The actual structure where liquidity staking and data availability are combined in Bitcoin native assets @Lombard_Finance , @nubit_org , @MezoNetwork This article explains how Bitcoin native assets are utilized and verified through liquidity staking and data availability layers. Bitcoin has traditionally been used as a means of payment and a store of value, and recently, cases have emerged where it is used as collateral for external systems and a security benchmark. In this trend, liquidity staking derivatives based on Bitcoin and data availability technologies to verify the status of these assets are being used in parallel. A representative example of Bitcoin liquidity staking is Lombard's LBTC. LBTC is a token issued after depositing Bitcoin on a 1:1 basis, and the deposited Bitcoin is used to provide security for external proof-of-stake networks through the Babylon Bitcoin staking protocol. The security fees generated in this process become the source of revenue, and no changes to the Bitcoin protocol itself are required. Lombard manages assets through a security consortium involving multiple global institutions and publicly discloses Bitcoin holdings through a proof of reserves method. This structure provides institutional-level custodial stability but relies on trust in the consortium's operations and decision-making. As liquidity staking assets expand, the issue of verifying whether these assets are actually deposited and locked becomes crucial. At this point, the role of Nubit, a data availability layer, comes into play. Nubit uses a BitVM structure designed to verify off-chain computation results on Bitcoin. This allows for complex state changes and calculations to be verified by Bitcoin consensus even if they are not directly recorded on the Bitcoin main chain. The key concept presented by Nubit is a proof method that cryptographically verifies the total amount and state of deposited Bitcoin, which is used to confirm whether the liquidity staking assets match the actual collateral. Verification based on BitVM secures finality based on Bitcoin block confirmations, and typically, the state is finalized after several block confirmations. This has processing delays compared to other smart contract platforms but retains the security based on Bitcoin's proof-of-work hash power. Nubit claims high throughput by logically separating and parallelizing data availability processing, but these figures are presented based on structural design explanations. Alongside this, there is Mezo as an execution layer case based on Bitcoin. Mezo designs network participation and reward structures by locking Bitcoin and Bitcoin derivatives, moving Bitcoin into the execution environment through a bridge utilizing multi-signature and threshold cryptography techniques. Consensus and execution within Mezo occur in a separate high-speed consensus engine, with final settlement relying on Bitcoin. The stable assets used within Mezo are maintained by Bitcoin collateral, and currently, Lombard's liquidity staking tokens are not used as collateral in this structure. In summary, liquidity staking provides a means to utilize Bitcoin as a security resource for external networks, while the data availability layer verifies the asset status and collateral in this process based on Bitcoin standards. The combination of Lombard and Nubit shows a structure that can verify the quantity and lock status of deposited Bitcoin without relying on external trust reports. However, each layer adopts different trust models and operational methods, and the overall structure, including the execution layer, exists in parallel. As a result, the combination of liquidity staking and data availability of Bitcoin native assets provides a concrete technical case where Bitcoin is used as collateral and a verification standard. This structure allows for the separation of asset management and state verification based on Bitcoin's security, clearly revealing the roles and limitations of each layer. This reflects the current technological status showing that Bitcoin is being used as a benchmark asset across various systems beyond a single-function asset. $BARD $LBTC $MEZO
