The supplier of dApp-solutions Level K revealed the details of the vulnerability in the Ethereum network, which was reported on 9 November.

The developers talked about the attack called “vector for griefing”, which exploited the possibility of random calculations using the address to which Ethereum coins were sent.

The attack could be capitalized through the minting of GasToken tokens, tied to the cost of gas in the Ethereum network, due to random calculations when receiving ETH to your address, and the initiator of the transaction would have to pay for these actions. As a result, the exchanges that did not implement such precautions as gas limits were threatened.

At the same time, the vulnerability concerned not only Ethereum, but also ERC-20 and ERC-721 tokens. Thus, a potential attacker could not only deprive the “hot wallet” of some exchange of substantial funds by burning gas, but also enrich themselves.

At the moment, all trading platforms that have received notifications from Level K have implemented appropriate security measures.

Monoplasma Ethereum Scaling Technology Unveiled

The developers of the blockchain platform Streamr presented a solution for scaling the Ethereum network called Monoplasma. It is reported by CoinDesk.

The creators of the project claim that the technology will help solve the problem of repeat payments from one address to many others. Monoplasma, in their opinion, will be useful to developers of decentralized applications focused on the distribution of dividends, staking and repeated airdrops.

The head of Streamr, Henry Pinkala, also demonstrated fake token airdrop for 200 thousand Ethereum addresses in a test network using Monoplasma.

You can receive money, but you can’t send back the other way. That would be like trying to send a message to your TV.

Thus, Monoplasma payment channels are reliably protected from the attack of double waste.

Streamr intends to use a new solution for the mass sale of user data on the blockchain, allowing the buying company to settle accounts with many users at once.
