Blockchain environments may mix-and-match different encryption, difficulty, and/or proof-of-work schemes when mining blockchain transactions. Each encryption, difficulty, and/or proof-of-work scheme may be separate, stand-alone programs, files, or third-party services. Blockchain miners may be agnostic to a particular coin's or network's encryption, difficulty, and/or proof-of-work schemes, thus allowing any blockchain miner to process or mine data in multiple blockchains. GPUs, ASICs, and other specialized processing hardware components may be deterred by forcing cache misses, cache latencies, and processor stalls. Hashing, difficulty, and/or proof-of-work schemes require less programming code, consume less storage space/usage in bytes, and execute faster. Blockchain mining schemes may further randomize byte or memory block access, further improve cryptographic security.

Techniques described herein may be utilised to implement methods and systems for lossless compression and serialisation of arithmetic circuits to a bit stream using compression techniques such as the arithmetic coding. An arithmetic circuit representing a smart contract may be compressed using arithmetic coding, thereby generating a compressed arithmetic circuit that can be stored or broadcast to a blockchain network using less computational resources (e.g., data storage resources) than would otherwise be needed to store the arithmetic circuit. The arithmetic circuit can be efficiently compressed using entropy coding based on the frequency of elements in the data structure, such as the arithmetic operator types. Instructions for de-serialisation and de-compression can also be embedded in the bit stream, and can be used (e.g., by another computer system) to reconstruct the original circuit in a lossless manner.
