What is Solana blockchain?
The most question asked by humans around the world is most probably this. ‘ What time is it!’ right ?. Although, It is so simple to ask and get an answer from people, but not by blocks on any existing blockchain. Except Solana blockchain, Let me explain!
All blockchains out there today, not refer to the time when recording transactions. It means, There is no timestamp within a chain block. Until one day, when someone noticed that nobody is keeping time in crypto and started to build what we call now Solana blockchain.
Caffeine induces fever dream.
The creator of Solana, who was working as a software engineer in Qualcomm was not a big fan of cryptocurrencies, slightly interested in Ethereum. Until one night in 2017 when Anatoly has the fever dream induced by probably caffeine to figure out how to improve cryptocurrency’s blockchains by adding the timestamp to transactions.
Bitcoin longest chain
As you may know, the longest chain is something that happens when two miners try to produce a new block at the same time, This is very common in Bitcoin blockchain, where the blockchain temporarily splits, and the longest of the two blockchains wins. In short, whichever of the two chains produces the new block first becomes the actual bitcoin blockchain. Not very efficient, right!
We could easily prevent the longest chain to happen if only we could tie any transaction to a timestamp, like this every transaction would proceed depending on a regular clock. Well! Google and Intel have already done that in their center servers using a centralized regular clock.
Building a decentralized regular clock is not an easy task! Who would be the time keeper on a decentralized blockchain?
Bitcoin mining algorithm
To build a decentralized regular clock on a blockchain, Anatoly has figured out that we could tweak the same bitcoin mining algorithm or ‘SHA256’ to function as a clock. Combining this with an optimized proof of stake consensus, would make it possible to proceed a huge amount of transactions per second, competing than with the unbeatable Visa network regarding the TPS or the transaction per second.
