Full Alu plate, built with Gateron Black Inks and Durock stabs both lubed with 205g0. Amazing condition, I am the first owner so everything will be shipped in Original packaging. Does not come with USB mini cable or the Keycaps.
Trade or 525 Euros if I find a TMOv2
Black plastic case built by KBDfans with an Alu plate and stock Gateron Black silents (although the switches aren't too quiet). Comes with original Keycaps, but no USB Mini.
Was overclocked. Used for render work for 2 years. Works perfectly, but is a little dusty.
I've got +- 600 Euros to offer or a PC Canoe (plus paypal) for the TMO and GMK. Would prefer a single seller, but please send through your offers :) I can cover shipping in the EU, but buyer pays PP fees please. I would prefer EU offers, just because international shipping and import taxes cost a liver right now. Comment and then PM :)
@BitcoinCom: "Felicitaciones a CoinEx por convertirse en el mayor mercado de criptomonedas en el mundo en términos de volumen de comercio. 1,46 billones de dólares (...) No es coincidencia que CoinEx esté usando Bitcoin Cash como moneda base para sus pares de intercambio"
BitLicense isn't bitcoin regulation, it is a de facto bitcoin ban, coupled with the introduction of a whitelist-based altcoin run by governments but utilizing the bitcoin blockchain.
It's tough to accept, but we might be facing the first attempt at seriously enforcing a total ban on all bitcoin transactions. The fact that it will be enforced simultaneously with the introduction of a government-controlled NYCoin just makes it even more dangerous. This is probably the first time bitcoin has ever been in real danger of being supplanted by something else. NYCoin might become USACoin, which might then merge with ChinaCoin and EUCoin to become something I imagine will commonly be called WhiteCoin - a global surveillance based currency with a worldwide monopoly on trading legal goods and services. I think it is important that we realize that the BitLicense is what can best be described as an "attack" - a deliberate attempt to hurt bitcoin users - and we should fight back with everything we have. The fact that Ben Lawsky tricked us into thinking his main concern was to ensure a good environment for startups shows that the people attacking us are not holding back, but are willing to use any tricks necessary to crush us. I can't think of much that can be done right now, but my best bet is that we need to try to attack the value of this WhiteCoin wherever it pops up, NYCoin being the first. It will be tough, and a boycott will not be enough because this is the coin that big money will be investing in. Perhaps it will be possible for bitcoin users to force miners to choose between mining transactions for one of the two coins, thus making sure that as long as bitcoin is the dominant digital currency by transaction fees, whitecoin transactions will be really slow. We can be absolutely certain the opposite would happen instantly should whitecoin ever become the dominant currency.

MicroStrategy's $425M BTC investment thesis - "buy something that can either get cut in half or 10x"
Amidst all of the DeFi volatility, drama and excitement, Bitcoin has started to seem rather boring. Its price is more or less flat to where it was a year ago and you can’t even farm Yams with it. While some have started to view Bitcoin as a useless digital rock, someone did find an interesting use case for it. This week, more details surfaced around how MicroStrategy CEO Michael Saylor convinced the board of a publicly traded company to allocate nearly all of the company’s $500M cash position to bitcoin. Michael Saylor Saylor graduated from MIT in 1987 and founded Microstrategy at the age of 24. MicroStrategy is a “Business Intelligence” company, which basically creates software that allows companies to use their own data to drive decision making. Interesting side note - Saylor, like any good 90’s internet entrepreneur, also bought a bunch of internet domains and was the guy who ultimately sold Voice.com to Block.One (EOS) for $30M. MicroStrategy’s’ $500M Problem To most people, having $500 million in cash doesn’t sound like a problem. Up until recently, it wasn’t for large corporations either. There was a time before the ‘08 financial crisis when the risk free rate of return on cash was 5% a year. This means a company could sit on $500M, earn $25M a year for doing nothing, and have cash on hand for a rainy day. Fast forward to today, when the risk free rate of return has plummeted to 0.69% due to loose fiscal policies (money printer go BRRRR) alongside inflating asset prices, and it’s a different story. In Saylor’s own words, “we just had the awful realization that we