burn rate in testnet not sustainable

[deantchi]

Describe the bug

Starting version 2.1, a higher than previous burn rate satoshis_per_byte is required to mine blocks. While this is not an urgent matter current, it is not sustainable rate. tBTC is becoming more and more difficult to mine and Hiro has only a finite amount on hand. We don't want to eventually be in a position where we have to spend real money to obtain tBTC from somewhere else. There are at most only 2 testnet miners on the network at any given time and I don't believe there to be any contention.

Steps To Reproduce

The burn rate is currently set to satoshis_per_byte = 20, pre-2.1 was set to only 5. If we reduce it back down, the miner would not mine any blocks.

Expected behavior

I expect the required satoshis_per_byte should be able to mine blocks with the old rate of 5, or even as low as 1.

Not sure this qualifies as a blockchain bug? 🤔 Ultimately block commits have to be included by miners on the Bitcoin testnet. Looking at https://mempool.space/testnet, 1 sat/vbyte should be usually fine.

I think a more robust solution is to explore a signet based testnet instead (something @lgalabru has suggested before too).

options

• running a btc testnet miner
• switch to signet based testnet
