1  Local / Meetings (Nederlands) / Re: Monero Meetup Utrecht on: May 06, 2019, 03:17:19 PM
Zie ik je op donderdagavond 9 mei weer in Bar De Stadstuin? Europalaan 20 in Utrecht, van 19 tot 21 uur.

De 3e Monero Meetup Utrecht gaat over de geschiedenis van Monero, de vertrouwelijke cryptovaluta die in april vijf jaar bestond. Ik vertel het verhaal van Monero aan de hand van 10 sleutelmomenten. 5 momenten was het plan, maar er is te veel gebeurd. Het begon met een mysterieus genie dat samenwerkte met een stel oplichters, gevolgd door een opstand tegen de oprichter. En daarna liep het uit de hand.

Vergeet niet om je aan te melden voor deze meetup, of de volgende van 11 juli: https://www.meetup.com/monero-meetup-utrecht-nl/

If you're in the Netherlands, join us for the first Monero Meetup in Utrecht on Thursday night, from 7 PM to 9 PM in Bar De Stadstuin, Europalaan 20.

Nieuws voor de liefhebbers van privacy, crypto, bier en bitterballen: op donderdagavond 10 januari organiseer ik de eerste Monero Meetup Utrecht in Bar De Stadstuin, Europalaan 20, van 19.00 tot 21.00 uur.

Om te beginnen kijken we eens naar Monero-apps voor op je telefoon: Wat kun je ermee doen? Welke apps zijn betrouwbaar? En we kunnen ze meteen uitproberen. Neem iets leuks mee dat je voor een symbolisch bedrag wilt verkopen. Meetup.com vond het thema Monero Market te commercieel en heeft mijn meetup-groep verwijderd. Maar we laten ons natuurlijk niet door een gecentraliseerd netwerk censureren.

Poster:

Ik houd een kort praatje over de geschiedenis van mobiel betalen met XMR, en hoe het dankzij Bulletproofs mogelijk is om voor de lol betalingen te doen met lage transactiekosten. En ik wil zelf graag eens bij iPhone-gebruikers kijken hoe de iOS-apps werken. Maar het gaat vooral om gezelligheid.

Tips voor eten vooraf. Je kunt voor en achter het gebouw De Stadstuin gratis parkeren. Met het openbaar vervoer is de bushalte Anne Frankplein of Balijebrug dichtbij. Meer informatie op Reddit.

Volgende meetups zijn ook op donderdagavond gepland, eens in de twee maanden: 14 maart, 9 mei en dan een zomerpauze. Het thema voor 14 maart is ASIC resistance.

4  Alternate cryptocurrencies / Speculation (Altcoins) / Re: [XMR] Monero Speculation on: December 17, 2017, 01:42:39 AM
Hey, has anybody used the mobile wallet "monerujo" (https://play.google.com/store/apps/details?id=com.m2049r.xmrwallet)? I'm due to move most of my XMR off the exchanges and I'm not in a position to host a full node, nor do I have enough that I would bother with cold storage.

Monerujo is open source and as reliable as it gets. It's just a wrapper for the regular Linux wallet anyway. The Monero subreddit recommends Monerujo and warns that Freewallet is a scam.

For long-term storage, you could create a written paper wallet using an offline address generator, so you don't need to connect to the blockchain at all. Of course you can't check your funds on a block explorer - that's a downside of Monero's anonymity in this case.

outside this forum, twitter is the centre of the crypto universe

all FST fans follow the main Fastcoin twitter account, like all the tweets, and retweet and tweet your own FASTCOIN tweets
https://twitter.com/fast_coin


Done. Shouldn't we also revive the subreddit? It looks so dead, I'm afraid to touch it... Smiley

sweet new website!
https://www.fastcoin.ca/

Great design! Could you change the Dutch text to "Bloktijd: 12 seconden"? In "12 tweede bloktijd", tweede means second as in #2.

Please don't use Google Translate for anything you publish. I'm a professional translator and I can tolerate amateur translations in open-source software, but machine translation will be gibberish.

