The only downside of a miner running on phones is the battery life, but as you said that it will only consume around 1-2% per day then this can be a way forward in achieving true decentralization.
A fast blockchain with over 300k TPS requires a large number of blocks and the software on the phone must be constantly active and consume enough resources. It is impossible to achieve such speeds in mining coins, so this coin does not have mining, but possibly nodes on mobile phones. But I don’t know where such speed comes from on weak mobile devices.
Yeah good questions. That throughput is achieved through a number of reasons:
- sharding (parallel TX processing)
- layering (group TX processing)
- zero knowledge proofs
- RSA accumulators to store/query/update chain
The actual data load is minimal and the calculation process can be completed in milliseconds by smartphones without any visible reduction in battery life. Blocks are formed, verified and generated every 8 seconds.
Zero-knowledge proofs require even more resources, and the more shards in the blockchain, the more calculations. I am a miner, I can be wrong, but I think that this is a logical opinion. Then where do the main calculations take place if the mobile nodes do not consume resources?
Do they validate blocks without validation?
In the chain WP, we have a few sections that shed light on this. 10. Implementation (under Transaction Performance), 6. Structure (How miners produce blocks and Transaction Processing).
Mobile nodes mainly play the role of verifying and generating blocks?with proposer nodes performing the calculations required to form blocks.
Besides the algorithm and network structure, the other part is the data load. Most blockchains that use Trie or Merkle Trees have a heavy data load, where 10 state changes can lead to a 200x data load. That means a 300GB ledger taking up 15TB. We've reduced that to just 1 gigabyte of storage, partly through using RSA accumulators.
