1  Local / Português (Portuguese) / Minha visão sobre segwit on: September 28, 2019, 02:54:29 PM
Fiquem muito atentos em utilizar endereços segwit para cold storage e em geral armazenamento de longo prazo.

Para quem nao sabe:

Endereço legacy: 1fjpBVdJuf9j7BFjPyaxmoWzMNWJ8tNiv

Endereço multisig ou segwit: 3FviNfPhyzLctKVm5cgEJg554Kc4vrKQE4

Endereço segwit: bc1qzmye682utukmerdhvc63cwgnmjh4fjpuv8cpz6


Basicamente com endereço segwit a transação nao tem mais a parte da assinatura incluida no bloco principal, ela è colocada num espaço a mais que so os nodes atualizados com o soft fork podem ver (este espaço seria o segregated witness, em portugues o "testemunho segregado").

Desse jeito as transaçoes ocupam menos espaço, porem a segurança das mesmas è so garantida pelos miners, sendo que a parte da assinatura nao è mais disponibilizada como numa transação legacy. Os nodes com segwit habilitado podem ver a assinatura, porem estamos falando de um softfork, ou seja, caso os miners decidissem de nao querer mais segwit, muitos unspent outputs se tornariam spendable, ou melhor, se tornariam anyonecanspend. Para aprofundar o argumento, tem essa materia: https://nchain.com/en/blog/risks-of-segregated-witness-mining-cartels/ (o cara que escreveu ela, CSW, è um estelionatario bem conhecido no ambiente BTC, porem o conteudo è escrito de forma correta, nao tem politicagem)

Segwit è uma extensão totalmente opcional e facultativa, entroduzida com um softfork que nao è absolutamente obrigatorio, e na pior das situaçoes (chain reorg ou outro tipo de esquema feito pelos miners), pode ser revertido.


RESUMINDO:

Antes do segwit:

As transações eram protegidas pelo hashrate e pela assinatura


Depois do segwit (utilizando endereços segwit):

As transações sao somente protegidas pelo hashrate


Eu aconselho de utilizar sempre endereços legacy para nao arriscar nemhum fundo, e minha dica è maxima cautela com qualquer tipo de novidade entroduzida por hard fork.



Adicional: https://p2sh.info/dashboard/db/bech32-statistics?orgId=1

Este grafico mostra em tempo real a quantia de BTC armazenada em endereços bech32 compativeis com segwit

Atualmente aproximadamente 360k BTC estao atras de bech32, ou o 2% dos BTC circulantes. Quanto mais esse incentivo crescer, mais pode subir o incentivo ao roubo.

I'd like to start trading, but what happens when you get profit from a new coin? you pay taxes as individual (like capital gain) or you must open a registered company?
7  Alternate cryptocurrencies / Altcoin Discussion / NEM/XEM gaining ground in Japan on: July 12, 2017, 04:54:25 PM
Japan, a front-runner in blockchain adoption, has recently announce to start testing applications of blockchain technology in several governmental functions. The Japanese government has expressed interest to use the blockchain for, among other things, land-registration and tender offers. Links can be found here: https://btcmanager.com/japans-government-to-test-blockchain-system-q1-2018/ and here: https://www.cryptocoinsnews.com/japan-place-entire-property-registry-blockchain/.

In addition to these developments Infoteria, a Japanese company, has announced that is has succesfully used NEM/Mijin for a trial where shareholder voting was done on the blockchain. A link to the original announcement can be found here https://www.infoteria.com/jp/news/press/2017/06/01_01.php (You'll need google translate here). Combined with the news that one of the largest Japanese exchanges Coincheck has acquired 300 million XEM (around 50 million USD at the time) as a reserve currency. Source https://www.reddit.com/r/nem/comments/6kr7o2/japan_exchange_coincheck_purchased_300_million_xem/.

These facts combined could signal very strong support from both Japanese government and Japanese corporations for the NEM/XEM blockchain. This could very well be the start of a string of NEM related announcements coming from Japan.

