Tax Impact on Bitcoin and Cryptocurrency Investment

Quantum computers and the Bitcoin blockchain has been saved. Quantum computers and the Bitcoin blockchain has been removed. One of the most well-known applications of quantum computers is breaking the mathematical difficulty underlying most of currently used cryptography. Since Google announced that it achieved quantum supremacy there has been an increasing number of articles on the web predicting the demise of currently used cryptography in general, and Bitcoin in particular.

The goal of this article is to present a balanced view regarding the risks that quantum computers pose to Bitcoin. A great amount of digital ink has been spilled on the topic of how quantum computers pose an existential threat to currently used asymmetric cryptography.

We will therefore not discuss this in detail, but only explain the aspects that are relevant for the analysis in this article. In asymmetric cryptography, a private-public key pair is generated in such a manner that the two keys have a mathematical relation between them. As the name suggests, the private key is kept as secret, while the public key is made publicly available. This allows individuals to produce a digital signature using their private key that can be verified by anyone who has the corresponding public key.

This scheme is very common in the financial industry to prove authenticity and integrity of transactions. This principle dictates that the public key can be easily derived from the private key but not the other way around. All known classical algorithms to derive the private key from the public key require an astronomical amount of time to perform such a computation and are therefore not practical.

However, in , the mathematician Peter Shor published a quantum algorithm that can break the security assumption of the most common algorithms of asymmetric cryptography. This means that anyone with a sufficiently large quantum computer could use this algorithm to derive a private key from its corresponding public key, and thus, falsify any digital signature. To understand the impact of quantum computers on Bitcoin, we will start with a brief summary about how Bitcoin transactions work.

Bitcoin is a decentralized system for transferring value. Unlike the banking system where it is the responsibility of a bank to provide customers with a bank account, a Bitcoin user is responsible for generating his own random address. By means of a simple procedure, the user's computer calculates a random Bitcoin address related to the public key as well as a secret private key that is required in order to perform transactions from this address.

Moving Bitcoins from one address to another is called a transaction. Such a transaction is similar to sending money from one bank account to another. In Bitcoin, the sender must authorize their transaction by providing a digital signature that proves they own the address where the funds are stored.

In the Bitcoin network, the decision of which transactions are accepted into the network is ultimately left to the so called miners. Miners compete in a race to process the next batch of transactions, also called a block. Whoever wins the race, is allowed to construct the next block, awarding them new coins as they do so. Bitcoin blocks are linked to each other in a sequential manner. The victorious miner who creates a new block, is free to include whichever transaction they wish.

Other miners express their agreement by building on top of blocks they agree with. In case of a disagreement, they will build on the most recently accepted block. In other words, if a rogue miner attempts to construct an invalid block, honest miners will ignore the invalid block and build on top of the most recent valid block instead.

Bitcoin transactions allow for a custom logic to be implemented, enabling a myriad of financial transaction types such as escrow and shared ownership. However, for the purpose of this article, we restrict ourselves to simple person-to-person payments. These can be divided into 2 categories, each affected differently by a quantum computer.

In the first type, a public key directly serves as the Bitcoin address of the recipient. In the early days of Bitcoin, in , this was the dominant address type. Many of the original coins mined by Satoshi Nakamoto himself are still stored in such addresses.

One of the issues with these addresses is the lack of a mechanism to detect mistyping of addresses for example a last checksum digit which is used, for example, in credit card numbers. An additional problem is that these addresses are very long, which results in a larger transaction file and therefore longer processing time.

Regarding the threat from a quantum computer, the public key is directly obtainable from the address. Since all transactions in Bitcoin are public, anyone can obtain the public key from any p2pk address. This would allow an adversary who has a quantum computer to spend the coins that the address had.

In the second type of transaction, the address of the recipient is composed of a hash of the public key. As a hash is a one-way cryptographic function, the public key is not directly revealed by the address. As was mentioned above, the public key cannot be retrieved from the address. The public key is only revealed at the moment when the owner wishes to initiate a transaction. This means that as long as funds have never been transferred from a p2pkh address, the public key is not known and the private key cannot be derived using a quantum computer.

If funds are ever transferred from a specific p2pkh address no matter what amount , the public key is revealed. From that moment on, this address is marked "used" and should ideally not be used again to receive new coins.

In fact, many wallets are programmed to avoid address reuse as best they can. Avoiding the reuse of addresses is considered best practice for Bitcoin users, but you would be surprised how many people do not take this advice to heart.

More on that in the following chapter. Imagine that someone manages to build a quantum computer today and is therefore able to derive private keys. How many Bitcoins will be in danger? To answer this question, we analyzed the entire Bitcoin blockchain to identify which coins are vulnerable to an attack from a quantum computer.

