Patent Filing Trends Associated with Power Dissipation in Blockchain

 The worldwide blockchain market is expected to increase from USD 4.9 billion in 2021 to USD 67.4 billion by 2026, indicating that blockchain technology is steadily gaining popularity. To help businesses take advantage of chances in such a situation, it is crucial to comprehend the complexities of this technology and the patent trends related to it. The next page describes blockchain technology, bitcoin mining, industry data connected to the technology, and trends in patents relating to blockchain energy use.

Blockchain and distributed ledger

Blockchain is a distributed public ledger that can be used to record business network transactions. The ledger is copied among the users of a decentralised network and is decentralised as a blockchain database. All members of the network can then access the distributed ledger and its unchangeable record of transactions. A block of data can be used to record each transaction. In other words, a collection of transactions are contained in each block. A record of each new transaction that occurs in the blockchain is immediately recorded to each participant's ledger. Each transaction in the distributed ledger is confirmed by the agreement of several system users.

Each block in blockchain is identified by its hash. Similar to this, every block contains a reference to the parent block, which is its preceding block. The parent block's N+1hash changes if any changes are made, which ultimately affects the hash of the current block. This is so that the cryptographic hash can link the blocks together.

A number of blockchain platforms offer a way to create apps based on the blockchain. Bitcoin, Ethereum, Ripple, Quorum, and Hyperledger are some of the well-known ones.

Different blockchain networks employ various methods of validation. For instance, Proof-of-Work (PoW) is used by Bitcoin, Proof-of-Stake (PoS) by Ethereum, and Byzantine Fault Tolerance (BFT) by Ripple.

In order to confirm transactions and create new coins for cryptocurrencies like Bitcoin, Proof-of-Work, a decentralised consensus mechanism, is frequently utilised in mining operations. By producing the right hash, a new block can be mined, or added to the blockchain, and is then disseminated throughout the network. About every 10 minutes, a new block for Bitcoin is added to the blockchain. In contrast, the Proof-of-Stake idea allows users to mine and validate block transactions based on the quantity of coins they possess.

Bitcoin Mining and Energy Consumption

Different miners compete with one another to finish transactions by cracking the riddles and adding a block to the Blockchain network throughout the mining process. Miners contribute to the network's security and decentralisation by producing the blocks by resolving these computationally challenging mathematical riddles. For every successful hash value, the miner receives a block reward.

Extremely specialised hardware and a lot of power are required for the mining operation. The mathematical conundrum is always solved in 10 minutes thanks to the Bitcoin programme. The challenge becomes harder and uses more processing power as the number of miners rises. According to statistics from the Cambridge index, the electricity used by all business buildings in the US over the course of two months is slightly more than what is used in one day of Bitcoin mining.

Advanced ASIC processors, like the NVidia CMP HX, are necessary for the rigs to quickly mine Bitcoins. Heavy-duty GPUs are used in the rigs, which need high-wattage power sources to do the mining algorithms. There has recently been a global scarcity of chips in the semiconductor sector as a result of the rise in demand from cryptocurrency miners.

Air conditioners and powerful computer processors are used in mining to keep the CPUs cool while they work nonstop on difficult calculations. Everything about that uses way too much electricity.

Additionally, in all geographical areas, including Asia Pacific, Europe, and Latin America, at least 60% of cryptocurrency miners use hydroelectric energy. On the other side, less of the other clean energy sources are used.

Solar energy is an example of a renewable energy source that has issues because it cannot consistently and adequately produce enough electricity for non-stop trading throughout the day.


For Bitcoin miners, who only have a very limited time to recoup their investment, shutting down for any length of time is incredibly undesirable. The founder of the website Digiconomist, which tracks cryptocurrency's energy use, Alex de Vries, was quoted by a news agency as saying that in terms of profit maximisation, companies will always prefer never having to shut down.


As fossil fuels are cheap and a reliable source of energy, Alex de Vries continued, "this makes them the ideal consumer for them rather than renewables."


The University of Cambridge Centre for Alternative Finance (CCAF) has calculated the annualised total energy consumption of Bitcoin in terawatt hours and evaluates the growing market for cryptocurrencies (TWh). Bitcoin uses 101 terawatt hours (TWh) yearly at its current rate. Bitcoin would rank among the top 30 energy consumers in the world if it were a nation.

Bitcoin Mining and Carbon Footprint

The fact that Bitcoin mining produces carbon footprints similar to that of New Zealand is another problem. Within less than three decades, the carbon dioxide produced by bitcoin might raise the global warming temperature above 2 °C.

How to Overcome Bitcoin Mining Drawbacks?

As previously mentioned, mining bitcoins consumes as much electricity as a medium-sized nation. However, there aren't many simple ways to do it.

1. Proof-of-Stake: Because it eliminates mining competition, it is more energy efficient than Proof of Work. Block transactions are verified using PoS based on the ownership of the underlying currency. It does away with the need to use a significant amount of electricity to authenticate the blocks. In Ethereum, proof of stake is employed. Ethereum is switching from proof-of-work to proof-of-stake, in other terms. Figure 8 of the following figure shows how much less electricity Ethereum needs than PoW.

2. Proof of authority (PoA): Under PoA, the nodes, also known as validators, who have demonstrated their authority to do so are granted the right to create new blocks. There is no competition between the validators in Proof of Authority. Furthermore, it runs without electricity.

Patent Drafting and Prior Art: Strategies for Navigating the Patent Landscape

 Patent Drafting and Prior Art: Strategies for Navigating the Patent Landscape Patent drafting is the process of creating a detailed document that describes an invention and its components, as well as the steps for making and using it. Prior art, on the other hand, refers to existing public knowledge and technologies that may affect the novelty or non-obviousness of an invention. In the complex and constantly evolving world of patent law, it is essential to understand both of these concepts and how to navigate the patent landscape effectively. In this article, we will discuss some strategies for patent drafting and dealing with prior art. Start with a clear and concise description of the invention The first step in patent drafting is to create a detailed description of the invention. This should include information about what the invention is, how it works, and what makes it unique or different from existing technologies.
