Sucash / Suchain.

Sucash is based on double structured cryptography which results in strong anonimity, swift transactions and a lightweight network (suchain). To achieve this, I will be using zk-SNARKs, partly based on the Zcash protocol for anonymity and what I will now refer to as proof-of-reference to maintain a secure ledger. Result: Strong anonymity whilst keeping the transaction network small, fast and lightweight.

After multiple phases of testing the Zcash protocol I believe it is one of the strongest forms of anonymity. Reason for this is because Zcash uses zK-SNARKs (zero knowledge proofs) to avoid disclosing the parties and funds involved. Proof systems like these are reminiscent of cryptosystems with perfect secrecy. Sucash can be shifted into different phases (private/protected), locking it into a bucket, removing its transaction history. The buckets are encrypted and can be exchanged with one another.

I’ve taken the Zcash protocol and had to remove some essential parts for the viewkeys in order to combine and implement the proof-of-reference structure i’ve been working on for the last year. This structure carries a proof-of-work and ‘reference’ of multiple previous transactions allowing each transaction to confirm the other creating a Direct Acyclic Graph (DAG) of transactions (suchain). There are no blocks within the suchain and each transaction carries it’s own proof-of-work creating a slim and swift payment network while keeping satoshi’s core principles of decentralisation, privacy and unforgeability.

For the next month I will be focusing on the code and whitepaper. Not sure about when/how to release yet, as I care for fair distribution.

I definitely love doing this, and enjoy meeting like-minded people. I'd like this to become a project that breaths the open-source spirit bitcoin once started with and so I appreciate any help.
