Major Cardano Milestone: How Shelley Improves Stability and Decentralization
April 17, 2019 10:18 AM -Bitcoin news, price, information & analysis Yesterday, CEO of Cardano, Charles Hoskinson announced the completion of a significant roadmap goal. The Shelley phase relates to stability, interoperability, and governance. But more than that, the primary objective behind it is the decentralization of the Cardano network via staking. The soul of Shelley is out https://t.co/5Hcwt40BsU ? Charles Hoskinson (@IOHK_Charles) April 17, 2019 Under Shelley, Cardano will provide incentives to those who actively participate in the Proof of Stake consensus protocol. However, what makes Cardano different, is that Cardano acknowledges that not everyone wants to run an active node 24/7. For that reason, ADA holders have the option to delegate their stake to a staking pool.

Privacy aware IOTA ledger: Decentralized mixing and unlinkable IOTA transactions
April 17, 2019 8:37 AM IOTA is a distributed ledger technology for the Internet-of-Things (IoT) industry. The protocol distinguishes itself from existing distributed ledgers by being formed on a directed acyclic graph. To enable micro-transactions for smart devices, it uses a scalable approach for network growth and transaction confirmations. Being a public distributed ledger, the transactions on the ledger are completely transparent hence opening up the possibilities for linking and identification attacks. Different promising privacy enhancing techniques have been proposed for improving anonymity in distributed ledgers. However, many of the proposed approaches provide security guarantees only against Elliptic Curve Digital Signature (ECDSA) schemes and thus become incompatible with the IOTA ledger because IOTA uses quantum resilient hash-based signatures. While centralized solutions can still work with IOTA ledger for enhancing privacy, they are still proprietary and prone to single point of failures. We propose a novel decentralized mixing protocol for the IOTA ledger that incorporates a combination of decryption mixnets and multi-signatures. Our technique does not require any (trusted or accountable) third party and it is completely compatible with the IOTA protocol. Analysis of our results for this technique shows that the security and privacy are guaranteed even in the presence of malicious entities in the system. Our technique provides strong privacy to the IOTA ledger and the degree of anonymity it adds, protects entities against identification and linking attacks.

Decentralized Developer Reward: Completing The Incentive-Circle
April 03, 2019 11:51 PM Cryptocurrency development is difficult. It requires a high degree of technical competence and 24/7 readiness in order to respond to any issue. Mining cryptocurrency is expensive. It requires big investments and constant maintenance. Both development and mining consume time, labour and material and both are necessary to maintain the cryptocurrency ecosystem. When Satoshi launched Bitcoin, he added a mechanism to reward miners for their contribution. However, no such reward was added for developers. It was assumed development would be contributed for free on an altruistic basis. Since no cryptocurrency can yet support a global adoption scenario, it?s clear that development is still required in order to achieve the global adoption vision. Also, due to constant innovations in cryptography, it?s clear that development will be required after the global adoption vision is achieved, if at all. It stands to reason that a successful cryptocurrency will require constant development. But how is this development to be funded, if only the miners are receiving a reward? Well, there?s a few options:

