The innovation speed in Blockchain landscape is just breathtaking and being able to (or to be honest trying to...) follow all these rapid changes is a chance for all software engineers.
At the core of the Blockchain disruption are consensus algorithm:
Consensus algorithms enable network participants to agree on the contents of a blockchain in a distributed and trust-less manner.
And the consensus algorithm plays a crucial role in maintaining the safety and efficiency of blockchain. Using the right algorithm may bring a significant increase to the performance of blockchain application.
But do you know how much consensus type are out there? or where they are applied? my new Consensus Map may help you there exploring the always evolving landscape:
Here is the actual Consensus list: DPoR, DPoS, DPoS/LPoS, FBA, HPoW, LFT, Limited Confidence Proof-of-Activity, Ouroboros, POBh, PoA, PoB, PoB/PoS, PoC, PoI, PoP, PoP/PoV/PoQ, PoPP, PoR, PoS, PoS/LPoS, PoS/PoB, PoS/PoD, PoS/PoP, PoS/PoW, PoS/PoW/PoT, PoST, PoSign, PoW, PoW/DPoW, PoW/HiPoS, PoW/PoM/PoSII, PoW/PoS, PoW/PoS/PoC, PoW/PoSC, PoW/PoZ, PoW/nPoS, PoWT Proof of Believability, Proof of Existence, Proof of Ownership, Proof of Time, Scrypt-adaptive-N (ASIC resistant), TPoS, Tangle, dPoW/PoW, mFBA
You can filter by any type of Consensus and zoom, learn more about them by hovering over the menu.
The map also feature a mode selector at the bottom, if you switch to Algorithm Map you'll see where each of the 82 cryptographic algorithm are used!
The Map will be auto-magically regenerated every week on Sunday evening. The tedious task of maintaining the list of all Consensus algorithms (I've documented 60+ but only 47 are represented) and their descriptions are (still) maintained manually.
More filters will be added soon (showing for example only the top 100 by market cap, consensus by date of creation, and so on...), and your feedback is always welcomed.Add comments

Ever since Vitalik Buterin and Ethereum settled on Switzerland for its Foundation and Initial Coin Offering (ICO), Switzerland has been popular among blockchain-based businesses and is considered the number one in a list of the top 10 European countries for starting a blockchain company (source cointelegraph.com).
PwC also found that ICO volume reached new record highs in the first half of 2018 ($13.7 Billion so far), already doubling the volume of the previous year! That inspired me a way to compare at the same time the volume, the categories and amount raised for all these ICO in an interactive and fun way.
Thanks to D3js library and IcoBench.com the development was done in a new record time! but let me present the results for the most blockchain-friendly countries Switzerland – Russia – Singapore – USA - Estonia - Germany
You can explore all charts by zooming, panning and hovering over each bubble. Note that I did only consider ICO which are ended, most countries have a consequent number of ongoing ICO (more than 60 ICO ongoing in Switzerland!).
Feedback is always welcome, use comments or ping me your remarks.Add comments

Business Model Canvas is a strategic management and lean startup template for developing new or documenting existing business models. It is a visual chart with elements describing a firm's or product's value proposition, infrastructure, customers, and finances. It assists firms in aligning their activities by illustrating potential trade-offs.
Business Model Canvas: nine business model building blocks, Osterwalder, Pigneur & al. 2010
After reading this great article https://medium.com/@pstehlik/evaluating-blockchain-projects-with-token-economy-canvas-908bc1bab6 I felt the need to create an online editor.
"Token Economy Canvas consists of nine building blocks that are filled out in a pre-defined order. Answering the questions for each building block helps gain insight into each aspect of a blockchain project and its token. Combined, the answers allow a holistic view of the proposed token economy. From there you can make your own decision on the viability of a token or how it relates to a possible evaluation of a project. "
The tool save regularly all your entries into browser Local Storage, so it will restore them after browser crashes, tabs closings and other disasters.
If you agree to tick the checkbox to share, all your data will be persisted to the server, in a format that later allow the Blockchain community to query, compare and read token canvas (these features are in development).
As a bonus, i also provide an excel template. Visit https://canvas.tokens-economy.com/ now :-)Add comments

Do you want to relocate your Blockchain company to an ICO friendly country? the ICO friendliness rating index is a interactive way to go through the list of countries that are hostile or favorable to ICO and Cryptocurrencies.
Attention! a disclaimer is required:
No Legal Advice or Attorney-Client Relationship: This chart is provided for informational purposes only and is not legal advice. This information is not intended to create, and receipt of it does not constitute, an attorney-client relationship. Recipient should not act upon this information without seeking advice from a lawyer licensed in his/her own state or country.
I've created the ICO-Rating Index, a number (0-5) that represent how friendly a country is toward ICO and Cryptocurrencies in general. It can have the following values:
- unknown (0),
- prohibited (1)
- mostly unfavorable (2),
- mostly favorable (3),
- favorable (4),
- legalized (5).
All maps are generated every 12 hours automatically. Official sources or link to online rating are always provided.
Switzerland hosts the fourth highest number of ICOs, after the U.S., the U.K., Russia.
The US Security Exchange Commission (SEC) is currently trying to categorize Cryptocurrencies, and landscape will changes a lot in the coming months. In between you can still apply the Howey Test (online test) to distinguish in which category your token apply. Your token can be either a Utility token or a security token:
Utility tokens, also called user tokens or app coins, represent future access to a company’s product or service. The defining characteristic of utility tokens is that they are not designed as investments (if properly structured)
If a Crypto token derives its value from an external, trade-able asset, it is classified as a security token and becomes subject to federal securities regulations. Failure to abide by these regulations could result in costly penalties and could threaten to derail a project. However, if a startup meets all its regulatory obligations, the security token classification creates the potential for a wide variety of applications, the most promising of which is the ability to issue tokens that represent shares of company stock.
https://ico.tokens-economy.com display in an entertaining way the state of ICO worldwide legal framework and will be a work in progress for the next months to come.

You can watch channels using any software or device as long as it supports multicast. Such as VLC on a computer. A VLC playlist with all TV7 channels and the multicast addresses is provided for this under the following link:
You have the following options:
- You open the URL directly from within VLC (Open -> Network and then paste the URL from the above link), so you always have the latest updated channel list.
- Download the file to your computer and open it in VLC.
- Download the file to your computer and open it in a text editor to search for the respective multicast addresses of channels to use with another box or program that does not support XSPF playlists.
Note that the multicast addresses of individual channels and the channel line-up may change. so it is recommend to use option 1.
Unfortunately this was not working for me at all, I use VMWare and Virtual Box, and both software define custom network adapter...
somehow vm network adapter do not set properly the automatic metric. The fix is to change the IPv4 metric to 1 on the physical ethernet (or wireless if needed) and leave the other to automatic.
