Arweave aims to make information permanence sustainable. Arweave describes itself as a new type of storage that backs data with sustainable and perpetual endowments, allowing users and developers to store data forever. As a collectively owned hard drive that never forgets, Arweave aims to allow users to remember and preserve valuable information, apps, and history indefinitely. By preserving history, it prevents others from rewriting it.
ChainLink (LINK) is the native currency of the ChainLink platform. It represents an ERC-20 token is listed on multiple exchanges paired against major cryptos. At the time of writing, you can trade LINK against the fiat USD currency on Coinbase Pro.
Smart contracts are not able to access data on their own. Since connecting these contracts to data via node is deemed as a point of failure, using a decentralized service could be a solution.
Therefore, the ChainLink project sees its mission in the integration of the off-chain data into smart contracts through a reliable decentralized oracle network. LINK tokens hit the market in 2017 and the currency quickly made its way to the top 50 cryptocurrencies by market cap. Later it reached the top 20. ChainLink partners with a large banking network SWIFT.
