This tool allows you to statically analyze a list of Ethereum transactions and determine a safe order of concurrent execution.
The transaction list is specified in the JSON format (see block.json for an example); in particular the json file should contain a list of objects each one with at least the following fields:
type: either “constructor” or “method”; specifies whether this transaction is a contract creation or a method call.called_address: a string containing either the address of the contract which method has been called, or the address in which the newly created contract will be deployed.data: a string containing either the bytecode of the contract or the calldata of the method invocation.
The ouput is written to a file named “output.html”.
The details of the design and the implementation of the library are described in
Tosi Samuele. A Library for the concurrent execution of Ethereum blocks. Master's Thesis. University of Florence, 2021.

The output of the tool is a diagram where each node is a transaction, the number on the nodes represents the index of the transaction in the provided list.
An arc between nodes i and j means that node i must be executed before node j.
JavaScript must be enabled to correctly display the graph.
