Ethereum Tests 25% Capacity Increase as Network Fees Hit Bitcoin Level

The move follows considerable upticks in Ethereum network usage, largely due to stablecoin Tether (USDT), which has shifted its reliance from Bitcoin via the Omni Layer to the Ethereum blockchain.

Ethereum network participants are attempting to raise the network’s block size as a direct response to network congestion.

Gas limit on course to become 10 million per block

As various parties including co-founder Vitalik Buterin confirmed this week, testing is currently underway to improve network performance and reduce transaction fees.

“Given the current #Ethereum network congestion we have started to test raising the block gas limit to 10M gas”, mining pool Bitfly tweeted on Sept. 14.

According to research data from monitoring resource Coin Metrics, as of Sept. 15, Ethereum users paid almost as much in daily transaction fees as Bitcoin users: $182,899 versus $185,993, respectively.

Since Sept. 1, the average Ethereum transaction fee has increased from just over $0.11 to just under $0.39, data from Bitinfocharts shows.

Ether benefits before Bitcoin break

Gas is the token, which Ethereum users pay for performing any operation on the network. A shift to 10 million gas per block is considerable, and would translate to a total capacity increase of 25%.

News of the changes appeared to buoy market of Ethereum’s native token, Ether (ETH), which earlier this week put in solid gains as other cryptocurrencies tracked sideways.

A sudden dip in Bitcoin subsequently sent altcoin markets lower, ETH/USD still holding onto support above $200 at press time.

Ethereum Network Overcame Intentional Attack Affecting Parity Nodes

The Ethereum (ETH) network was apparently the target of a coordinated attack, according to several analysts.

Following reports that some Parity Ethereum nodes lost sync with the network, on Dec. 31, core blockchain infrastructure company Parity Technology said it believed there was an attack underway and subsequently released network upgrades to protect against it.

According to cryptocurrency security consultant Sergio Demian Lerner, the attack was implemented in a simple way, wherein “you send to a Parity node a block with invalid transactions, but valid header (borrowed from another block). The node will mark the block header as invalid and ban this block header forever but the header is still valid.”

Software developer Liam Aharon analyzed the attack, concluding that it was close to taking down the entire network and that Ethereum could become much more vulnerable to similar attacks in the upcoming year.

Per Aharon, the attack did not manage to bring down the entire network because it has a client dubbed Geth, which is immune to the attack. However, taking into account Parity’s intention to transition Parity Ethereum to a DAO ownership and maintainer model, Geth could become the only well-maintained client in 2020, he said.

“If this scenario came true, attacks similar to today’s would devastate the network, instead of just being inconvenient,’ Aharon further wrote.

Efforts to fix vulnerabilities in the Ethereum network

During the past year, Parity has released multiple updates geared to fixing node vulnerability. In March, Parity CEO Jutta Steiner said that the new controversial Create2 Ethereum function would have prevented the Parity multisig freeze, following an incident when a user “accidentally killed” the Parity multisig library by activating a vulnerability to become the owner of the library, and then self-destructing it.

In May, global hacking research collective SRLabs claimed that only two-thirds of the Ethereum client software that ran on Ethereum nodes had been patched against a critical security flaw discovered earlier this year. The data reportedly indicated that unpatched Parity nodes comprised 15% of all scanned nodes – implying that 15% of all Ethereum nodes were vulnerable to a potential 51% attack.

Other recent attacks

On Dec. 29, holders of IOTA were unable to confirm transactions for 24 hours due to a mainnet incident caused by an unusual set of transactions that may have been constructed as an attack. The Iota Foundation emphasized that the incident had not been caused by software changes or any other components of the network, but rather occurred due to the “absence of transaction processing logic for an unusual set of transactions.”

Earlier this month, major cryptocurrency payment service provider BitPay confirmed that its service had a temporary outage of Bitcoin payments.
