V9 Lambda Upgrade

The Cosmos Hub is upgrading its security system with a new feature called Replicated Security. This will allow the Cosmos Hub to provide its strong security to other blockchains, which are called 'consumer chains'. The cost to censor or control a consumer chain with an economic attack is the same as the cost to censor or control the Cosmos Hub itself. This means that consumer chains can benefit from the Cosmos Hub's security without having to maintain their own validator sets.

Replicated Security works through the IBC protocol. Consumer chains receive periodic IBC packets containing the up-to-date validator set of the Cosmos Hub and use this to update their own validator sets, effectively replicating the Hub's validator set. This means that the Cosmos Hub's validators can validate multiple chains at once with the same stake.

In exchange for this service, consumer chains are expected to send a portion of their fees and inflation to the Cosmos Hub validators and delegators. These tokens will then be included as part of the Cosmos Hub's staking rewards.

​

This upgrade will add the necessary code to allow for replicated security on the cosmos hub, allowing smaller consumer chains to share in the security of the already established Cosmos hub.

ATOM delegators will receive staking rewards from each of these consumer chains using replicated security in the form of either their native token if they have one or transaction fees generated by the consumer chain.

example:

Chains A,B,C,D submit proposals to use replicated security and are accepted by delegators voting yes.

Chains A, B & C have native tokens, chain D does not.

So by staking ATOM you will now receive the regular ATOM staking rewards currently at 21.5% APR in ATOM + Chain's A native token + chain's B native token + chain's C native token + 25% of chain's D transaction fees converted into ATOM.

So ATOM delegators will be receiving tokens from any consumer chain leasing security from the Cosmos HUB through replicated security.

​

The proposal also states that this is one of the first steps in building the ATOM economic Zone

The ATOM economic zone

It is anticipated that consumer chains using Replicated Security will collaborate closely in an 'ATOM economic zone'. This is expected to have a snowball effect, with the Cosmos Hub securing a growing group of high-value decentralized protocols. Already, some prominent projects such as a smart-contracting platform, an AMM, several liquid staking providers and others have expressed interest in using Replicated Security from the Cosmos Hub.
Replicated Security can also be used to further the cause of “Hub minimalism”. Any new features to the Hub, even if they are core to the Hub's functionality, can be launched as consumer chains. This allows the Hub to scale better and separate release cycles, enabling faster deployment of new features.
