Ethereum vs BigchainDB: What are the differences?
Developers describe Ethereum as "Open source platform to write and distribute decentralized applications". A decentralized platform for applications that run exactly as programmed without any chance of fraud, censorship or third-party interference. On the other hand, BigchainDB is detailed as "A database with blockchain characteristics". It is designed to merge the best of two worlds: the “traditional” distributed database world and the “traditional” blockchain world. With high throughput, low latency, powerful query functionality, decentralized control, immutable data storage and built-in asset support.
Ethereum and BigchainDB can be categorized as "Blockchain" tools.
Ethereum is an open source tool with 4.73K GitHub stars and 1.63K GitHub forks. Here's a link to Ethereum's open source repository on GitHub.
