Brief intro and background to Brett McDowell, Hedera Chairman

How does it work with Swirlds having Mance and Leemon and the staff and not at Hedera?

Leemon, can Hedera or the Governing Council freeze an account?

How will we be able to stake HBAR? It is on roadmap for Q2, why did it move from last year, and why don't we hear any details? Your marketing team needs to put out information about staking. More details

TPS on the network is less than in the past. Mance promised step function last year. Why is it delayed, and when will we see this on the network? - Submit your project

What is the adoption of smart contracts looking like?

Can you explain the process for donating hbars to Ukraine? How and why was that decision made?’

What are your plans to ease the migration of a dApp from Ethereum (and others ) to the Hedera platform?

If you can shed some light on why council members is taking so long to reach 39.

What will be the hardware requirements to run permissioned community node?

How do the 39 council members choose who as an individual will represent their seat on the council? Are there qualifications? Can a council member send more than one representative?

Let’s say in 2024 Hedera generates 1 Billion USD in fees. What happens to the fees? Do the nodes get enough to cover their costs and make a small profit? Does the Governing Council? Is any paid to Hbar holders? Please explain.

Will Swirlds be able to do different marketing than Hedera has been able to do? For example, can Swirlds promote Hbar and what you can do with Hbar?

Post implementation of sharding, will the shards be based on specific geographical locations or the nodes in each shard be selected at random?

Is Ken Herzinger in attendance at Hedera council meetings because you have always been looking to remain compliant with whatever the SEC regulations appear to be?

Is there a correlation between tps and energy use? Do we expect to see a significant increase in energy when we have a significant increase in tps?

The Council members have a duty to each other and their companies. Their companies use our great technology and enjoy the benefits of a low Hbar price to keep their opex low. but investors would benefit from a higher Hbar price. How do you resolve the tension?

With both the Hbar foundation & Hedera having a fund which is targeted toward expanding the network, what is the split in goals between the two instItutions? It seems like Hedera's marketing efforts are centered mostly around conferences, whereas the Hbar Foundation's efforts are centered around dev funding, but isn't a big part of the conferences things like hackathons? What's the purpose of the split?

Leemon can you go into details about the technical controls that are in place to ensure the network can't be forked now that it will be opened sourced?

How would Hedera comply with a Government sanction? - More details

As the network scales and the usage increases there will be need to minimise the impact of minority of dis-honest users. Are you considering to work and introduce the alert system in Hedera network. For users to be able to instantly report suspicious accounts?

Will Hedera continue to host valuable Town Hall updates on quarterly basis, upon team transition to the Swirlds
