In the ever-evolving realm of cryptocurrency, two prominent players have captured the attention of enthusiasts and investors alike: Solana and Ethereum. 

As crypto beginners embark on their journey into the decentralized world, understanding the nuances between these platforms becomes crucial. 

In this comprehensive guide, we'll delve into the features, pros, and cons of both Solana and Ethereum to empower you with the knowledge needed to make informed decisions.

Understanding Solana

Solana, often hailed as a high-performance blockchain, stands out for its remarkable scalability and low transaction costs. Launched in 2020, it aims to address some of the scalability issues faced by earlier blockchain networks and has become a go-to for blockchain developers despite such a short timeline.

The team behind Solana is known as Solana Labs that was founded in 2017 by Anatoly Yakovenko and Raj Gokal. They proposed the idea of Solana with their whitepaper titled “Solana: A new architecture for a high performance blockchain”. 

Solana, much like Ethereum, uses the Proof of Stake (PoS) consensus mechanism which aims to build on Proof of Work first proposed by the Bitcoin Network. Proof of History (PoH) is also an important consensus mechanism used within Solana. 

It aims to achieve both security and scalability. PoH leverages cryptographic techniques to create a historical record that efficiently proves the order and timing of transactions, enhancing the trustworthiness of the distributed ledger.

Solana's Native Coin: SOL (Solana Coin)

SOL, the native cryptocurrency of the Solana network, fuels transactions and smart contracts. Known for its rapid confirmation times and low fees, SOL has garnered attention as a potential investment and a key competitor to ETH.

The SOL token has been a main talking point for crypto investors since its inception back in 2020. During the 2021 bull run, Solana’s native token hit all time highs of $249 and is currently climbing back up as we go into the early months of 2024.

At the start of 2023 it seemed all but over for Solana. Outages on the network compromised the security and sent the token crashing. Since then it has steadily climbed back up in value thanks to a number of positive headlines, updates from the team and a loyal community.

Solana’s Collaboration with VISA

Summer drew to a close in September and it seemed like crypto was in a bit of a gray area as the FTX trial was well underway. 

That was until Solana announced their official partnership with VISA, one of the world’s most prominent names in traditional finance. VISA would begin to utilize the Solana network to process transactions and gain exposure to the blockchain.

VISA sees vlue in the high throughput of transactions and scalability brought forward by Solana. Transactions for VISA’s stablecoin settlement will be used with Solana.

Significant Updates on Solana

On the Solana website is a backlog of updates that have been executed on the network:

• QUIC - built by Google to digest transactions. It will become the default transaction ingestion protocol for Solana.
• Stake-weighted QoS - is built in conjunction with QUIC. Transactions no longer are accepted on a first come first serve basis and instead it is reliant on the source.
• Fee markets - allows users to add urgency to transactions in the form of additional fees so their transactions are added before others.
• Transaction size increase - QUIC has allowed transactions to increase from the original 1,232 bytes.
• Compact vote state - voting state is lowered allowing better overall performance on the blockchain.

Key Features of Solana

Here is a breakdown of some of the key features associated with Solana, its network and token.

High throughput: Solana boasts an impressive throughput, with the capability to process 50,000 transactions per second (TPS).

Low transaction costs: Solana's innovative design contributes to minimal transaction fees, making it an attractive option for users.

Unique consensus mechanism: Proof of History is Solana’s consensus mechanism. It is based on PoS but uses a different method to calculate time. Transactions on the blockchain are verified through a sequence of historical hashes. 

Ethereum Unveiled

Ethereum, the pioneer in smart contract functionality, revolutionized the crypto space when it was introduced in 2015. It serves as a decentralized platform for creating and executing smart contracts.

The team behind Ethereum is Vitalik Buterin and Gavin Wood who first introduced the idea of the blockchain in a whitepaper titled “A Next-Generation Smart Contract and Decentralized Application Platform”.

In 2022 Ethereum started making  the switch to PoS from PoW to create a more sustainable and robust network. More on that below!

Ethereum was initially built to overcome the limitations of Bitcoin. While revolutionary, Bitcoin is extremely limited in its functionality and it didn’t take long for developers like Vitalik to notice this. For new users to be onboarded into crypto and Web3 something needed to change and that’s where Ethereum comes into play.

Ethereum's Native Coin: ETH (Ethereum Coin)

ETH, Ethereum's native cryptocurrency, fuels the network by facilitating transactions and executing smart contracts. As one of the most traded cryptocurrencies, ETH holds significant market value and continues to be a runner up behind Bitcoin in terms of influence and market share.

The Ethereum token brought on a new way to invest and earn with crypto as they made the all important switch to the PoS consensus mechanism. It is now possible to stake crypto and become an active contributor to a number of blockchains through this practice.

As well as the Ethereum native token being a popular choice for investors, new possibilities were brought forward by the token and blockchain.

ERC-2O tokens are hosted via Ethereum network and harness the functionalities and more. Whether it is a gaming token like SAND or a protocol token like SUSHI, both of these tokens are built with Ethereum’s consensus mechanism and the necessity for decentralization and scalability.

There are more than 280,000 ERC-20-compliant tokens built on Ethereum. Over 40 of them make up the top 100 cryptocurrencies by market capitalization which points towards the overall popularity of both the token and network!

Ethereum 2.0 and Its Significance

Ethereum 2.0, also known as ETH 2.0 or Serenity, is a major upgrade to the Ethereum blockchain aimed at improving scalability, security, and sustainability. 

The upgrade is being rolled out in multiple phases, with the transition from the current Proof of ork (PoW) consensus mechanism to a Proof of Stake (PoS) mechanism being a central component. 

The primary goals of Ethereum 2.0 include:

Scalability: Ethereum 2.0 aims to address the scalability issues faced by the current Ethereum blockchain, which has been known for its limited transaction throughput. 

Security: PoS is designed to enhance the security of the Ethereum network by relying on validators who lock up a certain amount of cryptocurrency (ETH) as collateral. Validators are chosen to create new blocks and validate transactions based on the amount of cryptocurrency they hold and are willing to "stake" as collateral.

Sustainability: Ethereum 2.0 aims to make the network more sustainable by transitioning from a resource-intensive PoW algorithm (used in mining) to a PoS algorithm. This shift is expected to reduce the environmental impact of Ethereum mining.

The Ethereum 2.0 upgrade is being implemented in multiple phases:

Phase 0 (Beacon Chain): The Beacon Chain, which is the PoS blockchain running in parallel with the existing PoW chain, was launched in December 2020. Validators can start staking on the Beacon Chain, but full functionality is yet to be implemented.

Phase 1: This phase is expected to introduce shard chains, which are smaller chains running in parallel to the main Ethereum chain. Shard chains aim to increase transaction throughput.

Phase 1.5: This is a crucial phase involving the transition from PoW to PoS. The Ethereum mainnet will become a shard on the Ethereum 2.0 network, and PoW will be replaced by PoS. 1.5 also aims to bridge 

Phase 2: Focused on further improvements and enhancements to the Ethereum 2.0 network. 

Shanghai Update: This is the most recent installation of the Ethereum 2.0 update that came in April 2023. Code has been implemented to perform rollups at a faster and cheaper rate. Shanghai has also allowed users to withdraw their staked ETH tokens which wasn’t possible before.
