The leading manufacturer of mining equipment Bitmain announced the start of sales of new Antminers - S15 and T15, equipped with 7-nm chips.

According to the information on the company's website, the cost of the devices is $ 1,475 for the Antminer S15 and for the Antminer T15. The tentative start of deliveries is between December 20 and 31, 2018.

For large mining farms, both modes are easy to implement as an all-in-one design of miner with PSU and can be set up vertically or horizontally, making it flexibly adapted to different mining farms and miner racks. With the new high conversion power supply APW8, 16-18V high-voltage output, new miners can effectively reduce the power loss during the power conversion process, helping mining farms save on electricity costs.

The creator of Ethereum, Vitalik Buterin, published on GitHub a proposal on changing the reward scheme for validators after the transition of ETH to the Proof-of-Stake consensus mechanism (PoS).

According to the formula proposed by Buterin, if PoS-validators, for example, validate 1,000,000 ETH, then the annual yield will be 18.1%.

The more assets are fixed for validation, the lower the interest rate. So, 134 217 728 ETH will bring cryptoinvestors only 1.56% per annum. At the same time, the maximum annual emission volume will be 2,097,152 ETH.

Considering that the current volume of Ethereum's market offer is 105,777,585 ETH, this offer is focused on the medium and long term. Buterin also clarified that the profitability indicators are shown without taking into account proceeds from transaction fees. Consequently, the actual income of validators can be several percent higher than the values ​​indicated in the table.

According to Justin Drake, a researcher at the Ethereum Foundation, if after implementing PoS 32 million ETH will be allocated for stacking, the income of validators will be 3.2% per annum. At the same time, the annual emission indicator will be 1% (for comparison, the current indicator of Bitcoin inflation is 3.94%).

In this case, Drake notes that after the activation of EIP 1559 of the funds collected in the form of commissions, will be destroyed. Consequently, with an average gas consumption of each shard of 1000 ETH per year, inflation will drop to 0.5%.

Users left generally positive comments on the offer. However, some of them expressed fears that in the new conditions the exchange may receive significant advantages, which will be able to do stacking at the expense of clients.
