dependabot-preview[bot] bd950c16ea build(deps): [Security] Bump websocket-extensions from 0.1.3 to 0.1.4 in /docs (#4976 ) Bumps [websocket-extensions](https://github.com/faye/websocket-extensions-node) from 0.1.3 to 0.1.4. This update includes a security fix. <details> <summary>Vulnerabilities fixed</summary> <p><em>Sourced from <a href="https://github.com/advisories/GHSA-g78m-2chm-r7qv">The GitHub Security Advisory Database</a>.</em></p> <blockquote> <p><strong>Regular Expression Denial of Service in websocket-extensions (NPM package)</strong></p> <h3>Impact</h3> <p>The ReDoS flaw allows an attacker to exhaust the server's capacity to process incoming requests by sending a WebSocket handshake request containing a header of the following form:</p> <pre><code>Sec-WebSocket-Extensions: a; b="\c\c\c\c\c\c\c\c\c\c ... </code></pre> <p>That is, a header containing an unclosed string parameter value whose content is a repeating two-byte sequence of a backslash and some other character. The parser takes exponential time to reject this header as invalid, and this will block the processing of any other work on the same thread. Thus if you are running a single-threaded server, such a request can render your service completely unavailable.</p> <h3>Patches</h3> <p>Users should upgrade to version 0.1.4.</p> <h3>Workarounds</h3> </tr></table> ...

Tendermint

Welcome to the Tendermint Core documentation!

Tendermint Core is a blockchain application platform; it provides the equivalent of a web-server, database, and supporting libraries for blockchain applications written in any programming language. Like a web-server serving web applications, Tendermint serves blockchain applications.

More formally, Tendermint Core performs Byzantine Fault Tolerant (BFT) State Machine Replication (SMR) for arbitrary deterministic, finite state machines. For more background, see What is Tendermint?.

To get started quickly with an example application, see the quick start guide.

To learn about application development on Tendermint, see the Application Blockchain Interface.

For more details on using Tendermint, see the respective documentation for Tendermint Core, benchmarking and monitoring, and network deployments.

To find out about the Tendermint ecosystem you can go here. If you are a project that is using Tendermint you are welcome to make a PR to add your project to the list.
