SHA-3-Hashing-Algorithmus - Bergbau, ASIC - Bitcoin

BitcoinSoV

BSoV: The first mine-able, deflationary, open sourced, decentralized cryptocurrency Hedge to act as a Store of Value against the monetary inflation of fiat currency. BSoV is mined using a simple Keccak256 (Sha3) algorithm. There is No ICO, No Pre-mine, and No Governance. This allows for BSoV to be completely decentralized and fairly distributed. With each transfer of BSoV tokens, 1% of the total transaction is burned forever.

How are Ethereum addresses created?

This says that an Ethereum address is basically a Keccak-256 (SHA-3) with some truncation, basically 20 bytes.

Bitcoin by comparison has this nice article: https://en.bitcoin.it/wiki/Technical_background_of_version_1_Bitcoin_addresses
I also found the EIP for checksum addresses, but that of course needs an address to be constructed first: https://eips.ethereum.org/EIPS/eip-55

Waltonchain adds GNU General Public License details to code - BUT does the code contain this?

Waltonchain adds GNU General Public License details to code - BUT does the code contain this?
Dear Crypto community,
Yesterday we saw Waltonchain release their Open Source code which resulted in huge criticism regarding the oversight of removing the original copyright to the original codebase, Ethereum Go, on which it is based.
Following this, the team have now updated the code to show the original copyright:
Image from Github
Source: https://github.com/WaltonChain/WaltonChain_Gwtc_Src/blob/mastep2p/rlpx.go?utm_source=share&utm_medium=ios_app
Github: https://github.com/WaltonChain?tab=repositories

I'd like to say thank you to the community for having such strong opinion on this matter, and for all the subreddit admins that assisted in creating clarity toward this. As a global community we should hold every blockchain up to the same standards, and I am grateful that this was shown in regard to the GNU General Public License.

Now that the issue is resolved, and since Waltonchain is currently a hot topic, I implore all the coders and devs out there to delve deep into the code to see exactly what Waltonchain have released. Not just the modification to the eth codebase, but the additional code. What does the code allow?

What we've been told as a community is that the Waltonchain source code has changes that allows for:
  • Security - DASH X11 - Most cryptographic algorithms used in cryptocurrencies use only one hash function for calculation. There are 11 of them in X11, which provides a higher degree of protection against hackers and scams. Waltonchain has customised the DASH X11 hashing algorithm to fit their purpose.
  • More secure than Bitcoin. The Bitcoin algorithm is SHA-256 is based on a previous secure hash algorithm family of standards, namely SHA-2, the hash functions within the X11 algorithm all successfully made it into the second-round in search for a new, more secure standard — SHA-3. Keccak, the function which won the competition and is therefore the new standard on which SHA-3 is based on, can at the very least be considered more secure that SHA-256.
  • Efficiency — Waltonchain have produced ASICs with the equivalent hashing power of 200GPUs (32–40kW) whilst using only 135W, thus helping the parent chain become decentralised
  • PoS aspect works in tandem with PoW, in that it adds a reduced difficulty based on number of coins held and time between blocks. Effectively the longer coins are held and the longer the time between blocks, the lower the difficulty for mining blocks. This again enhances the power efficiency of the network in its entirety.
  • Fast cross-chain searching via Proof of Labour —PoL enables hash values or indices from sub-chains (child chains) to be synced with the parent chain in a ‘cross chain index mechanism’ to enable fast searches for data via the parent chain.
  • Scalibility — Unlimited scalibility due to child chains; each CC is an independent blockchain (or DAG) using its own consensus mechanism (PoS, PoA, PoW, PoeT, etc) and can store data within itself. The parent chain by nature therefore cannot become bloated.
  • Atomic Swaps — PoL by nature ensures a record of every inter-chain transaction is held, and allows the function of atomic swaps between currencies.

Also to note is that the code has been audited by Knownsec, the same company that audited projects like HPB and NANO.

Lets have an open dialogue and talk about these features of the code - but firstly, do they exist? Hopefully people will approach this with the same enthusiasm as they did yesterday.

EDIT 1st June: A user on the Waltonchain sub has done an analysis which by the looks of it, disproves the initial assessment by many of the 'blockchain experts' in cc that have said the open source code is simply a copy and paste . https://www.reddit.com/waltonchain/comments/bveqea/changeset_goethereum_v171_to_gwtc_v110/
It is interesting to see just how much people love to hate Waltonchain that they spread misinformation either intentionally, or unintentionally, and that it gets the most attention out of any announcement.