were sitting on top of a $500 million ice cube that’s melting.” Cash is Trash So what’s a corporation to do with a $500M melting ice cube? It turns out it’s not that easy to unload half a billion dollars in a short amount of time. You could buy back half a billion of your own company’s shares. For a company like MSTR, Saylor estimated that would take 4 years. Time MiscroStrategy didn’t have. You could buy real estate. However, commercial real estate prices have collapsed post COVID while property owners still believe their assets are worth what they were in January. In other words, good luck getting a fair market price. You could buy blue chip equities. Amazon, Apple, Google, Facebook. However, your risk is symmetric. They can each fall 50% just as easily as they can go up 50%. That left Saylor with silver, gold, Bitcoin, and other alternative assets. A move the company announced it was exploring on a July earnings call. A Bold Purchase Saylor ultimately wanted something that could either get cut in half, or go up by a factor of 10. An investment akin to what buying Amazon or Apple in 2012 was. In other words, asymmetric risk. As a student of technological history, Saylor observed that the winning strategy over the last ten years has been to find some kind of “digitally dominant network” that dematerializes something fundamental to society. Apple dematerialized mobile communications. Amazon dematerialized commerce. Google dematerialized the process of gathering information. Something Saylor noted was common to all recent 10X opportunities is buying when they’ve achieved $100B+ marketcaps and are ten times the size of their next biggest competitor. As Bitcoin is the dominant digital network dematerializing money that’s 10x the size of any cryptocurrency competing to be a store-of-value (not counting ETH here), it fit the bill. Making the purchase With the thesis in place, the next thing Saylor had to do was get everyone at MicroStrategy to sign-off on the unorthodox decision. To do this, he simply made everyone go down the same Bitcoin rabbithole that most people in the industry have gone down. He made everyone at the company watch Andreas Antonopoulous videos, read The Bitcoin Standard, watch Eric Vorhees debate Peter Schiff and listen to Pomp and NLW podcasts. With no strong detractors, MicroStrategy turned to execution. They first put $250M to work purchasing 21,454 BTC in August and another $175M (16,796 BTC) in September for a total $425M and 38,250 BTC. What’s fascinating is that MicroStrategy was able to open such a large position without really moving the market or anyone even taking notice. This speaks to just how liquid of an asset BTC has become. To acquire the September tranche of BTC, Saylor disclosed that they traded continuously for 74 hours, executing 88,617 trades of .19 BTC every 3 seconds. One for the history books Skeptics noted that shares of MSTR have been on the downtrend since 2013, as the real reason behind MicroStrategy’s bold move. Regardless, the move has interesting implications for the company’s shareholders. As TBI observed, MicroStrategy is now both a software company and with ⅓ of its marketcap in Bitcoin, a pseudo Bitcoin ETF. At the time of writing, MSTR is up 20% on the week. Only time will tell if history looks back on this move as a brilliant strategic decision or a massive corporate blunder. In the short term, it scores a massive win for Bitcoin’s digital gold investment thesis. Billionaire hedge fund manager Paul Tudor Jones is in. A publicly traded corporation has made Bitcoin it’s primary treasury asset. As CFOs and fund managers around the world undoubtedly take notice, one has to wonder, who’s next? PS - I based a lot of this article on Pomp’s interview with Michael Saylor, which I recommend giving a listen. Original article Source

Quebecoin sera lancé d'ici une semaine. Une nouvelle crypto-monais utilsant les dernière technologies. QBC "promets" être d'abord disponible pour les résidents du Québec, et ce, en conservant une "pré-extraction" de 50% du total des pièces. Le plan actuelle est de remettre 1/5 de cette pré-extraction au résident du Québec à chaque deux ans, donc sur une période de 10 ans. Visitez http://www.qbc.io/fr.html#contact Des question?

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments. It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Limited Supply - There will only ever be 21,000,000 bitcoins created and they are issued in a predictable fashion, you can view the inflation schedule here. Once they are all issued Bitcoin will be truly deflationary. The halving countdown can be found here.
Open source - Bitcoin code is fully auditable. You can read the source code yourself here.