So what does everyone think about PTOY (Patientory). ANN: https://bitcointalk.org/index.php?topic=1886446.0
They aim to leverage blockchain technology to solve old problems in the healthcare industry. The company is located in the US and is already talking with leading healthcare centers there.

It was also just added to bittrex which triggered a bit of a volatile situation.
9  Alternate cryptocurrencies / Speculation (Altcoins) / HMQ the next unicorn? on: June 08, 2017, 12:37:12 PM
Humaniq, a start-up that aims to bring banking to the next level by allowing the use of biometric data to provide identification on your smartphone and allowing you to benefit from a wide range of banking solutions.

Humaniq has been named the 7th best new fintech start-up by cointrelegraph. https://cointelegraph.com/news/top-seven-fintech-startups-to-follow

The team has also just announced a new office in Silicon Valley which will help them accelerate their global impact due to proximity to leading organization in San Francisco. http://www.econotimes.com/Blockchain-company-Humaniq-opens-office-space-in-San-Francisco-744983.

In addition the CEO of the company is scheduled to hold an AMA live on facebook to address any questions supporters and investors might have. They've also promised a few big announcements during this AMA.
https://www.facebook.com/events/758594294319554/?active_tab=discussion.

All of this combined possibly accommodate the rise of a new star in the Fintech world.
10  Alternate cryptocurrencies / Altcoin Discussion / Humaniq CEO holds AMA on thursday on: June 06, 2017, 12:34:11 PM
Humaniq's CEO Dinis Guarda is holding a live AMA on facebook thursday 17:00 UTC. During the session he'll also be announcing some big developments in humaniq's roadmap. You can check the event page for yourself here https://www.facebook.com/events/758594294319554/?active_tab=discussion.

Humaniq is developing banking solutions for those people who are currently unable to obtain these services due to the lack of identification in a lot of the poorer countries. Humaniq aims to solve this issue by leveraging Biometric ID and Blockchain solutions. It's announcement post is located here https://bitcointalk.org/index.php?topic=1711764.0

I believe HMQ has a good potential to rally before and after this AMA. It is currently traded on Bittrex. I'd say it's worth it to check out.

13  Alternate cryptocurrencies / Altcoin Discussion / DONT TRUST CRYPTSY on: February 05, 2014, 09:16:15 AM
Oh my god,

Went to sleep really happy last night about the price etc only to wake up to see someone hacked my Cryptsy and stole all my 350 vtc i've been working really hard on for the past 2 weeks.. My e-mail has also been hacked apparently..

My only guess woud be it's an inside job because i've used different passwords for everything i did. They just delayed the deposits only to sell your funds and cash out the btc right when they enter your account.

1DCkj4Ub1m323NStdP2Udzq3918bA8MDxp   2.44192461

This was the BTC adress used in the hack..

I'm really feeling like shooting myself right now. Been trying to help the vtc community so hard for the past week only to get treated like this by a worthless hacker.

Well guess it's void to ask for any support/help or whatever but if you feel like i've helped you out in the past days. I would really appreciate it...

LVn6rPFuEtAtcpaEKLRdGKYopDtE6cNvQBb

So my advice would be STAY AWAY from cryptsy, these kind of exchanges have fucked over so many people in the last few weeks/months it's unbelievable.
14  Alternate cryptocurrencies / Announcements (Altcoins) / VTC - Promotion & Marketing fund on: February 04, 2014, 09:34:37 PM
Hey fellow verters!

Ofcourse we're all very happy about the current rise of Vertcoin. We've been the fastest rising coin for 3 days in a row now with the 24h increase reaching as high as 357% earlier  today!
And since you're all reading this i'm convinced you know everything about the awesome features Vertcoin has to offer when you compare them to LTC for example.

