https://medium.com/emotiq/emotiq-development-update-28-03-2018-aafbceeac5bdIts easy to fall into a pattern of developing behind closed doors, beyond the reach of the unrelenting sun. What can we say? Were busy.
But we also appreciate the importance of keeping our community up to date so well be releasing periodic development updates to provide a glimpse of the magic being made, like secretive notes slipped beneath ironclad doors.
Crypto: pairing-based crypto is now available
Emotiq now has pairing-based cryptography (PBC) which relies on libraries by Boneh & Lynn (Stanford), and those developed internally. As a result, we now have short BLS signatures, and the possibility to support hierarchical deterministic wallets, with all the advantages promoted by BIP-32 (but without the security risks). Emotiq can also support more conventional ECC crypto using only one of the two curves involved in PBC pairings.
Consensus: single-pass CoSi signatures with BLSEmotiq now uses Boneh-Lynn-Shacham (BLS) signatures in collective signing protocol instead of Schnorr signatures, to avoid the double round-trip through the communication tree to aggregate a collective signature.
And planned for the next two weeks
We are putting together a strawman Emotiq full-node implementation, which will be based on the full stack of our crypto primitives and protocols:
Pair-based cryptography primitives, including support for BLS signatures and PVSS under Bilinear pairings
Enhanced co-signing (CoSi) protocol
Distributed randomness protocol, RandHound, enhanced by using PVSS bilinear pairings
Zero-proof privacy protocol based on Bulletproofs
The full-node software will be packaged and delivered as binary, so anybody courageous enough may explore it on macOS or Linux.
In conclusion
Were
real busy.