Accountable - The public ledger is transparent, all transactions are seen by everyone.
Decentralized - Bitcoin is globally distributed across thousands of nodes with no single point of failure and as such can't be shut down similar to how Bittorrent works. You can even run a node on a Raspberry Pi.
Censorship resistant - No one can prevent you from interacting with the bitcoin network and no one can censor, alter or block transactions that they disagree with, see Operation Chokepoint.
Push system - There are no chargebacks in bitcoin because only the person who owns the address where the bitcoins reside has the authority to move them.
Low fee scaling - On chain transaction fees depend on network demand and how much priority you wish to assign to the transaction. Most wallets calculate on chain fees automatically but you can view current fees here and mempool activity here. On chain fees may rise occasionally due to network demand, however instant micropayments that do not require confirmations are happening via the Lightning Network, a second layer scaling solution currently rolling out on the Bitcoin mainnet.
Borderless - No country can stop it from going in/out, even in areas currently unserved by traditional banking as the ledger is globally distributed.
Portable - Bitcoins are digital so they are easier to move than cash or gold. They can even be transported by simply memorizing a string of words for wallet recovery (while cool this method is generally not recommended due to potential for insecure key generation by inexperienced users. Hardware wallets are the preferred method for new users due to ease of use and additional security).
Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage. Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".
Securing your bitcoins
With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
If you prefer to "Be your own bank" and have direct control over your coins without having to use a trusted third party, then you will need to create your own wallet and keep it secure. If you want easy and secure storage without having to learn computer security best practices, then a hardware wallet such as the Trezor, Ledger or ColdCard is recommended. Alternatively there are many software wallet options to choose from here depending on your use case.
If you prefer to let third party "Bitcoin banks" manage your coins, try Gemini but be aware you may not be in control of your private keys in which case you would have to ask permission to access your funds and be exposed to third party risk.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email! 2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".
Where can I spend bitcoins?
Check out spendabit or bitcoin directory for millions of merchant options. Also you can spend bitcoin anywhere visa is accepted with bitcoin debit cards such as the CashApp card. Some other useful site are listed below.
Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The crew at /BitcoinMining would be happy to help you out. If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. If you would prefer to keep it simple there are several good options. You can view the global node distribution here.
Just like any other form of money, you can also earn bitcoins by being paid to do a job.
You can also earn bitcoins by participating as a market maker on JoinMarket by allowing users to perform CoinJoin transactions with your bitcoins for a small fee (requires you to already have some bitcoins.
The following is a short list of ongoing projects that might be worth taking a look at if you are interested in current development in the bitcoin space.
One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
one bitcoin is equal to 100 million satoshis
1,000 per bitcoin
used as default unit in recent Electrum wallet releases
1,000,000 per bitcoin
colloquial "slang" term for microbitcoin (μBTC)
100,000,000 per bitcoin
smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $10000 for one Bitcoin, a $10 meal would equal:

Hi fellas, this is my first ever post on privacy. I recently wrote about the existence of an open source DLT-based decentralized marketplace with a mission to enable free and private trade of goods and services. The marketplace description was posted on another subreddit but I think it's worth posting the description here too. Tbh I cant think of anything that qualifies more as "The intersection of technology, privacy, and freedom in a digital world" I hope my own description of the marketplace and its technology bellow will fuel your interest to read more about it. My even bigger hope is that some of you will decide to become first-hand beta testers as soon as the upcoming v3.0 of the marketplace hits the testnet (eta: a few weeks). You can also use the existing version (currently 2.3.5) of the marketplace to buy or sell products on the publicly accessible single community market there (or just play with it). The marketplace: It is called the Particl Marketplace and its ground breaking V3.0 is set to be released after 3 years of hard development work. The V3.0 will be the first version aimed at a wider public (normies and not only tech geeks). It will allow anyone to create easily decentralized personal storefronts or community markets or simply buy/sell goods on existing markets. The user-created markets/storefronts on the marketplace can be public if the access key is publicly announced on the Particl network or absolutely invisible to anyone that doesn’t know the access key (held by the creator). This is an intentional privacy feature and simply put, if you dont have the market access key (essentially a decryption key) there is absolutely