1  Alternate cryptocurrencies / Altcoin Discussion / [Guide] DEx.top: How to buy and sell Ethereum and ERC-20 tokens in a decentraliz on: July 25, 2018, 12:15:33 PM
Traditional centralized exchanges play a big role in the crypto space, allowing users to buy and sell cryptocurrencies quickly and intuitively. However, with the convenience that a centralized service provides, a few disadvantages come along. Traditional exchanges have shown that they are prone to security failures like hacks and exit scams, an issue that has cost investors and traders millions of dollars and has deterred would-be crypto enthusiasts from joining the scene.

Luckily, there is an alternative that is becoming more popular every day. Decentralized crypto exchanges like DEx.top allow users to buy and sell Ethereum and ERC-20 tokens in a convenient manner while still giving them the ability to hold on to their funds in their own wallet. Today, we’re going to learn about the DEx.top exchange and how to use it so that you too can protect yourself from the woes of centralized exchanges.

3  Alternate cryptocurrencies / Altcoin Discussion / LevelNet, a Disrupting Cyber Security Platform on: March 29, 2018, 11:49:39 AM
As technology continues to evolve at an astonishing pace, changing the way we connect with each other and exchange information, so do the threats that have come with it. From hackers to deceptive ads to advanced malware, surfing the web can be a dangerous venture, and doing so unprotected may cost you your work or personal files and even your hard-earned savings.

As cybercriminals continue to perfect their craft and come up with new attack vectors, cybersecurity professionals, along with their software solutions, must evolve at an even faster pace and explore new and creative solutions. While legacy antivirus software has played a big role in keeping us safe from hackers and malware in the past, a time has come when new strategies must be applied.

This is where LevelNet, a next-gen cybersecurity platform, comes in!

To put it simply, LevelNet is the world’s first decentralized cyber security solution. It acts alongside traditional anti-virus software, functioning as a network of collective information security in which each user is constantly updated and protected against new threats. LevelNet leverages the information collected by each and every users in the network and the measures applied by their respective antiviruses in order to keep every member device safe.

While some anti-virus may be more advanced than others or apply better measures to certain attacks than others, with LevelNet each user can have access to the most advanced security measures for each particular threat without the need to search and pay for one or several advanced anti-virus software solutions, resulting in a much more secure experience for all those involved.

4  Alternate cryptocurrencies / Announcements (Altcoins) / [ANN] MOYA Networks - Bringing Data to Africa at the Speed of Light on: October 04, 2017, 07:09:46 AM
*I am posting this thread on behalf of Coremedia.info for Moya Networks*



WEBSITE  |   WHITEPAPER  |  TEAM
The low Data penetration rate in Southern Africa compared to levels elsewhere clearly indicates the pent-up demand for broadband connectivity. Moya Networks, a project created by seasoned Pan-African ICT professionals, experienced in developing and managing ICT companies, plans to bring transparency to the Southern African wholesale markets in an effort to ramp up internet connection inclusion in the area.
 
In the Southern African wholesale market, Cables such as SAT-3 and WACs until recently have held unchallenged market positions, which has resulted in data prices that are between 10 to 20 times more expensive than those in markets outside of Africa. Market research carried out on behalf of Moya currently estimates the cost of a single STM-1 for international connectivity to Africa to be US$115,000 per month. The current market price for satellite access to Africa is between US$4,000 and US$8,000 per Mbps per month.
 
In order to fix the current lack of efficiency found in this market, Moya will leverage its team’s experience and contracts to provide submarine capacity and terrestrial capacity obtained from multiple partners to offer a range of lower-priced world class Synchronous Digital Hierarchy (“SDH”) and Internet Protocol (“IP”) network transport services that are designed to meet the needs of a wide range of African Internet Service Providers (ISP’s),international carriers, content providers, large multi-national businesses and governments.
To do so, Moya Networks will issue its own cryptocurrency token which will act both as a fundraising method and an opportunity for early supporters to be directly involved in the project.


Moya Tokens (MTK) are ERC20 tokens based on the Ethereum blockchain. They will serve both as a fundraising mechanism that will allow Moya Networks to fund the purchase of ACE submarine cable capacity, terrestrial fibre capacity and fund the operations of Moya.
  
