Dan Boneh didn’t file BLS patents, and is not aware of patents on BLS.
Sorry I don’t think it’s online yet. The info came from discussions with Eli Ben-Sasson. As I understand 80bK is the size StarkWare got for the equivalent of a single Zcash transaction. There are a couple of factors that may increase the size to the 100kB-200kB range for us:
- The size of a STARK scales roughly logarithmically with the length of the computation, and our aggregate signatures do more computation
- There’s a tradeoff between size and prover/verifier time, and it may be favourable to increase proof sizes a bit.
The beacon chain is a sidechain to legacy chain in the sense that:
- Beacon chain blocks contain a reference to a legacy chain block.
- If the legacy chain reorgs then the beacon chain must reorg accordingly.
At some point in the future the legacy chain can become a sidechain to the beacon chain.
