Diode’s CTO Dominic Letz published a paper recently to give an introduction of BlockQuick, a super light client protocol for blockchain validation on constrained devices. One of the key concepts behind the newly proposed BlockQuick is that it plans to adopt a consensus-based reputation scheme to accept blocks. This article explores how blockchain synchronization of Internet-of-Things (IoT) devices can be achieved through BlockQuick consensus reputation table, as...

Why The Internet Infrastructure Is Vulnerable To Bgp Hijacking Attacks

Security

Earlier this month, Doug Madory, Oracle’s director of internet analysis, wrote in a blog post detailing a BGP route leak incident happened on Thursday, June 6. For approximately two hours, a massive amount of European Internet traffic was rerouted through China Telecom’s own servers. The Internet traffic was rerouted following a BGP route leak at Swiss data center colocation company Safe Host. Over 70,000 routes - comprising an estimated 368 millions IP addresses coming...

Messaging Service Telegram Was Hit By a DDoS Attack, What Needs to Change?

Security

According to a report, Telegram’s CEO Pavel Durov confirmed on Wednesday (June 12) that his popular messaging service experienced a “powerful” Distributed Denial-of-Service (DDoS) attack. The DDoS attack disrupted Telegram’s services for about an hour. He later tweeted that the IP addresses involved in the attack were coming mostly from China.

How Blockquick Super Light Client Protocol Can Help Mitigate Eclipse Attacks

Blockchain

In May, Diode’s CTO Dominic Letz published a paper introducing BlockQuick, a super light client protocol for blockchain validation on constrained devices. The paper shows that unlike other existing approaches such as proofs of proof-of-work (PoPoW) and FlyClient, Diode’s BlockQuick super light client protocol is capable of protecting against eclipse attacks and man-in-the-middle attacks on a peer-to-peer network. But what is an eclipse attack? Is it possible to prevent...

How Decentralized Public Key Infrastructure Will Be The Future For The Web

DPKI

If you’ve been following our blog, you will have heard us mentioning the term decentralized public key infrastructure before. But you probably don’t know what it is or how it works, let alone why it matters so much. In this post, we will examine current approaches to the traditional centralized PKI, explore the basics of decentralized public key infrastructure (DPKI), and then show how blockchain-based DPKI can make an impact as the industry transitions...
