Cardano's Input-output global (IOG) has been a leading blockchain community growing rapidly with its inbuilt blockchain scaling solutions that will finally solve low output speed on users' transactions, the recent Vasil upgrade reduce block transaction fee, increase speed and improve decentralized application (Dapp) development integration for other blockchain to enhance smart contracts incorporation to Cardano's blockchain.
With thousands of users joining the crypto space on daily basis scalability issues will eventually be a major problem that must be tackled in this space, an average block transaction confirmation time can range between 10-20 seconds per a thousand transactions which is very slow when compared to centralized payment system like Master cards that could handle over 1 million transactions per second, (TPS).
Solana one of the fastest blockchains can process 50,000 TPS which does not stand a chance to compete with Master card payment system, on several occasion the blockchain have been crashing due to its low scaling throughput to handle large number of transactions, this also means when a network is congested and as users makes purchase with crypto they have to wait for some seconds for their payments to be confirmed before collecting their order this has to do with scalability problem.
Hydra node solution
Cardano is looking forward to addressing the long scalability issue with its hydra node a layer 2 solution this protocol will reduce and improve storage requirements, and it will optimize fee structure acceptable by validators and users it will be a real-time payment application for real world transaction process, with the hydra node minimal cost will be incurred on a transaction with maximum throughput for processing fast TPS.
Cardano aims to attract decentralized exchange to use the hydra protocol in the future to compete against centralized payment systems scaling by a million TPS.
For blockchain technology to go mainstream scalability problem need to be addressed which is been worked on with the recent hydra layer 2 solution introduced by Cardano blockchain community.
