Best Smart Contract Platforms for KardiaChain

Ethereum is the community-run technology that powers the cryptocurrency, Ethereum (ETH), and thousands of decentralized apps. Ethereum is a technology that allows for digital money, global payments, as well as applications. The community has created a vibrant digital economy, new ways for creators of online income, and many other benefits. It's accessible to anyone, anywhere in the world. All you need is the internet. Today, billions cannot open bank accounts and others have their payments blocked. The Ethereum decentralized finance system (DeFi), never sleeps nor discriminates. You can send, receive and borrow money anywhere in the world with an internet connection. We can now access 'free' internet services without having to give up our personal data. Ethereum services are available by default. You only need a wallet. These services are free and easy-to-set up. They can be controlled by you and work without your personal information. Stake your ETH to become an Ethereum validator. Staking is a public good for the Ethereum ecosystem. You can help secure the network and earn rewards in the process.

Connect your smart contract with the outside world. Chainlink's decentralized Oracle network provides reliable, tamperproof inputs and outgoings for complex smart contract on any blockchain. Start building your universally connected smart contracts. To connect high-quality and accessible data/APIs to any smart contracts, use decentralization, trusted data, premium data, cryptographic proofs, and trust nodes. A flexible framework can be used to retrieve data from any API, connect to existing systems, and integrate any blockchain, both now and in the future. Integrate battle-tested and proven oracle solutions that have secured billions in value for leading blockchain projects. Independently verify Chainlink's open source code, performance of its oracle network, and quality of individual node operator.

The blockchain development platform. Neo offers a full set of features right out of the box but doesn't limit you. Native functionality gives you all the infrastructure needed to build complete decentralized apps, while advanced interoperability lets you harness the power and potential of the global blockchain ecosystem. Neo's unique dual token model separates utility and governance. NEO token holders can participate in governance and are the owners of the network. Passive distribution of the network utility token GAS is also available to NEO holders - No staking required. Voting participation earns you more GAS rewards. GAS can be used to pay network fees, smart contract deployments and in dApp purchase.

Polygon (previously Matic Network), is a protocol and framework that allows you to build and connect Ethereum-compatible blockchain networks. Although Ethereum is the preferred blockchain development platform, it has its limitations. Polygon - A protocol and framework for building and connecting Ethereum compatible blockchain networks. Preset blockchain networks can be deployed in one click. A growing number of modules are available for the development of custom networks. Interoperability protocol to exchange arbitrary messages with Ethereum or other blockchain networks. Modular and optional security as a service. Modules for adaptors to enable interoperability with existing blockchain networks. Polygon brings together the best of Ethereum, sovereign and other blockchains in an attractive feature set. For developers.
