Why PLANTAURUM runs on Solana
Eco mining produces an enormous number of very small events: a verification here, a yearly reward there, millions of times over. That workload rules out expensive chains immediately. Solana settles in seconds for a fraction of a cent on a proof-of-stake network, which is why the model runs there.
The requirement, before the choice
Start from the workload rather than the brand. Eco mining needs to write a proof and pay a reward for every verified tree, then repeat that every year for every tree that survives. At scale that is millions of tiny transactions.
On a chain where a transaction costs a euro, the fees would exceed the value of the reward and the model would collapse. The chain must make small payments economically trivial, or there is no product.
What Solana provides
- Cost. A standard transfer costs around 0.000005 SOL, a fraction of a cent, so rewarding a single tree is effectively free at the network level.
- Speed. Settlement in seconds, so a verification feels instant to the person holding the phone.
- Energy. Proof of stake, so per-transaction energy is negligible compared with proof-of-work chains. For a project whose entire point is environmental, running on an energy-hungry chain would be indefensible.
- Standards. The SPL token standard and Metaplex metadata are mature and widely supported by wallets and explorers, so PLNT works with tools people already use.
The trade-offs, stated plainly
- Solana has had network incidents in its history. It is not the most conservative chain available.
- Fewer validators than some networks means different decentralisation trade-offs.
- Any chain choice is a bet on an ecosystem, and ecosystems change.
The counterweight is that the alternative, a chain where micro-rewards are uneconomic, does not merely make the project harder, it makes it impossible.
What this means for verification
Because transactions are cheap, proof can be written per tree and per year rather than batched into vague summaries. Granularity is exactly what makes the record auditable, which is the subject of how Proof of Growth works.
