About Bitcoin Layers
Bitcoin Layers is an independent risk research and ratings platform for Bitcoin layer twos and sidechains that maintains a project directory and assesses trust assumptions. It scores BTC custody, data availability, network operators and finality separately on a green, amber and red scale, sorting projects into Bitcoin-native, side-system and alternative-chain categories; ratings reflect trust assumptions only and are not security audits. The pain point is that the industry lumps sidechains, rollups and federated bridges together as layer two, custody and exit paths stay opaque, and investors cannot compare projects side by side.
The platform's output is a public directory updated quarterly, and its data is widely cited by media and funds. On 19 January 2026 it was acquired by Blockspace Media as that group's first proprietary data product, with the original maintainer moving to an advisory role; its 14 January figure had 361,830 BTC, over USD 34.5 billion, locked in layer twos and bridges, and the data product was presented at the OPNEXT event in New York on 16 April.
Bitcoin Layers was acquired by Bitcoin-focused media company Blockspace Media on January 19, 2026, becoming its first proprietary data product. At the time of acquisition, the platform's tracking data showed roughly 361,830 BTC (over $3.45B) locked across Bitcoin L2s, bridges, and scaling solutions, providing unified research and on-chain analytics for the Bitcoin scaling ecosystem.
Following the acquisition, Bitcoin Layers maintainer Janusz stayed on as an advisor, and the data is being integrated into Blockspace's content and an upcoming dashboard that monitors adoption, TVL, and activity across Bitcoin L2s, with plans to distinguish architectural differences such as rollups, sidechains, and federated models.
Bitcoin Layers's Future strategy and roadmap: Blockspace plans to expand coverage to Bitcoin-related equities and ETFs within 2026; the long-term goal is to build a data platform covering the full investable Bitcoin-asset landscape for institutional and retail investors.
Janusz — Founder & Project Lead; physicist and open-source developer who also maintains bitcoinrollups.io, stayed on as advisor after Blockspace acquired the project in 2026.
