< BTC can also earn premiums? What is the real profit logic behind SatLayer? > One of the core questions of all staking or re-staking logic is whether the income is sustainable. BTC re-staking is no exception. Satlayer's promotion idea is one of the few projects I have seen that is very useful in terms of sustainability and scalability. 1. Highlights of core products: use BTC to run insurance business Satlayer is a BTC re-staking protocol that mainly develops real-world yield scenarios based on Bitcoin Verification Service (BVS). Take the project's core product, the income-based BTC insurance fund, as an example. Familiar with traditional finance, there are no more than three points to measure the ability of insurance companies: capital, risk ability, and cash flow operation ability. SatLayer's approach is to turn BTC into an insurance company's "on-chain reserve": BTC re-staking = insurance pool Forfeiture mechanism = automatic claims system Re-pledge income = simulated premium dividends Reinsurance mechanism = control exposure and spread black swan risk This logic is not simply DeFiization of insurance, but uses Bitcoin to build a new financial structure and participate in the profit distribution of the traditional insurance value chain. The charm of insurance is that as long as there is a risk of loss of assets, its demand has always been rigid. Therefore, under this mechanism, the product can not only serve as liquidation protection for on-chain Babylon/EigenLayer projects, but also meet the tail risk of lending protocols. It can even truly underwrite off-chain real-world insurance (catastrophe, workers' compensation, etc.); In the longer term, it can also expand prime brokerage business, AI Infra verification, stablecoin support, etc. 2. Why Satlayer's earnings are sustainable The benefits here are sustainable for three main reasons: 1\ The premium comes from the real risk transfer demand, not the Ponzi piled up by incentives. 2\BTC is self-sustaining and will not be off-chain, and will only be used if the compensation conditions are triggered, and the funds will be stable. 3\Real scenario expansion + risk manageable and large-scale reuse. I like SatLayer, not because of how many top insurance companies it cooperates with now, nor because of the VC bigwigs like Hack VC and Franklin Templeton standing behind it. Instead, it is under the general trend of rapid integration of the entire industry with real-world assets such as RWAs and stablecoins. The project has given BTC a new role: from a "store of value" to a "risk protection capability". In particular, once an asset like BTC, which is the most trusted, transparent, and difficult to tamper with, can bear the responsibility for real-world risks, the safe-haven nature of BTC is really real. At that time, SatLayer was much more than just "cooperating with several insurance companies", but the core hub of the Bitcoin economic layer.