As explained in the previous section, all coins in p2pk addresses and reused p2pkh addresses are vulnerable to a quantum attack. The result of our analysis is presented in the figure below. It shows the distribution of Bitcoins in the various address types over time. As can clearly be seen in the graph, p2pk addresses dominated the Bitcoin blockchain in the first year of its existence. Interestingly, the number of coins in p2pk addresses has stayed practically constant circa 2M Bitcoins.

A reasonable assumption is that these coins were generated through mining and have never been moved from their original address. As p2pkh was introduced , it quickly became dominant. Most of the coins created since then are stored in this type of address.

In the graph we see that the number of Bitcoins stored in reused p2pkh increases from to , and since then is decreasing slowly to reach the current amount of 2. This suggests that people are generally following the best practice of not using p2pk address as well as not reusing p2pkh addresses.

At the current price this is over 40 billion USD! Figure 1: The distribution of Bitcoins that are stored in address that are vulnerable to quantum attacks. Note that reused Segwit coins are presented in the graph but are otherwise not mentioned in the article.

What can one do to mitigate the risk of Bitcoins being stolen by an adversary with a quantum computer? In the previous section we explained that p2pk and reused p2pkh addresses are vulnerable to quantum attacks. However, p2pkh addresses that have never been used to spend Bitcoins are safe, as their public keys are not yet public. This means that if you transfer your Bitcoins to a new p2pkh address, then they should not be vulnerable to a quantum attack.

The issue with this approach is that many owners of vulnerable Bitcoins have lost their private keys. These coins cannot be transferred and are waiting to be taken by the first person who manages to build a sufficiently large quantum computer. A way to address this issue is to come to a consensus within the Bitcoin community and provide an ultimatum for people to move their coins to a safe address. After a predefined period, coins in unsafe addresses would become unusable technically, this means that miner will ignore transactions coming from these addresses.

Such a drastic step needs to be considered carefully before implemented, not to mention the complexity of achieving consensus about such a sensitive issue. Does that mean that the Bitcoin blockchain is no longer vulnerable to quantum attacks? The answer to this question is actually not that simple. In such an attack, the adversary will first derive your private key from the public key and then initiate a competing transaction to their own address.

They will try to get priority over the original transaction by offering a higher mining fee. In the Bitcoin blockchain it currently takes about 10 minutes for transactions to be mined unless the network is congested which has happened frequently in the past. As long as it takes a quantum computer longer to derive the private key of a specific public key then the network should be safe against a quantum attack. Current scientific estimations predict that a quantum computer will take about 8 hours to break an RSA key , and some specific calculations predict that a Bitcoin signature could be hacked within 30 minutes.

This means that Bitcoin should be, in principle, resistant to quantum attacks as long as you do not reuse addresses. However, as the field of quantum computers is still in its infancy, it is unclear how fast such a quantum computer will become in the future. If a quantum computer will ever get closer to the 10 minutes mark to derive a private key from its public key, then the Bitcoin blockchain will be inherently broken.

Quantum computers are posing a serious challenge to the security of the Bitcoin blockchain. In case your own Bitcoins are safe in a new p2pkh address, you might still be impacted if many people will not or cannot take the same protection measures.

In a situation where a large number of Bitcoins is stolen, the price will most likely crash and the confidence in the technology will be lost. Even if everyone takes the same protection measures, quantum computers might eventually become so fast that they will undermine the Bitcoin transaction process. In this case the security of the Bitcoin blockchain will be fundamentally broken.

These types of algorithms present other challenges to the usability of blockchains and are being investigated by cryptographers around the world. We anticipate that future research into post-quantum cryptography will eventually bring the necessary change to build robust and future-proof blockchain applications.

As part of Bitcoin's coin issuance, miners are rewarded a certain amount of bitcoins whenever a block is produced approximately every 10 minutes. When Bitcoin first started, 50 Bitcoins per block were given as a reward to miners. After every , blocks are mined approximately every 4 years , the block reward halves and will keep on halving until the block reward per block becomes 0 approximately by year As of now, the block reward is 6. Bitcoin was designed as a deflationary currency. Like gold, the premise is that over time, the issuance of bitcoins will decrease and thus become scarcer over time.

The uncomplicated way to define the Bitcoin network is to consider it as a distributed ledger of wallet balances, denominated in Bitcoin. Why is it distributed? Because everything is stored on a large number of computers across the world, which gives redundancy against any sole point of failure. While one individual, territory or country could be dis-connected from the network, Bitcoin is efficient as long as there are two or even more instances of the program running.