no way to see/detect that some market exists. The marketplace is private by design and decentralized, with no middlemen or intermediaries whatsoever. The trades are protected by a two-way automated escrow via smart-contracts that de-incentivize and penalize dishonest behavior on both sides. In particular, the buy-flow forces the buyer to deposit 1x item value + payment and the seller 1x item value (+ sends item) into a common smart contract. If the buyer receives the product/service and its all good, then he unlocks the escrow so both can get their 1x item value deposits back and the seller receive his payment. The marketplace takes no sales commissions from the storefronts/markets and charges only a tiny listing fee (<0.01$) to prevent product listings spamming. All the marketplace generated fees go to the staking nodes that provide the hardware infrastructure for the p2p network to operate. The network nodes can be public or you can run them as Tor hidden services. The technology: The Particl Marketplace is crypto-agnostic and currently supports payments in BTC, PART, ZCoin (XMR, DAI, NIX, USDC, USDT are next in the pipeline and many more to come). It uses as a settlement layer its native coin PART and own blockchain, which is an up-to-date Bitcoin codebase with added privacy features like CT, RingCT (up to 32 mixins), Stealth addresses, etc. These privacy features are used in combination to keep the financial data, like escrows and transactions, private and most importantly un-linkable to the actual market buys/sells. For the users and markets related data exchange like posted listings, buy/sell flows, encrypted user communication, built-in cryptocurrency exchange, etc, the marketplace uses a DSN, currently its a custom Bitmessage variant called SMSG, which allows metadata stripped encrypted p2p data exchange (no sender, no receiver) Last but not least the marketplace desktop app (Particl Desktop) has a built-in option for using the Tor network via proxy. The important people: The cypherpunks behind Particl Marketplace have been OGs freedom advocates and pioneers in the privacy DLT field. For example, they were the first ever to implement features like RingCT, Bulletproofs, PoS, cold staking, etc on a Bitcoin codebase. Their privacy features implementations have been audited successfully by several respectable academics and security R&D providers, like QuarksLab. The team behind the project has been so far focused on building without any marketing/awareness efforts and thus have remained intentionally in the shadows. The latter is planned to change with the v3.0 release. One of the steps towards that will be the initiation of several long-planned awareness campaigns, like the Vendor Onboarding and Outreach Program, the Particl Academy (an easy to understand and learn about the technology portal) and many more. Me: I am a passionate freedom and privacy advocate that discovered the project 1.5 year ago and since then has become a member of their small but like-minded community ([email protected]/discord). My personal belief is that the Particl Marketplace provides a game-changing/breaking usecase to the world. At the minimum, due to the open source nature of the project, it will be a proof of concept that is bound to shift the global eCommerce paradigm.
About Ethereum mining pitfalls, risks, and threats
Bitcoin miners are massively switching to Ethereum. According to 8btc estimates, the payback period for a Bitcoin miner is 600 days, while for the same metric on Ether it only takes 200 days. But this goodness won’t last forever. Read about what threatens the development of Ethereum below. Hardware and Filling – Halfway to Success Experienced folks advise taking the most productive video cards, for example, the latest models from Nvidia and AMD. When choosing, pay attention to the amount of video memory (ideally from 2 GB), memory speed (with DDR 5 memory), bus width (better with a 256-bit bus), and cooling (basically there’s no competition to Radeon devices). Take Radeon RX 570, this 169 USD card produces 24-30 Mh/s, which is superb. The Illusion of Stability The entire multi-million community of Ether lovers trembled in early August when the Ethereum Classic network was subjected to several 51% attacks at once. In addition, in the first half of 2020 alone, over 5 attacks were carried out on popular DeFi platforms, including Balancer ($500,000 stolen) and bZx (17,500 ETH were stolen in total). Moreover, cybercriminals do not always use technical vulnerabilities, sometimes good old social engineering works. Reduction of Reward Ethereum developers have proposed to reduce the block mining reward by 75%. ConsenSys Managing Director John Leelik published the EIP-2878 proposal aimed at reducing inflation and preserving purchasing power. If supported, the reward will drop to 0.5 ETH. The transition of ETH to ETH 2.0 (PoS) We already wrote about this in the article "Problems of Ethereum Mining", and you can also watch the interview by Peter McCormack with the project founder Vitalik Buterin. While the opportunity is still there, we offer everyone to get the most out of it and mine profitably. For example, take a closer look at the new CoinFLy ETH Pool, that nowadays offers more rewards than others, at least by 10%. Profit That is Not Profit A hidden and obvious problem is choosing the pool based on its profitability. If you only have a few capacities, then it is better to choose a pool that uses the PPS+ model, if you’ve got a lot of them, then a powerful pool with PPLNS is better. And if you’ve got so many capacities that there’s even enough for others, then you can also go SOLO, buddy. More details - here.
