How does Solana work?

Solana's blockchain technology is distinguished by its unique and efficient approach to achieving scalability and security, primarily through its innovative hybrid protocol. This protocol combines proof-of-stake (PoS) and proof-of-history (PoH) mechanisms to optimize the network's functionality.

Proof-of-History (PoH):

At the core of Solana's protocol, PoH acts as a digital record, confirming events on the network at any given time. It functions like a cryptographic clock, providing a timestamp for every transaction.
PoH is conceptualized as a high-frequency Verifiable Delay Function (VDF), ensuring the orderly progression of the network by validating that block producers have waited the necessary time before moving forward.
This mechanism uses a 256-bit secure hash algorithm (SHA-256) to maintain a consistent and real-time data flow, enhancing the network's ability to handle transactions efficiently.

Proof-of-Stake (PoS):

In conjunction with PoH, PoS plays a vital role in transaction validation. Validators are selected based on the amount of cryptocurrency they have staked, with rewards given for confirming new transaction blocks.
The Tower Byzantine fault tolerance (BFT) algorithm, an optimized version of the practical Byzantine fault tolerance protocol, is employed within the PoS system to maintain network security and functionality.

Combined Efficiency:

The integration of PoH with PoS enables Solana to reach consensus quickly, keeping the network secure and operational.
PoH's timestamping of transactions reduces the need for validator nodes to communicate extensively with each other to confirm transaction times, significantly speeding up the process.

All nodes on Solana are equipped with cryptographic clocks, streamlining the tracking of events and reducing the dependency on other validators for transaction verification.

This dual mechanism approach allows Solana to offer high transaction throughput and rapid block creation times, setting it apart in the blockchain space and contributing to its scalability and user experience.

The Solana (SOL) token

Solana's native cryptocurrency, SOL, is currently valued at around $58. Launched in March 2020, SOL serves as both a utility token and a means of value transfer within the Solana blockchain. It plays a crucial role in maintaining network security through staking and has quickly risen to become one of the top 10 cryptocurrencies by market capitalization.

In terms of functionality, the SOL token operates similarly to Ethereum's native token, but with a key difference in its usage within the network's consensus mechanism. SOL token holders engage in staking to validate transactions, leveraging Solana's proof-of-stake (PoS) system. Additionally, the token is used for transaction fee payments, reward distribution, and enabling holders to partake in governance decisions.

For those interested in the technical specifics, over 500 million SOL tokens are expected to be released into circulation. The current total supply has surpassed 511 million, with approximately half of that in circulation. Notably, about 60% of SOL tokens are held by Solana's founders and the Solana Foundation, leaving 38% allocated for community members.

For those looking to acquire SOL, it's available on most major cryptocurrency exchanges, including Binance, Coinbase, KuCoin, Huobi, FTX, and others. This accessibility makes it a popular choice for traders and investors alike.
