scale ethereum with snarks
Thanks for the code. Very helpful to understand the details. I have one question though: >In order to ensure this, we pass every updated leaf to the smart contract so...
Each public input that is passed to the snark costs ~ 40k gas. We want to reduce this by hashing together all the inputs inside the EVM and then hashing...

I've been looking at the preprocessing behavior of the Python test case in order to wrap my head around the interface to this library. There is some logic that, according...
We want to use ethsnarks gadgets wherever we can. This can be 1. The sha256 hash function 2. The eddsa signatures 3. https://github.com/barryWhiteHat/roll_up/issues/33 4. Switch the groth16 prover and verifiyer...
## Proposal Implement an account model with arbitrary-denominated balances and Plasma-Cash-like exit guarantees (originally proposed [here](https://ethresear.ch/t/plasma-debit-arbitrary-denomination-payments-in-plasma-cash/2198/40)). ## Rationale No sidechain solution has been proposed yet which doesn't require a fall-back...
So far we have talked about how to build a NFT with roll_up. Which boils down to basic read and writes. Here i describe how to do efficiently do general...
There are two modes of operation for the merkle tree: 1. Updates in-place 2. Nullify & append The first approach proves the path and preimage of a leaf, then updates...
Improve the cpp code similar to https://github.com/HarryR/ethsnarks/issues/3 and run it on Enterprise hardware. Seems like are limited to 20 million constraints on traditional hardware. See the introduction https://eprint.iacr.org/2018/691.pdf This leaves...
This should reduce the gas required for proving. https://github.com/HarryR/ethsnarks/pull/17