Decentralized exchanges vs classics: for whom victory
April 01, 2019 6:32 PM Decentralized exchanges vs classics: for whom victory With the advent of the blockchain, the word "decentralization" broke into the lives of most modern people. Over time, it has become a kind of synonym for technology. However, despite the availability of decentralized systems for working with digital assets, centralized sites still occupy leading positions. About the differences of approaches, myths and features of choice, - further in the material. Myths about decentralized sites Decentralization implies the one-time storage of a large amount of information in the computers of network participants. The advantage of the approach is the following: when accessing data from one computer, an attacker will not be able to damage the network, since the copies of the data are stored on the devices of other users. The immutability of the blockchain information is guaranteed by linking the blocks to each other (up to the first block - the genesis). Accordingly, in order to replace one part, the fraudster will have to completely rewrite the chain, replacing it in the computers of all the participants of the system. At the same time the set of actions will require a huge amount of computing power, which is unlikely to be able to organize. In fact, work on the blockchain is indeed a new approach to security organization. However, for the effective operation of the system, a mass of auxiliary tools are needed, which must interact with the technology. In addition, the organization of secure data storage is not the only need of modern users. Details of productive work are also: - system performance; - stability of the technical component; - operational fixation of operations and so on. The above details can?t be fully provided with the blockchain. However, other difficulties associated with the lack of plasticity of decentralized solutions become brighter. Accordingly, the blockchain can?t be considered as a "magic wand" that can solve all the problems of modern exchanges. Propaganda Features The centralized exchanges continue to use effective, time-tested technical solutions. At the same time, the level of their security remains one of the most discussed topics in the crypto community. Representatives of the decentralized sites are extremely profitable to create propaganda of their chosen path, attracting users by staging the blockchain as the basis of security. At the same time, there are problems in the area of speed and the fact that the centralized services are more efficient in their work. It is also important to pay attention to the safety of work at the centralized sites. The lack of implementation of distributed information storage solutions is not a problem, despite the attempts of representatives of decentralization to put this fact in the darkest colors. In fact, the creation of conditions as close as possible to the security indicators of the decentralized exchanges is quite a real task. In the arsenal of the centralized sites there are a lot of tools through which user information can receive an adequate protection. Solution for the modern user The ideas underlying the decentralized sites seem to be extremely interesting, since blockchain can really bring to the world of working with the digital assets the opportunity to look at security from a different angle. However, the presence of a number of drawbacks and the low level of plasticity of such exchanges don?t allow them to be considered as the main choice for performing operations. The centralized sites, in turn, provide the effective technical solutions for fast and safe operation. Since working with digital assets depends largely on the speed of the system, the choice in their favor remains optimal. Probably in the distant future, when the decentralized exchanges will no longer be so clumsy, they will be able to gain real popularity. However, until the changes have occurred, working with them doesn?t allow achieving the benefits that meet the requirements of the ordinary user. Amanpuri offer The Amanpuri platform team offers its users the benefits of two worlds: the security of decentralized sites and the speed of their centralized counterparts. The result was achieved due to the plasticity of the technical solutions of the site: the combination of the best components of the two views allows us to solve the eternal problem of the modern user?s choosing. Amanpuri challenges the current leaders in the digital asset exchange markets. The set of technical solutions of the site allows you to compete with the most famous representatives of the industry, offering users the best working conditions. The main feature of Amanpuri is to identify the shortcomings of the other exchanges, with their subsequent processing and transformation into their own dignity. Summing up It turns out that the value of the decentralized sites, in their current state, is exaggerated. The centralized exchanges, in turn, are capable of combining the advantages of both worlds, forming the necessary user support. A vivid example of combining the best qualities of modern sites with a decent level of security is the Amanpuri project. With its launch, the users of cryptocurrency will receive long-awaited support, due to which the world of digital assets will continue its development. Our information links.

Binance Launches Testnet for Decentralized Exchange, Elon Musk Says Bitcoin has a Brilliant Structure
February 21, 2019 5:39 PM The recent bull run in the crypto markets has subsided as markets traded sideways during the day. Bitcoin, which broke the $4,000 after an impressive 2-day rally, has retreated to $3,978, 0.17 percent down in the last 24 hours. However, Bitcoin is still up by more than 8 percent since the beginning of the week. Bitcoin did not go down alone. It was followed by Ether and XRP who are 0.30 percent and 1.80 percent down respectively. EOS and Litecoin are both up 5 percent in the same period and Bitcoin Cash posted a gain of 0.25 percent. Despite the losses and gains, the overall market cap remained relatively stable at over $134 billion in the last 24 hours. On a positive note, the total trading volume reached $33.85 billion, its highest figure in 10 months. The uptick in trading is an indication that investor interest is back and the surge is not just a temporary increase in prices. The entire market has increased by approximately 12 percent in the last seven days. The top 10 digital assets accounted for about 88 percent of the trading volume registered on Feb. 19. Bitcoin, the largest digital asset and the stablecoin Tether recorded trading volumes or more than $9 billion.