The Moya token will also grant the holder the right to receive 20% of Moya's profit on an annual basis. Any number of tokens (100%) sold at the end of ICO have a right to receive 20%of the company's profits on an annual basis.

Moya seeks to raise 6,000 BTC ,to purchase capacity rights in the Africa Coast to Europe Submarine Cable System (ACE). Moya will sell MTK tokens (MTK) over a 4-week period to the Cryptocurrency community. The MTK Token will be issued on the Ethereum platform. Bitcoin and Ethereum cryptocurrency will be accepted for purchasing MTK. Investors purchasing Tokens during the token sale will be eligible for bonuses.  

ICO Timeline:


- Pre ICO 1 Nov to *15th* Nov  (*30%* Discount)
- ICO Launch 15th Nov to 15th Dec

  • Fund Raise Cap: Max. 2,000
  • Accepted Purchase Methods: BTC & ETH
  • Native Blockchain: Ethereum (ERC20)
  • During the sale, MTK tokens will be offered at: http://moyanetworks.com

Distribution of Funds: The funds will primarily be used to purchase capacity rights in the Africa Coast to Europe Submarine Cable System (ACE) based on ACE-Moya existing contracts at the close of the ICO; to purchase backup capacity on the West Africa Cable System (WACS); and to purchase telecommunications equipment from qualified vendors; to install the equipment in the Moya backhaul network; and for the operations of the Company. Funds will also be used to pay personnel in the startup phase of the business.

Escrow Agents: TBD

 
Two Signatories will be assigned to the receive wallet (One from Moya and one Independent Escrow Agent). The release of funds requires two Signatures.
Funding Release Milestones:

  • 80% of the tokens sold will be directly released to crowdsale participants at the end of the crowdsale.
  • 20% of the tokens sold will be directly released for the purchase of additional submarine cable capacity, terrestrial backhaul capacity, marketing expenses, partnerships, team and employee expansion. Yearly access to investor company financials on request.

5  Alternate cryptocurrencies / Altcoin Discussion / CryptoCompare guide: An Introduction to ClearPoll on: September 29, 2017, 02:56:04 PM
An introduction to ClearPoll: https://www.cryptocompare.com/coins/guides/what-is-clearpoll/

The Problem

In recent times, the media, private organizations, and even governments have manipulated or censored true public opinion, to suit their agenda. The main problem is the centralization of public opinion poll data. Controlling the polls allows them to use it to their advantage, and does not give an accurate picture of what people really want.

The Solution - ClearPoll


ClearPoll is a social public opinion poll network, using blockchain technology to secure votes and poll results. The decentralized polls are not censored and cannot be manipulated. Users can easily download the app, search for topics that are important to them, and easily vote. They can then view detailed poll results and easily share the results. ClearPoll aims to be the place to go, to have your say. A hub of accurate, current public opinion across a wide range of topics including politics, human rights, entertainment, sports and more.

7  Alternate cryptocurrencies / Marketplace (Altcoins) / [BOUNTY] SuperNET Announces Bounties for BarterDEX GUI Development on: July 06, 2017, 08:51:14 AM

BarterDEX, formerly known as EasyDEX and/or InstantDEX, is a decentralised exchange that combines three key components: order matching, trade clearing and liquidity provider into a single integrated system that allows users to make a coin conversion request, find a suitable match and complete the trade using an atomic cross-chain protocol. Additionally, there is a privacy layer in the order matching so that two nodes can do a peer-to-peer atomic swap without any direct IP contact between the two nodes.

Supernet.org has recently announced a 10,000 Komodo and a $100,000 USD bounty for the development of a Graphic User Interface (GUI) for its BarterDEX exchange.

8  Alternate cryptocurrencies / Altcoin Discussion / Ethereum Classic Takes Stance Against 'Manipulative Crowdsale Tactics' on: April 27, 2017, 12:37:19 PM
"The Ethereum Classic development team has shared its opinion on what Nick Tomaino’s called, the “Irrational Appcoin Exuberance.” This exuberance is currently seen in Ethereum and may soon come to Ethereum Classic as more capital flows into the network.

