Hi there! If you have any feedback on:

• Community rules
• Categories structure / naming
• Forum configuration
• This list

Then this is the best place for us to read it

Thanks!

Hi! @martriay @tinchoabbate @elopio @fiiiu I was thinking it would be nice to have a place to discuss about security, audits, research, ethernaut. Not sure how it could be structured yet but we can work on something.

[fiiiu]

Ian, thanks for suggesting! I like the idea, maybe a category for Zeppelin Research?

We need to keep in mind that there are several places already where security discussions are taking place, so as not to duplicate efforts…

Where would that be?

Hi, I been thinking it could be a good idea to have an ethernaut category. There, solutions could be posted, bugs reported, questions answer and new level proposed.
Of course, there is the GitHub issues page, so maybe it could be overdoing it. But for someone who is learning it could be of use.

[fiiiu]

I was thinking maybe https://forum.ethereum.org/ or https://ethereum-magicians.org/… but it’s true that those are Ethereum-specific…

In any case, I think we should do it here! (under either Security or Research)

FYI, it looks like the SSL cert for your slack might be out of date. (I see now that you’re deprecating the Slack, but I didn’t know that when I tried to access it.)

[martriay]

Hi @nmclrn, thank you very much for the heads up! As you said, we’re deprecating it but that doesn’t mean we don’t want to make our community safe, so will fix it right away

Also, feel free to introduce yourself to the community in the intros thread!

[spalladino]

Thanks for the heads up @nmclrn! It should be fixed now

I would suggest a discord channel, it can be good for short form communication and quite potentially increase the community engagement.

[frederickalcantara]

I would also suggest a having a site or a page in which there is a more formal set of articles in which the team could write about Zeppelin research, updates on the tech. Another suggestion that would be more of a back burner idea is that we could have a smart contract tutorial similar to what Crypto Zombies has.

Hello @frederickalcantara, thank you very much for your thoughts

Are you aware of our Telegram channel?

I would also suggest a having a site or a page in which there is a more formal set of articles in which the team could write about Zeppelin research, updates on the tech.

Would this be different from our #general:guides-and-tutorials category and our blog? (actually we have two but we’re merging them soon)

Another suggestion that would be more of a back burner idea is that we could have a smart contract tutorial similar to what Crypto Zombies has.

I know you’re familiar with Ethernaut, which is our game-tutorial. What kind of things you like abourt Cryptozombies?

How to create an upgradeable smart contract using ZeppelinOS — example of fixing smart contract vulnerable to underflow/overflow attacks

Post originally written by @paulinablaszk on medium (Apr 23, 2019) In this tutorial we will use ZeppelinOS to fix smart contract vulnerable to underflow/overflow attacks. Firstly we will prepare our environment and create the upgradeable smart contract with some bug and test it. Then we will update the code, upgrade the smart contract and finally, we will check if it is safe. [image] Upgradeability in smart contracts In principle smart contracts are immutable. Once deployed to the network,…

[martriay]

I don’t see any answer nor failed attempts, could you try again?

Hi @oxuw4 the only post I can see of yours is about asking for examples of ERC20 and crowdsales.

Where are the real good ERC20-Token/Crowdsale examples?

Hi, in order to list real live example code for ERC20-Token and Crowdsales at a talk about Smart Contracts I’m looking for such projects? Who can recommend me the real GOOD examples out there (and not all these broken stuff that can be found with Google and/or GitHub from <= 2017 that also is mostly outdated and can’t get compiled any more with latest solidity compiler versions). They should also base on Openzeppelin. Any examples are much appreciated! Thank you all in advance.
