ChainCatcher news, according to The Block, the Bitcoin Virtual Machine (BVM) team launched the BitZK service last week, which is a solution based on zero-knowledge proofs (ZK proofs) aimed at enhancing Bitcoin's scalability. The BitZK service allows users to create rollups and migrate applications from the Ethereum network to the Bitcoin network.Currently, BVM charges at least $99 per month for its BitZK service and has attracted a group of early users, including Bitcoin Layer 2 projects RWA Chain, POWD3R Blockchain, and Octopus Bridge.

ChainCatcher message, the developer of the decentralized social protocol Nostr, fiatjaf, stated in a blog post that he suggests using Spacechains and Fedimint (a Bitcoin custodial open-source protocol) to address the Bitcoin scalability issue. According to fiatjaf's proposal, the following can be done without attempting to create complex "layer 2" setups involving new cryptographic technologies:Adopt the Fedimint source code and remove the "mint" feature, only using their secure Token with multisig and federation features;Then create a Spacechains;Allow the federation to issue multisig-btc Tokens on Spacechains;Set up facilities similar to Uniswap on it, allowing these Tokens to be freely traded.fiatjaf explained the reason for proposing this idea: "The recent surge in fees caused by Ordinals and BRC-20 Tokens indicates that the Lightning Network is not a panacea. The channels are too fragile, and the costs of opening channels and running routing nodes in a high-fee environment are very high. Those who want to continue using the Lightning Network are turning to large Lightning Network custodial providers: WalletofSatoshi, ZEBEDEE, OpenNode, and so on. We can leverage people's trust in these companies (and individuals) operating Lightning Network providers, turning each of them into a Bitcoin token issuer. Each company issues its own Token, and trading flows freely. Everyone can only hold assets from the issuers they trust more." (source link)
