(2) Extended reading on the development of blockchain in the Internet of Things:

The core technology of blockchain

1. Consensus mechanism, through the voting of special nodes, completes the verification and confirmation of transactions in a very short period of time; for a transaction, if several nodes with unrelated interests can reach a consensus, the entire network can be considered to have done so. Consensus can also be reached. The goal of the blockchain consensus mechanism is to enable all honest nodes to maintain a consistent view of the blockchain.

2. Asymmetric encryption requires two keys for encryption and decryption. These two keys are the public key and the private key. The public key corresponds to the private key. When the public key is used in the encryption process of data, it can only be decrypted by using the corresponding private key. On the contrary, when the private key is used in encrypting the data, only the corresponding private key can be used to decrypt the data. Only the corresponding public key can be decrypted.

『三』 Energy Blockchain Research | The Internet of Things can improve the efficiency of cryptocurrency mining

Everyone who understands cryptocurrency knows the shortcomings of this currency, and its impact on The environment bears the brunt of the impact. Is it possible to mine cryptocurrencies in a green and ethical way? If so, what role will the Internet of Things play in this shift?

Can the Internet of Things be mined?

People started talking about using the Internet of Things for cryptocurrency mining a few years ago. Mining, these discussions have mostly come in the form of warnings: Bad actors could compromise an IoT device and turn it into a distributed cryptocurrency mining network.

Cryptocurrency mining requires powerful central processing units and consumes a lot of energy. Can IoT devices be used to mine cryptocurrency?

Mirai is a household name in the cybersecurity world, but the term is often synonymous with DDoS attacks. IBM's investigation in 2017 found that subsequent Mirai cyberattacks were designed to deploy Bitcoin miner slaves on compromised IoT devices. IBM didn't draw specific conclusions about the effectiveness of leveraging IoT devices, but the concept is intriguing.

Are there other ways IoT, cryptocurrencies, and blockchain can impact each other’s performance?

The Impact of IoT on Cryptocurrency Mining

In Not long after IBM's discovery came out, Avast came to a similar conclusion: This kind of use of the Internet of Things was not only possible, but profitable. Avast estimates that an attacker could mine approximately $1,000 worth of cryptocurrency in four days using 15,000 IoT gadgets simultaneously.

Using thousands of cryptocurrency mining rigs can reduce the overall power consumption and environmental impact of a single cryptocurrency mining operation. There’s an anecdote about a tech blogger who set up and forgot her IoT devices, only to find them generating thousands of dollars worth of tokens in the background for over a year.

Using routers and hotspots as network hubs and cryptocurrency mining hubs has a bright future because it’s about efficiency and being green. After this person writes about her experience, relatedThe order quantity of hotspot equipment has increased to 150,000 units. Compared to expensive CPUs and GPUs, the $400 price tag of this hotspot device is attractive to amateur miners who don’t want to spend a lot of money on cooling systems and graphics cards.

Technologies that make mining more environmentally friendly

Making cryptocurrency mining more environmentally friendly is not an easy task. A single Bitcoin transaction consumes approximately 1,544 kilowatt hours of electricity, which is enough electricity to power an average American household for more than fifty days. The total annual electricity consumption of the Bitcoin network may be as high as 75 terawatt hours.

Smarter climate control technology is one solution. Mining operations can have more granular control over their environment with ductless and mini-split systems. It is much easier to place these units exactly where they are needed, and one outdoor condenser can power multiple cooling units. These devices can save cryptocurrency miners a lot of energy.

As it stands, electricity is a major bottleneck restricting cryptocurrency mining. National and international leaders have prioritized building resilient smart grids in setting goals that rely on the Internet of Things to enable the two-way flow of power and data.

Building energy networks that use renewables and the Internet of Things to be more resilient and performant opens up opportunities for cryptocurrency miners. Some of the larger operations are opening factories in areas rich in solar and wind energy. Other miners work at night to offset the huge impact their operations have on energy consumption during peak electricity usage hours.

Take a mining operation in Texas, for example, that can profit from energy consumption by shutting down for just 30 minutes at a time during its hottest and most expensive days. At night, they can "operate as little as the board can handle" while selling back the contracted power supply to the utility company.

Blockchain and the Internet of Things: A fruitful combination

The Internet of Things and cryptocurrencies have found the right way to complement each other and complement each other. The combination of IoT and blockchain may bring fruitful results, and research and discussions around this topic are proceeding in different ways.

IoT devices rely on high-speed exchange and analysis of field data. Applying blockchain here ensures greater reliability of the system and greater security of data transmission. Autonomy is critical for business efficiency: with blockchain driving IoT interactions, devices can interact directly with each other without involving remote servers.

The technologies used in IoT and cryptocurrency respectively complement each other and bring out the best in each other.
