Project Goals
Provide a very simple website for sellers to be able to sell digital files and recieve BTC/BCH. Keep things bare minimal and nice UI. For complex features other websites like Rocketr,  Sellyg are available

Open source project so that anyone can launch their own digital good marketplace. Owner of website can earn revenue by charging commision from sellers while withdraw. Various features/enhancement can be added by any developer to differentiate their marketplace

Current Project Status

• File upload and link sharing working
• Payment screen for BTC working
• Payment received via Blockonomics API

Project Updates to be Done

• Buyer should be able to download files after payment
• Add support for withdrawing earned BTC
• Seller Dashboard with Statistics
• BCH support
• UI improvements and theme support

Calling Developers
We are looking for developers to contribute to the open source project and take it forward https://github.com/blockonomics/SatoshiBox. As mentioned, the project itself should be self sustaining in the future, as commissions from the sellers should give revenue. For initial push we have allotted a fund of 1000USD in BTC. This fund will be donated to developers with substantial/high quality Pull Requests to the repo as per discretion of blockonomics team

It has been 155 years since the emancipation proclamation yet we still see racism happening. In the past weeks, we have seen protests all across the globe demanding justice for George Floyd.

The Black population is at a disadvantage, and we need to be asking ourselves, how do we level the playing field. How do we tear down the systematic oppression that plagues America? Bitcoin can play a role.

Lightning network has made substantial progress and a number of merchants are now accepting lightning on their online stores. Most e-commerce websites will show a number of crypto options at checkout namely BTC/Lightning/Altcoins.

This creates a confusion among customers on which currency is more appropriate to send for payments. This article tries to address this below using a simple flowchart

So you created a bitcoin wallet, did a few transactions and are loving the cryptocurrency memes and financial freedom. Surely its time now to accept bitcoin payments on your online boutique!

Do you really need a bitcoin payment gateway ? Isn’t having a bitcoin address enough? Why use a custodial payment gateway for a currency meant to regain monetary control ?

 

The answer is NO. You don’t need to use a payment gateway to accept bitcoin payments on your website

The below article builds upon on how a merchant can create a bitcoin payment processor from scratch

Blockonomics offers a payment solution which is both decentralized and permissionless. Its platform is pushing the boundaries of what’s possible and it’s taking Bitcoin payments to the next level. Whether you are invoicing a client, running a successful online store, or gathering funds for a charitable cause, Blockonomics has focused on allowing you to accept Bitcoin directly.

A personal favorite of mine is the ability to generate P2P invoices straight from their homepage. All you need is a Bitcoin wallet address and you’re good to go. As an online entrepreneur and cryptocurrency enthusiast, you can understand why I would find this feature so useful. If you’re in the same boat, now you know you can keep easily invoice anyone — no need to go through PayPal invoices again.

Experience the Future of Digital Payments with Blockonomics

Founded in 2015, Blockonomics has helped thousands of retail businesses to provide cryptocurrency payment options to shoppers. The firm is among the first businesses to equip retailers with advanced invoicing tools and offer free-of-cost plugins to keep up with customer demands.

Their service enhances the wallets you already own. The payment lets you accept Bitcoin payments on your WHMCS installation with ease. There are no security risks; payments go directly into your own bitcoin wallet. The complete checkout process happens within your website; customers never leave your site.

To fuel the demand, Blockonomics is issuing BCK tokens, which enables support to BCH, LTC, and ETH and Lightning Network integration. In a significant move, the company is integrating Wix and Shopify payments on its platform.

Moreover, it sends API with Multi-signature wallet. These tokens provide various perks to customers too.

Blocknomics to Drastically Expand Bitcoin Ecommerce Implications

To further their mission in supporting Bitcoin as the #1 currency for e-commerce, Blockonomics will undergo an ICO. With funding from the ICO, Blockonomics will be able to expand their services provided to encapsulate a range of benefits and services to merchants utilizing the platform.

According to the road map, these services will first consist of integration with a number of e-commerce solutions: Shopify, Wix, OpenCart, and more. These integrations are slated for September of this year.

In maintaining their role as a pioneer of Bitcoin e-commerce, Blockonomics is also looking to integrate Lightning Network functionalities to merchants on its platform. Lightning Network enables fee-less, instantaneous microtransactions. Beyond this, Blockonomics also seeks to enable zero confirmation payment, where the Blockonomics API can detect double-spend attempts without the need for miner confirmation. This will enable similarly instantaneous transactions on large payments that do not take place on Lightning Network.

ICOs have already raised 4.4 billion USD in 2018 (Source), and we are yet to complete half of the year. The traditional VC funding model has been disrupted and you need not fly half way around the world to pitch investors in close door meetings in Silicon Valley to raise funds. The above article summarizes  how you can accept bitcoin for your ICO.

Hi,

We are developing a project similar to https://bitcoinfees.earn.com/ . We know that bitcoinfees is giving widely inaccurate results. We need to develop a algorithm that can predict confirmation time with reasonable accuracy (or atleast better than bitcoinfees)

Factors that can taken into consideration:

- Mempool size
- Hashrate
- Rate of incoming transactions


Let me know your thoughts on this. If you have any ideas on the algorithm. I am open to keep this opensource(directly connected to bitcoind).

Hi,

Blockonomics is pleased to announce full segwit support in  blockexplorer, invoicing and merchant solution

Feel free to try it out. Let me know if you have any suggestions/feedback

[Breaking backwards compatibility]

This thread proposes changes to BIP49 to address segwit compatibility issues

Breaking backwards compatibility
The BIP talks about breaking this, and  but it really doesn't.  I really feel it should completely break this. Here is why

What would happen if you recover a wallet  using seed words ?
  1. Since there is no difference in seed words between segwit/non segwit, the wallet would discover both m/44' and m/49' accounts
  2. Note that we cannot ask the user to choose an account he wants to operate on (Segwit/Non segwit). This is like asking him the HD derivation path and a really bad UI
  3. The wallet now has to constantly monitor both m/44' and m/49' accounts for transactions
  
Basically we are always stuck with keeping compatibility with older seed words or always asking the user if the seed words came from segwit/non segwit wallet !

Here is my suggestion :
1. By default all new wallets will be created as segwit  m/49' without asking user anything. I think you would agree with me that in future we want most wallet to be default segwit (unless user chooses a non segwit from advanced options)!

2. Segwit wallet seed words have a different format which is incompatible with previous wallet seed words. This  encodes the information that this wallet is segwit in the seed words itself. We need to define a structure for this


XPUB Derivation
This is something not addressed in the BIP yet.

1. Right now you can get an xpub balance/transaction history. Now there is no way to know whether an xpub is from m/44' or m/49'

2. This breaks lots of things. Wallets like electrum/armory/mycelium support importing  xpub as a watch only wallet. Also services like blockonomics/blockchain.info use xpub for displaying balance/generating merchant addresses

Looking forward to hearing your thoughts. Please advise and I can create a PR encompassing your suggestions.
