# RandomX
|
||||
RandomX is a proof-of-work (PoW) algorithm that is optimized for general-purpose CPUs. RandomX uses random code execution (hence the name) together with several memory-hard techniques to achieve the following goals:

|

|
||||
The VM executes programs in a special instruction set, which was designed in such way that any random 8-byte word is a valid instruction and any sequence of valid instructions is a valid program. For more details see [RandomX ISA documentation](doc/isa.md). Because there are no "syntax" rules, generating a random program is as easy as filling the program buffer with random data. A RandomX program consists of 256 instructions. See [program.inc](src/program.inc) as an example of a RandomX program translated into x86-64 assembly.

#### Hash calculation
|
||||
### Hash calculation
|
||||
|
||||
Calculating a RandomX hash consists of initializing the 2 MiB scratchpad with random data, executing 8 RandomX loops and calculating a hash of the scratchpad.

The loads from the dataset are fully prefetched, so they don't slow down the loop.

RandomX uses the [Blake2b](https://en.wikipedia.org/wiki/BLAKE_%28hash_function%29#BLAKE2) cryptographic hash function. Special hashing functions based on [AES](https://en.wikipedia.org/wiki/Advanced_Encryption_Standard) encryption are used to initialize and hash the scratchpad.
|

RandomX uses the [Blake2b](https://en.wikipedia.org/wiki/BLAKE_%28hash_function%29#BLAKE2) cryptographic hash function. Special hashing functions `fillAes1Rx4` and `hashAes1Rx4` based on [AES](https://en.wikipedia.org/wiki/Advanced_Encryption_Standard) encryption are used to initialize and hash the scratchpad ([hashAes1Rx4.cpp](src/hashAes1Rx4.cpp)).
|
||||
|
||||
#### Hash verification
|
||||
### Hash verification
|
||||
|
||||
RandomX is a symmetric PoW algorithm, so the verifying party has to repeat the same steps as when a hash is calculated.
|
||||
|
||||
However, to allow hash verification on devices that cannot store the whole 4 GiB dataset, RandomX allows a time-memory tradeoff by using just 256 MiB of memory at the cost of 16 times more random memory accesses. See [Dataset initialization](doc/dataset.md) for more details.

### Performance
|
||||
Preliminary mining performance with the x86-64 JIT compiled VM:
|
||||
|
||||
|CPU|RAM|threads|hashrate [H/s]|comment|
|
||||
|-----|-----|----|----------|-----|
|
||||
|AMD Ryzen 1700|DDR4-2933|8|4100|
|
||||
|Intel i5-3230M|DDR3-1333|1|280|without large pages
|
||||
|Intel i7-8550U|DDR4-2400|4|1200|limited by thermals
|
||||
|Intel i5-2500K|DDR3-1333|3|1350|
|
||||
|
||||
Hash verification is performed using the portable interpreter in "light-client mode" and takes 30-70 ms depending on RAM latency and CPU clock speed. Hash verification in "mining mode" takes 2-4 ms.
