At this point I’m too afraid to ask what’s considered as sidechain, L1, L2, and L0?

I thought polygon is an L2 for the longest time, but a couple of tweets from experts suggested otherwise

It’s somewhat debated. Polygon does make snapshot commitments to Ethereum, but whether this is considered inheritance of L1 security (and thus making it a form of L2) versus a side chain operating independently with interoperability is kind of grey. I lean towards L2, but others may disagree.

Anything that does not commit snapshots to Ethereum but bidirectionally bridges would be a side chain rather than an L2. BSC would be an example of this.

🤔 Is there something that you know is strictly(not on the grey) sidechain, L0, L1, L2?
