Inflation Bug Still a Danger to More Than Half of All Bitcoin Full Nodes

Figures published by bitcoin core developer Luke Dashjr show that more than half of the full nodes in the bitcoin network are still running client software vulnerable to the inflation bug discovered in September 2018. This revelation poses some danger to the network, as software vulnerabilities are a clear and present danger to the fidelity of bitcoin (BTC). Now that the top-ranked cryptocurrency is in the midst of a positive price run, it is perhaps important that steps are taken to eradicate the inflation bug problem for good. Most bitcoin…

Just 2/3 of ETH Nodes Running Parity Have Been Patched Against Critical Security Flaw

Global hacking research collective SRLabs claims that only two thirds of the Ethereum client software that runs on Ethereum nodes has been patched against a critical security flaw discovered earlier this year. The news was reported by business tech website ZDNet on May 17. An SRLabs report ostensibly shared with ZDNet has reportedly revealed that the critical flaw is a denial of service (DoS) vulnerability in the Ethereum Parity client. As SRLabs has outlined, the flaw could enable a hacker to remotely crash legitimate Parity Ethereum nodes by sending malformed…

Ethereum 2.0’s Nodes Need to Talk – A Solution Is ‘Hobbits’

Developers working to create the next iteration of the ethereum blockchain have developed code intended to help client developers boost their testing efforts ahead of the upgrade. Ethereum 2.0 is by far the biggest upgrade on the agenda of developers said to bring massive improvements to scalability and usability on the now four-year-old blockchain network, which with its $17 billion market capitalization is the world’s second-most valuable blockchain. The work on the 2.0 iteration (also known as Serenity) continues apace, and according to Fredik Harryson, chief technology officer for client…

Parity Technologies Fixes Node Vulnerability, Urges All Ethereum Nodes to Update

Ethereum blockchain infrastructure developer Parity Technologies experienced a security compromise that required nodes to perform an urgent update, the company stated in a blog post on Feb. 3. Parity, which is a popular technology stack for Ethereum users, said it had received notification of a loophole which would allow an attacker to shut down nodes running its client. “On February 3rd, we received several reports that an attacker can send a specially-crafted RPC request to a public Parity Ethereum node (any version pre 2.2.9-stable and pre 2.3.2-beta) and that node…

Syncing Bitcoin Nodes Instantly with Zero-Knowledge SNARKs

A new Bitcoin scaling solution, which leverages succinct blockchains and zero-knowledge cryptography, has been proposed by a developer earlier this month.   The scaling proposal incorporates aspects developed and implemented in cryptocurrency projects Coda as well as zk-proofs, resulting in an implementation which supports an innovative type of Bitcoin client. The clients, which run this implementation, will be able to theoretically sync and validate the entirety of the chain in real time and with constant data size, regardless of the number of transactions, with full-validation security at nearly instant speeds.…

Progress Report: Lightning Network Surpasses $1M BTC Capacity, 4,000 Nodes

The Lightning Network continues to post steady growth. According to data from 1ML, the network is now supported by roughly 4,070 nodes, which house just over 12,500 payment channels, an average of 10.91 channels per node (at time of publication). Most of this growth has come in the later half of 2018, as the average age of each node is just 137 days old. With infrastructural growth, the network is also seeing an uptick in liquidity. At the time of writing, the network’s collective capacity now stands at 223.65 BTC, which, at…

EOS Developer Acknowledges Claims of ‘Collusion’ and ‘Mutual Voting’ Between Nodes

Block.one, the developer of blockchain protocol EOS, has published a statement on EOS public blockchain governance in an official Medium post October 1, signed by Block.one’s CEO, Brendan Blumer. In the statement, Blumer states that the company is “aware of some unverified claims regarding irregular block producer voting, and the subsequent denials of those claims.” Without providing any details on the “denials” of allegations, Blumer stated that EOS will continue to “ensure a free and democratic election process and […] vote with other holders to reinforce the integrity of this…

IBM Applies for Blockchain Patent to Ensure Transaction Compliance via Nodes Data

Tech giant IBM has applied for a blockchain patent for the development of transaction data identifiers based on nodes, according to a patent document published by the U.S. Patent and Trademarks Office (USPTO) Aug. 16. The system described in the patent, entitled “Node Characterization in Blockchain,” intends to introduce a method of data extraction from nodes on a blockchain network in order to identify different types of transactions. Specifically, any operation on blockchain may possess a node or a number of nodes that can carry useful information about the character…
