjOI
