#baby $BABY Today I spent some time reading about how Babylon handles Bitcoin checkpointing, and one detail really stood out to me.
At first, I wondered why Babylon uses two Bitcoin transactions for a single checkpoint. After reading the documentation, it made sense. A standard Bitcoin OP_RETURN can only hold up to 80 bytes, while a Babylon checkpoint includes multiple pieces of information like the epoch ID, checkpoint hash, signature bitmap, and aggregated BLS signature. The complete checkpoint is simply too large for one OP_RETURN.
Instead of changing Bitcoin's rules, Babylon works within them by splitting the checkpoint across two transactions. I like this approach because it respects Bitcoin's existing design while still enabling secure checkpointing.
Learning small implementation details like this gives me more appreciation for the engineering behind blockchain infrastructure.
