No matter the blockchain, individual blocks are limited in the amount of information they can hold; so when blockspace becomes limited, transaction fees increase.

As Ava Labs COO Kevin Sekniqi puts it: “Chains are only cheap as long as the blockspace has not been filled up completely — once blockspace gets filled up completely, it becomes expensive.”

In this episode of the Scoop, Sekniqi explains how Avalanche — the proof-of-stake blockchain Ava Labs launched back in September 2020 — utilizes ‘subnets’ to tackle the problem of blockchain scalability, and how subnets compare to other scaling solutions.

As Sekniqi explains, existing validators of the Avalanche blockchain are able to deploy new subnets, and choose the rules of how they operate:

“The simplest way to describe subnets… is a subset of the Avalanche validators coming together and agreeing to do something.”

For example, the validators of a new subnet could choose to optimize the specifications of the new chain for a specific application, or validators could choose to require users to undergo KYC before interacting with the new subnet.

Whereas an Avalanche subnet could theoretically be run with just a single validator, popular scaling solutions on Ethereum rely on the entire validator set of the base chain to process transactions.

Sekniqi argues that this approach is likely unnecessary, and creates “extreme overhead that you don’t really want.”

Instead, Sekniqi believes the number of validators securing a chain should scale organically alongside its value:

“​​If there's a lot of activity and it truly is a very valuable chain, more and more people will start validating that chain because there are incentives… and so [security] scales up as the value is built upon it.”

During this episode, Chaparro and Sekniqi also discuss:

  • Crypto's highly reflexive nature
  • Blockchain gaming, and gaming optimized subnets
  • The need for industry-wide regulation
