Bitcoin engineers have rediscovered a major blockchain vulnerability found in 2018 on Bitcoin Core, the software that powers the Bitcoin blockchain, on the Decred blockchain, which is based on BTC’s code.

The total value locked on decentralized exchange Uniswap surpassed that locked on its rival SushiSwap after SUSHI block rewards for liquidity providers dropped from 1,000 tokens to 100. The total value locked on SushiSwap fell from $1.46 billion to $8855 million in a day.

The Bitcoin Association of Hong Kong, a major local alliance promoting cryptocurrency awareness and education, is launching an ad campaign dubbed “Bitcoin Tram” in the region.

Bitcoin Engineers Rediscover Major Blockchain Vulnerability on Decred

Bitcoin engineers have rediscovered a major blockchain vulnerability found in 2018 on Bitcoin Core, the software that powers the Bitcoin blockchain, on the Decred blockchain, which is based on BTC’s code.

The vulnerability was first found by Bitcoin protocol engineer Bradon Fuller. Called INVDoS, short for inventory out-of-memory denial-of-service attack,  it could see an attacker create malformed Bitcoin transactions that, when processed by nodes, would lead to an uncontrolled consumption of the server’s memory resources, leading to an eventual crash of affected nodes.

In a paper Fuller published, he wrote:

"At the time of the discovery, this represented more than 50% of publicly-advertised Bitcoin nodes with inbound traffic, and likely a majority of miners and exchanges."

In 2018 the vulnerability was quietly patched and kept a secret, to avoid hackers exploiting it on other blockchains build using the original Bitcoin protocol, such as Litecoin and Namecoin. At the time, the generic identifier CVE-2018-17145 so it would not tip off attackers.

The bug was now rediscovered by Javed Khan, another bitcoin protocol engineer, as he was hunting for bugs on the Decred blockchain.  Fuller and Khan noted that as far as they know, the vulnerability was not exploited.

Uniswap Surpasses SushiSwap Shortly After SUSHI Rewards Drop

The total value locked on decentralized exchange Uniswap surpassed that locked on its rival SushiSwap after SUSHI block rewards for liquidity providers dropped from 1,000 tokens to 100. The total value locked on SushiSwap fell from $1.46 billion to $8855 million in a day.

The total value locked on Uniswap, meanwhile, increased to $955 million. SushiSwap’s SUSHI rewards dropped as it executed a planned cut in block rewards for liquidity providers, following the successful migration of $800 million in assets from Uniswap.

The initial block rewards were designed to convince Uniswap liquidity providers to move to SushiSwap. The drop in total value locked suggests a significant number of liquidity providers were primarily motivated by the SUSHI rewards.

Hong Kong BTC Association Launches ‘Bitcoin Tram’ Ad Camapaign

The Bitcoin Association of Hong Kong, a major local alliance promoting cryptocurrency awareness and education, is launching an ad campaign dubbed “Bitcoin Tram” in the region.

The ad campaign composes three double-decker trams fully covered with Bitcoin ads, alongside 20 similarly-designed billboards across the city. Per Hong Kong’s Bitcoin Association, the ad campaign was initiated by the Hong Kong Bitcoin community and is coordinated by the association. It’s financed with donations from the community.

The Bitcoin Tram campaign is set to run until October 8, with billboards being set up on October 1. The announcement reads:

“We hope the campaign will give us the opportunity to discuss how Bitcoin fits into a quickly digitizing global economy, the opportunities and dangers of drastic technological advancements and the implications of digital, verifiable scarcity.”

Alongside Bitcoin logos, the campaign will include statements and quotes promoting BTC usage.

HYN, WAVES, BTM Are Moving the Crypto Market

There are several tokens leading the charge in the last 24-hour period. Some of these are well-known cryptocurrencies with rather liquid trading pairs, so we’ll be focusing on these over low-cap cryptos who may have higher percentage changes.

Hyperion (HYN) – Hyperion, a decentralized blockchain mapping platform that aims to achieve the “One Map” vision, in which it provides a unified view of global map data and service that is universally accessible, is up 31.09% in the last 24 hours.

Bytom (BTM) – Bytom, an open-source blockchain value-exchange protocol has reportedly been added to Amazon Web Services’ (AWS) Marketplace, meaning new developers who want to develop applications can deploy its mainchain or sidechain (Vapor) through AWS. The announcement saw BTM jump 7.8% in 24 hours.

Waves (WAVES) – Waves, an open platform for Web 3.0 applications and decentralized solutions, hs seen its WAVES token jump 8.45% in the last 24 hours. The jump is seemingly related to an announcement on an upcoming yield farming project along with several other partnerships.
