Vertical and Horizontal Blockchain Scaling
Does scaling work well with blockchains?
- To be a bit more specific, while horizontal scaling tends to increase the trust or security of a network, it generally results in the overall performance (transaction processing capacity) of the system being degraded.
- On the other hand, vertical scaling generally means making each internal component of a system faster and stronger. This, from the standpoint of a distributed ledger-based system, implies the use of supercomputer nodes. However, the downside to all this is that only a selected few individuals are capable of running such nodes.
How is scaling done
- Vertical scaling is done by improving the efficiency of each individual transaction, whereas horizontal scaling is achieved through increasing the platform’s overall throughput capacity.
What are some of the key points to remember about scalability?
- It is all about centralization vs. decentralization.
- For blockchain platforms, the scalability of a given chain often boils down to the level of decentralization possessed by the network. Highly decentralized ecosystems (such as Bitcoin) are quite slow, whereas networks that are more centralized (like EOS, with its 21 Block Producers) are much faster.
- Therefore, having fewer nodes producing blocks generally makes things faster. However, centralization reduces the interesting properties that blockchains innately possess — namely their resistance to censorship, transparency and overall immutability.
