RSK Labs was founded in 2015 by Diego Gutiérrez Zaldívar (CEO & Co-Founder) and Ruben Altman (Co-founder).
RSK Labs has raised $5.0M in total across 2 funding rounds.
RSK Labs operates Rootstock, an open-source smart contract platform atop the Bitcoin network. It enables deployment of EVM compatible smart contracts, secured by Bitcoin's proof-of-work mechanism via a two-way peg. This extends Bitcoin's utility, providing programmable capabilities and interoperability for decentralized applications. The platform allows developers to build and run decentralized solutions with the security assurances of the Bitcoin blockchain.
Founded in 2015 by Diego Gutiérrez Zaldívar, Sergio Lerner, Ruben Altman, Adrian Eidelman, and Gabriel Kurman, RSK Labs emerged from the insight that Bitcoin's unparalleled security could underpin a versatile smart contract layer. These technologists sought to unlock Bitcoin's potential for advanced applications, integrating programmable logic without altering its core. Their collective experience drove the development of this foundational blockchain technology.
Rootstock serves developers creating decentralized applications and financial services leveraging Bitcoin's security. RSK Labs aims to foster Bitcoin-secured finance, facilitating lending, borrowing, and cross-border payments. Its vision is to cultivate an inclusive financial ecosystem powered by the world’s most secure blockchain, enabling broad financial access and innovation through its robust infrastructure.

RSK Labs, now operating as IOV Labs and closely tied to RootstockLabs, is a blockchain technology company founded in 2015 that develops smart contract platforms secured by Bitcoin's network.[1][2][5] It builds the RSK (Rootstock) platform, a Bitcoin sidechain enabling Turing-complete smart contracts, decentralized applications (DApps), DeFi, payments, data storage, identity, and more via its RSK Infrastructure Framework (RIF) and RIF OS ecosystem.[1][2][4][5] Serving developers, businesses, and innovators seeking Bitcoin's security without its limitations, RSK solves Bitcoin's lack of programmability by offering Ethereum-like features (e.g., Solidity support) through merged mining with over 50% of Bitcoin miners, faster blocks (15-30 seconds), and scalable infrastructure for a global financial ecosystem.[1][2][3][4] Growth momentum includes 100% uptime since 2018 launch, pioneering Bitcoin DeFi, and ongoing expansions like RIF incentives for interoperability.[5]
RSK Labs was founded in 2015 by Diego Gutiérrez Zaldívar (CEO and co-founder), with headquarters in Gibraltar, Spain, as a joint venture involving Monday Capital.[1] The idea emerged from recognizing Bitcoin's security and value store potential but its limitations in smart contracts and scalability, leading to RSK as the first Bitcoin sidechain with two-way pegging, merge-mining via SHA-256, and Proof-of-Work validation.[2][4][5] Early traction came from open-sourcing software, firmware, and hardware; securing miner support (over 50%); and launching the RSK Smart Contract Network, which evolved into RIF protocols and RIF OS for broader decentralized services.[1][2] Pivotal moments include the 2018 Rootstock mainnet launch with perfect uptime and RootstockLabs' formation around 2017-2018 to extend Bitcoin functionality.[5]
RSK Labs rides the Bitcoin DeFi and scaling trend, extending Bitcoin's $1T+ market cap into programmable money amid rising demand for secure, decentralized finance post-Ethereum congestion and layer-2 booms.[2][5] Timing aligns with Bitcoin's maturation as a settlement layer, where sidechains like RSK unlock DeFi, NFTs, and real-world apps (e.g., supply chains, governments) without compromising its security model.[1][4] Market forces favoring it include miner incentives for merge-mining, regulatory clarity for Bitcoin-native solutions, and interoperability needs via RIF bridges.[1][5] It influences the ecosystem by pioneering sidechains, inspiring drivechains, and boosting Bitcoin utilization—turning it from store-of-value to global financial infrastructure.[2][5]
RSK Labs is poised to accelerate as Bitcoin DeFi explodes, with RIF tokens driving adoption through incentives and Rootstock scaling to "civilization scale" via faster tools and inter-chain bridges.[5] Trends like Ordinals, Runes, and institutional Bitcoin inflows will amplify its momentum, potentially capturing Ethereum-like TVL on Bitcoin's base. Its influence may evolve from pioneer to standard-setter, powering enterprise DApps and embedding Bitcoin in everyday finance—solidifying its role in a new global ecosystem that started with a bold sidechain vision.[1][2][5]