This coin is still the fastest and has the longest blockchain. Neither of those things are very useful for the purposes of being a currency, but they are novelties and they are definitely one of a kind. My thoughts are that one of a kind novelties are enough to maintain value, especially if you believe in blockchain tech.

We understand that our coin may not be "Perfect" but like Bitcoin and all the rest of them, for the purpose of storing and exchanging value, FST it is "Good Enough" to perform the task.  

Looking forward to getting past the teething stages of our coin, and moving on to much larger specific use cases.

/C

Yes, this was a significant quote. Besides the speed and the name, Fastcoin is fascinating as an experiment in 'naive scaling'. If Fastcoin can mine 50 times as many blocks as Bitcoin, imagine how large Bitcoin blocks could be... Of course, there are limits. It took me two weeks to download the blockchain from scratch on a new hard drive. We really need an SPV wallet, or a web wallet that saves the keys locally. In other words, a reliable method to use FST without downloading the entire blockchain (and I don't mean downloading a zip file).

Someone said there's a mobile wallet. How does that work?

The price has gone up 5x since I bought more FST in addition to my original holdings from years ago. But there's a long way to go, I want it to go up 100x. Let's look at the long term: it should be user-friendly before we start bothering major exchanges again.

Name suggestion: Snarks.

But there are more than 3 things wrong with Zcash:

4. Transparent transactions are allowed, enabled by default and even possible if the receiver wants to remain private.

5. The creation of a transaction is slow and resource-heavy.

With regard to point 5, CredaCash claims to use a much more efficient hash, but that's hardly a real blockchain. It uses 'permissioned witnesses' instead of miners and will premine everything. Source: http://credacash.com/compare/

When the Voxelus VR Marketplace launches officially (April 19th), it will be the #1 VR content provider in the world. The only way to buy/sell anything there, is with Voxels.
 
#gamechanger

Why would users choose a deliberately crippled platform where you could use only one kind of currency, controlled by a company?

Hm, an in-game currency represented by Michael Terpin. It'll be just as successful as Munne!
11  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] [MNE] Munne丨POS 丨POD丨New Wallet丨Marketing丨Alpha - Browser Game丨University on: January 29, 2015, 12:50:50 PM
btw, i don't expect an increase of value for munne with this alpha release imho, but maybe if Terpin work his magic it will.  To me, the real game changer will be when there is a crypto-implementation of munne into the University and in the game, so a real usuability for this coin.

I agree. Patience is needed if you want Munne to do anything worthwhile.

Looks strange no buyer and no vendors

I don't understand why some people are complaining about low trading volume instead of using this opportunity.
Trading is fun when there's a large spread between bids and asks and the price goes up and down!  Cool

No, don't pull your sells - add some buy and sell orders on Bittrex, so we can keep the trading volume above the minimum. There's a big spread between bids and asks, which makes it easy to make money by trading on both sides.
13  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] [MNE] Munne丨POS 丨POD丨New Wallet丨Marketing丨Alpha - Browser Game丨University on: December 05, 2014, 02:21:55 PM
Great to see the 7 stars, and the price is rebounding from 1600 to 2500 Smiley

Minor feature request for the wallet: in the transaction view, could we have a drop down option to display both sent and received funds, but no mining? If you select 'All', the staking transactions are crowding out everything else.
14  Bitcoin / Bitcoin Discussion / Re: Could something like Venmo make use of bitcoin? on: December 02, 2014, 08:51:32 PM
You can deposit ven at Kraken.com and trade XBT/XVN (Bitcoin vs. Ven) there. I'm not sure if this is available in all us states, but if you have an address in Montana, New Mexico or South Carolina (the "no money transmitter license" required states) it should work, I think.

