Could quantum computing threaten Satoshi Nakamoto’s 1 million Bitcoin?

As a researcher with years of experience delving into the complexities of blockchain technology and its applications, I find myself constantly intrigued by the ongoing debate surrounding Satoshi Nakamoto’s 1 million BTC. The potential threats posed by advancements in quantum computing to the earliest transaction format of Bitcoin have indeed sparked a lively discussion within the crypto community.

Discussions about the safety of Bitcoin’s initial transaction structures have sparked renewed arguments regarding what might happen to Satoshi Nakamoto’s 1 million Bitcoins, given that advancements in quantum computing could potentially endanger the digital currency.

Is it reasonable for the original issuer of Bitcoin (BTC) to have their 1 million coins locked away to prevent potential misuse, a topic being discussed by some within the cryptocurrency community given the rapid advancements in quantum computing?

The concern arises due to the vulnerability of Bitcoin’s earliest transaction format, pay-to-public-key (P2PK), which exposes public keys on the blockchain.

Unlike current Pay-to-Public-Key-Hash (P2PKH) transactions’ outputs, early P2PK transactions may be vulnerable to attacks by quantum computers that can compute private keys from public keys, as suggested by Ethan (Emir) Sierer, the founder and CEO of Ava Labs.

From my perspective as an analyst, while some individuals view the freezing of Satoshi’s coins as a prudent measure to prevent potential risks, others express concerns that such action might contradict Bitcoin’s core principles of decentralization and immutability. Nevertheless, it is crucial to acknowledge that Satoshi’s vast hoard of 1 million BTC serves as an attractive high-value target for quantum attackers. Such attacks could potentially disrupt the market significantly.

Are the coins vulnerable?

The original Bitcoin created by Satoshi Nakamoto can be found in the initial Pay-to-Public-Key (P2PK) output transactions. This transaction format is not widely used anymore as it reveals the user’s public key, exposing their identity.

Due to the advent of P2PKH, a method that conceals the public key within a hash until funds are expended, the task of hacking with quantum computers has grown markedly more intricate compared to attacking an exposed public key.

The current resilience of P2PK outputs against quantum threats may seem insignificant, but as progress continues in quantum computation and quantum hacks become feasible for cybercriminals, this could become a potential concern in the future.

Freezing Satoshi’s 1 million BTC

Freezing Satoshi’s Bitcoins would necessitate modifying Bitcoin’s agreement principles to designate certain unspent transaction outputs (UTXOs) as unusable.

To implement this procedure, developers must first prepare a Bitcoin Improvement Proposal (BIP) outlining the potentially weak P2PK outputs. They then need to collaborate with Saoshi to pinpoint these vulnerabilities, and once the proposal is approved, it will be enforced to initiate the freeze.

If given the go-ahead, the freeze feature may be implemented using either a soft fork or a hard fork. A soft fork is a change that’s optional for nodes and is enforced by consensus. Alternatively, a hard fork would involve a thorough rewrite of the fundamental code underlying the Bitcoin blockchain, which all nodes must adopt.

Achieving the freezing of coins linked to Satoshi Nakamoto would necessitate a wide consensus among the Bitcoin community, a task that has proven difficult in the past due to its history of contentious decisions.

The implications of freezing Satoshi’s holdings

Restricting Satoshi’s assets brings up a significant query that tests the core principles underlying the development of digital currencies.

Bitcoin is built as a permanent record that cannot be altered by any single entity, ensuring the integrity of its transaction history. However, this core principle could be undermined if holdings were frozen through a fork, potentially paving the way for future manipulations and a possible erosion of decentralization within the Bitcoin blockchain network.

Supporters contend that Satoshi’s cryptocurrency is a special situation, potentially qualifying as an outlier because of its publicly visible encryption keys and potential impact on the larger digital currency sector.

Given the progress in quantum computing technology, and the possibility that this technology might be used in an attack against the vast Bitcoin hoard (approximately 1 million BTC), could this occurrence serve as a motivator for Satoshi Nakamoto to come forward publicly?
