Bitcoin is a cryptocurrency invented in 2008 by an unknown person or group of people named Satoshi Nakamoto and launched in 2009 when its implementation was released as open source software.

Bitcoin has received high praise and criticism. Critics have noted its use in illegal transactions, the large amount of electricity used by miners, price volatility and theft from exchanges. Some economists, including several Nobel laureates, have described it as a speculative bubble. Bitcoin has also been used as an investment, although several regulators have issued investor warnings about Bitcoin.

Samourai Wallet – Anonymous Mobile Bitcoin Wallet (Download for IOS & Android)

Download Samourai Wallet:

Samourai Wallet – A modern Bitcoin wallet designed to ensure the confidentiality of your transactions, mask your identity and protect your funds.

The main advantages and advantages of Samourai Wallet over other mobile wallets:

  • Full offline mode
    • Samurai works in any network environment. This is an attractive option for those who are interested in creating highly reliable cold storage systems, as well as for those who are in adverse conditions or in conditions that limit the cost of the network.
  • Segregated Witness
    • Segregated Witness – This is a recent update to the Bitcoin network, which helps keep miner fees at the lowest possible level when making deals. Samourai Wallet was one of the first to support SegWit, which allowed users to create efficient transactions to keep miner fees as low as possible.
  • Smart Miner Fees
    • Smart Miner Fees – it’s the cost of doing business on a bitcoin chain. They are an incentive for the miner to add your transaction to the block, as well as a mechanism for preventing spam. The Samurai wallet has a best-in-class miner reward rating to help you quickly confirm your transactions without overpaying.
  • Dojo
    • If you do not manage your own complete host, at some point you trust someone. Until now, it was difficult to launch your own full-fledged node and still use a mobile wallet. Dojo changes everything
  • STONEWALL
    • Most bitcoin wallets reserve metadata that chain supervision firms use to deanonymize you. STONEWALL helps protect against address clustering deanonymization attacks.
  • PayNym
    • When you publish your regular address publicly, you provide the supervisor with a starting point to track you. PayNyms protects against this type of “first touch” attack by never revealing the address to anyone other than the sender and receiver of the transaction.
  • Batch Spending
    • Batching is a way to compose a single transaction that contains many unrelated transactions. This can be beneficial when the fee for the miner is high, and you need to complete several transactions at a certain point in time.
  • Scrambled PIN
    • The PIN access screen is randomly displayed at every boot and does not provide visual feedback to prevent spy screen recording and other common attacks.
  • Stealth Mode
    • Stealth Mode removes Samourai from the launchpad and home screen of your Android device. To open the wallet, just type the secret code.
  • Remote SMS Commands
    • Remote SMS commands are included and allow you to remotely erase and restore your wallet via SMS in case of loss or theft of the device.
  • Ricochet
    • Switch Ricochet when sending to third-party exchanges or services, such as Coinbase, Gemini, ShapeShift or Localbitcoin, to significantly reduce the risk of unjustified account closure by these services.
  • Whirlpool
    • When you alternate your coins in Whirlpool, you break the connection between the inputs and outputs of your bitcoin transactions. Use all your bitcoins for more privacy.
  • OpenDime supported
    • OpenDime is a standalone USB hardware wallet. Samourai Wallet supports reading from OpenDime without having to access private keys. It can also sweep the balance from OpenDime with a public private key.

History of MANO Coin (MANO)

In December 2018, it was announced that the original developers abandoned the project, leaving the half-completed project and a thriving community behind. In January 2019, a small group of community members began planning for community adoption of the project. They obtained most of the assets from the initial project and attracted a number of community members with the appropriate skills and experience to complete the project. Developers, to build a platform, create a blockchain and automate physical servers, come together to restart a project, bigger and better than before.

Gincoin Core

GIN описывает себя как проект цифровой валюты с открытым исходным кодом, целью которого является предоставление безопасных децентрализованных финансовых решений. Грузовой флот мастер-узлов GINcoin (GIN) доставляется по протоколу GIN Ecosystem Apps (GEA). Протокол GEA, как сообщается, представляет собой набор правил, применяемых DAM (рынком распределенных приложений) и фрахтовщиками для создания и мониторинга децентрализованного грузового флота. Фрахтовый флот GIN предназначен для поддержки работы распределенных приложений или заданий в децентрализованной системе, которая стремится быть устойчивой к отдельным точкам отказа и контроля.GIN describes itself as an open source digital currency project whose goal is to provide secure, decentralized financial solutions. The cargo fleet of GINcoin master nodes (GIN) is delivered using the GIN Ecosystem Apps (GEA) protocol. The GEA protocol is reported to be a set of rules used by DAM (the distributed application market) and freighters to create and monitor a decentralized cargo fleet. The GIN freight fleet is designed to support distributed applications or jobs in a decentralized system that seeks to be resistant to individual points of failure and control.

As reported, the GIN platform is the first organization to adopt the protocol and participate in the creation of the first DAM, which requires its customers to deploy master nodes and will benefit from a distributed network of hosting providers. GIN is the main currency for the GIN platform and provides transaction and management support through the GIN master nodes.

GINcoin is a coin of the GIN Masternode system, which is used for simplified deployment of masternodes (currently it is used in coins SmartCash, ALQO, Horizen, Bulwark, Polis and many others). The price for a month of using the GIN Masternode cloud node is from $ 4.5 per month.