Lightning Network's stunning growth has been fueled by Plug & Play Nodes
February 18, 2019 4:30 PM Expansion of the bitcoin microtransaction network, Lightning Network (LN) is a reality. Just over a year after its official launch, this second layer solution for Bitcoin?s scalability is becoming more and more established. Proof of this is the increase in nodes and pay channels of the network, as well as the routing capacity in BTC. An extremely significant aspect is the increase of the network nodes. According to 1ML, currently the network has a total of 6,335 public nodes, this figure includes active and deactivated nodes, a figure that has not stopped growing since its birth and has dramatically increased, coinciding with the new offer of plug & play nodes (connect and use), which make it much easier to operate a node than it has been until now.

Decentralized Apps Might Be the Future but They re Not the Present - Bitcoin News
February 13, 2019 12:39 PM To their proponents, dapps ? decentralized applications ? are the future of internet. To their critics, they?re multi-million dollar sinkholes, with huge development costs, poor UI, and no users. Are dapps like Augur and IDEX early test cases for the web to come, or impractical experiments that are destined to fail? Also read: Bitcoin ATMs Now In The Thousands Around the World Hating on dapps has become something of a parlor game. They?re an easy target after all. While all the headlines are about VCs pouring millions of dollars of seed money into dapps like Crypto Kitties, and the highly publicized launch of Augur (market cap $311 million), behind the scenes, things are less than rosy. The latter, which launched with great fanfare several years and personnel changes later, typically has less than 60 daily active users (DAUs) and yet Augur is supposedly ethereum?s flagship dapp.

Bitcoin is all about personal accountability: Did you know that one guy mistakenly paid 291 BTC in fees to send 0
February 10, 2019 9:59 PM Myths and legends entwine around the whereabouts of millions of to date lost Bitcoin. Unsurpassed, however, is the BTC fortune of Bitcoin creator Satoshi Nakamoto, presumably destroyed for all eternity. A short story about the curiosities of cryptography. Cryptography is all well and good. But what if you lose your private key due to carelessness? Bad luck. Unfortunately, it?s that simple. The SHA-256 hash function is a good thing for security in the Bitcoin network. It?s not for nothing that SHA stands for ?Secure Hash Algorithm?. And Nakamoto has really taken security seriously. Because both the Bitcoin Mining and the mathematical connection between Public Key and the address is based on SHA-256. And that is really bomb-proof. Key collisions are mathematically extremely unlikely.

Lightning Network is an ocean of possibilities: Unlock WiFi access with a LN payment
February 05, 2019 11:45 PM One user has implemented a proof of concept to gain access to a protected WiFi network, using Lightning Network. The instructions and code for this tool were published yesterday. A development team created Nodogsplash (NDS), a captive portal that offers a restricted Internet connection, which can be unlocked using certain parameters. A Spanish developer known as @poperbu has seen the potential of this application and developed a plugin that allows, for the payment of 100 satoshis (0.000001 BTC) through Lightning Network (LN), the WiFi network to be available. This developer published a video with the necessary steps to cancel the fee requested by NDS with LN, with the help of a Telegram bot. Similarly, this user indicated on Twitter that the portal will allow users a limited connection, enough to make payment with LN and enjoy the Internet service.

Building a decentralized Reddit - Part 1
February 04, 2019 6:52 PM In this tutorial we want to get very practical and build a decentralized Reddit application from scratch using Embark. The goal is to get a better idea of not only what parts and components are involved when building such an application, but also which steps are required to get there, without getting too overwhelmed. This tutorial is split up into three parts, so every individual part can get our full attention. The three parts are going to be: We will link the other two parts once we?ve published them. Alright, let?s start off with quickly talking about what exactly it is that we want to build. Obviously, Reddit is a pretty sophisticated platform so we won?t be able to rebuild it completely. Instead, we?ll be focusing on some key features that will also demonstrate very nicely how Embark can help building such an application.