But after reaching this much volume the rise probably hold for a while in a few days. And this is we're we (the community) should come in. We've got to start organising things to make people able to use VTC for practical purposes other than speculating on the value of the coin. We need to start Recruiting people with extensive technical knowledge to create trade platforms, we need people with a marketing background to keep promoting this coin by actively writing well-constructed articles about it's benefits in comparison to other coins. What we also need is people with graphical skills, creating infographics, banners, t-shirts and what not. And ofcourse we need to get more miners to get the network even more stable.

To get all these things done we'll need well-educated people willing to dedicate alot of their time to this coin. To attract these kind of people i suggest we start a marketing & promotion fund to make sure we can compensate these people for their time and dedication to our project.

Now to start i've got a few ideas wich i think can help this coin to get on it's way to replacing LTC or what the heck, even BTC.

Websites

Currently there isn't really a way to actually spend and use your vertcoins. A platform should be developed to do all kinds of things with your coins, exchange for BTC/LTC and even directly to fiat, quick escrow services, a pay-pall specificly designed for vertcoin and some sort of e-bay where people can offer goods to be exchanged for VTC and VTC only.

You could also think about lottery/casino websites for vertcoin where you could play games like poker/blackjack with your VTC.

Social Media

We should also start a Social-Media campaign promoting the pro's of vertcoin compared to the other cryptocurrencies. Social media will be especially important in the campaign to reach the mainstream public. ( At wich point known retailers will also start accepting VTC)

Articles/essays

We also need professional writers and perhaps journalists to promote the coin, they will be writing contructive posts about what whould be the benefits of using VTC as a currency. This campaign will be aimed at the well-educated people and ofcourse at possible investors.

Ofcourse there are many more things we could do to promote the coin but i believe that if we put time/effort in these causes vertcoin will surpass any other Cryptocurrency and become the next standard.
Let's get involved people and create REAL demand for our precious coin.  

I'd like to start the fund to make these great things happen right now to start these projects as fast as possible, for more information about myself check this topic.

I know the price is fluctuating alot atm. But think a moment for yourself, would you rather own 100 VTC with a value of 5 dollar or would you rather own 90 VTC with a value of 10x or even 25x that amount due to awesome community effort?

Start sharing and let's get this project going. Donations can be forwarded to this adress: Vn6rPFuEtAtcpaEKLRdGKYopDtE6cNvQBb  
I'll keep daily or even sub-daily updated about the amount of VTC in the wallet and the community will have influence about where we are going to spend it and how much by voting.

Let's get VTC to keep going Vertical!

For more information you can aways send me a PM or ask for my E-mail through a PM

Cheers and keep up the good work!

15  Alternate cryptocurrencies / Mining (Altcoins) / Quick question on: February 03, 2014, 10:37:25 AM
Hey, i've got a laptop now on wich i'd like to manage my wallets.
How can i transfer my wallets to this laptop?
And is there a way to control my rig with my laptop?(Rig is in an office atm. while the laptop is at home)

Thnx!
16  Alternate cryptocurrencies / Altcoin Discussion / Marketing and Promotion on: February 02, 2014, 01:00:24 PM
Hey crytolovers!

I've been lurking around these forums for a few months now after i noticed btc surging to $200-300 on Mt.Gox.
After a while i decided to buy my own little mining rig, 2x MSI R9 280x 3gb and i've been mining happily ever since.

But i think it's now time to get more actively involved in the crypto community so i'd like to offer my services as a CMO for an innovative and promising coin here.

A little bit about myself,
I'm a 2nd years IBM(International Business and Management) student at a university in the Netherlands and i've been working in the sales and marketing industry since i've been 15 years old. Started off at a sales company called Hot Networkz (Some ppl from Holland may know the name) where i've worked for 2 years as a Project Manager.
A year ago i did something completely different, I wrote the website text from an internationally operating Analysis business, http://www.pathintelligence.com/ (The english website) and for it's dutch branch http://retailvisitor.com/.

For more information about myself and for any other questions/offers you can contact me on Fastpow@gmail.com.

Thank you for reading and have a nice day!

Michael