Citing concerns regarding the way Initial Coin Offerings (ICOs) are structured in Ethereum and even within the Ethereum Classic network, the post seeks to caution investors against potentially risky investments in poorly planned or outright scam ICOs that can result in monumental losses for naive investors.

The post also showcases some examples where the Ethereum Classic community and dev team has performed its due diligence and warned against ill-conceived crowdfunding campaign on the ETC network, noting the different attitudes that the two competing blockchains, ETC and ETH, employ towards the Initial Coin Offering frenzy. The post reads:

'As one might expect, ETCDEV will not vouch for coin offerings in the same capacity as the Ethereum Foundation members who signed on as curators for the launch of The DAO crowdsale.'"

9  Local / Português (Portuguese) / Charlie Shrem: “Já não tem a ver com a tecnologia, tem a ver com poder” on: April 25, 2017, 09:00:58 PM


Charlie Shrem, empreendedor e co-fundador da Intellysis, esteve presente no episodio de hoje do programa Double Down, chamado “Does Block Size Matter?” com os habituais apresentadores, Max Keiser e Stacy Herbert.

Durante o episódio, Shrem expressou as suas opiniões relativamente ao debate de scaling ou como a Herbert o chamou “a Grande Guerra do Blocksize de 2017.” Shrem disse (traduzido):

“Na realidade, já não é um debate técnico. Toda a gente de ambos os lados da mesa dizem que a SegWit é a melhor tecnologia que temos.”...

11  Local / Criptomoedas Alternativas / Neos: A Tua Própria Web on: April 02, 2017, 09:51:37 AM

A Neos v3.0 está a chegar e esta versão traz muitas mudanças. A criptomoeda que era anteriormente conhecida pelas suas notáveis ferramentas presentes na carteira como o sistema de mensagens encriptadas, uma plataforma de trading (ligada à Bittrex) na própria carteira, suporte de múltiplas moedas, e mais, está agora a mudar os seus casos de uso e visão geral, aplicando o conhecimento e lições aprendidas nas versões anteriores.

A equipa por trás do projeto está agora a mudar o seu foco para fornecer um conjunto de serviços que são completamente descentralizados e que não dependem de nenhum serviço exterior que, de acordo com a equipa, “foi definitivamente o caminho errado” (traduzido).

O código inteiro da Neos está a ser trabalhado para fornecer uma fundação que vai servir os novos casos de uso enquanto mantém algumas das características chave da criptomoeda Neos, como o mecanismo de consenso Proof-of-Stake e a existência de uma rede de masternodes que fornece transações instantâneas e privadas.

O foco da Neos é agora servir tanto a audiência de criptomoedas como a mainstream ao oferecer acesso ao token Neos em si (e consequentemente às ferramentas da plataforma) sem ser necessária a intervenção de serviços terceiros ou intermediários como mercados de câmbio, faucets, e por aí fora. Esta característica cria a criptomoeda de entrada perfeita para novos utilizadores poderem começar a explorar a tecnologia blockchain enquanto e também uma rede social em que toda a gente tem a oportunidade de ganhar (e gastar) Neos.

Como é que a Neos consegue isto? Vamos ver...

12  Local / Português (Portuguese) / Bitcoin: O que é a SegWit? on: March 25, 2017, 04:11:42 PM


No sistema da Bitcoin, todas as transações são gravadas permanentemente na blockchain. É este atributo que permite à Bitcoin ser completamente descentralizada. No entanto, estas transações são compostas de dados que ocupam espaço nos blocos da blockchain. Estes blocos têm atualmente um limite de 1MB o que faz com que as transações estejam limitadas a 3-7 transações por segundo (TPS) tendo em conta que os blocos são emitidos de 10 em 10 minutos. Este limite de 1MB foi imposto de modo a evitar certos vetores de ataque que podiam ser explorados sem o mesmo. No entanto, devido à crescente popularidade da Bitcoin, este limite está a ser testado – Ler mais.

De modo a que este limite possa ser aumento existem várias propostas tais como o Bitcoin Unlimited e SegWit. Hoje, vamos tentar explicar o que é a SegWit, a solução proposta pela equipa de desenvolvimento, Bitcoin Core.