FUD Copy Pastas

**Last updated: May 30, 2018: Updated wallet info with release of Trinity.
This 4 part series from the IOTA foundation covers most of the technical FUD centered at IOTA.
https://blog.iota.org/official-iota-foundation-response-to-the-digital-currency-initiative-at-the-mit-media-lab-part-1-72434583a2
Also the official IOTA faq on iota.org answers nearly all of these questions if you want to hear the answers directly.
Purpose of Writing
Since posting FUD is so ridiculously low-effort in comparison to setting the record straight, I felt it necessary to put a log of copy-pastas together to balance the scales so its just as easy to answer the FUD as it was to generate it. So next time you hear someone say "IOTA is centralized", you no longer have to take an hour out of your day and spin your wheels with someone who likely had an agenda to begin with. You just copy-paste away and move on.
It's also worth mentioning IOTA devs are too damn busy working on the protocol and doing their job to answer FUD. So I felt a semblance of responsibility.
Here they are. These answers are too my understanding so if you see something that doesn't look right let me know! They are divided into the following categories so if you are interested in a specific aspect of IOTA you can scroll to that section.
1) WALLET
2) COMMUNITY
3) INVESTING
4) TECHNICAL

WALLET

IOTA was hacked and users funds were stolen!

First, IOTA was not hacked. The term “hacked” is thrown around way too brazingly nowadays and often used to describe events that weren’t hacks to begin with. Its a symptom of this space growing way too fast creating situations of the blind leading the blind and causing hysteria.
What happened:
Many IOTA users trusted a certain 3rd party website to create their seed for their wallets. This website silently sent copies of all the seeds generated to an email address and waited till it felt it had enough funds, then it took everyones money simultaneously. That was the ”hack”.
https://blog.iota.org/the-secret-to-security-is-secrecy-d32b5b7f25ef
The lesson:
The absolute #1 marketed feature of crypto is that you are your own bank. Of everything that is common knowledge about crypto, this is at the top. But being your own bank means you are responsible for the security of your own funds. There is no safety net or centralized system in place that is going to bail you out.
For those that don’t know (and you really should if you’ve invested in anything crypto), your seed is your username-pw-security question-backup email all rolled into one. Would you trust a no-name 3rd party website to produce your username+pw for your bank account? Because thats essentially what users did.
The fix:
Make your seed offline with the generators in the sidebar or use dice. This is outlined in the “how to generate wallet and seed” directly following.
The trinity and carriota wallets will have seed generators within them upon their release.

How to generate wallet and seed

1) Download official trinity wallet here
2) follow the instructions on the app.
3) Do not run any apps in conjunction with the trinity app. Make sure all other apps are completely closed out on your device.

Are you sure a computer can’t just guess my seed?

An IOTA seed is 81 characters long. There are more IOTA seed combinations than atoms in the universe. All the computers in the world combined would take millions billions of years just to find your randomly generated one that’s located somewhere between the 0th and the 2781st combination. The chance for someone to randomly generate the exact same seed as yours is 1 / (2781).
If you can’t fathom the number 27 ^ 81, this video should help:

No questions or concerns get upvoted, only downvoted!

That’s just the nature of this business. Everyone in these communities has money at stake and are extremely incentivized to keep only positive news at the top of the front page. There is nothing you're going to do about that on this subreddit or any crypto subreddit. It's just a reddit fact of life we have to deal with. Everyone has a downvote and everyone has an upvote. But what can be done is just simply answer the questions even if they are downvoted to hell. Yea most people wont' see the answers or discussion but that one person will. every little bit counts.
I will say that there are most certainly answers to nearly every FUD topic out there. Every single one. A lot of the posts I'm seeing as of late especially since the price spike are rehashed from months ago. They are often not answered not because there isn't an answeexplanation, but because regulars who have the answers simply don't see them (for the reason listed above). I can see how it's easy for this to be interpreted (especially by new users) as there not being an answer or "the FUDsters are on to something" but thats just not the case.

Developer's candidness (aka dev's are assholes!)

https://i.redd.it/qb0ik4tgny401.jpg
Lastly and to no surprise, David conducts himself very professionally in this interview even when asked several tough questions about the coordinator and MIT criticism.

