Lynx Cryptocurrency Block Explorer

The Lynx Block Explorer is a NodeJS application that provides real-time blockchain inspection tools to the user. In addition to being able to research discreet transactions, user can inspect blocks and addresses. Additional tools include the top 100 wealthest addresses, the latest blockes mined and the associated miner address, the peers list for the respective node and a realtime market inspector that display the respective order book for various exchanges. A suite of API tools is also exposed for development purposes. Country specific language options are always being added.

History

This code was inspired by the project 'Iquidus Explorer' v1.6.1. Most of this code has been rewritten from that original project.

Requirements

The Lynx Block Explorer requires the respective lynx.conf file to contain the following two lines. The wallet functions are not required and if the wallet functions were compiled into Lynx, they don't have to be enabled for the Block Explorer to function normally.

-daemon 
-txindex

Known Issues

script is already running.

If you receive this message when launching the sync script either a) a sync is currently in progress, or b) a previous sync was killed before it completed. If you are certian a sync is not in progress remove the index.pid from the tmp folder in the explorer root directory.

rm tmp/index.pid

exceeding stack size

RangeError: Maximum call stack size exceeded

Nodes default stack size may be too small to index addresses with many tx's. If you experience the above error while running sync.js the stack size needs to be increased.

To determine the default setting run

node --v8-options | grep -B0 -A1 stack_size

To run sync.js with a larger stack size launch with

node --stack-size=[SIZE] scripts/sync.js index update

Where [SIZE] is an integer higher than the default.

note: SIZE will depend on which blockchain you are using, you may need to play around a bit to find an optimal setting
