There are many expansion plans for Bitcoin, each with its own advantages and disadvantages.

The Lightning network is fast, but the threshold for running nodes is high, making it less user-friendly for ordinary users.
Statechains has innovated in address ownership transfer, but its functionality is relatively singular, making it difficult to meet complex needs.
Custodial and Federated BTC solutions require trust in centralized institutions or alliances, which pose a single point of failure risk.

The @build_on_bob collaborative project on the @cookiedotfun platform cleverly integrates the security of Bitcoin with the programmability of EVM, centered around BitVM and Hybrid Chain.

BitVM adopts an optimistic execution mechanism, placing most of the calculations off-chain and only relying on on-chain arbitration in case of disputes, greatly enhancing efficiency. This innovative technology not only enables low-cost and high-speed Bitcoin transactions but also takes a critical step towards decentralization.

Take a look at the core architecture of #BOB to understand how BOB breaks the trust triangle paradox using the BitVM bridge.

Underlying Security: Merged mining inherits 80% of Bitcoin's hashing power, attack cost = 400 million USD (requires 40% of Bitcoin's hashing power to maintain for 28 hours)

Execution Layer: EVM compatible environment, Gas fees are only 3% of Ethereum L1.

Cross-chain engine: BTC light client verification + BitVM fraud proof, ensuring asset security with just one honest node.

#BOB Hybrid Chain, as the first practical BitVM implementation, is expected to become an important infrastructure in the Bitcoin ecosystem, and its development prospects are worth close attention.
