Blockchain Technology

What is blockchain?

The block chain is a database of information. This information is not stored in a single place, but across a variety of data servers that participate in the network, this is what is meant by “decentralized” there is no central point. Identities are kept completely private, through the cryptography, however all transactions that happen on the block chain are open to viewing by anyone at any tie for always.

Trust in the block chain is enough to transact with anyone. Every record that’s written on a block chain is secured by a unique cryptographic key, making the block chain and it’s information immutable.

How Does a Block chain Work

  • A user requests for a transaction
  • A block representing the transaction is created
  • The block is broadcast-ed to all the nodes of the network
  • All the nodes validate the block and the transaction
  • The block chain is added to the chain
  • The transaction gets verified and executed

How to create a blockchain transaction?

  • When 2 parties initiate a transaction, blockchain assigns an encryption
  • Blockchain verifies the transaction and creates a block
  • The new block is appended to the blockchain
  • The blockchain transaction is now complete and the ledger is updated

Blockchain Checklist

  • Database: Block chain is a unique shared database technology. A block chain project must use a structured data repository
  • Mistrust: Block chain implies multiple non-trusting writers. They don’t allow other users to modify their entries.
  • Interaction: The block chain transactions often depend on another writer’s transactions created collaboratively without exposing the parties to risks
  • Writers: Block chain relies on multiple writers who generate transactions modifying the database
  • Disinter Mediation: No central gatekeeper needed to verify transactions and  authenticate their sources
  • Rules: The database is modified by various non-trusting writers. It must contain integrated rules that restrain the transactions and define legitimate transactions.

7 Ways the blockchain can help the environment

  • Environmental treaties:  Track real impact and compliance of environmental treaties decrease fraud and manipulation
  • Non-Profits: Track where donations are going decrease inefficiency and bureaucracy in charities
  • Carbon Tax: Calculate tax for products based on carbon footprint create a reputation system for companies based on emissions
  • Changing Incentives: Align incentives with sustainable practices create incentives for people to act in sustainable ways
  • Supply Chains: Transparently track products from origin to store shelf reduce carbon footprint and unsustainable practices.
  • Recycling: Encourage recycling by providing tokenized reward track and evaluate efficacy of recycling programs
  • Energy: Increase efficiency with P2P electrical grids improve access to power in areas with poverty or natural disasters.

WiFi the Silent Killer

According to some studies made by “the telegraph”, exposure to wireless waves interfere with the human body and can create problems such as: Short term memory loss, Lethargy, Cardiac problems, Sleep disturbance.




In previous post we describe about Evolution of 5G Technology

WiFi Radiations

Wireless Internet routers or WiFi modems use dangerous electromagnetic radiation to send their signals to your computer through walls. If you have a wireless internet router set up in your home or office you are receiving massive EMF exposure, and living or working in a dangerous soup of radiation.

Not only atmospheric + ve charges, the wireless WiFi devices + cell phone radiation and the static electricity but also other pollutants.

Reduce your WiFi Radiation

We know that some people can’t quite bring themselves to surrender their wireless devices so here are some tips on reducing Wifi radiation.

  • Keep your distance : WiFi radiation drops off significantly with distance. many routers have a strong enough signal to maintain a connection up to 100m from the router.
  • Switch off at Night : Studies tell us that the biggest danger with WiFi radiation comes from nighttime exposures; cellular regeneration, rejuvenation, and detoxification is impeded and notably melatonin production can be significantly reduced.
  • Use USB Adaptors wisely: If you are use a USB WiFi adapter use it on a USB extension cable. The same goes if you use a 3G USB dongle to connect to the internet wile you are traveling, an extension cable will significantly reduce your exposure.

The dangers of WiFi are real. Use the above tips to eliminate or reduce your exposure to WiFi radiation.

10 Shocking facts about the Health Dangers of WiFi

  1. Contributes to the Development of Insomnia
  2. Damaging to childhood development
  3. Affects cell growth
  4. Derails brain function
  5. Reduces brain activity in females
  6. Neutralizes Sperm
  7. May Impact fertility
  8. Linked to cancer?
  9. Provokes cardiac stress
  10. You can protect yourself limiting exposure and staying healthy

Creating WiFi Monetization

  • Grow WiFi Network : Deploy public, hoe and business WiFi network
  • Baseline : Create compelling ROI through baseline business models
  • New Revenues : Deliver new sources of revenue and expand value of the WiFi network
  • Value Added Services : Enhance the WiFi network with new sources of value




Employee Use of Public WiFi networks

Percent of organizations with employees who connect company owned devices to public WiFi when on the go

  1. Yes –> 61%
  2. No –> 24%
  3. Don’t know –> 15%

Risk to Pregnant Women

There are radiation related risks throughout pregnancy which are related to the stage of pregnancy and absorbed dose and also radiation risks are most significant during organogenesis and in the early fetal period somewhat less in the 2nd trimester and least in the third trimester.

A pregnant woman and the fetus both are vulnerable a RF radiations pass placental barrier and continuously react with the developing embryo and increasing cells. Use of WiFi during pregnancy can lead to greater likelihood for behavioral problems in their children. It is believed that the eggs, which form the embryo can be affected and the damage will become apparent after the child reaches puberty.
