Bitcoin is considered to be one of the strongest distributed systems ever created. Since its inception, it has been running block-by-block for fifteen years. Only two interruptions occurred during the first five years. These were quickly resolved by developers. Apart from that it produced roughly one block every ten minute with no interruptions.
Bitcoin users are encouraged to think of Bitcoin as unstoppable because it is so reliable. Many people believe that Bitcoin is already the winner, and they are just beginning to realize this. “Bitcoin is inevitable” Many would agree.
Bitcoin may not be unstoppable, but there are some events that can cause chaos or damage to the Bitcoin network. Today, we’ll look at a couple of examples and determine how likely they are to play out.
Government Intervention
Bitcoin poses a conundrum to governments around the world in several ways. Bitcoin is first and foremost a payment system which allows global payments from user to user, without regard to borders. financial controls.
Governments can impact Bitcoin participants by introducing regulations. To disrupt Bitcoin, governments will have to target the miners who add blocks to the Blockchain to maintain the progress of the system.
This was done before In 2021, the Chinese government will ban bitcoin mining. As Chinese miners began to migrate abroad, almost 50% of network hashrate was taken offline.
The network did not stop.
In a worst-case scenario the Chinese government might have forced the confiscation of all mining equipment. The CCP would then have control over all those miner, who could be used to engage in other activities. 51% attack The network is not working. This didn’t occur. It was unlikely that the mining ban would have worked, even if a confiscatory strategy had been used.
Iran was, for instance, one place where a large amount of hashrate moved. Many rumors were spread at the time that miners had bribed Iranian military officials to help them get past the customs and into the country.
It is possible to bribe government officials and illegally smuggle out equipment if they try to close borders or seize equipment. financial incentive to do so. A government must be able seize more than 51% of active hashrate for such an event to pose an existential threat to the network. A small percentage would be enough to get through the border to make sure that the remaining hashrate did not exceed the 51% threshold.
Hashrate is decentralizing around the globe and the risk of a similar action posing a danger to Bitcoin keeps shrinking. Although it is possible, the probability of this happening decreases the more governments are involved. Bitcoin’s resilience is evident, as the CCP actions in 2021 have empirically shown.
Electrical Grid Failure
Bitcoin mining is impossible without electricity. This is a fact, since they’re just computers. It’s a serious risk for miners, who depend on infrastructure that provides power and delivers it.
Power outages and grid problems can be caused by a variety of natural disasters. Extreme weather conditions like extreme cold can cause power grids to be disrupted. In Texas, hashrates were affected by the winter storm Uri of 2021. However, the scale of such events does not pose an immediate systemic threat to Bitcoin. Even if Texas lost power with only 30% network hashrate in the state, it would not cause the Bitcoin network to crash or be destroyed.
Even though 50% the hashrate of the Chinese network went offline, in a short amount of time in 2021 the network still functioned. The blocktime interval did increase dramatically, causing a spike in transaction fees The network continued to process transactions and confirm transactions, even though the confirmations were made quickly.
If we imagine an event of a greater scale, for example, a huge solar storm, which knocks out electricity to half the world, the remaining half still has power. This half of earth would have power, the miners would be able to continue their mining activities, confirm the transactions and continue the functioning of the network. As long as the seed phrase is kept in a safe place, people who are on a half of the planet without electricity can still access their money when power comes back or they move to an area with functioning grid.
Bitcoin will continue to chug along in the corner until power comes back on. “regenerate” It is expanding around the world.
Internet Disruptions
Although the Internet is comprised of decentralized protocols, similar to Bitcoin’s mining infrastructure, its actual infrastructure is largely owned by multinational corporations and government (again like Bitcoin infrastructure). This infrastructure’s ownership is distributed globally among a number of players, although it does not reach the level of a decentralized mesh network.
It is still possible to attack or disrupt large bottlenecks, which can lead to a significant degradation in reliability and function. Most people connect to the internet via an Internet Service Provider. This market, however, is controlled by only a few large ISPs in each region. It’s hard to choose between the many providers and it can be a big problem for those who use the internet. There is no alternative provider if an ISP denies or blocks access, and there aren’t any other providers to choose.
The ability to speak to someone in another country is due to greater factors. “backbone” Underwater fiber-optic cable networks and major corporation’s networks. The cables act as centralized communication chokepoints between continents and countries. The operators could filter the information that passes through the cables, or someone might physically cut the cables. This would cause a massive interruption of internet traffic around the world.
What could be done in the event of either one? If the ISP starts filtering Bitcoin to its users, then people’s nodes will be cut off from the network. Depending on the severity of ISP filtering, broadcasting transactions may be impossible. The rest of the network will continue to function. Blockstream offers satellite feeds, but bitcoin is so small that even a momentary connection would broadcast the payment.
Interruptions of larger scales between countries or areas are not as serious in the overall scheme of things. What if a nation like Russia’s internet connection was completely cut off from the rest of the world? Blockchain would be threatened if Russian miner’s didn’t stop. fork The blocks from miners in Russia and those outside the country would never be received by each other. When the connection is repaired, the group that mined longer chains will simply continue to do so. “overwrite” You can delete the transaction history from the smaller chain.
In such situations, it is possible that a chain split will not even happen. Blockstream’s satellite service It allows users to still receive real-time blocks even if they don’t have internet. Combining this with radio relays or satellite uplinks that are harder to stop, Russian miners could continue to mine a blockchain in real time with the rest.
Bitcoin has proven its resilience yet again.
Wrap Up
Bitcoin’s resilience is incredible, even in the face threat or disruption to the network. The network was designed specifically to work this way. Bitcoin is a great example of a decentralized network that has been designed to be resilient in the face threats and disruptions.
World has seen and continues to witness incredibly destructive events. Bitcoin is a resilient currency that has already survived countless events. Bitcoin will likely survive whatever is thrown its way in the future.
Although it’s resilient, Bitcoin is not invincible. Bitcoin would have to be taken offline by a catastrophe of such massive proportions that, in the rare event of it happening, there would be much worse problems for us than Bitcoin failing to work.
