Losses from smart contract bugs are going down, while losses from counterparty risk and custody are going up.

"Throughout the year people ask “How can we support Ape?”

We always say “wait for the next Gitcoin round so you can double your impact”

Today is the day.

The @gitcoin Developer Tooling and Libraries is now live!

Every cent donated is given to our devs so we can continue to make you more free, open source, and moddable tools for you to create the project you always wanted.

Obviously you don’t have to, all our tools will be free forever, but this helps massively to maintain the quality you expect from us.

Join here, feed the Apes, and double your impact:

Ape is the number one smart contract development framework for Python.

Few hours left to support them on Gitcoin.

TIL Python hash() function is not stable between Python runs, but not even in the multiprocessing.

Python hash() is non-deterministic to avoid dictionary stuffing attacks in web servers https://thepythoncorner.com/posts/2020-08-21-hash-tables-understanding-dictionaries/

However Python hash function seems to be also unstable in multiprocessing: in certain scenarios subprocesses generate different hashes.

For persistent hashes (cache) and communications use hashlib.md5() or hashlib.sha()

How are we making Farcaster easier to understand for new people

1. We're still considering rebranding Warpcast (back) to Farcaster. If we do that, will have an FIP. It will be controversial, but initial feedback from most developers actively building on the protocol is they are a supportive (with the goal of increasing users on the protocol). To be clear: this is not final /decided.

2. We rebranded frames to mini apps. This is a more literal name and in line with other popular ecosystems like Telegram. This is easier to understand for new developers.

3. We're gradually deprecating warps. We here this feedback a lot—what are warps and why do I need them—and moving most of the functionality of warps to USDC is much simpler (as well as being more composable).

4. We're working on cheaper / free sign ups. A lot of potential good new users churn at the $3 to sign up screen. Our goals are to 1) make it cheaper at the protocol for other apps and 2) free on Warpcast with a verification (we pay the protocol).
