Thank you @dgusakov for the amazing and well put together proposal.
I would also point out that suggested bond structure aligns with the risk mitigation approach, suggested in Risk assessment for community staking framework, providing exceptional risk mitigation, in particular::
1. The proposed bond is sufficient to transfer the risks associated with any operational mistakes.
For any actor with up to 8 600 ETH of capital put as a bond (~ 6 641 validators), the bond completely covers:
- 3 months of offline period
- Possibility of slashing after
2. The Cost of an Attack for any intentional malicious actor (up to 16 700 ETH in bonded capital) is twice as high as the potential impact on the protocol
Pemisionless & Community Stakers Attack multiplier curves are almost completely coincide on the possible attack scale due to difference being only in initial bond volume
3. Bond curve form incentivizes registering validators on one Node Operator drastically reducing reasonable stealing opportunities, and any possible consequences
With inclusion of transaction costs into consideration, even actors considering implementing EL stealing strategy are incentivized to utilize all capital on one node operator for any amount of capital as the capital efficiency curve is increasing on all observed values
Evaluation provided under risk-averse assumption on level of CL & EL rewards (2.85% and 0.55%)
Coupled with great conditions for the Node Operators I support this proposal as a way to ensure opportunities for Module growth, while ensuring sufficient risk mitigation and sustainability for the DAO.
