BTCPay Server Payment Request: Invoice Clients and Get Paid in BTC by Sharing a Simple Link

The team at BTC Pay Server published an article introducing their Payment Requests feature.

It allows you to get paid in cryptocurrency just by sharing a simple URL using a new type of time-sensitive inoice page built into BTCPay.

BTCPay Server is an open-source cross platform, self-hosted bitcoin server compatible with Bitpay API.

Blockstream Explorer Updates
Blockstream published a few updates to its block explorer that was launched last year 2018. The most obvious of the changes is the enabling of address search with unlimited transactions. Although it takes more disk space, that has led to increased search speed for the explorer. Secondly, disabling Java Script has also been made possible to allow for more browsing privacy as Java Script can be used to remove anonymity of users especially those using Tor, to improve user experience significantly. Thirdly, an API endpoint and a web form have been added to enable transaction broadcasting, a feature that developers or users who may want to easily broadcast transactions to the Bitcoin Network may find useful.
Simple Proof of Reserves Transactions

Proof-of-reserve transactions are transactions provided by a certain custodian to prove ownership for an amount of funds. For example, lets say an Exchange currently holds 30 thousand Bitcoins on behalf of its users, if anything happens to the exchange, say a hack, the exchange might need to prove to its customers that their Bitcoin is in safe hands, currently any company that wants to perform a proof-of-reserve must do it in its own way and accordingly, their users have to understand the construction to be able to verify it, this makes the process not very common among custodian companies as it’s both tiresome and would require educating their users on technical terms.

A new BIP was proposed as a way to formalize a standard format for constructing these proofs, making it easier for custodians and users with existing wallet infrastructures to understand these proofs. Proofs are formatted as a regular Bitcoin transaction with small differences. This transaction must be unspendable as its sole purpose is to demonstrate the availability of the funds, not spending them. The proof must be linked to the issuer, preventing custodians from just copying other custodians’ proofs.

Proof of Stake Bitcoin Sidechains
Proof of stake is another consensus protocol that has been used on multiple block chains for quite some time now, there was a proposal on the Bitcoin-dev mailing list to attach proof of stake sidechains to the original Bitcoin blockchain. This allows for the development of decentralized networks which aim to manage reserves of Bitcoin, using custom application code and smart contracts that use Bitcoin as the native currency.
Bitmex Research Launched a Fork Monitoring Website
BitMEX research developed a fork monitoring tool that can be used to monitor network and protocol upgrades for soft and hard forks for Bitcoin and BitcoinCash. They plan to include different implementations of Bitcoin nodes such as Bcoin, BTCD and Libbitcoin which might be helpful to detect consensus bugs such as CVE-2018-17144 that was discovered last September. They also announced that the source code for the tool will be made available soon.
Braiins OS: Open Source Alternative to Bitcoin Mining Firmware
The company behind SlushPool announced the first release of its Open Source ASIC miner firmware called Braiin OS. Braiins OS is the very first fully open-source, Linux based system for cryptocurrency embedded devices. Now enabling AsicBoost. Finally, you know exactly what’s running on your device, have the ability to customize it in any way and benefit from major functionality tweaks enabled by a continuous development and updates.
