running a light Ethereum node on your Raspberry PI

As Ethereum ecosystem grows supporting the Ethereum network by running a full node has never been so important. The Raspberry pi is a pretty good option to do so:

  • There are lots of Raspberry Pis out there
  • The support by the community is Huge
  • Low cost and low power consumption

Note that the current raspberry pi 3 is not able to run a full node: Processing power, i/o bandwidth, and network bandwidth, mostly make it impossible to run a full node. Maybe this may have change with the raspberry pi 4 – 4 GB?

Last weekend I took part in the biggest Swiss Blockchain Hackathon #SBHACK19, and our team won twice!

  • BlockByte won in agriculture vertical.
  • BlockByte won First prize among 39 teams together with Velove team.

200+ hackers, 20+ countries, 39 teams, 7 verticals (Agriculture & Food, eGovernment, Mobility, Finance, Intelligent Parcel, Supply Chain) , 57 coaches, 6211 messages in Slack, 20 million lines of code written in just 42 hours!

Many interesting solutions have been developed in the fields of intelligent parcels, finance, agriculture and food and others.

BlockByte designed an immutable Land Lease Ledger (LLL based on R3 Corda) where the involved parties can enter agreements which are fed by historic land usage data, trusted events and benefit from a data-driven revenue and risk sharing mechanisms. A weather based parametric micro insurance using Ethereum was also added

IEO is currently the most popular fundraising trend in the crypto industry. As the name suggests, Initial Exchange Offering is conducted over the crypto trading platform and exchanges. So unlike ICOs wherein crypto projects directly approach investors, IEOs involve a third-party in the form of crypto exchanges.

An IEO is basically an ICO except that it is launched and managed by an existing exchange instead of the organization that created the token. The exchange holds and sells the token on behalf of the project team.

A new group of investors is therefore forced to register and use the exchange platform.

Many of the top exchanges who are Launch Initial Exchange offering ( IEOs) have different requirements that involve holding or using their own platform tokens in order to participate in the IEO. By creating this condition, exchanges create demand for their internal tokens, which increases its value.

The project team needs to meet and comply with the exchange’s platform requirements (due diligence) to initiate token sales

The first crypto exchange was the Binance exchange launching its “Launchpad” platform.

Security token offering (STO) is a type of fundraising that is performed with a company offering tokenized securities. The defining feature of security token offerings is in its definition. Stocks, bonds and managed property trusts are another examples of securities.

Essentially, a security token is a cryptocurrency-based asset that derives its value from some other asset that it represents. For example, security tokens can represent real estate or gold but, most importantly, they can represent shares and securities or their alternative.

The tokens offered during an ICO are called utility tokens, their value is based on demand for the product or service which requires the tokens. They are not normally legally-binding contracts and do not represent any underlying assets.

This FREE book is focused on those people designing and develop‐ ing blockchain networks, the early chapters have a broader scope.

Oreilly – Getting Started with Enterprise Blockchain A Guide to Design and Development

This book introduces you to the value that blockchain brings to the enterprise. We focus on private permissioned blockchains, which we describe in Chapter 1, and why they are suitable for use in an enter‐ prise environment. While we make comparisons to public unper‐ missioned networks in Chapter 1, we don’t discuss public networks beyond this. This book looks at how to choose the best scenario for blockchain, and at considerations for designing a blockchain net‐ work, before finally looking at how to develop your blockchain application. Throughout this book we focus on a real-world scenario for com‐ mercial papers with Chapter 5 introducing a developer tutorial and how to run and extend a commercial paper network on blockchain.

After updating my Page about the Biggest Crypto Loss, Hacks, Scam of All Time, i came down to a new record number of Bitcoin that maybe lost forever. As the subject is sensible, this need some more explanations how I came to that crazy number

BTC Confidence Explanations
A further million coins are said to be lost, due to them being the original Bitcoins that pseudonymous Bitcoin creator Satoshi Nakamoto mined before disappearing. Although it’s always possible that he will re-emerge and claim his fortune, it seems more likely at this stage that his fortune will remain untouched.
4m80%Chainalysis, a cryptocurrency and blockchain analytics company, first revealed in an interview with Fortune that between 2.78 and 3.79 million BTC are already lost on the bitcoin blockchain. That number was released in November 2017.
Chainalysis’s conclusions rely on segmenting the existing bitcoin supply based on age and transaction activity. For some segments, the company used statistical sampling to determine the amount lost.

7500100%JAMES HOWELLS LOST 7,500 BTC IN 2009
“I (James Howells, a 32-year-old IT specialist) mined more than 7,500 coins over one week’s time in 2009; there were just six of us doing it at the time, and it was like the early days of a gold rush. Four years later, I had two hard drives in a desk drawer. One was empty, and the other contained my bitcoin private keys. I meant to throw away the empty drive — and I accidentally threw away the one with the bitcoin information,” said Howells.
“I looked up the price, did the calculation . . . and thought, ‘S – – t. [My investment is] worth around $2 [million] or $3 million.’ A few months later it was worth $9.9 million. I was annoyed, pissed off, sick. I spoke to the people at the landfill and told them that I threw away a hard drive worth $10 million. They looked at me stupidly.”

  1. If you are considering an Initial Coin Offering, sometimes referred to as an “ICO,” or otherwise engaging in the offer, sale, or distribution of a digital asset,

2. you need to consider whether the U.S. federal securities laws apply. A threshold issue is whether the digital asset is a “security” under those laws.

3 The term “security” includes an “investment contract,” as well as other instruments such as stocks, bonds, and transferable shares. A digital asset should be analyzed to determine whether it has the characteristics of any product that meets the definition of “security” under the federal securities laws. In this guidance, we provide a framework for analyzing whether a digital asset has the characteristics of one particular type of security – an “investment contract.”

4 Both the Commission and the federal courts frequently use the “investment contract” analysis to determine whether unique or novel instruments or arrangements, such as digital assets, are securities subject to the federal securities laws.
