Zilliqa (ZIL) is a token developed in the year 2017. Zilliqa is mainly based on the concept of Sharding and primarily aims at improving the scalability of the cryptocurrency networks as in case of Bitcoin or Ethereum. The white paper mentions that the transactions speed would be approximately a thousand times more than that of Ethereum network. Ziliqa is fast, secured and decentralized. Zilliqa’s high throughput means that you can focus on developing your ideas without worrying about network congestion, high transaction fees or security which are the key issues with legacy blockchain platforms. Zilliqa network uses a concept called Sharding where the transactions are grouped into smaller groups and divided among the miners for the parallel transactional verification. Developing smaller groups for transactional verification means the Consensus can be reached faster and hence a higher number of transactions can be processed in a given time frame. The capacity of the network linearly increases in other cryptocurrencies as the number of people joins the network, but in this case, the capacity is increased at a higher variable rate than the number of members joining the network. By incorporating the Sharding Technology, it can completely revolutionize the smart contract functionality too. Ziliqa has few pros as it has a great new technology. Zilliqa is the first platform to use sharding technology. This puts it ahead of the rest of the market. It’s a completely new kind of blockchain designed to solve the problem of scalability. Third-generation platforms like Zilliqa could be the big winners in the future of cryptocurrency. Ziliqa has a strong community. The platform has a lot of fans. The Zilliqa ICO only happened because there was so much demand for it. The Zilliqa ICO also shows that the crypto community is ready to see blockchain technology move to the next phase of its development.
ChainLink is a decentralized oracle service, the first of its kind. When Ethereum went live in 2015, it revolutionized what blockchain could bring to enterprise solution and traditional business. Blockchain was no longer just a medium for new age financial transaction, confined to Bitcoin’s potential to disrupt traditional currency exchange. With Ethereum powered smart contracts, Vitalik Buterin opened up a Pandora’s Box of use cases for blockchain technology. Problem is, per their design, smart contracts can only manage data on the blockchain. Their potential, the ability to provide tamperproof, decentralized applications for uses the world over, is still largely untapped, as many of the smart contract programs built on Ethereum lack a bridge to the real world industries they’re trying to improve. ChainLink’s first component consists of on-chain contracts deployed on Ethereum’s blockchain. These oracle contracts process the data requests of users looking to take advantage of the network’s oracle services. If a user or entity wants access to off-chain data, they submit a user contract (or requesting contract) to ChainLink’s network, and the blockchain processes these requests into their own contracts. These contracts are responsible for matching the requesting contract up with the appropriate oracles. The contracts include a reputation contract, an order-matching contract, and an aggregating contract. The first of these, the reputation contract, is exactly as it sounds: it checks an oracle provider’s track record to verify its integrity. In turn, the order-matching contract logs the user contract’s service level agreement on the network and collects bids from responsible oracle providers. Finally, the aggregating contract accumulates the collective data of the chosen oracles and balances them to find the most accurate result. Unfortunately, the ChainLink team does not offer a roadmap, but a testnet of ChainLink’s services should come sometime within Q1 of 2018. Generally, the project’s general lack of marketing and concrete updates have frustrated community members in the past. Sergey Nazarov, the project’s CEO, is known for a quiet community presence that favors of behind-the-scenes work on ChainLink. The team may not hype their project much, but for what it’s worth, they sacrifice brand marketing in favor of product development–and some community members find this focus to be refreshing. For instance, they’ve established an oracle with Swift Bank, and have a few quiet partnerships with zepplin_os and Request Network. Chainlink has the potential to connect smart contracts with the outside world. It may allow parties to smart contracts to be able to receive external inputs that prove performance and create payment outputs that end users want to receive, such as bank payments. This has the potential to allow smart contract to mimic the vast majority of financial agreements currently available in the market. With the ChainLink Network, anyone can securely provide smart contracts with access to key external data and any other API capabilities, in exchange for financial reward. Although it remains to be seen how the incentive system will operate, there is potential for rewards similar to those available for crypto miners to be available to Node Operators that provide useful data to the Chainlink network.'
