Why Ketju rejected Linea Bridge

Memo v1Published by Ketju Research

A registry memo, published verbatim and versioned. Superseded versions are recorded, never edited away. A rejection is a judgment for Ketju's client base and thesis, not a universal safety claim. Not investment, legal, tax, or compliance advice.

The memo

REJECTED ON GOVERNANCE, NOT ON THE PROOF SYSTEM. Linea is ConsenSys's zkEVM rollup, and its SNARK validity proofs give it a genuine mechanism-level advantage over every optimistic bridge in this registry: withdrawals clear in 2 to 12 hours rather than seven days, because there is no fraud-proof challenge period to wait out. But L2Beat's own structured risk data states contracts are instantly upgradable with a zero-second delay and that there is, in its own words, no window for users to exit in case of an unwanted upgrade — a worse governance rating than every other bridge reviewed in this registry, including the OP Stack chains and the already-rejected Lighter, both of which at least carry some standing delay or forced-exit backstop. Linea also has no sequencer-failure contingency today, and has already demonstrated the risk that combination creates: in June 2024 the Linea team unilaterally halted block production for about an hour during a third-party exploit, a real, not theoretical, exercise of discretionary control over the entire chain.

What would reopen the file

  • A minimum standing delay, even 24 to 72 hours, is introduced between a Security Council upgrade approval and its execution
  • A sequencer-failure or censorship contingency is implemented that does not require the current roughly-six-month proposer-freeze recovery path
  • Security Council signer count and threshold are publicly confirmed and independently verifiable on-chain
  • Twelve consecutive months with no unilateral, discretionary halt of block production by the Linea team or Association
