Let’s Create Our Own Cryptocurrency | cranklin.com
This implementation will not include smart contracts, transaction rewards, nor utilize Merkel trees. Its only purpose is to act as a decentralized ledger. It is rudimentary, but I will eventually fork a few experimental blockchains with advanced features from this one.

Ethereum Co-Founder Says Cryptocurrencies Are 'a Ticking Time Bomb' - Slashdot
Ethereum, the rival to bitcoin, has been on a tear. Its founders said the latest trend in the cryptocurrency space may not be as good for the cryptocurrency as some might think. Ethereum is up 1,700% over the last year, and that spike has occurred in tandem with the growth of the hottest new trend in fundraising: initial coin offerings. Approximately $1.2 billion has been raised by the new cryptocurrency-based capital raising method this year, according to Autonomous Next, a financial technology analytics service. It is a trend that has sparked excitement across Wall Street. But the cofounder of the company behind the cryptocurrency, Charles Hoskinson, told Bloomberg that initial coin offerings may not benefit Ethereum.
"People say ICOs are great for ethereum because, look at the price, but it's a ticking time-bomb," said Hoskinson. "There's an over-tokenization of things as companies are issuing tokens when the same tasks can be achieved with existing blockchains. People are blinded by fast and easy money."

Landregister (nötig wg KREDIT!)
It is virtually impossible to collateralize property rights in Ghana because the paper registry system is unenforceable in court. Because of unenforceability, banks won’t accept land as collateral. This situation leaves millions without the possibility of leveraging their property to get loans and rely on the rule of law for protection – continuing the ongoing cycle of poverty for much of the population.
