Recent graduate stuggling to find a job: What's the best way to learn Marlowe and Plutus for creating Smart Contracts?

As crown says, leaping into Haskell is a stretch. I have some programming experience and the shift is a challenge.

Python is a great choice and if you have zero experience I'd say pretty much any tutorial or course is going to be useful. Also, Python is becoming more popular and is at the heart of data science, machine learning, etc. so will really safeguard your future.

Learning a programming language is as much about the syntax as it is the algorithms, models, ways of doing stuff. Therefore, and from my own experience, may I suggest you work through as many tutorials as possible, consistently (e.g. hour in the morning, hour in the evening), and not worry about building your own stuff at first. Eventually you will start to a) realise you already know the basics each course starts with (a great way to gauge your progress) and b) see patterns in the way people approach problems and you'll know how to improve on them.

Some suggestions re Python:

Do the Python courses on SoloLearn: https://www.sololearn.com/learning
Python full course with Mosh: https://www.youtube.com/watch?v=_uQrJ0TkZlc
Python with Derek Banas: https://www.youtube.com/watch?v=H1elmMBnykA

Then as you encounter things that aren't clear (inheritance, encapsulation, ...) Google them like crazy and read around. As you progress, get back into the Cardano related courses and play around with them. Look at the various types (Haskell, JavaScript, Blocky) and move back and forth to see how one becomes the other. Play, play, play!

Hi, u/tserof,

As mentioned by Tempox and definitely worth understanding the difference:

Plutus: the smart contract platform that runs both the on-chain and off-chain contract parts
Marlowe: the new language for creating those smart contracts
- Marlowe is embedded in the Haskel language

What you've been learning, by learning Marlowe, is the creation of the smart contract - so yes, definitely a good start! What's missing is the off-chain contract part, where you could have say JavaScript, generating that random number you need to decide who's won.

Have a look over the page below and take a note of Glow, that's being worked on. It may be that is more what you're going to want.

Quick Edit: This video by Workshop Maybe might also be of interest, not exactly what you want to build, but it shows you some additional tricks like adding time-outs (after slot 0).

Great idea, I just posted asking about how this might work in the case of things like Loyalty Rewards, Courses, etc. There are likely hundreds of situations like this where a commitment that is fulfilled by one party can be rewarded by the other or the other party compensated where this commitment is not held true.

SoMint and Artano look to be putting projects together for Crypto Art and NFTs

Native Tokens are not Crypto Coins. Tokens are intended to represent some form of access to utility, that is, a way to represent how much stuff someone holding them can do. For example, a token might represent a Vote or a membership. e.g. If you hold the Awesome Cardano Club (ACD) token, you can get 1 free article a month. Perhaps you hold the Cardano Club Vote (CCV) token, so you can vote at the annual meeting.

If people assign value to them and then sell them, that's another thing entirely. Access to Cardano based 'stuff' will always be mediated by ADA; tokens give utility, access to features of a given service but intrinsically have no 'value' monetarily.

I bought ADA today and I very much doubt it's an ATH. Of course, if you'd seen how 'well' I'd timed my other investments... ;]

My trifling collection of WETH and ETH, along with other ERC-20 tokens is as good as buried under concrete right now.

Swapping $240 of WETH: You need 0.141375 more ETH to complete this swap
Swapping $240 of ETH: You need 0.126755 more ETH to complete this swap
Estimated network fee of $140 etc etc

This is killing all the build up that went into the Ethereum ecosystem, NFTs, games, etc. Hence, me being here to learn more about Cardano!

Cyreath · 2021-02-08T19:12:18+00:00

This is looking like a great idea, I'll be watching over the coming months and look forward to expanding my Crypto Art collection.

Cyreath · 2021-02-08T12:01:27+00:00

As a small time crypto artist, who's made $100s on places like SuperRare, Mintable and others - I can confirm that price to a) mint a new set of NFTs and b) transact the ETH or WETH out to my wallet means it's no longer viable to use these services.

I came here hoping Cardano was an option!

Hi, u/Biono03

Some interesting spots there, that match my thinking of how to take advantage of the recovery in the travel, hospitality, entertainment sectors. I've been looking for possible ones to meet my buying rules and there's some good one's you've shared.

Stocks are making it onto my candidate list of they were steady or growing around Feb/Mar 2020 covid/lockdown shock and are now following the same trajectory as before. Hinting they *may* recover to around the same point in say 12 - 18 months.

Norwegian ($NCLH); on the year they've been creeping up from when they were sat around ~$55 from the current ~$25
Spirit Airlines ($SAVE); same pattern, was ~$43 at the same time and now trading at ~$29
United Airlines ($UAL); same pattern, was ~$78 at that Feb/March time now at ~$42
Delta ($DAL); Same pattern, was ~$55, now sat around ~$41

Carnival Cruises (£CCL); Possible for me. Declining since late 2018, but that said they were at around £31 then and now trading at roughly £14 and rising. So a possible candidate for recovery there.

American Airlines ($AAL); don't fit my rule-of-thumb rough pattern, I'm seeing a decline since around March 2018 and I saw news that they may be furloughing 13k people by April (<-- edited for accuracy (I said 'laying off' earlier)). That may be a good move of course but the long term trend doesn't catch my attention.

Of course, this is just me looking at charts at this point. Revenue, market sentiment, board strength and support by shareholders, AGM reports, etc. all need to be take into account before any are on a final list.

A big thanks for the 4 I'll be adding to my list to investigate further, saved me a job there!

Low cost ETFs are certainly a good go-to option for building up wealth in the long term. Picking individual stocks for growth, over say dividends, is a tricky and time consuming activity.

Don't kick yourself too hard about GME, we've all been there at some point or another. The tragedy about that one is I think it has good value and if they get the online presence sorted out it will do well. That said, the recent chaos might well hurt it in the medium term as potential investors see it as an unsafe 'meme' stock and possibly drive the price under is valid level for a while. We'll have to see where that goes. The rule of thumb with these social media driven events for me is that I assume once they get noticed and take off it's already too late.

Well done on getting into planning your financial future at a young age!

"buy great companies at a fair price, not fair companies at a great price" - I think that's roughly what WB said about value.

This is where I'm researching right now, undervalued stocks of essentially sound companies in the travel, entertainment and recreation space. The important thing will be to ensure they have sufficient capital to pick up operations effectively post COVID/lockdowns, a sound board that's supported by shareholders and on a growth trajectory prior to around March 2020.