Disclaimer: This is sort of my own arbitrary editing, so there could be some misunderstandings. I root for the spread of good spirits and transparency of IF. 📷 Hans Moog [IF]어제 오후 2:45 So why don't we just copy Avalanche? Well that's pretty simple ... 📷 Hans Moog [IF]어제 오후 2:47 1. It doesn't scale very well with the amount of nodes in the network that have no say in the consensus process but are merely consensus consuming nodes(i.e. sensors, edge devices and so on). If you assume that the network will never have more than a few thousand nodes then thats fine butif you want to build a DLT that can cope with millions of devices then it wont work because of the message complexity. 2. If somebody starts spamming conflicts, then the whole network will stop to confirm any transactions and will grind to a halt until the conflict spamming stops.Avalanche thinks that this is not a huge problem because an attacker would have to spend fees for spamming conflicts which means that he couldn't do this forever and would at some point run out of funds. IOTA tries to build a feeless protocol and a consensus that stops to function if somebody spams conflicts is really not an option for us. 3. If a medium sized validator goes offline due to whatever reason, then the whole network will again stop to confirm any transactionsbecause whenever a query for a nodes opinion can not be answered they reset the counter for consecutive successful voting rounds which will prevent confirmations. Since nodes need to open some ports to be available for queries it is super easy to DDOS validators and again bring the network confirmations to 0. 📷 Hans Moog [IF]어제 오후 3:05 4. Avalanche still processes transactions in "chunks/blocks"by only applying them after they have gone through some consensus process (gathered enough successfull voting rounds),which means that the nodes will waste a significant amount of time where they "wait" for the next chunk to be finished before the transactions are applied to the ledger state. IOTA tries to streamline this process by decoupling consensus and the booking of transactions by using the "parallel reality based ledger state" which means that nodes in IOTA will never waste any time "waiting" for decisions to be made. This will give us much higher throughput numbers. 📷 Hans Moog [IF]어제 오후 3:11 5. Avalanche has some really severe game theoretic problems where nodes are incentivized to attach their transactions to the already decided parts of the DAG because then things like conflict spam won't affect these transactions as badly as the transactions issued by honest nodes.If however every node would follow this "better and selfish" tip selection mechanism then the network will stop to work at all. Overall the "being able to stop consensus" might not be too bad since you can't really do anything really bad (i.e. double spend) which is why we might not see these kind of attacks in the immediate future but just wait until a few DeFi apps are running on their platform where smart contracts are actually relying on more or less real time execution of the contracts. Then there might be some actual financial gains to be made if the contract halts and we might see alot of these things appear (including selfish tip selection). Avalanche is barely a top 100 project and nobody attacks these kind of low value networks unless there is something to be gained from such an attack. Saying that the fact that its live on mainnet and hasn't been attacked in 3 weeks is a proof for its security is completely wrong. Especially considering that 95% of all stake are controlled by avalanche itself If you control > 50% of the voting power then you essentially control the whole network and attacks can mostly be ignored I guess there is a reason for avalanche only selling 10% of the token supply to the public because then some of the named problems are less likely to appear 📷 Navin Ramachandran [IF]어제 오후 3:21 I have to say that wtf's suggestion is pretty condescending to all our researchers. It seems heavy on the troll aspect to suggest that we should ditch all our work because iota is only good at industrial adoption. Does wtf actually expect a response to this? Or is this grand standing? 📷 Hans Moog [IF]어제 오후 3:22 The whole argument of "why don't you just use X instead of trying to build a better version" is also a completely idiotic argument. Why did ETH write their own protocol if Bitcoin was already around? Well because they saw problems in Bitcoins approach and tried to improve it. 