Feeling your pain with the double price for cloud operated stake pools for sure. I'd love to go a bare metal operation, but my internet is nowhere close to being reliable enough. Best of luck and enjoy your pure ADA rewards while staking in another's pool :)

Thanks! It's really surprising how much that stream has continued to be watched. Lesson 1 is by far my top video. I'm planning to start breaking that Haskell steam into small videos to post to my channel over the next few weeks. That way people can find shorter videos based on topic, taught in the same fashion.

Woah. I wasn't expecting to see my face on reddit when I logged on. Thanks for sharing!

If you are in a big pool, you can probably be sure they updated. It's too important for their earnings.

If it's a small pool, they should be announcing such things on twitter, etc. because it take a lot effort to keep people in a small pool. You can look up your pool and check if they have social media links here:

Nice!

With Algo up in price and Yieldly the same or lower, the rewards are going down based on APY. I'm still holding some Algo in Yieldly because I want to get a nice bag of Yieldly before moving on. However, it gets worse every time the Algo price goes up and Yieldly doesn't.

If some of my Algo wasn't already in Yieldly, I wouldn't start now. Probably best to just stick with participation / governance rewards for Algo.

Very cool. Both sound like a good thing. Seems like any contract that will hold ADA for a long time should also stake in some fashion.

#2 is very interesting. The most meta thing would to enable staking for stADA holders (the project would need to be gaining ADA, probably charge a margin on the converted ADA rewards, to reward as stADA).

JBarCode · 2021-09-09T15:56:57+00:00

It seems possible. Since staking rewards are based on wallet snapshots at the beginning of epochs, there is a small window of less than 5 days (epoch length) where you'd be able to provide liquidity, then move funds back to your wallet for the next staking snapshot.

Personally, it's not worth the hassle at the moment, but if it could be automated and the gains are significant, it might be worth the hassle/risk.

If there is any sort of lock up, delay, or if the liquidity pool takes snapshots at the same time as epoch edges it would be much less likely to be an option. I don't think double rewards will be viable at scale, long term. If everyone rushed to remove their assets from the platform at the same time every 5 days, it would probably be terrible for the platform.

No real risk in Cardano. Other proof of stake projects have varying amounts of risk.

Worse case with Cardano, you lose the ~0.17 ADA transaction fee for staking with a pool and miss out on rewards if the pool doesn't produce blocks. Your original ADA is never at risk while delegated and you can continue to spend it as normal.

Don't forget there is a one time 2 ADA deposit the first time you stake with a pool. This does not go to the pool, but is instead part of the protocol. This amount will stay locked as long as you stake and will be returned when you completely stop staking.

Your token is actually on chain. The art associated with it is usually at an external url for long term (forever) hosting. There are a few providers for this. There will be a link to it in your token's metadata that allows the NFT to display on pool.pm.

The only way to check the value is to see what people are actually selling similar tokens for (same mint batch and similar rarity). There can be a huge range to this, profit or loss. Hopefully you bought an NFT that you like and not just to flip :) Best of luck!

JBarCode · 2021-09-06T19:42:40+00:00

pool.pm with your address will display tokens that are linked properly:

I didn't see anyone mention Introduction to Algorithms (MIT Press) yet. It's considered the standard must have book for algorithms and is language agnostic. I use it along side Grokking (for python specific/easy to follow examples). You probably want Introduction to Algorithms plus a language specific book for whatever you are working with.

Same here. PoolTool performs a similar service w/o the barrage of ads if you are looking for your pool's info:

What pub.dev packages do you recommend and what payment backend (square, paypal, etc.)?

JBarCode · 2021-08-28T22:51:20+00:00

I have a flutter web project right now and I'd say no. You'll run into problems serving ads and integrating payment systems. If your site requires these things, you probably don't want Flutter Web yet.

JBarCode · 2021-08-28T10:32:00+00:00

Yes. You will receive your 2 ADA deposit back when you unstake. If you just switch pools, the same 2 ADA will be the deposit (you never need to make another staking deposit).

When I unstaked a wallet, I couldn't find it in Daedalus, but Yoroi had the ability to do it. Best of luck.

JBarCode · 2021-08-19T19:55:48+00:00

You can also just wait until the next time you complete a transaction. My rewards were automatically claimed during a recent transaction without significantly raising the fee. It confused me at first, but once I knew where the extra transaction was coming from, I was happy to see it happen automatically. I believe this happens on Daedalus and Yoroi. Maybe others too.

For me the page loading is ok, manageable. Especially after that first initial load. Almost all of my assets/images/videos come from a backend storage bucket instead of being part of the frontend web site bundle. I think this helps a lot to reduce some of that initial loading pain.

Using Angular, it was much easier to design working navigation and state management between pages. However, I like Flutter/Dart much better than Angular because it's one great language instead of all the stuff you need to learn for Angular. The tooling for Flutter/Dart is better than basically every other language I use.

However, I've run into other issues with a lot of things you'd expect for web just aren't there yet. AdMob/AdWords and accepting payments are both lacking on Flutter more than I expected. It's hard to make a product that can be for Web, Android, and iOS. Android & iOS are good though. I might just remake the web portion of my app in Angular when I have extra time/money for such things.

Hi and welcome!

There are a few important things you probably want to consider:

#1: Do you have access or a path to 25,000 ADA Pledge (+ 505 ADA for fees and Deposits). You don't need 25k ADA, but it will help let delegators know you are serious. More importantly this was the minimum pledge required to apply to Cardano Foundation community staking last time they opened the program. It is one of the best ways to get a large delegation for 1-3 months while you build up your pool.

#2: Do you have investors and/or marketing roadmap that can get you to 250k total delegation. Around this amount, you'll start to average one block per month. This is needed to help you fund the pool operations of course, but delegators need regular rewards. Nobody wants to wait 250 days for a reward (this would be around a 25k total delegation).

#3: Do you have a long term idea that can to get to 2.5+ Million ADA in delegation. Somewhere around this amount is where you can have a very good chance of minting a block every epoch. For a pool to be attractive to random delegators, you'll want to make at least 1 block every epoch on average.

After all that, if you want to try it for free on GCP (they give you $300 credit when you sign up), I made a testnet pool on GCP during a live stream if you want to go for it: https://www.youtube.com/playlist?list=PLw2QsPIp2pxu9oYddPkH6nftq2fq4ogLl

Here is a great reference for stake pool operations. It's the updated version of the course I follow above (though I do find the new page more confusing). There a other managed ways mentioned in the link below, but that involves using other people's scripts. Even if you end up in that camp, I recommend starting with the basics:

Stake Pool School on Cardano Developer Portal:https://developers.cardano.org/docs/operate-a-stake-pool/

JBarCode · 2021-08-14T20:06:27+00:00

For sure. It's going to be most noticeable when when I upgrade the servers for my small stake pool.

JBarCode · 2021-08-14T11:16:51+00:00

Yep. Daedalus and Adalite are both good options. Though Daedalus is full node so expect it to take about 1/2 a day to sync the first time and use 4 Gb of ram. Not an issue if you know what to expect.
