According to @deanmlittle, a significant improvement in Solana's developer experience (devex) can be achieved by making all system variables (sysvars) globally accessible within the virtual machine (VM) without the need for syscalls. This optimization could reduce the computational cost currently required for copying a sysvar account into a transaction. Such an enhancement would streamline operations and potentially boost the network's efficiency and ease of development.

According to @muneeb, Bitcoin will likely never add privacy at the base layer, placing future privacy features on BTC L2s instead. source: @muneeb He states that if BTC on L2 is fully self-custodial and the L2 offers a full VM, stealth BTC addresses can be implemented at the L2 level. source: @muneeb He adds that information leakage occurs when bridging, but moving from a public L1 address to a stealth L2 address also leaks data, with the design keeping the public address on L1 and the stealth address on L2. source: @muneeb He identifies the core technical hurdle as guaranteeing fully self-custodial L2 BTC so users can always reclaim BTC even if the L2 fails. source: @muneeb He concludes that once fully self-custodial, programmable BTC on L2 exists, a new privacy design space opens, positioning BTC privacy as an L2-driven narrative for traders to track. source: @muneeb
