Graphene V2 Report Shows Mass On-Chain Scaling Progress, 1GB Blocks Possible on Basic Hardware

The research team behind Graphene block propagation has released an update on progress on Graphene V2, showing evidence of massive on-chain scaling possibilities.

In a recent post on Reddit, the University of Massachusetts research team published an update on their scaling research in conjunction with the Bitcoin Unlimited team:

“For the past six months, our team at UMass (in conjunction with the Bitcoin Unlimited team) has been working on various improvements to the Graphene protocol, which we’re calling “Graphene v2″. The project is broken into two phases. Phase 1 introduces various security and performance improvements, while phase 2 implements failure recovery and mempool synchronization.”

Included in the report was a test to produce a series of blocks with varying transaction volumes, and attempt to compress the blocks as much as possible to facilitate propagating across the network. Some of these compression attempts delivered significant results:

“The report includes a test that we ran on over 500 sequential blocks from mainnet. During that test, we experienced 2 decode failures and were forced to request missing transactions 4 times. The overall mean compression rate was 0.995. For blocks with more than 1000 transactions, the mean compression rate was 0.998. The largest block, containing 2545 transactions, had a compression rate of 0.999.”
