Chainlink has had some problems lately stemming from the fact that it is on Ethereum. Because Ethereum got congested, Chainlink transactions skyrocketed to up to $20 per transactions and nodes shut down for 6 hours. This may send Chainlink to looking for a new home in order to prevent this from happening again. EOS, TRON, and XRP ledger all have missing features that don’t make them good options. Cardano with Shelley and Goguen coming out soon is the one that needs a look.
