1/ Replicated Security is a much-awaited @CosmosHub feature!

Coming with the Lambda Upgrade, currently in voting period.

Considering the importance of this upgrade for #ATOM future...

Today’s thread will address community feedback, starting with Validator Cost & Slashing 👇

2/ Validators will need to run all consumer chains that are approved by governance or face downtime slashing. This is essential to preserve the high-security properties of Replicated Security.

Some are concerned about the cost of running additional consumer chains.

3/ @informalinc, the team leading the development of replicated security are taking several steps to address validator costs:

First, consumer chains will set their downtime window to 3+ days, meaning that validators can be down for a long time before receiving a downtime jail.

4/ This solution will reduce the risk of jailing, the increased leniency means that validators can run consumer chains with less redundancy, cutting costs. This will not pose a problem for the reliability of consumer chains.

5/ Second, @informalinc will help the first consumer chain teams prepare financial projections quantifying the rewards that can be expected by the validators and delegators of the Cosmos Hub. This will help the community decide whether a given consumer chain is worth approving.

6/ Some community members were concerned that a malicious consumer chain could send falsified slashing packets to the Hub, causing validators to be slashed unfairly. This is one of the main reasons that consumer chains need to be audited before the governance proposal.

7/ Although this scenario is very unlikely, it is a valid concern and additional protection is already implemented through a throttling mechanism to slow down the slashing process to allow time to stop this attack.

8/ To make things even safer, changes have been made so that slashes for double signing (the most serious type of consensus offense with the highest punishment) need to go through one additional step of being approved by governance.

9/ This will provide extra safety in the early stages of Replicated Security’s launch.

More information regarding this measure can be found in the Cosmos Hub Forum:

10/ The teams working on the Hub are listening to community feedback and prioritizing security to make sure that the launch of Replicated Security will be a success!

This is the dawn of a new era of development around the #ATOM ⚛️
