Interoperability is the ability of a certain network to transfer data and value across other networks. Interoperability is a fairly old concept in computer systems, but I think it is especially important when it comes to blockchains. My reasoning for why I believe that interoperability is integral to the future of this space is due to how much value and liquidity each of the major blockchains carry, and contrary to popular belief liquidity is not gradually concentrating in one blockchain, but rather flowing into various different blockchains.
As time goes by the number of blockchains in this space have increased, and might even continue to increase. The amount of development on each of these alternative blockchains is also increasing, which has been successfully attracting liquidity to them. I doubt this trend of diversified liquidity across blockchains is going anywhere, thus interoperability, and DApps which promote interoperable activities like
pSTAKE (enables interoperable staking) are also going to increase in this space.
Most of this is my personal observations of where the space is heading/headed, and a lot of what I said here is my personal opinion. Although, I am genuinely curious as to what everyone thinks about the diversification of liquidity across various different blockchains, and the implications it has on interoperability.
