L2L Sidechain Extravaganza: BitVM, Drivechain & Spiderchain | L2L Spaces | 2023-10-20

October 20, 2023Original source

A LayerTwo Labs Friday Space compares BitVM, Drivechain, and Spiderchain. After tabling Lightning channel-jamming news, speakers explain BitVM as a funded L1 challenge-response, using a chess wager, then a prover and many verifiers for a two-way peg that needs one honest party. Willem Schroe presents Spiderchain as sequential decentralized multisigs over a large staker set, with claimed forward security so a two-thirds takeover can halt the chain without stealing older coins. He walks through Botanix bridge deposits, slashing, and 51% miner risk. Later they cover BitVM verifier deposits, state-transition binary search, liveness versus safety, and atomic swaps in front of a slow peg, then whether proof-of-stake sidechains starve L1 miners. Guests debate a trust-minimized BTC-to-Ethereum peg, Bitcoin versus Ethereum culture, ordinals as fee-paying transactions, and the scaling war. Late questions hit Satoshi Dice, node costs, the one-megabyte cap, and missing features that spawn altcoins. After Robin Linus points listeners to BitVM.org, skipping a Drivechain soft fork is called a symptom of miner-developer distrust. The Space closes on ossification and a coming Botanix testnet.
