Searching Blockchain with FreeEed
For example, the speed of write is one block every 10 minutes for Bitcoin, and about one block every seven seconds for Ethereum. Queries, as such, do not exist at all: either SQL or NoSQL-type language is not provided.
Meanwhile, the information stored in Blockchain often needs to be searched. Here are the potential use cases
1. Any kind of eDiscovery with Blockchain needs a full search capability.
2. https://www.securedestate.io/ is an example of Ethereum-based for estate planning, together with legal and financial information.
3. There many examples of similar nature.
From today, such tool exists. FreeEed has been used by lawyers to do eDiscovery and legal review, and by researchers, for all kinds of investigations. It allows you to give it any kind of data as input (see here) and indexes that data for searches. The data can be loose Office files, PST mailboxes, a “load file” produced to lawyers as a result of an eDiscovery request, and as of now, Blockchain.
There is more: we are actively working on FreeEed all the time, adding input formats, processing capabilities, and machine learning. The tool is open source and welcomes new additions. The review part is called “FreeEed Review” and works through the browser.
The back end used to implement text search is Elasticsearch. This means that you can look at the processed data also through the powerful ELK (Elasticsearch, Logstash, Kibana) which are also open source.
