New Qtum.info Explorer Features

https://blog.qtum.org/new-qtum-info-explorer-features-e4bf8c70f4ed

New features in the powerful Qtum Explorer including network overview, staking page, transaction types labeling and subscriptions.

This Explorer user interface refresh is the latest update in HMI (Human-Machine Interface) from the Qtum graphics designers and user interface developers using colors, fonts, and icons to represent relatively complex blockchain data. But don’t let the pretty pages fool you, this Explorer is a sophisticated blockchain “power tool.”

Development Updates (January 27 - February 02)

https://qtum.org/en/post/development-updates-january-27-february-02

Qtum Core

Qtum core updates normally consist of Qtum Improvement Proposals. These QIPs are generated by both our developers and the community and in some cases requests from enterprise users. Our developers evaluate the impact of each QIP and work on high priority QIPs. All bug fixes and feature enhancements that have been issued to the core project will be listed here.

•    Continue port Bitcoin 0.19.0.1 to Qtum
•    Preliminary design specification and QIP for Qtum offline staking
•    For information of Qtum Hard Fork please refer to: https://link.bar/qtumhardfork

Qtum Neutron & x86 Virtual Machine

Qtum Neutron is the infrastructure to support new virtual machines and the first will be the x86 virtual machine allowing smart contract development in C, Rust and other languages. The EVM will continue, but the x86 VM will allow easy creation of smart contracts using safe, well-known, mature languages and tools, and also provide a new state memory model using DeltaDB.

•    rcr, rcl, ror, rol implemented
•    sar implemented
•    Clear and set and complement flag ops implemented
•    xlatb complete (code implementation: https://github.com/qtumproject/qx86-rs/pull/57)

Web Wallet

•    No update for this week

Qtum SDK

QtumJ is BitcoinJ ported to the Qtum blockchain protocol. The BitcoinJ library is a Java implementation of the Bitcoin protocol, which allows it to maintain a wallet and send/receive transactions without needing a local copy of Bitcoin Core. It comes with full documentation and some example apps showing how to use it.

Why Electrum wallet synchronizing stops many times , I have to reopen it for continue sync 

[JB395]

flyx: Why Electrum wallet synchronizing stops many times , I have to reopen it for continue sync  Huh

Are you using a VPN? Electrum is sensitive to VPN settings and perhaps if there are national restrictions/filtering on the Internet. Some users report success using Tor with Electrum.

(I would send you a message if you allowed them from newbies)

[Karto]

where can i find information about projects that build on QTUM or partnerships?
i see Algorand for example working with some entities to bring solutions , but i can't see much activity in QTUM
maybe its because its chinese?
in other hand its being listed almost everywhere
im a little confused about this coin, invested a little amount a long time ago and still holding
im -50% thinking about what to do next

[JB395]

Hey Karto,

Linked below is a chart from 4Q 2019 showing Qtum uses. Besides these, some DApp/token projects pivoted or are still hibernating from the crypto winter. Probably the most active QRC20 token project currently is QC, a stable coin based on the Chinese Yuan https://www.quickcash.com/qc

Use Qtum https://i.imgur.com/xMH7TLo.jpg

I use VPN often , and why national restriction ? Is it possible ? I think the main theory behind creation of cryptocurrencies was get rid of borders and governments who want control your life

[JB395]

You can do a Google search for suggestions about using Electrum with VPNs, which is a common issue with Electrum. Or turn off your VPN when using it.

I’m guessing that countries that filter or restrict the Internet could also cause problems for Electrum. If you live in such a country, you probably know about this.

Decentralized permissionless blockchains would have less problems with VPNs and other restrictions. But think about the Electrum lite wallet architecture connecting to a server somewhere. If traffic to that server is restricted it may not work so well.

Blockchain Developer Acronyms: What Do They Mean?

https://blog.qtum.org/blockchain-developer-acronyms-what-do-they-mean-f395125b5a00

The command-line interfaces (API, CLI, RPC) provide granular low-level control of all the commands for the Qtum node. The GUI wallet (Qtum-Qt) exposes most of every day commands through a graphical interface. But developers and stakers can use these command-line tools for everything else, and we see how.
