Scalability Trilemma is a term that originated from Vitalik Buterin, the now-famous creator of Ethereum. The idea, which largely seems appropriate to the current market development for crypto, deals with the 3 most important aspects of a successful crypto project and the challenges they all face; decentralization, security, and scalability.
Vitalik presents that it is probable to attain 2 of the 3, but very difficult to accomplish all three without there being a negative stress on one element or the next.
Former leader of research at Microsoft, Jiaping Wang, who worked with distributed systems and high-performance GPU computing, presents research to resolve the scalability trilemma.
Jiaping Wang said that "...based on research and analysis, the limitations of scalability in blockchain networks are not due to the type of consensus algorithm deployed, but because each single node needs to duplicate the entire network every time a new block is added."
He explained that this built-in over-redundancy is what prevents blockchains like those of Bitcoin and Ethereum from scaling performance and reaching throughput needed to meet the demands of the modern digital economy.
Consensus zones, Wang's solution to the trilemma, can compute parallel transaction processing and a "...distributed workload execution" allowing a blockchain network to process "...up to 100,000 transactions per second and sustain a user base of more than a billion."
With the consensus zones model, Wang said that needless repetition of ledger transactions that slows down current legacy blockchain platforms can be avoided.
“Asynchronous Consensus Zones [which] scales blockchain system linearly without compromising decentralization or security,” the paper reads.
“We achieve this by running multiple independent and parallel instances of single-chain consensus (zones). The consensus happens independently within each zone with minimized communication, which partitions the workload of the entire network and ensures moderate burden for each individual node as network grows.”
The concept has been tested with more than 1000 virtual machines spread across the globe, providing more than 40,000 nodes, and this test provided promising results of significant orders of magnitude in throughput and capacity compared to Bitcoin and Ethereum.
