Blockchain: The Future of Connectivity

Brian Nibley

1. ICON Testnet 


With the latest release of ICON’s testnet, ICON’s SCORE (Smart Contract on Reliable Environment) is now live. SCORE sets the stage for the development of decentralized applications on the ICON platform.

2. Rchain Testnet


The Rchain platform is designed to be scalable while remaining fully decentralized well into the future. As a “complete blockchain platform for distributed applications,” Rchain prides itself on being environmentally friendly by requiring little energy to maintain.

3. Cosmos Testnet


Cosmos is a permission-less network. That means you can build on it without permission, no matter who you are. The cool thing about Cosmos is that it can operate cross-chain with other blockchain platforms.

4. Ultrain Testnet


Ultrain aims to be a sustainable alternative to traditional public blockchain platforms. It’s programmable tech infrastructure, which is based on Javascript, lets you develop DApps within a user-friendly environment.

5. Zilliqa Testnet


Zilliqa is fast, secure, and decentralized. The platform's high throughput means you can develop in an environment absent of high fees, network congestion, or security-related issues.

6. Kyber Network Testnet


Kyber Network is more than just a developer platform. It integrates payment systems, investors, token teams, fund managers, and more. Calling itself the “decentralized liquidity network,” Kyber easily integrates other DApps and leverages the liquidity contributed by them.

7. Celer Network


Celer seeks to use off-chain scaling solutions to scale existing and future blockchains. The team at Celer believe that scalability is the chief issue holding back blockchain mass adoption. And the project intends to scale out to billions of private and secure transactions per second through off-chain scaling techniques.
