Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Fuzzing Around: Better Smart Contract Testing through the Power of Random Inputs
Fuzzing has been around for a while in traditional full-stack development, but a new class of tools is here that can apply fuzzing to smart contract testing in web3. Some of the fuzzing tools include the open source Echidna and MythX.

Smart Contract Audits with ConsenSys Diligence Fuzzing - Fuzzing as a Service
Fuzzing has been around for a while. Defensics and Burp Suite are some examples in the traditional development world. There are also several web3/blockchain fuzzing tools available, such as Echidna and Foundry. However, Diligence Fuzzing is fuzzing as a service and makes everything a little simpler to implement. Which in the end means better audits and more secure contracts. So let’s look into it in more detail.
- Echidna 2.1.1 released with fixes and reduced memory footprint!

Generating and Working With ScriptPubKeys in Bitcoin Transactions
As mentioned previously, ScriptPubKeys are scripts that embody the locking conditions of bitcoins in a Bitcoin transaction. They are a crucial element of a Bitcoin transaction that specifies the requirements that must be met before an unspent transaction output (UTXO) is used. The ScriptPubKey, combined with the Amount, creates an output of a Bitcoin transaction. Like every other script, ScriptPubKeys are made up of operators and data. During the encoding of a transaction, both data and the operands are represented in hexadecimal format. You can find the hex representation for all operands used in Bitcoin Scripts here.