IOTA Devs do not respond appropriately to criticism

When critiquers provide feedback that is ACTUALLY useful to the devs, then sure they'll be glad to hear it. So far not once has an outside dev brought up something that the IOTA devs found useful. Every single time it ends up being something that was already taken into consideration with the design and if the critiquer did an ounce of research they would know that. Thus you often find the IOTA devs dismissing their opinion as FUD and responding with hostility because all their critique is really doing is sending the message to their supporters that they are not supposed to like IOTA anymore.
Nick Johnson was a perfect example of this. The Ethereum community was co-existing [peacefully]with IOTA’s community (as they do with nearly all alt coins) until Nick wrote his infamous article. Then almost overnight Ethereum decided it didn’t like IOTA anymore and we’ve been dealing with that shit since. As of today, add LTC to that list with Charlie’s (even admitting) ignorant judgement of IOTA.
12/17/2017: Add John McAfee (bitcoin cash) and Peter Todd (bitcoin) to the list of public figures who have posted ignorantly on IOTA.

A lot of crypto communities certainly like to hate on IOTA...

IOTA is disrupting the disrupters. It invented a completely new distributed ledger infrastructure (the tangle) that replaces the blockchain and solves all of its fundamental problems (namely fees and scaling). To give you an idea of this significance, 99% of the cryptocurrencies that exist are built on a block chain. These projects have billions of dollars invested into them meaning everyone in their communities are incentivized to see IOTA fail and spread as much FUD about it as possible. This includes well known organizations, public figures, and brands. Everyone commenting in these subreddits and crypto communities have their own personal money at stake and skin in the game. Misinformation campaigns, paid reddit posters, upvote/downvote bots, and corrupt moderators are all very real in this space.

INVESTING

How do I buy IOTA

https://medium.com/@fuo213/how-to-buy-iota-the-complete-guide-for-crypto-dummies-e63560caf921

What is the IOTA foundation?

IOTA foundation is a non-profit established in Germany and recognized by the European Union. Blog post here: https://blog.iota.org/iota-foundation-fb61937c9a7e

How many companies and organizations are interested, partnered or actively using IOTA?

A lot, and often too many to keep up with.
https://reddit.com/Iota/comments/7f3dmx/list_of_known_iota_partnerships_corporate/

How was IOTA distributed?

All IOTAs that will ever exist were sold at the ICO in 2015. There was no % reserved for development. Devs had to buy in with their personal money. Community donated back 5% of all IOTA so the IOTA foundation could be setup.

No inflation schedule? No additional coins? How is this sustainable?

Interestingly enough, IOTA is actually the only crypto that does not run into any problems with a currency cap and deflationaryism. Because there are zero fees, you will always be able to pay for something for exactly what it's worth using IOTA, no matter how small the value. If by chance in the future a single iota grows so large in value that it no longer allows someone to pay for something in fractions of a penny, the foundation would just add decimal points allowing for a tenth or a hundreth or a thousandth of an iota to be transacted with.
To give you some perspective, if a single IOTA equals 1 penny, IOTA would have a 27 trillion dollar market cap (100x that of Bitcoin's today)

IOTA is not for P2P, only for M2M

With the release of the trinity wallet, it's now dead simple for anyone to use IOTA funds for P2P. Try it out.

Companies technically don’t have to use the IOTA token

Yes they do
Worth clarifying that 0 iota data transactions are perfectly fine and are welcomed since they still provide pow for 2 other transactions and help secure the network. In the early stages, these types of transactions will probably be what give us the tps/pow needed to remove the coordinator and allow the network defend 34% attacks organically.
But... if someone does not want to sell or exchange their data for free (0 IOTA transaction), then Dominic is saying that the IOTA token must be used for that or any exchange in value on the network.
This is inherently healthy for the ecosystem since it provides a neutral and non-profit middle ground that all parties/companies can trust. If one company made their own token it wouldn’t be trusted since companies are incentivized by profits and nothing is stopping them from manipulating their token to make them more money. Thus, the IOTA foundation will not partner with anyone who refuses to take this option off the table.

All these companies are going to influence IOTA development!!

These companies have no influence on the development of IOTA. They either choose to use it or they don’t.

Internet of things is cheap and will stay cheap

Internet of things is one application of IOTA and considered by many to be the 4th industrial revolution. Go do some googling. IOTA having zero fees enables M2M for the first time in history. Also, if a crypto can do M2M it sure as shit can do M2P and P2P. M2M is hard mode.

IOTA surpassing speculation

IOTA, through the data marketplace and [qubic](qubic.iota.org), will be the first crypto to surpass speculation and actually be used in the real world for something. From there, it will branch out into other use cases, such as P2P. Or maybe P2P use of IOTA will grow in parallel with M2M, because why not?

