Still don't know how it is, tge seems to issue over 1000, should be around 100u, just my guess, currently can't understand the coin price, but this community is quite impressive, the previous presale price was around 0.2🤔

Bitlayer is a Layer 2 aimed at Bitcoin, featuring a combination of BitVM + Rollup: submitting state commitments and dispute resolution on L1 (Bitcoin), providing a real-time programmable environment (Real-time EVM) on L2, aiming to anchor security as much as possible on Bitcoin consensus while giving developers a familiar contract stack. Official materials define it as 'Bitcoin Rollup powered by BitVM stack & Real-time EVM', and the technical white paper clearly outlines the 'State Claim → challenge → adjudication' process. In simple terms, the direction is: the security of BTC remains unchanged, while expansion and programmability are handed over to L2.

Core components (sufficient version)

1) BitVM Bridge: Bringing native BTC to L2 as a 1:1 accounting asset, supporting a trust-minimized process that can be questioned and redeemed; after the mainnet of the bridge goes live, the accompanying yBTC (1:1 pegged to BTC) becomes a universal certificate for entering and exiting DeFi. The key feature is 'malicious actors can be caught', rather than completely entrusting custody to a centralized party.

2) Real-time EVM: The execution environment and toolchain are basically aligned with the Ethereum ecosystem, directly indicated on GitHub to be based on a geth branch, facilitating migration and expansion; for high-frequency scenarios like DEX, lending, and derivatives, EVM can be run first, and then gradually anchor security back to Bitcoin.

3) Rollup/State Claim: Write L2 results back to Bitcoin in batches, inheriting L1 security through the 'state claim + dispute period' process; the white paper and documentation emphasize this point, which is the key to 'not being a sidechain'.

How developers can get started (three steps are enough)

Step 1: Determine the funding entry point - bridge into yBTC or bridge multi-chain assets to Bitlayer; Step 2: Deploy contracts according to EVM conventions (Solidity/Hardhat/Foundry can be used), first ensure the reading, writing, and event routing are functional; Step 3: Integrate L1 related 'state commitments/dispute period' parameters into your risk control logic (settlement buffer, withdrawal window, oracle fallback), avoiding treating L2 as 'instant finality'. By doing this, you can get a familiar development experience while avoiding small pitfalls of cross-domain settlement.

How users can use BTC (no detours, just say it directly)

The entry point is BitVM Bridge → yBTC. Locking BTC according to the official process, after obtaining yBTC, you can participate in DEX liquidity, lending, or other DeFi applications on Bitlayer; when you need to exit, follow the bridge's redemption process to exchange back for native BTC. Unlike traditional 'custodial bridges', this emphasizes questioning and adjudication mechanisms, reducing 'single point of trust'. Suitable for users who do not want to sell BTC but want to take a turn in DeFi.

Differences from other BTC L2s (engineering perspective)

Bitlayer combines 'security anchor + programmability + asset bridge' into a single link: security relies on BitVM's interactive proof and L1's challenge; programmability relies on EVM to quickly accommodate the existing ecosystem; the asset layer uses yBTC as a standard entry point, avoiding the fragmentation of liquidity caused by various semi-custodial receipts. External reports and community documents repeatedly emphasize the route of 'BitVM implementation + Bitcoin Rollup', which determines that it is more like an 'expansion layer under Bitcoin's security assumptions', rather than a pure EVM sidechain.

5 operational signals you should watch (definitely need to monitor!!!)

1) The reliability of the bridge's redemption and the timeliness of dispute resolution (the foundation of the deposit and withdrawal experience). 2) The liquidity of yBTC and scenario coverage (whether DEX, lending, and derivatives keep up). 3) The decentralization progress of sequencers and proof services (whether there is still a single point or custodial components). 4) Settlement costs and batch parameters (batch size, fee/delay trade-offs). 5) The speed of migration in the EVM ecosystem (whether leading protocols and toolchains are in place). These can either be found in the official white paper/documentation or in public reports and browser panels.

BitVM is still iterating, and dispute games require 'honest participants online'; cross-domain settlement means there is a time window for withdrawals; applications on the EVM side still face regular contract risks. For developers, it is crucial to write the challenge period, withdrawal delays, and fallback paths into product documentation and reflect them in the UI; for users, it is essential to understand the bridge's redemption rules and waiting times before deciding on position sizes.

The value of Bitlayer lies in 'turning BitVM into a usable engineering stack': bridging into yBTC, running applications on EVM, and anchoring state commitments back to Bitcoin. What you are looking for is 'can we really bring BTC into the programmable world and still return home decently', and this link provides a sufficiently clear answer.
