A series of challenges may be apparent to the reader. As new peers may join or leave the network arbitrarily and anonymously, how can one establish a trust relationship whose standards are high enough that they can support a system? How do you demonstrate ownership of an account? Where to store the accounting ledger to maintain balances and transactions? Despite the magnitude of these challenges, we now have an idea of the basic building blocks of a blockchain for some time through recent innovations and improvements in this sector, making our process of solving the problems much more straightforward. Reaching consensus on which blocks/transactions to accept as valid in a distributed system is challenging. Consensus algorithms have to be resilient to failures of nodes, message delays and corrupt messages, as well as unreliable, unresponsive, or even deliberately malicious nodes. --- # 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://block-convey.gitbook.io/block-convey/block-convey-blockchain-infrastructure.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.
