[PoW Round-Up] 90% of Bitcoin mined, network difficulty keeps climbing

Learn about industry news, development updates, community happenings, and other aspects of the PoW world!

Bitcoin and Ethereum are becoming more scarce as their supply issuance becomes more deflationary and they continue to witness network adoption.

Mining industry

  • Bitcoin

The mining revenue decreased to $0.25 per 1 TH/s, from $ 0.33 two weeks ago. This is due to the price action and high level of mining difficulty, causing fierce competition among miners. It’s been more than 4 months since the price per 1 TH/s has been at this level.

The Bitcoin network witnessed a significant difficulty increase of 8.33% on December 11, 2021. Despite a minor decline of 1.49% in the last two-week cycle, the trend remains positive and has been moving upwards since the end of July. It’s at nearly the same level of difficulty ATH as during the middle of May when it was 25.05 T.

  • Ethereum

Like Bitcoin, Ethereum mining is experiencing hashrate growth this month. Its highest average hashrate of 932,658.5 GH/s was recorded on December 14, 2021. With combined factors of the price dropping and hashrate climbing, the current unit revenue of Ethereum mining is around $0.064 per 1 MH/s — compared to $0.075 at the beginning of December.

The network just crossed 1.21 million ETH burned in 132 days since activation of EIP-1559, with a burn rate of 6.28 ETH/min, offsetting issuance by 0.62x. During the most recent 30 days, ETH transfers rank top on the burn leaderboard.

Dev and network

  • Ethereum

Arrow Glacier upgrade was successfully performed at block #13,773,000 on December 10, pushing back the difficulty bomb to June 2022.

The last ACD meeting of 2021, #128 was hosted following the upgrade. EIP-4488 proposed to reduce rollup transaction costs, at the cost of more chain history growth. This proposal was discussed but will not be conducted before The Merge, with devs deciding to stick with the current plan and prioritize the transition to PoS. A full recap can be found in this thread.

Vitalik Buterin released his post Endgame, walking the readers through two main ways of scaling possibilities, and what it means to Etheruem ecosystems. He mentioned that, as a result of rollups, “block production is centralized, block validation is trustless and highly decentralized, and censorship is still prevented.”

  • Litecoin

Litecoin MimbleWimble November recap update was released. As the updated roadmap shows,
The first Litecoin release containing MWEB code, and the following miner signaling are expected to happen in January 2022.
