- Hashing
- Blake2b - single pipe implementation of blake2b and a pipline-unrolled version for high performance.
- SHA256 and SHA256d
- Packages and interfaces that are shared
- Fifo implementations
- Blocks for parsing/processing streams, as well as testbench files
- Karabutsa multiplier
- Barret reduction for modulo reduction when the modulus does not allow fast reduction
- Resource arbitrators
- General purpose elliptical curve point modules
- Supports point multiplication, addition, doubling in Fp and Fp^2
zcash_fpga
This is the top level for the Zcash FPGA. It targets both Xilinx Virtex UltraScale+ FPGA VCU118 Evaluation Kit, and Amazon EC2 F1 Instances.
It optionally contains the following top-level engines (you can optionally include in a build via parameters):
- Equihash verification engine
- Verifies the equihash solution and difficulty filters
- EC secp256k1 signature verification engine
- Uses efficient endomorphism to reduce key bit size
- Signature verification calculates multiple EC point operations in parallel, using a resource-shared single fully pipelined karabutsa multiplier and quick modulo reduction technique
- EC bls12-381 coprocessor
- Point multiplication in Fp and Fp^2
- ate Pairing
