Putting your idle BTC to work is simple: convert some to YBTC on Bitlayer for lending, market making, and derivatives margin. Fees are lower, confirmations are faster, and application switching is smoother. If you want to exit, you can redeem your BTC back to L1. The most direct benefit is turning "waiting for growth" into "paced cash flow." BTR is the key to this system, connecting execution and fee collection on one end with sorting, staking, and governance on the other, weaving growth and security into a cohesive loop.

From an engineering perspective, Bitlayer is not a sidechain, but a Bitcoin Rollup with "execution on Layer 2 and finality anchored on Layer 1": Contracts execute on Layer 2 using the EVM toolchain, transactions are batched and disputeable, and state commitments are written back to Bitcoin's Proof-of-Work security assumptions. In the event of congestion or censorship, mandatory inclusion and data availability channels ensure "on-chain access and exit" to prevent passive capital retention. Sorting was initially handled by a sequencer, with multi-party rotation and threshold signatures subsequently introduced to reduce single-point-of-stake and censorship risks. Local fee markets and batching strategies smoothed out peak fee spikes, allowing for the implementation of high-frequency strategies.

At the asset level, native BTC is locked in L1 and mapped 1:1 to YBTC for use in L2. The bridge adheres to the principle of minimum trust, with challenge and arbitration procedures written into the protocol, allowing for appeals and forced exits in the event of anomalies. A unified settlement asset reduces the friction caused by multiple bridge hops and repeated packaging, making staking, clearing, and cross-protocol reuse smoother. For market making and clearing networks, more predictable latency and failure rates mean better capital turnover and reduced "black swan" operational risks.

In terms of economic design, BTR plays three roles in one: First, as a payment medium for gas and storage fees, it directly anchors on-chain usage; second, as a staked asset for sorting and relaying, it ties the cost of malicious behavior to penalties, providing a "hard constraint" for security budgets; and third, as a governance token, it participates in parameter tuning, ecosystem funds, and upgrade proposals. Fees and incentives flow back into security and developer subsidies, forming a positive cycle where more usage leads to a stronger network, avoiding the idle cycle of "issuing coins without building." #Bitlayer @BitlayerLabs
