Ledger Nano S Hardware Wallet Review

Ledger Nano S Review

If you’ve considered a cryptocurrency hardware wallet, then you’ve probably already come across the Ledger Nano S. And for good reason! The Nano S is the result of success of the original Ledger Nano. A screen and pair of buttons helps the user enter information on the device directly. But perhaps the most sought-after aspect of the Ledger Nano S is its multiple token support and attractive price. It is only $69 USD (about 58 euros) to top competitor Trezor’s $117 USD (about 99 euros).

Multiple token support

Ledger app management softwareIn the beginning, hardware wallets were primarily designed solely for use with Bitcoin. Even as alternative cryptocurrencies such as Litecoin started popping up, no hardware wallets were made to support this. Part of the problem is differing cryptographic algorithms. Ledger decided to solve with this with Ledger Blue and Ledger Nano S devices, which support apps. That’s right, the app model is now prevalent on our security devices!

Blockchain & IoT: What does the future of cloud look like?

Is blockchain the right solution for IoT?

Following up from a talk at IoT Summit in Boston, Taylor Gerring gives an interview to Sravani Bhattacharjee about Blockchain and IoT. They discuss future of the cloud looks like and how we can scale to 20 billion devices with machine-to-machine payments.

Interested in learning more about how the blockchain could impact the internet of things? Then this interview is for you!

Blockchain and Identity Rights: GDPR and Passwordless Authentication

Blockchain and Identity Rights: GDPR and Passwordless Authentication

Taylor Gerring joins Ben Matthews (BCS Consulting), Greg Jendroszczyk (Piwik PRO), and George Wilson (Tallysticks) for a lively panel on how the blockchain will play into the future of digital identity & reputation.

In this panel, we tackle common questions such as:

  • How is Blockchain securing the Internet?
  • Biometrics vs password authentication
  • Should users have full control of their identity?
  • How can Blockchain help with KYC/AML challenges?

Hellooooooo internet!

Hellooooooo internet!

Welcome to Blockchain.WTF, where we aim to curate the best information about cryptocurrencies and the blockchain industry. While we’re not alone in this journey and a variety of other resources exist on these topics, we have an explicit goal of being approachable, practical, and relatable… and to do it all in a fun way! We hope these ingredients will add to the recipe of global blockchain adoption. Will you help us get there?


We’ve started this project as a way to reach out to a wider gamut of users that depend on technology in a more practical sense, i.e. “How does this help me?”. Over the last few years, the definition about what a blockchain is and is not has gone through many refinements. We firmly stand in an era where the banking industry’s attempts at coopting blockchain technology has resulted only in blockchain inspiration—not a blockchain itself.

The king is dead, long live the king!

What we’re left with is a clear definition of blockchains that does indeed encompass a set of technologies, but also represents an ideal bolstered by anti-fragile protocols that enforce a social compact to the benefit of its users. As we move into 2017 colored by Brexit, Trump, and far more worries than any individual could possible handle, we have to start asking ourselves what the solution is to the widening chasm between people and their governments. Instead of expecting the very broken system to produce some magical fix (a “silver bullet”), we can instead look to new sorts of governance that obsoletes the old. These new system will have to remain free of control of any particular entity and should be native to our new reality augmented by the internet. For this, blockchains (not “distributed ledger technology”) is an ideal candidate.

Beyond the blockchain bubble

Since I got you at least this far into the article, it’s probably time to shamelessly cross-promote my talk from Ethereum DEVCON2 on this exact topic. Don’t have time for a video? I got you—my TLDR is below

Too Long; Didn’t Read

What I’m trying to suggest in this presentation is a core idea of making blockchains appealing to general masses, not due to idealogical or philosophical alignment, but instead due to practical use cases that tangibly improve their lives. This means talking about some of the problems we currently experience and how magic internet technology on our mobile phones could make things so much easier.

Filling out a new patient paper form only to have it typed on a computer is silly—wouldn’t it be easier to text my contact card? Of course, things work a bit different in blockchain land, where you always retain control of the data and grant/revoke permissions as needed. While this example is a common frustration we share, such commonalities can be limiting. Instead of finding the “perfect elevator pitch”, we should find 100 of them and connect people to those ideas that resonate most strongly with their day-to-day needs.

Starting from Scratch

The long and short of it is that we now have the technological capability to build a system that Bucky Fuller would be proud of. One that obsoletes the old, broken, highly politicized and inaccurate Diebold voting machines and replaces it with a system of digital signatures and “own your own data”. When combined with innovations in privacy so that we can count votes without revealing who voted for whom, the future might not start to look so bleak. All we ask is you share this with loved one and help make it be the best resource when your friends ask “Where do I go to get started with blockchain?”

20 GOTO 10

What we’re trying to build with blockchain wtf is a brand that can reach a global audience and do it in an easy-to-understand, down-to-earth, relatable way. That’s why we’ve organized content around specific industries of concern. Know a nurse? Send them a link to the healthcare section and help them get a leg-up on what might impact their career. Know a technologist? They might love learning more about web3. In general, we want to share tangible and socially beneficial stories with all of our families, friends, and tribes. Taking blockchain and cryptocurrency from a nascent industry to global adoption will mean we do the dance of YouTube, Facebook, and all the rest. In the meantime, we’ll be framing everything in the context of what is wrong and what we’re actually doing to fix it. If all goes well, we’ll document the whole process and help teach others along the way. Will you join us on this adventure?
