I think this points needs more elaboration. It’s not just about better UX but reducing overhead at exchanges/wallets. If sBTC is not directly accepted by miners then the exchanges need to work on the complexity of acquiring/managing STX to use as fee (even for sponsored transactions). Anything that increases complexity makes integration a uphill battle vs saying “just use sBTC for fee directly”.
To be the best Bitcoin L2, I’d encourage taking a product first lens. What is the right product to ship? There are < 1M unique STX addresses and 50M unique BTC addresses (18M monthly active BTC addresses). If you enable these 10s of millions of BTC holders to permissionlessly use Stacks L2 (without acquiring any other asset) then that is huge win for Stacks.
BTC as gas is also a real differentiator for Stacks in the market. How many other networks do this? Would Solana ever do it? Would Ethereum? No. It signals the Bitcoin alignment to the world. It says that this project is being built by people who want to create a BTC economy and enable as much use of BTC as possible. STX will continue to have it’s unique use: things that BTC absolutely cannot do. Those are two things:
(a) STX as coinbase incentive for miners/sequencers. BTC can never do this because you can’t print BTC out of thin air. Only a separate asset like STX can serve this need for miner/sequencer incentives for coinbase (newly minted) rewards.
(b) STX as locked capital to participate in signing sBTC peg. BTC can never be used for this purpose because this locked capital is needed to bring BTC to L2 in the first place.
(c) STX for voting on SIP process. Only people who have “skin in the game” for this project should be able to vote and only STX serves that purpose.
For gas payments, as we’ve discussed, both STX and BTC can serve that purpose. And it’s largely functionally equivalent. Miners need to sell (at some cadence) to cover their costs and they’ll sell whatever asset they received and then keep their preferred asset (say USDC) on their books for on-going capital needs.
Zooming out a bit: building the right product, building a system that instinctively feels like a Bitcoin L2 to new users is extremely important. Having a product that can easily be integrated by exchanges/wallets all over the world is important. These things will determine the success/failure of the project more than other factors, in my opinion.
I see this point. I have a different view here. Stacks Nakamoto is a radically new system. It’s the biggest thing this project has ever done (even bigger than the original mainnet launch in 2021). What is critical here is to ship the right product for the market. I look at it as the opportunity to upgrade as many things as possible based on lessons learned over the last 2 years, and upgrade them all in one go. So on day 1, the new users that are coming can have an amazing first experience!
