2. Spiderchains


FAQs

Q1: What’s the difference between BRC-20 and ARC-20?
A: BRC-20 uses Ordinals’ JSON inscriptions, while ARC-20 leverages Atomicals’ UTXO model with Bitwork mining.

Q2: Is Lightning Network secure?
A: Yes! It uses Bitcoin’s security for off-chain settlements via multisig channels.

Q3: Can Bitcoin support DeFi natively?
A: Not directly, but L2s like BEVM and Stacks enable BTC-backed DeFi via EVM.


Conclusion

2023 laid the groundwork for Bitcoin’s multi-chain future. With protocols diversifying and scaling solutions maturing, BTC’s role as programmable money is just beginning. Whether through Ordinals’ cultural impact or L2s’ technical leaps, the ecosystem echoes the early days of Ethereum’s expansion—ripe for the next "killer app."