Investing in a new project barely off the ground

Investing in a project in its early stages was something typically reserved for wealthy individuals/organizations before ICO’s became a thing. With early investing comes much less hand holding and more responsibility on the user to know what they are doing. If you have a hard time accepting this responsibility, don’t invest and wait for the technology to get easier for you. How many people actually knew how to use and mine bitcoin in 2009 before it had all its gui infrastructure?
IOTA is a tangle, the first of its kind. NOT a copy paste blockchain. As a result wallets and applications for IOTA are the first of their kind and translating the tangle into a nice clean user-friendly blockchain experience for the masses is even more taxing.

Why is the price of my coin falling?!

This may be the most asked question on any crypto subreddit but it's also the easiest to explain. The price typically falls when bad things happen to a coin or media fabricates bad news about a coin and a portion of investors take it seriously. The price increases when good things happen to a coin, such as a new exchange listing or a partnership announced etc.. The one piece that is often forgotten but trumps all these effects is something called "market forces".
Market forces is what happens to your coin when another coin gets a big news hit or a group of other coins get big news hits together. For example, when IOTA data marketplace released, IOTA hit a x5 bull run in a single week. But did you notice all the other alt coins in the red? There are a LOT of traders that are looking at the space as a whole and looking to get in on ANY bull action and will sell their other coins to do so. This effect can also be compounded over a long period of time such as what we witnessed when the bitcoin fork FOMO was going on and alt coins were squeezed continuously to feed it for weeks/months.
These examples really just scratch the surface of market forces but the big takeaway is that your coin or any coin will most certainly fall (or rise) in price at the result of what other coins are doing, with the most well known example being bitcoin’s correlation to every coin on the market. If you don't want to play the market-force game or don't have time for it, then you can never go wrong buying and holding.
It's also important to note that there are layers of investors. There's a top layer of light-stepping investors that are a mixture of day traders and gamblers trying to jump in and jump out to make quick money then look for the next buying (or shorting) opportunity at another coin. There's a middle layer of buyers and holders who did their research, believe in the tech and placing their bets it will win out in the long run. And the bottom layer are the founders and devs that are in it till the bitter end and there to see the vision realized. When a coin goes on a bull run, always expect that any day the top layer is going to pack up and leave to the next coin. But the long game is all about that middle layer. That is the layer that will be giving the bear markets their price-drop resistance. That is why the meme "HODL" is so effective because it very elegantly simplifies this whole concept for the common joe and makes them a part of that middle layer regardless if they understand whats going on or not.

TECHNICAL

How is IOTA free and how does it scale

IOTA is an altruistic system. Proof of work is done in IOTA just like bitcoin. Only a user’s device/phone must do pow for 2 other transactions before issuing one of its own. Therefore no miners and no fees. And the network becomes faster the more transactions are posted. Because of this, spamming the network is encouraged since they provide pow for 2 other transactions and speed up the network.

IOTA is centralized

IOTA is more decentralized than any blockchain crypto that relies on 5 pools of miners, all largely based in China. Furthermore, the coordinator is not a server in the dev’s basement that secretly processes all the transactions. It’s several nodes all around the globe that add milestone transactions to show the direction of the IF’s tangle within the DAG so people don’t accidentally follow a fork from a malicious actor. Anyone with the know-how can fork the tangle right now with a double-spend. But no one would follow their fork because the coordinator reveals which tangle is the legit IF one. If the coordinator wasn’t there (assuming low honest-transaction volume), there would be no way to discern which path to follow especially after the tangle diverges into forks of forks. Once throughout of honest transactions is significant enough, the “honest tangle” will replace the coordinated one and people will know which one to follow simply because it’s the biggest one in the room.
Referencing the coordinator is also optional.
Also, if you research and understand how IOTA intends to work without the coordinator, it’s easier to accept it for now as training wheels. I suggest reading pg 15 and on of the white paper analyzing in great depth how the network will defend different attack scenarios without a coordinator. For the past several months, IOTA foundation has been using St Petersburg college’s super computer to stress test IOTA and learn when they can turn the coordinator off. There will likely be a blog about the results soon.
This is another great read covering double spends on IOTA without a coordinator: www.tangleblog.com/2017/07/10/is-double-spending-possible-with-iota/
This too: http://www.reddit.com/Iota/comments/7eix4a/any_iota_guru_that_can_explain_what_this_guy_is/dq5ijrm
Also this correspondence with Vitalik and Come_from_Beyond https://twitter.com/DavidSonstebo/status/932510087301779456
At the end of the day, outstanding claims require outstanding evidence and folks approaching IOTA with a “I’ll believe it when I see it” attitude is completely understandable. It’s all about your risk tolerance.

Can IOTA defend double spend attacks?

99% of these “but did they think about double spend attacks?” type questions could just be answered if people went and did their own research. Yes of course they thought about that. That’s like crypto101…
