Bitcoin Lightning Network: Why It Could Be Beneficial For Node Operators

Lightning network is a scaling solution implemented in the Bitcoin blockchain which allows a transaction to be offloaded from the main chain and take place on the off-chain. This would help reducing the congestion on Bitcoin’s main chain, respectively make transactions faster and cheaper. Lightning Network Principle Basically, Lightning Network is a channel which is created between two peers. It’s considered as different from the side chains, as they are simply blockchains on their own. The fewer the channels are, the more lightning networks need to be used in order to send a transaction. Each usage means there is a transaction fee which goes to node operators who maintain those channels. The number of active channels on the main net...

IOTA implements Local Snapshots

The IOTA network observed a significant increase in the activity, credit by developers, who are implementing solutions, based on the Tangle technology. Considered as a challenge by the IOTA Foundation, this enlargement of the database’s size and create some trouble to nodes, which possess limited hardware resources. As some global snapshots were taken on regular basis, it’s been decided that the growth of the ledger’s size isn’t that practical, because storing transaction’s history is forming an empty database. Next on the Roadmap – Local Snapshots In order to make some steps to solve the above-mentioned problem, IOTA announced they’re launching a new feature, called Local Snapshots. Currently, the new implementation has been tested internally and the metrics of its behavior...

Vitalik’s new consensus algorithm

The co-founder of the Ehtereum platform – Vitalik Buterin, published on his website a paper, which describes a new consensus algorithm supposed to achieve 99% of fault tolerance. Only 1% of the nodes in the network should be honest in order to work and provide the security bump, which is required. This reduces the current need of 50% of nodes to provide a trustful information. Ultimately, this diminish the risk of malicious attacks when the numbers fall to 49% and below. While 51% attacks are unlikely for the Ethereum network, or any other decentralized blockchain, if this new method for achieving consensus proves to be working, it can dramatically increase the blockchain’s security and bring the solution of the Byzantine...

“Node characterization in a blockchain” patent application from IBM

IBM continues its expansion into blockchain technology – a patent application filed by the tech giant was released couple of days ago by the U.S. Patent and Trademarks Office – USPTO, called “Node characterization in a blockchain”. The patent paper outlines different types of data extraction from blockchain nodes such as ‘entity extraction, text mining, information analysis and discovery, semantic extraction’, etc. The nodes on the blockchain can hold useful extracted information, which can give an insight about the nature of transactions. This type of data tracking could be used for various purposes from governments and lawmakers through regulators. The system is deployed with modules that can be implemented as hardware circuit or gate arrays, transistors or other components. The...

Ledger Nano S now supports Particl Cold Staking

Ledger officially implemented the Particl in their own Live application. Now you can create your Cold Staking Node with Nano S devices and use it as cold storage at the same time. This is the very first Proof of Stake coin which is able to stake on a hardware device without any connection to Internet or any other type of intermediary. If you already own a Ledger Nano S device or want to learn more, you can check how to setup your own cold staking node with this tutorial on the Particl wiki page. Improvement of security Hardware wallets such as Ledger Nano S are simply a perfect choice to store your cryptocurrencies. They are designed to protect your coins...

Zcoin Dandelion Integration

Zcoin is the first implementation of the Zerocoin protocol which uses Zero-Knowledge Proofs to assure a complete financial privacy and anonymity of the blockchain. As a privacy coin, Zcoin needs to protect your personal information such as the IP address, which can be linked to transactions and other addresses on the blockchain. This type of link ability is mitigated through the usage of TOR/I2P/VPN. It is important to note that Bitcoin and Zcoin transactions don’t contain any IP addresses. The only place, which is able to store that kind of personal information are the nodes in the P2P network. When the transaction is relayed from one node to another, there is no way to identify it as the original broadcast,...

ZenCash Super Nodes are here!

The beta testing period of the Zen’s mandatory upgrade started on the 10th of July. ZenCash Super Nodes were officially launched 9 days late. Their whitepaper was published months ago, introducing the unique node network. Previously, it was operating with Secure Nodes, which helped the decentralization and censorship process. This made them resistant and also allowed them to be rewarded. When speaking of Secure Nodes, you need at least 42 ZEN to stake, also possess a TLS certificate and enough computational power to process the challenges in the network. With the introduction of Super Nodes, ZenCash aims to raise the security and bring more utility with future services that will be implemented in the system. Super Nodes are more powerful...

3 Good VPS Hosting Providers for Cryptocurrency Nodes

If you want to support the network, or mine the coin you like, you will need a Full Node. Or maybe you want to have a Masternode or some other type of node which needs to run constantly without interruption. The best way to do this is to rent a VPS – Virtual Private Server from a hosting provider and create your node on it. There are plenty of hosting services out there, but we will focus on the most broadly used in the crypto space. Vultr.com The company has 15 datacenters close to major cities across the globe and was launched in 2014. They offer a wide range of configurations with several operating systems including Windows, ability to make snapshots...
