Proof of Stake Energy Consumption UCL Center for Blockchain Technology

A new study looked into the energy consumption of the most popular proof-of-stake consensus distributed ledger solutions.

Bitcoin is frequently in the news due to its high energy usage, which is prompting miners to use renewable energy sources and other environmental measures.

It’s also driving blockchain developers to think about energy usage in their implementations, with TechPay being a good example of this. TechPay is migrating from a proof-of-work consensus mechanism to a proof-of-stake consensus mechanism.

Proof-of-stake, in which validators must stake in order to participate, has the potential to save energy, especially as the blockchain scales and transaction throughput is expected to reach tens of thousands of transactions per second.

However, new research from University College London shows that different proof-of-stake blockchains consume significantly varying amounts of energy. All six analyzed had consumption levels at least three orders of magnitude lower than Bitcoin, with a similar amount of disparity between the best and worst performers.

According to Dr. Paolo Tasca, Executive Director of the University College London’s Centre for Blockchain Technologies

“However, through this research, we have found that not all proof-of-stake networks are created equally. This is something that both investors and adopters need to be wary of when selecting their network of choice.”

He also recommends keeping an eye on Ethereum 2.0’s possible environmental impact.

Notably, the numbers for proof-of-stake are comparable to those for existing centralized payment systems like VisaNet, implying that they may be undercut in the future.

The researchers link the differences between the systems mostly to the number of validators – without proposing that reducing the number of validators will result in effective centralization – implying the importance of considering design decisions.

They also emphasize the need of selecting appropriate validator hardware, recommending that standardized recommendations be developed to assist operators in selecting the most energy-efficient hardware configuration.

What is the definition of stake proof?

Proof of Stake (PoS) technology allows miners to avoid the energy-intensive cryptographic problem solving required in Proof of Work (PoW) systems. It allows owners to stake their tokens as collateral in exchange for incentives in order to validate transactions on the network by consensus in exchange for rewards, which is commonly done in big public pools.

In practice, this means that PoS does not require additional energy to verify trustworthiness, resulting in a significant reduction in the network’s overall energy consumption.

The proof-of-stake system has various advantages over the proof-of-work method, including increased energy efficiency due to the low energy consumption of mining blocks. Furthermore, creating new blocks does not necessitate cutting-edge technology. Proof-of-stake increases the number of nodes in the network.

Proof-of-stake is a consensus mechanism for cryptocurrencies that allows for the processing of transactions and the creation of new blocks on a blockchain. A consensus mechanism is a way of validating entries in a distributed database while also keeping it secure.

How does a proof of stake work?

The genesis block, which is also hardcoded into the program, is the first block in a PoS blockchain. Following blocks on the blockchain always refer back to previous blocks and contain a complete and up-to-date ledger copy.

Miners do not compete for the right to add blocks to the PoS network. The blocks are commonly referred to as “minted” or “fabricated,” rather than “mined.”

Unlike PoW blockchains, PoS blockchains do not place restrictions on who can propose blocks based on energy use. Despite PoW blockchains’ high energy requirements, new consensus mechanisms such as proof-of-stake reduce the necessity for mining.

The proof-of-stake system has various advantages over the proof-of-work method, including increased energy efficiency due to the low energy consumption of mining blocks.

Furthermore, creating new blocks does not necessitate cutting-edge technology. Proof-of-stake increases the number of nodes in the network.

The presence of more nodes in a network aids in the development of governance standards that give greater resistance to centralization. This is made possible in PoS systems by a higher degree of hardware independence. As a result, proof-of-stake is often seen as the consensus technique that is least likely to result in network centralization.

To be considered for inclusion in the process of adding blocks to a PoS blockchain, users must stake, or lock, a particular amount of the network’s money in a unique contract. The amount of crypto assets they have staked determines their chances of getting chosen as the next block creator.

Users that engage in malevolent behavior risk losing their stake as a result of their activities.

Other determining factors in PoS, such as the length of time a node has staked its money and sheer randomness, may not necessarily favor the wealthiest nodes. Similar to the PoW system, the block reward in PoS refers to a network fee granted by the blockchain to the person who submits a valid block.

Because block selection in PoS is based on coin ownership, exchanges provide staking services, allowing users to stake crypto on their behalf in exchange for more consistent rewards. Stake pools allow several stakeholders to pool their computer resources and increase their chances of being rewarded. To put it another way, they pool their staking power to increase their chances of obtaining block rewards during the verification and validation of fresh blocks.

The benefits and drawbacks of PoS

In PoS, the issue of high levels of energy resource waste has been addressed. PoS-based systems are also significantly more scalable than PoW-based systems, and transactions are accepted far more quickly. By adjusting the system’s parameters or altering its consensus method, the system can accomplish more transactions per second (TPS) than specific, current systems.

The scalability of the PoS network is achieved by establishing a consensus before blocks are built, allowing thousands of requests per second to be processed with less than a millisecond latency spike.

On the other side, proof-of-stake has its own set of issues. The network, for example, continues to be dominated by the largest token holders. Early adopters and those with the most money have more power as a result of this.

Because the concept is so new, it could contain flaws that aren’t yet apparent to the crypto community. Unlike proof-of-work, this paradigm does not have a track record of success. Furthermore, proof-of-stake methods do not automatically discourage forking. When a blockchain splits, validators will receive a duplicate copy of their stake on the freshly forked network. When a validator signs off on both sides of a fork, they can potentially double-spend their coins and receive double the number of transaction fees as a result of the “nothing at risk” conundrum.
