Streamr brings US stocks to Ethereum blockchain
While present-day blockchains aren’t nearly scalable enough to ingest big data, we at Streamr are working on ways to make the above vision happen sooner rather than later.
The concept of real-time data flowing into a decentralised system can already be easily demonstrated with the existing Streamr platform and its built-in Ethereum integration.
For now, direct input of data into the blockchain, combined with current blockchain scalability means that the idea can only be explored on a miniature scale, to avoid spamming the Ethereum blockchain and paying excessive gas costs.
Data for all the stocks are reported in a single transaction, in order to avoid spamming hundreds of transactions every 15 minutes.
What effectively happens is that everyone running a full Ethereum node will automatically have fast and verifiable local access to the published data points.
