This new environment and emerging staking economy enable an explosion of new protocols. However, Wallets, Exchanges, and Custodians will struggle with the overhead of servicing those new protocols and will have the most to lose if their credibility is lost.
The temporarily muzzling of major companies and famous names didn't affect unverified Twitter accounts.

A centralized entity grew to the point of holding 53% of the network voting power. Cosmos Hub set up Game of Stakes (GoS) testnet, the first participatory research program to simulate a live adversarial environment and to observe how collusion and deception interact with the incentive layer of a BFT Proof-of-Stake system.
