While the use of blockchains for more general uses was already discussed in the original paper, it was not until a few years later that blockchain technology emerged as a generic term. A blockchain is a distributed computing architecture where every network node executes and records the same transactions, which are grouped into blocks. Only one block can be added at a time, and every block contains a mathematical proof that verifies that it follows in sequence from the previous block. In this way, the blockchain’s “distributed database” is kept in consensus across the whole network. Individual user interactions with the ledger (transactions) are secured by strong cryptography. Nodes that maintain and verify the network are incentivized by mathematically enforced economic incentives coded into the protocol. ### **LIST OF EXCHANGES EXP IS LISTED ON** * [Bittrex.com](https://bittrex.com/Market/Index?MarketName=BTC-EXP) * [dovewallet.com](https://dovewallet.com/) * [Hitbtc.com](https://hitbtc.com/es/EXP-to-BTC) * [Graviex.net](https://graviex.net/) * [Upbit.com](https://upbit.com/exchange?code=CRIX.UPBIT.BTC-EXP) * [BoaExchange.com](https://boaexchange.com/) --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.expanse.tech/beginner/our-blockchain.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
