Sooner or later, the blockchain section will see custom-made decentralized networks for particular use instances, created en masse, Polygon’s founder Sandeep Nailwal says. This positions his new brainchild, Agglayer, as a way to unify all main blockchain functions.
“Hundreds of custom-built chains”: Polygon founder on subsequent technology of blockchains
Customization of blockchains is the important thing characteristic important for constructing the functions that completely different sorts of shoppers will truly be utilizing. That’s the reason we needs to be prepared for the 1000’s of application-specific blockchains created “within the very close to future,” stated Polygon’s founder Sandeep Nailwal.
My take: within the very close to future we’ll see 1000’s of chains {custom} constructed for very area of interest functions. This customization is vital for creating apps that completely different sorts of shoppers will use.
I argue, each single significant App shall be by itself devoted block-space aka its personal… https://t.co/cuog39VK4D

A few of the appchains will serve actually area of interest use instances. Step-by-step, this course of will equip each significant app with its personal blockchain.
Then, the Agglayer, a brand new cross-network infrastructure protocol backed by the Polygon ecosystem, would be the app that unifies all purpose-made blockchains.
As lined by U.At this time beforehand, Agglayer is poised to play a vital position within the connection between numerous lessons of decentralized networks.
From DeFi to GameFi and RWAs, the Agglayer ecosystem shall be catering to all present and potential cryptocurrency use instances.
What are appchains?
Generally, the Polygon founder’s viewers on X (previously Twitter) agreed on his take concerning the potential of appchains and Agglayer. Some audio system, although, talked about that can make on-chain expertise too fragmented.
Appchain, or application-specific blockchains, are custom-built decentralized networks with adjustable parameters. In contrast to monolithic blockchains (Bitcoin, Ethereum and so forth), appchains may be custom-made to align with the enterprise logics of this or that dApp.
The appchain idea gained traction in 2023-2024, whereas some main decentralized protocols began migration to their very own blockchains, together with Uniswap’s Unichain, dYdX’s dYdX Chain and so forth.
