CRYPTOCURRENCY MECHANISMS – Basics, Differences and Impact of Proof-of-Work and Proof-of-Stake

Among cryptocurrency traders and investors, there is often interest in the consensus mechanisms that make blockchains work. In today’s Strifor review, we’ll cover two of the most well-known of them – Proof-of-Work (PoW) and Proof-of-Stake (PoS). We will analyze how they work, what are their main differences, as well as their impact on crypto trading and investment.

Proof-of-Work: Energy-intensive but time-tested

Proof-of-Work was the first consensus mechanism introduced into the blockchain on which Bitcoin operates. Its essence involves solving complex math problems by miners who compete for the right to add blocks to the chain.

• Pros:

• High level of security. Due to decentralization and the complexity of allowing attacks, PoW is considered resistant to most threats.
• Proven stability. Bitcoin and a number of other popular cryptocurrencies have been operating on this mechanism for over a decade.

• Minuses:
• High power consumption. According to the Cambridge Bitcoin Electricity Consumption Index, mining consumes more energy than some countries.
• Limited scalability. The bandwidth of such networks is limited by the amount of computation.

For traders, PoW-based cryptocurrencies such as Bitcoin and Litecoin are attractive for their liquidity and historical stability, but their volatility is often linked to environmental and regulatory news.

Proof-of-Stake: Green and the new era of blockchain

Proof-of-Stake was created as a more energy efficient alternative to PoW. In PoS, blocks are added by validators that hold a certain number of tokens (steak them). The more tokens in the steak, the higher the chance of being selected to create a new block.

Pros:

• Low power consumption. PoS networks are much less dependent on electricity, making them environmentally sustainable.
• High scalability. Transactions are processed faster, which is critical for DeFi and other large-scale applications.

Cons:

• Centralization risk. The more tokens a single participant has, the greater its impact on the network.
• Security complexity. PoS is relatively young, and its resistance to attacks is not yet fully time-tested.

Examples of PoS cryptocurrencies include Ethereum (with the transition to Ethereum 2.0), Solana, Cardano, and Polkadot. These assets are popular among crypto traders due to their fast network and innovation.

Etherium’s transition to Proof of Stake 

September 2022 saw one of the most significant events in cryptocurrency history – The Merge. Efirium, the second most capitalized cryptocurrency in the world, completed its long-awaited transition from the Proof of Work (PoW) algorithm to Proof of Stake (PoS). The switch to PoS has reduced the power consumption of the Etherium network by 99.95%. This was a key step to address the environmental criticism that has often been levied against cryptocurrencies. Now, Efirium is one of the greenest blockchain networks, which opens up new opportunities for mass adoption.

Proof of Stake has made the network more secure against attacks, as validators are now interested in the long-term support of the system. In addition, the move has prepared Etherium for future upgrades such as sharding, which will significantly increase network capacity and reduce transaction fees.

Proof-of-Work vs Proof-of-Stake: Which to choose?

• Traders often prefer PoW assets for their high liquidity and long history in the market. However, the trend towards sustainability is gradually raising interest in PoS.
• Investors see PoS cryptocurrencies as more promising long-term investments, especially given the growth of DeFi and NFT, which are actively using PoS platforms.

The choice between Proof-of-Work and Proof-of-Stake is a choice between time-tested reliability and innovative efficiency. It is important for traders and investors to consider both the technical features of consensus mechanisms and their impact on asset value, liquidity and volatility. It is important to keep an eye on technological developments and regulatory changes to maximize market opportunities.
