Best Smart Contract Platforms for Quickbit

Bitcoin is an innovative payment network and a new kind of money. Bitcoin uses peer-to-peer technology to operate with no central authority or banks; managing transactions and the issuing of bitcoins is carried out collectively by the network. Bitcoin is open-source; its design is public, nobody owns or controls Bitcoin and everyone can take part. Through many of its unique properties, Bitcoin allows exciting uses that could not be covered by any previous payment system. Bitcoin transactions are secured by mathematics and energy. Cryptographic signatures prevent other people from spending your money. Energy spent by proof of work (PoW) prevents other people from undoing, rearranging or losing your transactions. So long as you take the required steps to protect your wallet, Bitcoin can give you control over your money and a strong level of protection against many types of fraud.

Polkadot is a blockchain network being built to enable Web 3.0, a decentralized and fair internet where users control their own data and markets prosper from network efficiency and security. Polkadot was founded in 2016 by Gavin Wood, former Co-Founder and CTO of Ethereum. Polkadot’s technology addresses the major issues that have stymied blockchain adoption in recent years. Polkadot’s software development toolkit, Substrate, created by Parity Technologies, makes it easy for blockchain developers to build their own custom, fit-for-use blockchains. Polkadot also enables multiple blockchains to communicate between each other, allows for easy upgradeability, and introduces “shared security”, a plug-and-play network security model that allows developers to focus on the technology and avoid spending time and resources recruiting a set of operators to run a new blockchain.

Ethereum is the community-run technology powering the cryptocurrency, ether (ETH) and thousands of decentralized applications. Ethereum is a technology that's home to digital money, global payments, and applications. The community has built a booming digital economy, bold new ways for creators to earn online, and so much more. It's open to everyone, wherever you are in the world – all you need is the internet. Today, billions of people can’t open bank accounts, others have their payments blocked. Ethereum's decentralized finance (DeFi) system never sleeps or discriminates. With just an internet connection, you can send, receive, borrow, earn interest, and even stream funds anywhere in the world. Today, we gain access to 'free' internet services by giving up control of our personal data. Ethereum services are open by default – you just need a wallet. Stake your ETH to become an Ethereum validator.

Cardano is a blockchain platform for changemakers, innovators, and visionaries, with the tools and technologies required to create possibility for the many, as well as the few, and bring about positive global change. Cardano is a proof-of-stake blockchain platform: the first to be founded on peer-reviewed research and developed through evidence-based methods. It combines pioneering technologies to provide unparalleled security and sustainability to decentralized applications, systems, and societies. With a leading team of engineers, Cardano exists to redistribute power from unaccountable structures to the margins – to individuals – and be an enabling force for positive change and progress. Cardano restores trust to global systems – creating, through science, a more secure, transparent, and sustainable foundation for individuals to transact and exchange, systems to govern, and enterprises to grow.

Connect your smart contract to the outside world. Chainlink's decentralized oracle network provides reliable, tamper-proof inputs and outputs for complex smart contracts on any blockchain. Start building your universally connected smart contract. Use decentralization, trusted nodes, premium data, and cryptographic proofs to connect highly accurate and available data/APIs to any smart contract. Build on a flexible framework that can retrieve data from any API, connect with your existing systems, and integrate with any blockchain, now and in the future. Integrate battle-hardened and time-tested oracle solutions that secure billions of dollars in value for market-leading blockchain projects. Independently monitor and verify Chainlink’s open-source code, the performance of its oracle networks, and the quality of individual node operators.
