Appchain or application-specific blockchain is a class of decentralized networks that are only serving the needs of this or that software application. Appchain thesis is built on the top of customizability, flexibility and resource-efficiency narratives. Appchains - not unlike crypto rollups - are being developed by the request of business.

What are application-specific blockchains used for?

To explain what an Appchain is and what it can be used for, we need to review almost all mainstream classes of decentralized applications. Just like crypto ZK rollup projects, Appchains host DeFis, NFT marketplaces, payment gateways, GameFi projects, DePIN and Play-to-Earn applications. With Appchain, day of deployment usually marks a major milestone for this or that crypto protocol.

How to use Appchain explorer?

Just like with major L1 and L2 blockchains - including rollup crypto protocols use to scale - Appchain explorer demonstrates the most recent information about what is happening in the network. Appchain explorers track the data about blocks, transactions, addresses, validators, gas fees, and so on.

What is a rollup in crypto?

A concept of ZK rollup crypto segment made popular in 2022-2023 is basically a mini-blockchain that saves the computational power of its “maternal” chain by processing some data off-chain. For instance, Optimism processes part of its data without sending it to the main network of Ethereum, so do Base, Polygon, and other similar blockchains. As such, to understand what is a crypto rollup, you should imagine a protocol that “rolls up” hundreds of transactions into one and sends it to the main network for verification.

What is the difference between Appchain and rollup?

Appchains work slightly differently from what a rollup in crypto means to the segment. While Appchains don’t necessarily need a “maternal” L1 blockchain, rollups can’t work without being connected to one. As such, it’s easy to explain what is a rollup crypto uses for scaling by knowing the basics of appcoins: rollup can be understood as an appchain connected to other “big blockchain”.