Venmo is an app for paying in dollars, it's not related to the Ven currency Smiley

Quote
In a brainstorming session, they came up with the “ven” from vendere, the Latin word for to sell, and “mo” from mobile.
http://www.businessweek.com/articles/2014-11-20/mobile-payment-startup-venmo-is-killing-cash

It's more like Apple Pay or TransferWise. I guess they have low costs because they process a high volume of transactions just like banks, without having to build the payment network like banks do. Using bitcoin could make these services cheaper, but it's not the low-hanging fruit. In the short term, they'll be competing with digital currency, and they're more efficient than banks, credit card companies or Western Union.

In related news, major Dutch banks recently announced they were looking in to how blockchain technology could make settlements between banks more efficient. Video in Dutch: www.rtlnieuws.nl/economie/home/gaat-bitcoin-techniek-banken-helpen

As you can see the altcoin market is bleeding, almost every coin in red. Now is the time to buy Smiley


Exactly! The only green one in the first two columns isn't actually an altcoin, but a bitcoin mining share.

The link above is ("Andreas Antonopoulos on the Future Of Bitcoin" And alt-Coins.) From the Toronto Bitcoin Expo on October 30th.

If you have time the whole thing is really interesting. If not watch the last 8-10 Minutes of it.

I haven't watched the whole video yet, but I read the same type of ideas in a classic post called
How we crypto-geeks get it wrong & the reality of altcoin success.

Quote
IN SUMMARY: We crypto geeks have to get reality! To succeed longterm, a coin must address these issues:

1. Users only care about ease of use & security, they really don't care about our x1186SHAPOWPOS, inverted 3x algo
2. Recognize the two disparate economies of cryptocurrencies (Miners vs Users)
3. Solve how a coin gets into the real users wallets, not the miners/traders
4. Give the users something do with the coin

One of the things I like about Munne is that the founders realized they needed to reach a wider audience than just miners and traders. Actually, I hope they won't pay too much attention to Bitcointalk once the Munne Forum is up and running. This used to be the best place to discuss the pros and cons of altcoins, but all the scams have made people paranoid.

And of course the game is a nice way to give users 'something to do with the coin'.

Other things to do for nervous Nellies:

- Promote Munne on social media and other forums.
- Use it to buy things through CoinPayments (I don't see Munne on CoinGateway yet).
- Ask a friend to download the wallet if you want to pay for a dinner, buy someone a present together or something like that.
- Try to sell stuff or services for Munne.

So I hope someone will help develop this coin, with regard to security patches and so on.

A block explorer would be nice, too...
18  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][GAY] Gaycoin on: November 03, 2014, 02:27:54 PM
No, no sir, it's not dead. It's resting.
I'm mining gaycoin like they're going out of style!
Not getting any transaction fees, though.



Today, I have more hashes than the network. How is that even possible? Are my own hashes excluded from the network count?



So if you wanted to practice a 51% attack, you could easily rape this coin. But that seems pointless. And it would make you a homosexual, of course.  Wink

I like the GAY, in the same way that one can be attached to a crippled pet, or to stay on topic, an mentally unstable ex-Christian twink with daddy issues. It's so pretty, and so easy... the only coin I ever managed to solo mine in significant numbers.

The last thing I heard from the coin starter was "We are looking for devs to fix the bug not syncing wallet". I guess the wallet simply wasn't syncing for many users because there was no one else on the network. This coin was obviously made by a graphical designer whose coding skills might be less than fabulous. So I hope someone will help develop this coin, with regard to security patches and so on.

GAY is still listed on a few exchanges, even though the coin starter said on the facebook page that he wanted to delist it and only sell it through his website:

https://comkort.com/market/trade/gay_doge
https://www.palth.net/market/GAY/BTC

At least, I think that's the scrypt gaycoin and not the SHA-256 gaycoin with the hideous rainbow logo, since it was announced to be on those exchanges.

BTW, I used the addnodes from the website:

Ironically, my Ripple and Stellar withdrawals are the first to be completed.

For the record: According to Ripple Labs, the tfPartialPayment hack was due to incorrect implementation by Justcoin, as well as a general lack of precautions.
