Blockchain Advances: Sovereign Currencies On-Chain, Protocol Upgrades, NFT Trading Enhancements

What Shipped

Welcome to your latest update on the blockchain and cryptocurrency space, where innovation continues to move at a rapid pace! Today, we’re focusing on some exciting developments involving Ripple, Stellar, Hedera Hashgraph, Flare Network, and XDC Network, all of which are making strides to improve how digital assets and blockchain technology serve everyday users and businesses.

One standout project is Etherfuse, which aims to bring 100 sovereign currencies—official national currencies like the US Dollar or Euro—onto the blockchain. This means these real-world currencies could be represented digitally on a blockchain, making cross-border payments faster, cheaper, and more transparent.

Stellar, a blockchain known for its focus on financial inclusion and cross-border payments, recently released its Protocol 24 Upgrade Guide. Protocol upgrades are like software updates that improve the network’s security, speed, or features. Protocol 24 brings important improvements to make transactions more efficient and secure for everyone using the Stellar network.

Additionally, Stellar celebrated its i³ Awards 2025, recognizing outstanding projects and developers building on its platform. These awards highlight the growing ecosystem of apps and services that make blockchain technology more accessible and useful.

On the data front, Chainlink—another major player in blockchain infrastructure—released its Q3 2025 Quarterly Review and announced the launch of DataLink, a new tool designed to bring institutional market data directly onto blockchains. This helps smart contracts (self-executing contracts coded on blockchains) access real-world information securely and reliably.

Finally, Ripple’s XRP Ledger is exploring new possibilities for trading NFTs (non-fungible tokens, which are unique digital collectibles) directly between users through a proposed “Batch” amendment. This could make NFT trading faster and more efficient.

Why It Matters

These developments show how blockchain technology is evolving beyond simple digital currencies to become a foundational technology for global finance and data sharing. Here’s why these updates are important:

Bringing sovereign currencies on-chain: Etherfuse’s goal to digitize 100 national currencies can revolutionize international payments by reducing costs and delays. Imagine sending money overseas instantly with minimal fees.
Network upgrades like Protocol 24: Regular improvements ensure blockchains remain secure, fast, and scalable, which is crucial for mass adoption.
Recognizing builders: The Stellar i³ Awards encourage innovation by spotlighting developers who create useful blockchain applications.
Reliable data for smart contracts: Chainlink’s DataLink helps smart contracts make decisions based on trustworthy, real-world information, expanding their usefulness.
Innovations in NFT trading: Ripple’s proposed batch trading could reduce costs and speed up NFT transactions, making digital collectibles more accessible.
