We pair business fundamentals with crypto native perspective to back innovators at the earliest stages.
Portal Venture's Catrina Wang with a piece of their thesis about the Bitcoin ecosystem moving forward.
The Bitcoin ecosystem has evolved significantly since the publication of their original "Panda Renaissance" thesis in 2023, with increased market interest and capital investment. Observations include fierce competition among EVM L2s/side chains, intensified fragmentation, skepticism of side chains' aspirations for BitVM, and a wide array of trust assumptions across L2 and metaprotocols. Despite ongoing skepticism, the belief remains that there is value in the Bitcoin vertical.
Predictions for the future of the Bitcoin ecosystem include 1-2 winners per approach, a flight to safety, the majority of other Layer 2 solutions not surviving, developers awakening from the BitVM dream, BTC DeFi surpassing ETH's, and the emergence of Bitcoin's native "ERC-20" token standard.
Exciting whitespace verticals include the bridge-less experience, unifying infrastructure, exports of BTC liquidity into other L1s, a winner in stablecoin, OP_CAT, a native Ordinals trading platform, alternatives to BitVM, on-chain BTC-on-BTC yield products for institutions, and liquid staking on bitcoin.

An article about DLCs, co-authored by ScaleBit, DLC.Link, and Bison Labs.
Discreet Log Contracts (DLCs) are gaining attention as potential solutions for Bitcoin lending, cross-chain transactions, and custom contracts. However, they should be viewed as agreements with predictable outcomes, not as complex smart contracts.
DLCs are being used in cross-chain asset management, with projects like DLC.Link and Bison Lab aiming to create superior cross-chain value transfer methods. Despite their potential, there are security concerns, including the reliability of oracles, the introduction of hash time locks, and the on-chain/off-chain deployment issue.
While DLCs offer unique advantages, their security has not been extensively tested, and potential risks should not be overlooked.

A two-parts article from BTCEden that gives a low-down on the specific BitVM-inspired implementations from Citrea and Bitlayer.
Both Bitlayer and Citrea utilize the BitVM2 solution, which operates on a "pay-and-reimburse" model and has no security issues but faces liveness/availability problems. The BitVM bridge adopts a channel-like approach, allowing users to "verify by yourself" by using pre-signatures to prevent the BitVM bridge from manipulating the deposit pool without authorization.
The BitLayer team has additionally introduced a cross-chain bridge solution called OP-DLC to address the liveness issues of the BitVM bridge and provide a clean and independent channel for individuals with specific needs.
Paper on new bitcoin layer 1 design. Contribute to LNP-BP/layer1 development by creating an account on GitHub.
Maxim Orlovsky from LNP/BP Standards Association has proposed a new design to scale and anonymize Bitcoin directly at Layer 1 with client-side validation.
The proposed system, codenamed Prime, is a blockchain-type ledger offering improved scalability and privacy. It consists of four main components: a timestamping service, proofs, a single-use-seal protocol, and a smart contract protocol. The timestamping service generates headers committing to external client-side-validated data. Proofs are public data published by miners. The single-use-seal protocol prevents double-spending attacks, and the smart contract protocol provides programmability and rich state. The system can be deployed independently from the Bitcoin timechain, with its consensus anchored to Bitcoin PoW security. It can also be launched with miner-activated non-fork or a Bitcoin soft-fork. Upgrades to the system are possible through fast-forward changes or push-backs.

An article from Taproot Wizard's Eric Wall which discusses the implications of the OP_CAT opcode in Bitcoin.
OP_CAT, upon successful reactivation, will allows for the creation of covenants and the verification of Merkle branches. This could lead to the development of Layer 2 solutions similar to Plasma or Optimistic Rollups.
The author also explores how the introduction of OP_CAT could impact Miner Extractable Value (MEV) and the centralization of block production. It concludes that expressive economic activity can be secured by Bitcoin without drastic MEV consequences as long as the environment is safely sequenced by non-miners, which OP_CAT enables.
