Mintlayer

Mintlayer is a layer 2 sidechain developed to expand the capabilities of the Bitcoin blockchain, enabling decentralized finance (DeFi) functionalities such as smart contracts, tokenization of real-world assets (RWA), and decentralized applications. The project, founded in 2020 by Enrico Rubboli and based in San Marino, aims to bridge Bitcoin's robust security with advanced financial applications. Rubboli, an early Bitcoin adopter and software engineer with prior experience at Bitfinex, envisioned Mintlayer as a way to unlock Bitcoin's vast market for broader financial use cases.

The company's business model revolves around its native ML token, which is used for staking, paying transaction fees, and participating in the network's consensus mechanism. Mintlayer generates revenue through its product studio, Mintlayer Web Services (MWS), which offers blockchain infrastructure and white-label tools for DeFi and RWA management. The platform also provides funding and support to projects building on its ecosystem through initiatives like the Mintlayer Ecosystem Fund. The target clients include developers, financial institutions, and enterprises looking to build on the Bitcoin network.

The core product is a Proof-of-Stake (PoS) blockchain that is anchored to the Bitcoin network for enhanced security. A key feature is its ability to facilitate atomic swaps, which allow for the direct peer-to-peer exchange of native Bitcoin for other tokenized assets on Mintlayer, eliminating the need for wrapped tokens or centralized intermediaries. The protocol uses a UTXO (Unspent Transaction Output) model similar to Bitcoin, which supports parallel transaction processing, and employs non-Turing complete smart contracts to reduce security vulnerabilities. Mintlayer also offers a user-friendly, non-custodial wallet called Mojito and is developing the ZK Thunder Network, a layer 3 solution, to further enhance scalability and support EVM-compatible smart contracts.

The project's journey began with its conceptualization in 2020, followed by a seed funding round of $5.2 million in May 2021. A significant milestone was the mainnet launch on January 29, 2024, which marked the creation of its genesis block and the beginning of its operational phase. Throughout 2024, Mintlayer focused on enhancing its mainnet, releasing the Mojito Wallet, and developing atomic swap capabilities. The company has also secured substantial ecosystem funding to foster development on its platform.
