Blockchain and big data belong to different eras. Yongxin Big Data believes that blockchain is another technological revolution after big data. Big data is often used to describe data sets that are large and complex enough to be difficult to process in traditional ways. The information data that blockchain can carry is limited, and it is still far from the "big data" standard. However, with the development of the sharing economy, big data and blockchain have begun to engage in CP again. Two mysterious technologies and Their relationship has become confusing in various speeches and public events.
Big data needs to cope with massive and rapidly growing storage, which requires the underlying hardware architecture and file system to be much more cost-effective than traditional technologies and to be able to flexibly expand storage capacity. Google's GFS and Hadoop's HDFS lay the foundation for big data storage technology. In addition, another challenge that big data poses to storage technology is the adaptability of multiple data formats. Therefore, the underlying storage layer of big data is not only HDFS, but also storage architectures such as HBase and Kudu.
Blockchain is a technology that completely changes the way the Internet operates. The technology works by creating a series of data records, where each new record resides in a block and points to the previous record. The term "blockchain" comes from this structure of connected blocks of data.
Blockchain technology enables distributed ledger systems, making records more transparent. The technology uses encryption to protect user information, making the split ledger system nearly impossible to hack. Blockchain technology is not only the backbone technology of cryptocurrency, but also has several other uses.
Cryptocurrency exchanges on blockchain networks can be centralized or networked. Decentralized cryptocurrency exchanges are nearly impossible to hack because there are multiple nodes supporting the system. Blockchain technology makes it possible to share content peer-to-peer without the need for a middleman platform. No matter what content is shared via the blockchain network, the user retains ownership of the content unless the user sells it to someone else. Personal information is extremely secure and protected by private key encryption.
Blockchain is a non-tamperable, full-history distributed database storage technology. The huge blockchain data collection contains the entire history of each transaction. With the rapid development of the application of blockchain technology, the scale of data will increase. Increasingly, the data integration of blockchains in different business scenarios will further expand the scale and richness of data.
Big data is mainly about managing massive amounts of data, while the core of blockchain is to achieve high security and reliability of data without centralized intermediaries. Therefore, blockchain and big data do not conflict with each other, nor will they replace each other. They are completely different solutions for data in different scenarios.
