TheCardanoblockchaincomes with an innovative Proof of Stake protocol known asOuroboros. The new blockchain transaction verification system’s details were first revealed in a research paper released byIOHKfounder and CEO Charles Hoskinson in April. The company claimed that that new sophisticated Proof of Stake (PoS)aims to:“overcome scalability, efficiency, and composability limitations of the proof-of-work paradigm, which underlies the security of several mainstream cryptocurrencies including Bitcoin.”
Charles Hoskinson Reveals the Details
In atweet datedApril 26, 2018, Charles Hoskinson focused on the importance ofOuroboros. He wrote:
“Of all the papers IOHK Research has written, this one is the most significant. It’s a major advancement for Proof of Stake https://t.co/QNIPonatF6 now PoS has nearly identical properties to PoW. https://t.co/zAP7dSxR3y Welcome to the age of Ouroboros Genesis.”
Hoskinson pointed out that the new mechanism will provide more power efficiency as well as security.He wrote:
“Yeah, we don’t have to use more power than the country of Ireland to have our system run. I didn’t want to copy that one.”
He also suggested thatBitcoin’sextreme power consumption could be magnified multifold as billions of users adopt the platform.
What Does PoS Improve?
The Proof of Work concept is used for verifying transactions on theBitcoinblockchain. PoS comes as an alternative to PoW. It gives users a vote or a stake on the network. This helps in accruing interest in the network in the form of newly minted tokens.
Because of this system, a user becomes an active member of the network. It also helps in reducing power consumption in the network.
As interest in cryptocurrencies is growing rapidly, a global populace using a large blockchain would want a lighter and more power-efficient system like PoS.
The research paper stated:
“Proof-of-stake-based (in short, PoS-based) blockchains aim to overcome scalability, efficiency, and composability limitations of the proof-of-work paradigm, which underlies the security of several mainstream cryptocurrencies including Bitcoin.”
Is PoS Really Better Than PoW?
The problem with Proof of Stake is that the concept is not fully proven yet. PoW remains the most popular verification method to date.
TheBitcoinblockchain, as compared toCardanoand its native coinADA, has been around for longer. It has been subject to more tests, which proves its dominance as a secure consensus and transaction method.
Ouroborosis newer and hasn’t gone through enough trials to be compared toBitcoin’sPoW yet. However,IOHKis confident that their network can represent a more robust transaction verification method.
One interesting thing to note about the blockchain is its interest in bringing the scientific rigor of academics to their organization. Hoskinson and his team fromIOHK,previously, visited theGoogleHQ in London in June and answered questions from Googlers and provided them with insights about distributed ledgers.
