Blockchains in BOARD?

Unknown

Hi folks,

     Before I try to build my own data model for Ethereum statistics, I thought I would ask if anyone has built one already? ethereum is a cryptocurrency like bitcoin. There are many blockchain projects underway, with many in Switzerland. Has anyone developed a model that can load data from a blockchain? In particular, has anyone developed a model that can load Ethereum smart contract history?

Hi Bob,

 

I myself am a blockchain enthusiast and have done some stuff in my little spare time related to it - and i do agree with you that there is an absolute need to pioneer this field from an analytics perspective.

 

At the moment the 1.0 and 2.0  blockchain generations (bitcoin and ethereum-like) are not really data-friendly, it does require a lot of effort to "scan" the blockchains and most of time there is a need to load indexed data in a sql-like database for better reading.

3.0 and 4.0 blockchains that are coming along do have a better support for data-driven applications and there are some very interesting projects out there.

 

I believe we can create an "Idea" here in the community to consider future support to some of the blockchains, definitely being able to read data from ethereum and eth smart contracts (token splits, transactions, etc) would be an opening to demand for analytics solution for ICOs, blockchain based projects, etc

Thank you Michele Roscelli for sharing your view.  You raise a great point that the blockchain infrastructure isn’t conducive for data analytics yet. It’s more of an OLTP focus than OLAP.

 

There seems to be rapid change happening in this space. I’ll try to craft an idea to encourage support for this growing data source. If I can craft something useful as an inspiration, I’ll be happy to share that too. 

 

If anyone has an interesting question I could use for an inspiration, I’m open to suggestions. Simple stats on price, transaction counts, fees and volume may be a good place to start. A dashboard on top of an interesting smart contract would be something I’d also like to try.

Following up on this, I've added an idea for a Blockchain Datareader and found a slick powershell script to get ether balances for specific wallets. For now, I can use this script to generate a local CSV file to be read into BOARD. Down the road, it would be nice to be able to pull this kind of data directly from a blockchain.