O que é SegWit

SegWit é a abreviação de Segregated Witnesses e é uma proposta apresentada pela equipa Bitcoin Core. Vem na forma de um soft fork, um upgrade compativel que pode funcionar mesmo se alguns utilizadores não fizerem update no seu software (Sem resultar numa divisão da blockchain). Foi lançada na versão 0.13.1 do Bitcoin Core.

Nas transações da Bitcoin existem três elementos chave. Quem envia, recebe, e as assinaturas (chamadas de testemunhas) e estas ocupam uma grande parte do tamanho da transação. Ao contrário da crença popular, a segwit não separa as assinaturas das transações...

Na sequência da batalha entre o Internal Revenue Service (IRS) e a Coinbase, uma startup decidiu tirar proveito da situação e criou um programa que ajuda os clientes a relatar impostos relativos a criptomoedas.

[...]

A app, chamada de Balance, foi lançada por uma empresa baseada em Nova Iorque que se dedica ao fornecimento de masternodes Dash, a Node40. Este software permite aos utilizadores calcular os ganhos e perdas nas trocas (câmbios) de criptomoedas e sincroniza-as automaticamente ao relatório de impostos 8949, que pode depois ser enviado para o IRS para ser analisado...

15  Local / Português (Portuguese) / Hard Fork: Bitfinex Emite Chain Split Tokens on: March 21, 2017, 05:20:44 PM


Após o crescente interesse na proposta da Bitcoin Unlimited, os mercados parecem estar já a preparar-se para a possibilidade de uma eventual bifurcação(hard fork) da bitcoin. A maioria dos mercados já emitiu declarações defendendo as suas posições, tendo a Bitfinex ido um passo à frente ao criar um “jogo” do possível hard fork.

Bastante semelhante a um mercado de previsões, a Bitfinex introduziu os Chain Split Tokens (CSTs), que, de acordo com Bitinex, é “o primeiro produto deste tipo”. Estes CSTs permitem que os clientes Bitfinex especulem sobre a possibilidade do hard fork acontecer ou não. Se você é um jogador ou tem um forte pressentimento/teoria sobre o próximo evento em torno da bifurcação da Bitcoin, então estes tokens podem ser para sí...

18  Local / Português (Portuguese) / Bitcoin Unlimited Atinge ~40% de Apoio on: March 13, 2017, 10:34:26 AM

Bitcoin Unlimited, uma das soluções de scaling propostas para a Bitcoin, atingiu os 39.6% de apoio num período de 24 horas durante a semana passada. Atualmente, BU tem mais de 30% de apoio durante o período de uma semana.


Bitcoin Unlimited é um client alternativo que visa aumentar a capacidade de transações da rede Bitcoin, que atualmente consegue apenas suportar 3-7 transações por segundo (tps), introduzindo um tamanho limite de blocos dinâmico.

A falta de capacidade na rede Bitcoin é uma situação urgente, sendo cada vez mais difícil/caro fazer uma transação de Bitcoin devido ao mercado de taxas que está a ser criado. Como os mineradores não conseguem processar todas as transações, as que têm taxas mais baixas são ignoradas e podem demorar horas ou dias a serem processadas...

20  Local / Português (Portuguese) / SEC rejeita ETF de Bitcoin on: March 10, 2017, 11:08:24 PM

A Securities and Exchange Commission (SEC) anunciou hoje que a ETF de Bitcoin foi rejeitada citando preocupações a nível de regulação como a razão principal, sendo que a ETF proposta pelos irmãos Winklevoss não é consistente com as regras que requerem que um mobiliário seja “desenhada para prevenir atos e práticas fraudulentas e/ou manipulativas e para proteger investidores e o interesse público.” No comunicado oficial, a SEC afirma:

“A comissão está a desaprovar esta mudança de regra proposta poque não considera a proposta consistente com a secção 6(b)(5) do Exchange Act, que requer, entre outras coisas, que as regras de um valore Mobiliário sejam desenhadas para prevenir atos e práticas fraudulentas e/ou manipulativas e para proteger investidores e o interesse público.”
A decisão por parte da SEC afetou o preço que desceu cerca de 10% em menos de 10 minutos. No entanto, o preço está agora a mostrar sinais de recuperação, tendo descido apenas 7% nas últimas 24h. A Bitcoin vale neste momento $1,095....
