Malairte stays mineable on the computer you already own because of a single deliberate design choice: its proof of work is memory-hard. That phrase gets used a lot and explained rarely, so here is what it means and why it matters to anyone running a home rig.

The problem memory hardness solves

If a mining algorithm only needs raw arithmetic, someone can eventually build a chip that does nothing but that arithmetic, extremely fast and cheaply per hash. Those chips, ASICs, then dominate the network and push out everyone with a normal computer. The history of older coins is largely the story of this happening. Memory hardness is the countermeasure.

What memory-hard actually requires

A memory-hard algorithm forces each hash attempt to read from and write to a large amount of fast memory, not just crunch numbers. Speed becomes limited by how quickly the hardware can move data in and out of memory, a quality called memory bandwidth, rather than by pure compute. This reshapes the entire economics of mining.

Why this favours CPUs and GPUs

Ordinary CPUs and GPUs already carry generous, fast memory and wide memory buses, because games and applications need them. They are, almost by accident, well suited to memory-hard work. A specialised chip, by contrast, would have to bolt on large amounts of expensive fast memory to compete, which erases the cost advantage that made ASICs worth building in the first place.

What this means at your desk

  • Your computer memory speed genuinely affects your CPU mining output, which is why faster RAM helps.
  • A consumer GPU stays competitive instead of being made obsolete by industrial hardware.
  • The barrier to joining stays low, which keeps the network spread across many ordinary participants.

The honest trade-offs

Memory-hard designs are not perfect. They are a little less efficient than minimal-memory schemes, and they require ongoing vigilance, because hardware evolves and a future chip might chip away at the assumption. The protocol can be adjusted in response, and that willingness to adapt is part of the bargain.

Why accessibility is the point

None of this promises profit or price. What memory hardness buys is participation. It keeps the door open so that securing the network is something a person with a regular PC can do, not a privilege reserved for those who can afford a warehouse of custom silicon. That open door is the entire reason Malairte chose this path.