📷 Hans Moog [IF]어제 오후 3:27 u/NavinRamachandran [IF] Its like most of his arguments ... remember when he said we should implement colored coins in 2nd layer smart contracts instead of the base layer because they would be more expressive (i.e. turing complete) completely discarding that 2nd layer smart contracts only really work if you have a consensus on data and therefore state for which you need the "traceability" of funds to create these kind of mini blockchains in the tangle? Colored coins "enable" smart contracts and it wouldnt work the other way round - unless you have a platform that works exactly like ETH where all the nodes validate a single shared execution platform of the smart contracts which is not really scalable and is exactly what we are trying to solve with our approach. 📷 Navin Ramachandran [IF]어제 오후 3:28 Always easier to criticise than build something yourself. But yet he keeps posting these inflammatory posts. At this point is there any doubt if he is making these comments constructively? 📷 Hans Moog [IF]어제 오후 3:43 If he at least would try to understand IOTAs vision ... then maybe he wouldn't have to ask things like "Why don't you just copy a tech that only works with fees" 📷 Hans Moog [IF]어제 오후 4:35 u/Shaar
I thought this would only be used to 'override' finality, eg if there were network splits. But not in normal consensus
That is not correct. Every single transaction gets booked on arrival using the parallel reality based ledger state. If there are conflicts then we create a "branch" (container in the ledger state) that represents the perception that this particular double spend would be accepted by consensus. After consensus is reached, the container is simply marked as "accepted" and all transactions that are associated with this branch are immediately confirmed as well. This allows us to make the node use all of its computing ressources 24/7 without having to wait for any kind of decision to be made and allows us to scale the throughput to its physical limits. That's the whole idea of the "parallel reality based ledger state" instead of designing a data structure that models the ledger state "after consensus" like everybody else is doing it is tailored to model the ledger state "before consensus" and then you just flip a flag to persist your decision. The "resync mechanism" also uses the branches to measure the amount of approval a certain perception of the ledger state receives. So if my own opinion is not in line with what the rest of the network has accepted (i.e. because I was eclipsed or because there was a network split), then I can use the weight of these branches to detect this "being out of sync" and can do another larger query to re-evaluate my decision.(수정됨)
Also what happens in IOTA if DRNG notes would fall out, does the network continue if no new RNGs appear for a while? Or will new nodes be added sufficiently fast to the DRNG committee that no one notices?
Its a comittee and not just a single DRNG provider. If a few nodes fail then it will still produce random numbers. And even if the whole comittee fails there are fallback RNG's that would be used instead 📷 Hans Moog [IF]어제 오후 4:58 And multiverse doesn't use FPC but only the weight of these branches in the same way as blockchain uses the longest chain wins consensus to choose between conflicts. So nodes simply attach their transactions to the transactions that they have seen first and if there are conflicts then you simply monitor which version received more approval and adjust your opinion accordingly. 📷 Hans Moog [IF]어제 오후 5:07 We started integrating some of the non-controversial concepts (like the approval reset switch) into FPC and are currently refactoring goshimmer to support this We are also planning to make the big mana holders publish their opinion in the tangle as a public statement, which allows us to measure the rate of approval in a similar way as multiverse would do it So its starting to converge a bit but we are still using FPC as a metastability breaking mechanism Once the changes are implemented it should be pretty easy to simulate and test both approaches in parallel 📷 Serguei Popov [IF]어제 오후 5:53
So the ask is that we ditch all our work and fork Avalanche because it has not been attacked in the month or so it has been up?
