Starknet Enters Phase 4: Faster, More Decentralized, and Bitcoin-Connected

Starknet is moving into its fourth phase. The goal? A faster, more decentralized, and more private network—with stronger ties to Bitcoin.

Key highlights include the STRK20 framework, which brings ERC20-style privacy features, and strkBTC, an asset redeemable for native bitcoin that offers private transaction options. Starknet v0.15.0 will introduce decentralized block validation, while Staking v3 and v4 will gradually push the network toward full decentralization.

On the Bitcoin front, Starknet is pushing for the OP_CAT upgrade to enable trustless settlement. It's also exploring more Bitcoin bridging solutions—like BitVM and ColliderVM—to help grow Bitcoin DeFi on Starknet. Meanwhile, the S-two verifier will further optimize client-side proof verification, helping scale the network and enhance privacy. Starknet is also working toward full quantum safety, preparing both the blockchain and Bitcoin for the post-quantum era.
