Education models built on blockchain technology have the momentous challenge of programming their blockchains for powerful performance and efficient productivity to overcome. Given the blockchain’s inherent scalability problem (which results in agonizingly slow communication), decentralized education models have adopted different types of distributed networks to decongest their platforms. In this way, they hope to achieve the quality of communication that’s so crucial to their success. Are their capacities enough for their educational tasks?
The blockchain’s scalability problem
Right now, blockchain technology is where the Internet was at the beginning of the 21st century: agonizingly slow and taking a very long time to upload anything. With the blockchain, this happens because each and every node has to “assent” on the blocks that pass through. Popular blockchain platforms, like Bitcoin and Ethereum, can process around 10 transactions per second on average. In contrast, payment companies like Visa currently process around 5,000 to 8,000 transactions per second on average.
Transactions become more expensive since nodes prefer those with higher prices and the more popular cryptocurrencies raise costs on a highest-price-first-served model.
