changed the deprecation height calculation to factor in the new block time of 1.25 mins
What is ZClassic?
ZClassic is an implementation of the “Zerocash” protocol. Based on Bitcoin’s code, it intends to offer a far higher standard of privacy through a sophisticated zero-knowledge proving scheme that preserves confidentiality of transaction metadata. Technical details are available in our Protocol Specification.
This software is the ZClassic client. It downloads and stores the entire history of ZClassic transactions; depending on the speed of your computer and network connection, the synchronization process could take a day or more once the blockchain has reached a significant size.
ZClassic is experimental and a work-in-progress. Use at your own risk.
📒 Deprecation Policy
This release is considered deprecated 16 weeks after the release day. There is an automatic deprecation shutdown feature which will halt the node some time after this 16 week time period. The automatic feature is based on block height.
Getting Started
Building
Build ZClassic along with most dependencies from source by running:
Clone the repository
git clone https://github.com/ZclassicCommunity/zclassic.git
cd zclassic

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.
Use all wallets with caution. You should never share private keys, seeds or wallet files with anyone.

MANO: Masternode is an advanced Masterndoe hosting platform with many features that allow users to easily host a variety of master sites. MANO’s mission is to provide Masternode’s passive income opportunity to a larger audience. We hope that by removing the barrier to entry for many, it is possible to achieve widespread adoption of blockchain technologies.
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.
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.
GINCOIN cryptocurrency features
from February 15, 2019 at 16.00 GMT, the GINCOIN blockchain operation is based on the PoW x16rt algorithm (before that – PoW Lyra2Z), in addition, the PoS masternode system is used;
time between blocks – 2 minutes;
block reward – 20 GIN coins (until block 262800 – March 2019), which are divided equally between miners and masternode owners;
the developers implemented a premine of 4% (420 thousand GIN coins);
GIN coins are issued and rewards are distributed to miners and masternode owners according to the following plan:

