Introduction

The Proof-of-Work algorithm used by VeriBlock (vBlake) was designed to facilitate decentralization at every stage of the natural progression of mining hardware (CPU->GPU->FPGA->ASIC). The simplicity of the vBlake algorithm ensures that single developers or small development teams can produce near-optimal miners for any given hardware class, rather than allowing a single team or company make a massive breakthrough in the implementation and be the sole supplier of competitive miners.

Additionally, the algorithm is small enough to fit onto low-cost consumer grade FPGAs, rather than requiring expensive high-end chips. This allows hobbyist miners to mine VeriBlock in a cost-competitive way with large-scale mining operations. There are also plans to open-source an RTL implementation of vBlake in the near future to allow FPGA developers to easily add vBlake support to more FPGAs.

Pool Software

The built-in pool software included in VeriBlock's NodeCore software has a higher-difficulty setting to accomodate FPGA mining, see: HowTo_run_and_connect_to_PoW_Miner_pool#FPGA_Pools

Available FPGA Miners and Bitstreams

Bitstreams for BCU/VCU1525 cards are available from whitefire as well as from Allmine.

Additionally, the Blackminer F1 and F1-single (and likely F1+) support vBlake, as well as their upcoming entry-level F1 Mini.

FAQ

Is there source code

An FPGA mining core for vBlake (the PoW algorithm for the VeriBlock blockchain):

https://github.com/VeriBlock/vBlake-RTL


Is VeriBlock FPGA resistant?

No.

VeriBlock welcomes the most hashing power to secure the blockchain, and FPGAs are inevitable. Much like we are not "GPU resistant", we are also not "FPGA" resistant.

Appendix

vBlake-RTL release message

Initial vBlake-RTL repo shipped on 5/9/2019, with message on Discord:

**Open-source FPGA mining core for vBlake**

The VeriBlock team is excited to release a free and open-source FPGA mining core for vBlake (the PoW algorithm for the VeriBlock blockchain)!

Github repo: https://github.com/VeriBlock/vBlake-RTL

We designed vBlake to democratize mining at every stage of the mining hardware evolution by being small, straight-forward, and benefitting from existing optimization work already done with BLAKE2b. This approach allows an engineer at any hardware level (CPU, GPU, FPGA, ASIC) to create optimized miners easily, rather than centralizing miner production into the hands of a select few elite engineers/groups who crack the case on significant optimizations.
