From October 20 to 22 by the banks of Shanghai's Huangpu River, the 2026 Sustainable Global Leaders Conference returns once again. Nobel laureates and Turing Award winners will present on-site discussions about the future and trends of technology, and the internet-famous professor who "rescues" people from anxiety and the rat race era — Macfarlane and Xiang Biao — will engage in a live dialogue!
Limited spots available, first come first served. Let us journey together toward the sustainable appointment! [Click to register] Nasdaq-listed cryptocurrency exchange Coinbase Global, Inc. (NASDAQ: COIN) published a blog post recommending that Bitcoin should begin preparing for quantum computing threats now rather than waiting for the risk to arrive.
The exchange, which holds approximately 5% of the world's current Bitcoin on behalf of clients including banks, asset management firms, and hedge funds, pointed out that Bitcoin's response to the quantum threat requires flexible addresses, backup quantum-protected keys, and separate handling of the lost coin problem.
The blog post explained Bitcoin's lock-and-key mechanism: a Bitcoin wallet is like a mailbox with a narrow delivery slot — the public key is the delivery slot that anyone can drop into, and the private key is the physical key held only by the owner. When a user sends Bitcoin, the wallet uses the private key to create a digital signature, and the network verifies it through the public key — if they match, the transaction is approved.
The Bitcoin blockchain uses two methods, ECDSA and Schnorr, to create and verify digital signatures. Current computers cannot crack their mathematical principles or reverse-engineer the private key from the signature or public key. According to Google researchers, sufficiently powerful quantum computers may emerge by 2029, capable of reverse-deriving the private key from the public key and emptying holders' wallets. Researchers call machines with this capability cryptographically relevant quantum computers (CRQCs).
The proposed solution is post-quantum cryptography — new signature methods capable of withstanding quantum attacks. Coinbase Global, Inc. (NASDAQ: COIN) believes that simply choosing new security methods is not enough. It argues that a complete upgrade to protect Bitcoin from quantum computer attacks must simultaneously protect old funds and new funds, adapt to Bitcoin's limited data space, allow ordinary computers to continue running the network, apply to large crypto platforms and ordinary users alike, and provide a clear plan for old coins that may never move.
