-    A library for constructing storage proofs – including non-circuit proofs, corresponding SNARK circuits, and a method of combining them.

-- [**Storage Proofs Core (`storage-proofs-core`)**](./storage-proofs/core)
+- [**Storage Proofs Core (`storage-proofs-core`)**](./storage-proofs-core)
     A set of common primitives used throughout the other storage-proofs sub-crates, including crypto, merkle tree, hashing and gadget interfaces.

 ## Security Audits
 
-The `rust-fil-proofs` proofs code and the [Filecoin Spec](https://bafybeidxw5vxjdwsun2zc2illagf43v6w5r5w63vg455h7vjesbyqssg64.ipfs.dweb.link/algorithms/sdr/) has undergone a [proofs security audit](audits/Sigma-Prime-Protocol-Labs-Filecoin-Proofs-Security-Review-v2.1.pdf) performed by [Sigma Prime](https://sigmaprime.io/) and been deemed free of *critical* or *major* security issues.  In addition to the security review, the document provides the summary of findings, vulnerability classifications, and recommended resolutions.  All known issues have been resolved to date in both the code and the specification.

 `rust-fil-proofs` has also undergone a [SNARK proofs security audit performed by Dr. Jean-Philippe Aumasson and Antony Vennard](audits/protocolai-audit-20200728.pdf) and been deemed free of *critical* or *major* security issues.  In addition to the security analysis, the document provides the audit goals, methodology, functionality descriptions and finally observations on what could be improved.  All known issues have been resolved to date.
