An Introduction To Solana: Innovations, Characteristics, And Criticism

Will Solana be the one? The race to be the prime smart-contract-enabled blockchain is heating up. Many tasks are chasing Ethereum’s tail, providing quicker and cheaper transactions plus technological improvements. What does Solana supply? An inside clock. An extremely greater variety of transactions. Fees so low which might be nearly non-existent. The chance to scale to international adoption of their layer 1.

Will this be sufficient to seize the market? Is Solana the legendary Ethereum-killer that everybody is searching for? Keep studying and get sufficient data to make your individual thoughts. We’ll summarize the nice, the unhealthy, and the ugly in digestible bullet factors and quick textual content.

What Is Proof Of History And How Does It Work? 

Contrary to what the identify suggests, proof of historical past will not be a consensus mechanism. Solana makes use of Proof-Of-Stake to validate its blocks. “The core Solana innovation is Proof of History (POH), a globally-available, permissionless source of time in the network that works before consensus,” says the next video’s info field. 

To drive the purpose residence, let’s additionally quote Techcrunch:

Enter Yakovenko’s huge concept, which he calls “proof of history,” whereby the Solana blockchain has developed a type of synchronized clock that, in essence, assigns a timestamp for every transaction and disables the power for miners and bots to resolve the order of which transactions get recorded onto the blockchain. Yakovenko says doing so permits for better safety and “censorship resistance.”

Solana’s creator is Anatoly Yakovenko, a San Francisco resident “who spent more than a dozen years as an engineer working on wireless protocols at Qualcomm.” He wasn’t curious about cryptocurrencies till he discovered a method to enhance the system. In conventional blockchains, the blocks don’t carry a timestamp and that results in inefficiencies. Yakovenko discovered a method to embrace it within the SHA-256 (Secure Hashing Algorithm 256) hash perform, and the remainder is historical past… proof of historical past.

Other Innovations That The Solana Blockchain Offers

This part would be the solely technical a part of the article, we promise. To begin, we’re going to cite EVALUAPE’s evaluation. They’re “a platform for demonstration and evaluation of blockchain projects.”

VDF, Verifiable Delay Function:

A perform used to generate PoH. It is a collision resistant hash perform. In quick, this can be a perform that takes a bunch of knowledge inputs and spits out an output in fastened measurement. The most important benefit of the perform is its safety.

Avalanche Communication: 

Simply talking, for the reason that hash worth in each timestamp is calculated by the earlier hash worth, an extended vary of hash worth may be broke into small partitions to be verified individually by the nodes. Each node solely must confirm a partition of hash worth, after which concatenate and restore to an extended hash worth. 

And for the following batch, we’ll quote Decrypt’s evaluation of the Solana platform.

Tower Consensus, a variant of Proof-Of-Stake that:

Enables distributed networks to succeed in consensus regardless of assaults from malicious nodes, often known as Practical Byzantine Fault Tolerance (PBFT).

Solana’s implementation of PBFT enforces a worldwide supply of time throughout the blockchain by way of a second novel protocol often known as Proof of History (PoH).


This permits for a parallel good contracts runtime that optimizes sources and ensures that Solana can scale horizontally throughout GPUs and SSDs, which ought to assist the platform scale to fulfill calls for.

Gulf Stream:

Solana additionally utterly nixes the mempool system utilized by different platforms, and as a substitute forwards transactions to validators even earlier than the earlier batch of transactions is finalized. This helps to maximise affirmation pace and enhance the variety of transactions that may be dealt with each concurrently and in parallel. 

Key Characteristics Of The Solana Blockchain

  • Technically, it’s nonetheless in beta. Their MainNet is up and working, although.
  • Low barrier of entry to develop into a validator. There’s no minimal stake to start out validating, however the opportunity of being chosen is instantly tied to the dimensions of your stake.
  • It’s even quicker than legacy monetary programs AND centralized cryptocurrency exchanges. 
  • Over 100 tasks have been constructing on Solana by the top of 2020. Now, there are greater than 250. The development is exponential.
  • At the time of writing, their official stats report 905 validators and 1331 nodes. The Avg. price per transaction is $0.00025.
  • They at the moment report 1,375 transactions per second.
  • The venture helps good contracts in any programing language.

Powerful Allies And Co-Signs

  • It’s the “official chain” for USDC. And USDC is the second-largest stablecoin on the earth.
  • Sam Bankman-Fried’s FTX and Alameda Research. Their Serum DEX runs on Solana, in addition to their tasks and Oxygen, a borrowing/lending DeFi protocol.

Solana, Criticism And Scandals 

  • Even although they’ve ample documentation freely obtainable, the venture doesn’t have a clearly outlined roadmap.
  • Their official tokenomics clearly say “Subject to change.
  • There’s not sufficient details about the capabilities of the Solana Foundation. And they maintain greater than 10% of the SOL token. And handle a neighborhood reserve of a whopping 38%.
  • Someone detected a mysterious pockets with 11,365,067 SOL. They ended up being an undisclosed mortgage from the Solana Foundation to a market-making agency that offered liquidity on Binance. Those tokens have been ultimately burned, however wow.
  • In December, for six hours, “Solana’s Mainnet Beta network halted new block confirmations, which resulted in a temporary outage.” The purpose was “A validator booted up two instances of their machine and it started transmitting multiple different blocks for the same slot, eventually creating 3 different unconfirmed minority partitions of the network. ” Their excuse was that Solana remains to be in beta, which is honest.

A Quote To Close This

About Solana’s goals, Anatoly Yakovenko informed Techcrunch:

“Everything that we do to make this thing faster and faster results in this better censorship resistance and therefore better markets,” he stated yesterday. “And price discovery is what I imagine is the killer use case for decentralized public networks. Can we be the world’s price discovery engine? That’s an interesting question to ask.”
