[ANN] (QTUM) - A Scalable Smart Contract Platform w/ Proof of Stake

[thefix]

Very cool program, just setup a node on a vps and realized I am late to the party for the Global Full Nodes Incentive Program. My fault for not looking more closely at the dates

I might as well leave the node up for a month since I set it up

Wishing everyone much luck with this project

The Road to Offline Staking — Part 3 — Super Staker Wallet Weight

https://blog.qtum.org/the-road-to-offline-staking-part-3-super-staker-wallet-weight-c5ae6d2c5edd

From the previous blogs in this series, you should be aware that the Super Staker provides Proof of Stake services for delegated addresses and stakes its UTXOs when it wins a block reward for the delegated addresses in Qtum’s Offline Staking protocol.

This means the Super Staker must have its own inventory of UTXOs ready to be staked, and locked in a stake for 500 confirmations (blocks). For a Super Staker managing a large number of delegated UTXOs, how many UTXOs should it hold for staking? If the Super Staker has all its UTXOs committed to stakes it will stop staking and can’t win any block rewards.

TL;DR For Qtum Offline Staking, the Super Staker must have enough UTXOs to stake proportional to the Delegated Weight it is staking. A simulation shows the appropriate Wallet Weight for various Super Stakers, for example, with a Delegate Weight of 5% of Network Weight, the Super Staker should have a Wallet Weight of 15,000 QTUM.

•     Began design documents on how Neutron will be integrated into Qtum
•     Designed major portions of the AALv2 which will be built to support Neutron, with many improvements thus far over the current AAL including fixing the user visible annoyance of gas refunds requiring 500 blocks of confirmations before a user can spend them.

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.

Qtum Super Staker: Easy Setup Guide

https://blog.qtum.org/qtum-super-staker-easy-setup-guide-e81afdd1eaac

A step-by-step guide on setting up the Qtum Core wallets Qtum-Qt and qtumd as a Qtum Super Staker!

Qtum Core version 0.19.1 provides an update for offline staking using the wallet as a super staker, providing staking for delegated addresses. Qtum Testnet completed its hard fork with block 625,000 at 9:50 am GMT on June 29, 2020, and is now available for testing of the new offline staking protocol.

This blog shows how to set up a super staker on Testnet in 6 easy steps. A full explanation of these steps is given in the references. Read more: https://blog.qtum.org/qtum-super-staker-easy-setup-guide-e81afdd1eaac

Development Updates (July 14 - 20)

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.

•      Qtum Core v0.19.1 Mandatory Update

Infrastructure for Qtum

•      Continued work on Janus

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.

•      Continued work on Neturon
