1. Amendment for Subcoin milestone3 …

   In light of recent developments, it has become evident that fully syncing
   to the tip of the Bitcoin network and enabling new nodes to perform fast
   sync to the latest Bitcoin state is more challenging than initially anticipated,
   caused by the huge state of UTXO set (over 12GiB). As a result, I propose
   adjusting the delivery goal for this milestone.
   
   The most significant known blocker is paritytech/polkadot-sdk#4.
   Other underlying issues may also contribute to the difficulty. Recent experiments
   have shown that fast sync from around block height 580,000 is currently infeasible,
   succeeding only on machines with 128GiB of memory (paritytech/polkadot-sdk#5053 (comment)),
   which is impractical for most users. Nevertheless, we have successfully demonstrated that
   decentralized fast sync is possible within a prototype implementation.
   
   While syncing to the Bitcoin network's tip remains a future target, addressing
   the existing technical challenges will require substantial R&D efforts.
   We remain committed to exploring potential solutions, including architectural
   changes and contributing to resolving issue paritytech/polkadot-sdk#4,