What it the «CoinJoin»?
The mechanism by which several participants combine their coins (or, to be more precise, UTXO) into one large transaction with several inputs and several outputs. The observer cannot determine which output belongs to which input, as well as the participants themselves. This makes it difficult for third-party organizations to keep track of where a particular coin was received from and where it was sent to (unlike normal bitcoin transactions, where there is usually one sender and one recipient).
This can be done using non-storage software such as Wasabi, which eliminates the risk of extinction or theft of funds. Each of the signatures is created on the computers of the participants, so anyone who tries to connect the signatures cannot change the transaction or redirect funds. The funds will always be located at the Bitcoin address that you control.
This can be done in a decentralized way so that the service does not depend on external parties or centralized servers. It is simply necessary for the parties to the transaction.
CoinJoin can be applied several times, and since many transactions are grouped, participants can save on transaction fees. CoinJoin is the preferred method of gaining privacy on the Bitcoin network.
CoinJoin means: “when you want to complete a transaction, find someone else who also wants to complete the transaction and complete the joint transaction together.”
Launched in 2017, Electroneum (ETN) is a mobile cryptocurrency that uses blockchain capabilities to unlock the global digital economy for millions of people in developing countries, with an emphasis on creating a real ecosystem with additional products such as AnyTask.com, ETN Everywhere, Taskschool and ETN Donate.
Electroneum uses a cryptographically sound system that allows you to send and receive your tokens, while your transactions will not be easily detected on the blockchain. This ensures that all token transfers remain completely private by default, but can be verified by a third party if necessary by providing certain keys.
Safety. Using the capabilities of a distributed peer-to-peer consistent network, each transaction in the network is cryptographically secure. Individual wallets have a mnemonic starting number of 25 words, which is displayed only once and can be recorded for wallet backup. Wallet files are encrypted with a passphrase to ensure they are useless if they are stolen.
Electroneum (and its group of companies) have developed proprietary software that can be used in conjunction with this project. This software is subject to the individual terms and conditions that are available at https://electroneum.com.
The V8 software update (Electroneum v3.0.0.0 release) made some fairly radical changes to the Electroneum blockchain, consisting of a new agreed-upon algorithm, which we called the “Proof of Responsibility”, and changed it from a completely undivided blockchain to a moderated one. Blockchain
The moderated blockchain, based on the Proof of Responsibility consensus algorithm, allows Electroneum Ltd to better control the blockchain, while maintaining a good degree of decentralization. Ultimately, this increases our security by making the commercial and economic blockchain model more attractive. In addition to these basic functions, we have included several small changes that contribute to the functionality and scalability of the blockchain.
Electrum Wallet – This is a lightweight digital wallet for bitcoins. Its main feature is speed, appropriation, low resource use and simplicity. It starts instantly, as it works in conjunction with high-performance servers that handle the most complex tasks of the Bitcoin system.
Due to the fact that Electrum uses the method of simple payment verification (SPV), the application can remain easy. The SPV client does not need to download a complete transaction chain. He only needs to download block headers, which are much smaller than full blocks. Which makes it much faster and more convenient to conduct operations with cryptocurrency.
Electrum has various user interfaces: it can be installed on mobile devices, on the desktop or using the command line. Electrum supports hardware wallets: Ledger, Trezor, Keepkey.
This wallet has its own portable version, which makes Electrum a hardware wallet. The password and other protection applications are transferred to a regular flash drive, where they are stored remotely from the computer. When there is a need to send a transfer, a USB flash drive is simple enough to connect to a PC.
How to install and use Electrum
Step 1. Download the correct version for your operating system.
Step 2. Run the program and in the window that opens, come up with a name for your wallet:
Step 3. Indicate what action should be performed:
create a standard wallet;
associate a wallet with 2FA;
bind multicurrency storage;
import the address of a bitcoin wallet or private keys.
Choose “Standard wallet”.
Step 4. Create a secret Seed phrase, which will be needed to restore access to the wallet if necessary.
Step 5. Now you need to select the type of storage. It’s better to choose Segwit, as this wallet option has several advantages: it is completely free and has limited transactional paid programs.
At step No. 6, a secret phrase will be generated from 12 unrelated words, which must be carefully and responsibly kept in a safe place. You can print it, copy it or take a picture. It is important that no one can use it without your knowledge.
To proceed to the next step, you will need to enter this Seed phrase correctly.
Step 7. To protect yourself from malware and unauthorized access, you need to encrypt your wallet with a strong password.
Step 8. After installation, it is recommended that you export your private keys for secure storage. Your secret key is your access to cash and all bitcoin transactions. Never give these keys away and keep them as safe as possible. Private keys can be exported through Wallet -> Private keys -> Export.
That’s all – now your wallet is created and ready to use.
How to use Electrum wallet
The wallet interface looks like this:
It has four tabs:
story;
send;
receive;
addresses.
Storage management is quite simple and intuitive.
The History tab displays all transactions of this wallet.
On the “Send” tab, you can create outgoing transactions with bitcoins and determine the size of commission payments.
On the “Receive” tab, you can request a payment with a QR code for payment.
The “Addresses” tab displays all the bitcoin addresses that are associated with the storage.
How to regain access to the wallet
If for some reason you have lost access to your repository (you forgot your password, stole the gadget, a software client is broken, etc.), you can easily restore it. To do this, you will need a secret Seed phrase that you saved in step 6 of the installation.
Run the program file. As you can see, Electrum supports various types of wallets. You need to choose the same type of wallet that you are recovering, in this example it is a “standard wallet”.
At the next stage, Electrum will ask you to choose where the wallet’s secret will be. Select “I already have a seed.”
Then enter your seed words:
When you enter the correct seed words, the next button will become active, and you can proceed to the next step.
Note. If the seed words are taken from another wallet, such as the blockchain.info or Mycelium wallet, you need to press “Options” and check bip39. If your seed words are taken from bip39 wallet (i.e. not Electrum), you will see this window below. Just leave the default value (m / 44 ‘/ 0’ / 0 ‘) unchanged and click Next.
Now Electrum asks you to enter a password to protect your wallet file. This action is optional, but highly recommended.
Conclusion
Electrum – This is a very reliable, well-protected option for storing bitcoins. There are several versions of the wallet for other cryptocurrencies, the official ones are only Bitcoin-Electrum, Dash-Electrum and Verge-Electrum.
It is quite popular among users. It is easy to install and very simple to manage. Electrum combines all the advantages of cold storage of cryptocurrencies with ease of use online. The application does not burden itself with a heavy blockchain, but refers to it only to update information.
Here are the main benefits of using an Electrum wallet:
all private keys of the vault are located remotely from the server and are never transferred to third parties;
the application is lightweight and does not take up much space on your device;
a project that can run on various operating systems (Windows, Linux, OSX, Android) and supports integration with hardware wallets (Trezor, Ledger, KeepKey);
the wallet has a high degree of security and an acceptable level of anonymity;
the ability to create highly secure wallets using the TrustedCoin service (2FA, multi-signature).
Among the disadvantages of Electrum are the following:
Paid sets of one-time passwords for the two-factor authentication function (in terms of translation it turns out somewhere around 0.00005-0.0001 BTC for each confirmation);
