Here we report on the progress of the leading builders in the Bitcoin ZKonomy, documenting recent significant releases, technical breakthroughs and general updates

Citrea

Leading @citrea_xyz researchers - @ekrembal_, @Artsteiin, and Hakan Karakuş - released an article detailing the latest design of Clementine, a BitVM-based Bitcoin bridge. This solution scales Bitcoin’s blockspace using ZKPs while maintaining security and decentralization, introducing an efficient two-way peg mechanism with roles like signers, operators, and watchtowers to ensure trust-minimized BTC transfers. Recent updates enhance efficiency, shorten challenge durations, and improve security: https://review.stanfordblockchain.xyz/p/64-citrea-scaling-bitcoins-future

Goat Network

@GOATRollup unveiled the BitVM2 Playground, offering the first experience with this novel system for natively secure Bitcoin L2 scaling. Utilizing @ProjectZKM zkMIPS proofs, BitVM2 enables secure, decentralized bridge transactions without trusted parties. Its 6-stage architecture ensures verifiable security through challenge mechanisms, economic incentives, and dual slashing: https://goat.network/blog/introducing-bitvm2… You can explore the BitVM2 Playground here: https://bitvm2.goat.network

Meanwhile, GOAT Network has partnered with @Zeepr_labs and @Rhombus_io to expand its DeFi ecosystem. Zeepr brings low-fee trading with synthetic assets, while Rhombus adds a borrow/lend protocol. Both launch in Q1 2025 with GOAT’s alpha mainnet: https://goat.network/blog/goat-network-partners-with-decentralized-perpetual-trading-platform-zeepr

Alpen Labs

@AlpenLabs announced an $8.5M strategic round co-led by @dba_crypto and @cyberFund_ to accelerate the development of @Strata_BTC, a Bitcoin ZK rollup. Strata will enable scalable self-custody, privacy-focused payments, and BTC-backed applications, with public testnet launching soon: https://alpenlabs.io/blog/strategic-round

Strata

@Strata_BTC showcased upgrades to its full node, sequencer, prover, bridge, and BitVM2. Key developments include improved storage, multi-zkVM support, and a trust-minimized bridge. Focused on security and efficiency, Strata aims to enable verifiable, programmable p2p electronic cash worldwide with an EVM-compatible ZK rollup: https://x.com/Strata_BTC/status/1879214064074948817

Nubit

@nubit_org introduced Goldinals, a unified protocol for Bitcoin assets that simplifies and decentralizes asset management. Built with zkOracle and BitVM, Goldinals leverages @SuccinctLabs SP1 for efficient development and powers innovations like Bitcoin-native stablecoins and DeFi, revolutionizing the Bitcoin ecosystem: https://nubit.org/Goldinals.pdf

BitcoinOS

@BTC_OS integrated with @RiscZero’s @boundless_xyz Network, bringing @ethereum-level programmability to Bitcoin. Using zkVM technology for computation verification, it positions Bitcoin as a secure, programmable foundation for decentralized applications, rivaling Ethereum’s dominance in scalability and innovation: https://bitcoinos.build/blog/risc-zeros-boundless-network-brings-ethereum-programmability-to-bitcoin-through-bos…

Additionally, BitcoinOS proposed integrating @Ripple with Bitcoin through BOS, creating a bridge between Bitcoin’s $2 trillion market and Ripple’s advanced financial infrastructure. With Ripple’s expertise in cross-border transactions and XRP Ledger’s speed, this partnership could scale Bitcoin’s utility, connecting traditional and decentralized finance seamlessly: https://x.com/BTC_OS/status/1882438114318373092

LayerEdge

@layeredge teamed up with @fermah_xyz to offer an enhanced ZKP infrastructure for Bitcoin. By combining LayerEdge’s Bitcoin-backed proof aggregation with Fermah’s efficient proof generation marketplace, the partnership delivers scalable, trust-minimized, and cost-effective proofs on Bitcoin: https://x.com/layeredge/status/1881771308213813492…

LayerEdge alse launched its incentivized Testnet, marking a milestone in building the Bitcoin-backed internet. It integrated @RiscZero’s zkVM for efficient off-chain computation, proof aggregation, and rewards users for verifying proofs via light nodes: https://blog.layeredge.io/layeredge-testnet-launch-incentivized-building-the-bitcoin-backed-internet-a7874d2e5cea

Fiamma

@babylonlabs_io has invested in @fiamma_labs to create trust-minimized Bitcoin bridges using BitVM2, enabling seamless integration of Bitcoin with the Babylon chain and Cosmos ecosystem:
