Why BIP-361 Can’t Rescue Satoshi’s Bitcoin, According to Charles Hoskinson
Cardano (ADA) founder Charles Hoskinson argues BIP-361’s zero-knowledge restoration mechanism can’t rescue roughly 1.7 million Bitcoin (BTC) locked in pre-2013 addresses. This consists of roughly 1.1 million Bitcoins attributed to Satoshi Nakamoto.
Casa co-founder Jameson Lopp and 5 co-authors submitted the Bitcoin Improvement Proposal (BIP-361). It seeks to sundown legacy ECDSA/Schnorr signatures, rendering funds on these addresses unspendable.
Hoskinson Flags Fatal Gap in Bitcoin’s Quantum Plan
Estimates point out that over 34% of Bitcoin is held in addresses potentially weak to future quantum threats, prompting renewed concentrate on mitigation efforts. The BIP-361 proposal seeks to handle the vulnerability.
The draft phases out legacy Bitcoin signatures in three levels. Phase A blocks new sends to weak addresses. In Phase B, nodes would reject all transactions that depend on ECDSA and Schnorr signatures
Phase C, pending additional analysis, would let holders get well frozen cash. They would submit a zero-knowledge proof of possession of a BIP-39 seed phrase. However, issues stay over the feasibility of such restoration. In a latest video, Hoskinson acknowledged that,
“1.7 million cash can’t do this. It’s not attainable. 1.1 million of which belong to Satoshi.”

He explained that these coins originate from Bitcoin’s early structure, which predates trendy requirements like BIP-39 seed phrases and hierarchical deterministic key technology.
As a end result, they fall exterior the assumptions required for zero-knowledge-based restoration techniques, limiting the effectiveness of proposals like BIP-361 for older holdings.
“should you construct a ZK system primarily based upon proof of a press release, your bit 39 key, say I’ve these items, you possibly can get well a few of the 8 million Bitcoin, however 1.7 million are on not beneath this scheme. All of the 2013 Bitcoin and earlier than,” he added.
The limitation is acknowledged in BIP-361 itself, which concedes it’s “not attainable to assemble a proof of HD pockets possession for UTXOs created earlier than BIP-32 existed.”
“Phase C can also be appropriate with an ‘Hourglass’ model BIP for spending P2PK encumbered funds, offered such a BIP has activated by the point Phase C prompts,” the draft reads.
Hoskinson additionally disputes the soft-fork classification. He says the plan would require a onerous fork. The BIP-361 textual content acknowledges that consensus guidelines might ultimately want to loosen.
“After Phase B, each senders and receivers would require upgraded wallets. Phase C, if activated along with Phase B, could also be tender forkable, in any other case it might probably require a loosening of consensus guidelines (a tough fork) to enable weak funds to be recovered,” the authors wrote.
Notably, Lopp acknowledged the discomfort with the proposal, stating that he doesn’t prefer it himself however considers the choice even much less acceptable.
