A smart contract isn't so smart. Its probably more accurate to call it an automated contract. All it is, is some programming that when certain conditions are met it does with the money in the contract what it's programmed to do.

I'm probably going to get this myself. Ethereum for Dummies. Its relatively short (as far as technical books go) and looks easy to digest. Think it's probably a real good starting place. https://www.amazon.com/dp/1119474124/ref=cm_sw_r_cp_apa_glt_fabc_ZYET4DJP9528VSN9ZS88

Taken directly from their FAQ: > Why Utopia is not open source?

>We may disclose certain parts of code, specifically related to communication and encryption. However, the decentralized protocol will not be released. Utopia is very knowledge-intensive software. A lot of time, effort and resources went into this product, and we do not want to share all of our know-how as it will result in forks which in turn may result in instability of our main network. Fork will lead to the division of the community, while our intention is the unification of the community of like-minded individuals. The bottom line here is that a lot of software is closed source, and this does not hurt them a bit. In addition, we will audit our code.

A privacy-centered crypto project that isn't open source screams security by obscurity, the worst type of security. At best, they're clueless about privacy and just forked monero and scared of being called out but at worst they're straight-up scammers who no idea how to make a privacy currency. Either way that's a hard pass from me.

> UNLs are just recommended lists, there are many lists and validators can choose their own and where to join.

If you read my post you'll find I already said this and I also said that it doesn't matter because the majority will not bother doing researching and simply trusting the default list, giving Ripple enormous power in practice. That is not a recipe for decentralization at all. To be sustainably decentralized, users must not be able to choose who to trust and who not to trust. Everyone following the rules must be treated equally by everyone. There is no room for special treatment of certain validators, which UNLs are by definition.

>Also XRP is not based on a proof of stake consensus algorithm, the "control" of the supply has nothing to do with the control of the network.

Completely unrelated to what I said in my post so I'm not sure what your point is.

>This can help you https://write.as/panos/why-xrp-is-the-most-misunderstood-cryptocurrency

That didn't help at all because it did nothing to address my argument regarding the UNL. It simply glosses over it in one paragraph, explaining what it is. I already know what it is, that's precisely why I know that it's a grave vulnerability.

good question, it looks like ERC-981 is for fractional ownership of an ERC-721 token, since ERC-721 are non fungible. A real examplle that could use this contract is the cryptokitty that sold for 170k USD worth of eth at the time... since no 2 cryptokittens are alike they are nonfungible, so require ERC-721. utilising ERC-981, you could divide ownership of the kitten with an ERC-20 token. maybe 1700 tokens issued worth 1000k usd each of ETH when issued. why would someone buy it who knows, but someone bought the kitty for that amount.... https://thenextweb.com/hardfork/2018/09/05/most-expensive-cryptokitty/

> An ERC-981 token is also an interface like ERC-20 or ERC-721 which allows splitting ownership of any digital asset. It’s a mixture of ERC-20 and ERC-721 tokens and this interface allow the owner of a fungible ERC-20 to exchange specific units with non-fungible ERC 721 tokens as long as the seller and buyer agree on a value assignment mechanism for each asset.

the football team example in the article you gave would give a better example

> For example – A football league can issue multiple tokens for each team and anyone can buy these tokens and have fractional ownership of the team. Here each team will be represented as ERC-721 non-fungible asset with multiple ERC-20 tokens.

Difference with ERC-1155 is basically batching up ERC-20 and ERC-721 into one transaction, there isnt a erc-20 to erc-721 link of divisible ownership for example. ERC-1155 is pretty useful for ERC-721 for say trading a bunch of game items in one go as opposed to having multiple transactions

I like this tutorial on setting up an ethereum development stack. It focuses on user-facing applications though, not sure if that's what you're intereted in.

I'm finishing off my asp.net core / angular 5 project, then im going to start my dApp idea on ethereum. i made a post here asking for good tutorials as i need to start at a basic level since its a completely different way of coding from what ive seen from examples. also im a windows guy :P seems like most are geared towards linux and macs. itd be nice if there was more info out there for windows solidity devs. if you could provide tutorials in this format, its my preferred:

https://angular.io/tutorial

this tutorial will eventually build you something you can see thats not just a boring hello world app, it gives you the basis to get started with angular 5 and the main concepts you need to get started.

not a fan of videos or books laying out the entire framework / language etc.

I would highly recommend reading Operating System 3 easy pieces. It would help you understand the OS concepts that you are looking for. And keep us posted on the things you are learning.

I recently started Udacity nanodegree for Blockchain Development and so far I really like it. I tried a bunch of other courses but I wanted something that was focused on development. So far I’m happy with this course.

Have a look at the syllabus and see if it suits you.

Check out the $QMN token from the Ducatus network. It's the first DRC20 token onboarded to its blockchain and is sure to bring back the pizza renaissance using web3 technology.

The $QMN is valued at exactly $1 with an unlimited supply that is backed by USDT on the blockchain or USD bank deposits.

I always recommend this book Bitcoin and Cryptocurrency Technologies because I feel that it is sufficiently technical for those who want to get into the weeds, without being overly intimidating.

Thank you. Just read through the consensus and other white papers. For me the consensus was most interesting. I cannot find documentation for how the actual network operates on top. Do you have a link where I can find more on this?

TheNextWeb ran a story labeling Skycoin a scam (link) - due to the missing detail on how the service and mining (outside of the consensus) would do what is claimed.

