Comparison of Babylon protocol and EigenLayer

Babylon chain (a chain built on Cosmos SDK) as the middle layer;

PoS blockchain as a secure consumer (such as other Cosmos zones);

An important design consideration is that Bitcoin has very limited data capacity. In this case, the Babylon chain has multiple functions:

It aggregates the checkpoint streams of many PoS consumer chains, so only one checkpoint stream needs to be inserted into the Bitcoin network to timestamp events in all consumer PoS chains at the same time.

Its checkpoints in the Bitcoin network can be made compact using cryptographic techniques (such as aggregate signatures).

It receives checkpoints from consumer PoS chains through the IBC protocol.

It checks the data availability of the checkpoints of the PoS consumer chain so that attackers cannot timestamp unavailable data.

This structure can help Pos chains improve security, such as resisting long-range attacks.

Babylon consists of two parts: the Bitcoin timestamp protocol and the pledge protocol. Since Bitcoin is not Turing complete, many processing tasks require a separate chain to complete. Therefore, the Babylon protocol has its own chain, which is built through the Cosmos SDK. Correspondingly, it has its own chain verification node. It also includes independent EOTS Manager and Finality Provider, etc.

EigenLayer is essentially composed of a group of smart contracts that can accept user pledges and manage AVS contracts, etc. The underlying layer is executed by the Ethereum network and guarantees security.
