"Polkadot is a leading example of a multi-chain blockchain that focuses on interoperability."

By BlockStand EU Report, an EU-funded initiative coordinated by the European Digital SME Alliance. 🇪🇺

📰Accelerating Standards for On-Ledger and Off-Ledger Data

Compared Ethereum, Polkadot, Cosmos, Hyperledger Fabric, Chainlink & Quant Network as the ones having interoperability features (cross-chain communication, data exchange, or integration with legacy systems).

Main goals:

- interoperability & sustainability.

- digital identity, governance & security.

- developing agnostic interoperability standards.

In alignment with MICA (Markets in Crypto-Assets), EU Green Deal, European Blockchain Services Infrastructure (EBSI), European Blockchain Partnership (EBP) & ISO standards (ISO/TC 307).

Key Takeaways:

"Interoperability between blockchain platforms and legacy systems remains one of the biggest challenges to widespread blockchain adoption.

The fragmentation between systems limits blockchain's potential, especially in enterprise environments where seamless data exchange is critical."

Why Polkadot is the leader in interoperability?

"Polkadot is suited for blockchain interoperability, where different chains may store varying amounts of data on-chain depending on their specific use cases."

Polkadot enables parachains to communicate with each other and external blockchains.

This interoperability is crucial for applications where different chains manage distinct types of data (e.g., financial transactions, supply chain records, and identity information), all of which may include both on-ledger and off-ledger data."

Where can Polka$DOT improve? The report says:

- less complexity of managing off-ledger data across chains. (unified data integrity verification)

Looking good.