I went further to browse the git repo for 'skywire', and can confirm this runs a SOCKS proxy service (link). SOCKS is an application layer protocol relying on TCP. There is no path to replace TCP, there is no path to new internet - just proxy service.

There are a couple of big online courses for that now -

1. Udacity BlockChain Nanodegree - 2 terms of 3 months ($1000 per term, not free to audit)
2. Coursera BlockChain Specialization - 4 courses of 4 weeks each (paid certification, free to audit)

Not looked closely. I’m interested in Flow though. Seems like a project that could succeed. Very narrow focus on NFTS and great IP with NBA and NFC onboard.

You can buy it on Kraken and it’s got some interesting tech with 4 different types of nodes all doing different jobs.

You know it does seem like an elegant solution but it's technically different I think. https://www.kraken.com/en-us/learn/what-is-nano just here I see it's delegated proof of stake, which is essentially what hedera will turn into, but maybe I'm just too much of an optimist.

I think we can do better.

>>Within our app, we will engage in non-arbitrary censorship, meaning only horrific or infringing content will be blocked and removed from our content servers. As a U.S. company, LBRY Inc. and management of our app, and other services in our control, will follow all U.S. laws, including the CDA and DMCA. If someone made an app or website using the LBRY protocol in some other country, it would have to follow that country's laws, which aren't necessarily the same as ours. Either app would read the same blockchain though.

Oh a lot is happening. We're really at the tip of the iceberg. I for one am a LP degen... My farms are netting me easily 100 USD a day in dividends across various chains. But there is more to it than just making money.

Most importantly, check out the KlimaDAO project. Their rebase token staking is used to buy carbon sequestration credits, in the process funding reforestation, soil restoration, natural agriculture, etc. Built on Polygon. 1bn+ TVL.

Regen Network on Cosmos is another - a token based on carbon sequestration through natural agriculture. 100m+ TVL and really good peripherals.

Resource Network just launched on Celo. Facile, tethered marketplace for real-world goods and services currently beta testing in Asheville, NC and soon to expand to Austin. 250m+ TVL.

Soooo many more - especially in the emerging fine art + charitable NFT world. But those three are a solid counterpoint to your thesis just by themselves.

It would be impossible to organize a fair society without a government, but it's not good if a government becomes too powerful and not accountable at all by the population or other entities anymore, it's a balance. In a world where 'big brother' has gotten more control through the surveillance that internet offers, blockchain technology counters that power a bit and adds towards the balance.

If you're looking for something to read or listen to then this book might interest you, it talks precisely about the balance of power in society. The Narrow Corridor: States, Societies, and the Fate of Liberty

https://www.cryptocompare.com/coins/guides/what-are-atomic-swaps/

TL;DR: Atomic swaps require coins have both the lightning network implemented and run off of the same cryptographic hash function (Bitcoin/Litecoin/Vertcoin/etc use SHA-256). Non-PoW coins generally don't have a reason to use lightning network, and don't run SHA-256.

That being said, there are a lot of alternatives to atomic swaps coming in the future, so who knows if that will even be a factor.

BGP, OSPF, and others assume everyone is trusted - so you can poison or update data easily. Using blockchain resolves this limitation.

Hello there! This is funny because I was in your same position last week I came here to solve it haha

I'm not sure to be able to answer all your questions but what I can do is to recommend the only wallet that I understand (lol) it's mintMe I found it really easy to use, like it is done for Crypto-rookies and the thing that trapped me here is that it have all coins options, even USD so it makes everything easier for me to convert money and all that.
And about the trading part, it is really quick and secure tho, so... it's cool. Let me know if you like it too ;)

I'd like to add to your points about digital goods.

Valve, the video game company with the largest distribution platform in the world, did got into problem because their digital goods were used for money laundering. They had to make some of their most popular digital items untradable because of this.

IOTA and other minor cryptos are just under the radar. If transaction volume picks up, so will regulators.

Posted the same on r/CryptoCurrency its a shit show over there that sub has really crumbled to what it used to be. Had some interesting answers though. Leaving them here for future lurkers: Amp, colateralization

Inheriti, inheritance solution for cryptos

Amon, somewhat like

Celo, somewhat like

Audius and odyssey kinda Spotify and YouTube with crypto payents

Celo provides a decentralized solution, similar to what you're describing.

It relies upon a randomness beacon to select a set of validators (PoS) to issue these identity credentials. It currently allows a user to prove ownership over a phone number by sending 3 text messages to that number from the matched validators. There's a new feature being added which provides a proof of phone number type (mobile, VoIP, landline).

It's important to note that these identity claims can be used anywhere and are managed by the user, not a centralized company. There's an additional layer of privacy built in that prevents someone from scraping phone number to address pairings.

Oh, since you asked any crypto books too, Mastering Monero gives you a decent understanding of how Monero works without getting into the code, and it's not too long

A lot of the earlier concepts you will be well past but it does go into how the privacy works

This is probably the best one I own. For starters, it has a weird medieval painting for a cover, so you know it's a good programming book.

It doesn't go super in-depth but it wouldn't be a bad first one to get.

Reserve has been in beta in Venezuala for some time: https://play.google.com/store/apps/details?id=rsv.walletapp.reserve&hl=en&gl=US

I don't think it's just people who are interested in blockchain or crypto who are using it, but actual people and business who are trying to find an alternative to their own hyperinflationary currency.
