Without a doubt, Stellar has one of the strongest communities around its token in the crypto space. They encourage people to use their product and build useful tools with it. Let’s take a look at how they do it.

This article will guide ICO members through the elements that make up a secure ICO project. It’s also intended for investors as a form of checklist to verify how secure a project actually is. Any project should at least consider the elements listed in this article.

Location-based advertising is the new way of advertising and can be expected to account for a growing proportion of marketing spending. The increasing number of connected devices lowers the entry barrier and makes the collection of location data easier. It’s therefore not unusual that more and more location-based data startups pop-up. Here’s an overview of blockchain-based location data startups, presented in a question-and-answer format.

On the 3rd of June, ZenCash suffered from a 51% attack where more than $500,000 in double spend transactions was lost. The attacker managed to manipulate blocks which allowed him to double spend on two massive transactions of respectively 13,000 and 6,600 ZEN. According to estimates via the website 51Crypto.app, the attacker only had to spend $30,000 to pull off the 51% attack.

The Cosmos Blockchain is a novel answer to “sidechains,” which aims to enable users to traverse a galaxy of blockchains with ease. Cosmos wants to offer multiple parallel blockchains to interoperate while retaining their security properties.

Steemit is by far the most successful blockchain based social network. The Steemit economy depends on three currencies: steem (STEEM), steem dollars (SBD), and steem power. Steemit is one of the few properly working crypto projects that have seen a huge adoption rate, even from outside the crypto space.

Enigma is an off-chain, peer-to-peer network that provides various parties with the ability to jointly store and perform computations on data while keeping it completely private via the use of secret contracts. Guy Zyskind, CEO and co-founder of Enigma, helped us produce an overview of secret contracts and how they work.

Next to the well-known ERC20 standard, other standards exist which try to improve the original standard. ERC223 is focused on security seeking to solve an ERC20 critical bug which has caused the loss of millions of dollars. ERC777 focuses on a wider set of transaction event handling functions and mass adoption

DIDs represent an important innovation because they give us the ability to establish digital identifiers that are persistent, secure, and globally resolvable, yet their creation does not require a central authority or intermediary.

Hashgraph is a blockchain-alternative that achieves high scalability without sacrificing security. It has been proven to handle hundreds of thousands of tx/s in a single network and is expected to do millions of tx/s with sharding. Hashgraph makes use of “Asynchronous Byzantine Fault Tolerance (BFT)”. A very secure version of BFT.

Atomic swaps, or atomic cross-chain trading, is a decentralized cryptocurrency-to-cryptocurrency trading method that relies on smart contracts, without having to trust any intermediary, or third party. The Komodo project is currently the most prominent project in the "atomic swaps" arena, yet it is still under development.

Too many concepts are translated into blockchain projects. We present several blockchain decision models and paths to guide you on deciding whether to use blockchain or not. In short, a blockchain is useful when transparency in needed, and to prevent fraud among trust-less parties.

A Tangle is a novel technology concept that can mitigate most of the problems associated with blockchain based cryptocurrencies. Cryptocurrencies relying on a "Tangle" have no transaction fees, miners or blocks. Examples of Tangle based cryptocurrencies include IOTA and Byteball. With Byteball you can make safe contracts that will be executed exactly as agreed upon. IOTA is ideal for micropayments and "machine-to-machine" payments.
