Ethereum: the engine of the database behind the blockchain
As one of the most important and most used decentralized (DAPP) applications on the Ethereum network, understanding how Bitcoin and other best altcoins store their blockchain data are crucial for anyone interested in the cryptocurrency technology. In this article, we will immerse ourselves in the database engine used by Bitcoin and other altcoins to store their blockchain data.
What are the databases?
A database is a collection of organized data stored on a computer or device, allowing users to recover and effectively handle information according to specific criteria. In the context of cryptocurrency, blockchains are distributed books that record transactions in a secure and transparent manner.
How do Altcoins store their blockchain data?
Altcoins, such as Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC) and many others, use various database engines to store their blockchain data. The most commonly used database engine is
Memcached , a popular cache system designed for high performance and high -traffic environments.
Memcached: a key component of Ethereum Blockchain
In 2014, Vitalik Buterin, the creator of Ethereum, implemented Memcached as the default storage engine for Ethereum blockchain. Memcached provides an effective and scalable solution to store large amounts of data, which makes it ideal for the high traffic network.
Other database engines used by Altcoins
Although Memcached is widely used in Ethereum, other popular alternatives include:
* Redis : A powerful key store store that can be used as a database engine.
* MONGODB : A Document Document database which can be used to store blockchain data.
* Riak
: a high performance distributed register system.
Comparison of database engines
| Database engine | Scalability | Performance | Support for SQL queries |
| — | — | — | — |
| Memcached | Top | Very good | Limited support |
| Redis | Good | Excellent | Partial support |
| Mongodb | Good | Excellent | Complete support |
| Riak | Good | Excellent | Partial support |
Conclusion
In conclusion, Bitcoin and other upper altcoins use Memcached as default database engine to store their blockchain data. While other alternatives like Redis and Mongodb are also used, Memcached remains the most adopted solution on the Ethereum network. Understanding the operation of these databases will provide valuable information on the internal functioning of cryptocurrency technology and will allow individuals to optimize their own blockchain storage solutions.