u/NavinRamachandran [IF] yeah, that's hilarious. Avalanche consensus (at least their WP version) is clearly scientifically unsound. 📷 Hans Moog [IF]어제 오후 9:43 u/wtfmaybe you should research avalanche before proposing such a stupid idea and you will see that what I wrote is actually true 📷 Hans Moog [IF]어제 오후 9:44 paying fees is what "protects" them atm and simply the fact that nobody uses the network for anything of value yet we cant rely on fees making attack vectors "inattractive" 📷 Serguei Popov [IF]어제 오후 10:17
well (1.) very obviously the metastability problems are not a problem in practice,
putting "very obviously" before questionable statements very obviously shows that you are seeking a constructive dialogue📷(to make metastability work, the adversary needs to more-or-less know the current opinion vectors of most of the honest participants; I don't see why a sufficiently well-connected adversary cannot query enough honest nodes frequently enough to achieve that)
(2.) .... you'd need an unpredictable number every few tens/hundreds milliseconds, but your DRNG can only produce one every O(seconds).
the above assumption (about "every few tens/hundreds milliseconds") is wrong
We've had this discussion before, where you argued that the assumptions in the FPC-BI paper (incl. "all nodes must be known") are not to be taken 100% strictly, and that the results are to be seen more of an indication of overall performance.
Aham, I see. So, unfortunately, all that time that I invested into explaining that stuff during our last conversation was for nothing. Again, very briefly. The contents of the FPC-BI paper is not "an indication of overall performance". It rather shows (to someone who actually read and understood the paper) why the approach is sound and robust, as it makes one understand what is the mechanism that causes the consensus phenomenon occur.
Yet you don't allow for that same argument to be valid for the "metastability" problem in avalanche,
Incorrect. It's not "that same argument". FPC-BI is a decent academic paper that has precisely formulated results and proofs. The Ava WP (the probabilistic part of it), on the other hand, doesnotcontain proofs of what they call results. More importantly, they don't even show a clear path to those proofs. That's why their system is scientifically unsound.
even when there's a live network that shows that it doesn't matter.
No, it doesn't show that it doesn't matter. It only shows that it works when not properly attacked. Their WP doesn't contain any insight on why those attacks would be difficult/impossible. 📷 Hans Moog [IF]어제 오후 10:56 That proposal was so stupid - Avalanche does several things completely different and we are putting quite a bit og effort into our solution to pretty much fix all of Avalanches shortcomings If we just wanted to have a working product and dont care about security or performance then we could have just forked a blockchaib I am pretty confident that once we are done - its going to be extremely close to the besttheoretical thresholds that DLTs will ever be able to achieve for an unsharded baselayer ------------------------------------------------------------------------------------------------------------- 📷 Bas어제 오전 2:43 Yesterday I was asked how a reasonably big company no one has heard of could best move forward implementing Access for thousands of locations worldwide. (Sorry for the vagueness, it’s all confidential.) They read the article and want to implement it because it seems to fit a problem they’re currently trying to solve. Such moves will vastly increase the utility of protocols like IOTA, and is what the speculation is built on. I do not think you can overestimate what impact Access is going to have. It’s cutting out the middleman for simple things; no server or service needed. That’s huge. So yes, I think this space will continue to growu/Coinnave -------------------------------------------------------------------------------------------------------------- 📷 Angelo Capossele [IF]2020.10.02. In short: we are planning a new v0.3.0 release that should happen very soon. This version will bring fundamental changes to the structure of the entire codebase (but without additional features) so that progressing with the development will be easier and more consistent. We have also obtained outstanding results with the dRNG committee managed by the GoShimmer X-Team, so that will also be integral part of v0.3.0. After that, we will merge the Value Tangle with the Message Tangle, so to have only one Tangle and make the TSA and the orphanage easier to manage. And we are also progressing really well with Mana, that will be the focus after the merge. More or less this is what is going to happen this month. We will release further details with the upcoming Research Status Update📷
The world’s first cryptocurrency, Bitcoin is stored and exchanged securely on the internet through a digital ledger known as a blockchain. Bitcoins are divisible into smaller units known as satoshis — each satoshi is worth 0.00000001 bitcoin. Two-thirds of people who use Coinbase are willing to leave the platform following reports that the U.S. exchange plans to sell user data to two government agencies for $250,000. Bitcoin is a new currency that was created in 2009 by an unknown person using the alias Satoshi Nakamoto. Transactions are made with no middle men – meaning, no banks!
