Making the block reward dependent on the difficulty?

I am looking for papers which discuss, if making the block rewards dependent on the difficulty could be used to curb excessive PoW growth. Idea is that BTC price roughly drives difficulty and energy consumption proportionaly. If the block rewards would decrease with difficulty (like in reward=(a+b/difficulty) with suitable constant values for aand b) then it would become much faster unprofitable to add more hash power, thus curbing the growth of total hash power and energy consumption. This must have been discussed somewhere before, but I can not find anything related.

What does it mean to make mining more difficult?

Really I don't know nothing about bitcoin but now I got curious read something and immediately come to something on mind. I mean, there's a social economic comunity somewhere generating value based on the transactions registered, but as they're cheap and bitcoin wants to add value it adds some senseless? dificulty. By the other way there's a full community of scientists and mathematicians fighting for devealing mysteries of nature and knowledge, but most often they don't have the economic resources for their task, hence there's a lot of simulations and sequances to solve and here we have a lot of…

Cant understand how share difficulty affects my chances in solo mining with a pool

So obviously I am not solo mining bitcoin but I think the underlying principles are the same so you guys could help me out here. I am solo mining ergo on a solo pool (herominers solo pool) What I do not understand exactly is what **share **difficulty is (not to be mistaken with ergo network difficulty which I understand) I mean I hash with 2GH/s on ergo I am able to switch between varying share difficulty (which I have notices goes up to like 80GH difficulty) or choose a constant share difficulty. What I noticed is that if I set…

What is the meaning of difficulty in Bitcoin mining?

I'm a beginner in Bitcoin and Blockchain technology, so I have a question after reading about the difficulty in Bitcoin mining: What the difficulty actually means? I read that A high difficulty means that it will take more computing power to mine the same number of blocks, making the network more secure against attacks However, I don't clearly understand. Ex: When the difficulty is 6, then what I can know from that number? Thank you so much!

While Bitcoin’s Price Slumps the Network’s Mining Difficulty Reaches a Lifetime High

After bitcoin prices took a hit following Tesla’s recent u-turn, Bitcoin’s mining difficulty jumped over 25 trillion, the highest the metric has seen during the protocol’s lifetime. The mining difficulty spike follows the recent 12% difficulty drop the network experienced two weeks ago. Bitcoin’s Mining Difficulty Jumps to 25 Trillion, Could Hit 30 Trillion in Two Weeks After some issues with the Xinjiang grid in China three weeks ago, the overall SHA256 hashrate used by the Bitcoin (BTC) network dropped considerably. This in turn caused the BTC network’s mining difficulty to drop 12.6% when the hashrate lowered. Essentially, BTC’s mining…

Bitcoin difficulty: One block with very high difficulty vs. long chain with accumulated difficulty

First assume the hypothetical scenario, that someone has infinite hashing power, starts with the genesis block and mines one block, that has higher difficulty than the whole "normal" blockchain accumulated. Let's call this one-block blockchain (B) and the regular one (A). Would this be the new "real" blockchain with only 50 BTC in circulation? To extend the question, secondly assume our attacker splits their hash power to mine a whole blockchain with similar length to the current one but higher accumulated difficulty, how would we know if it's the real blockchain? All non-fake transactions are in Blockchain (A). There is…

2021’s Largest Epoch Drop: Bitcoin Network’s Mining Difficulty Dips Over 12%, Hashrate Nears 200 Exahash

Bitcoin’s mining difficulty has seen a massive drop this week, as the metric slid 12.6% and was the largest difficulty drop in 2021. The mining difficulty decline follows the recent electrical outages in China which had affected the network’s hashrate to some degree. Following the difficulty drop, Bitcoin’s hashrate is climbing northbound again nearing the 200 exahash per second zone. Bitcoin’s Mining Difficulty Drops 12% Allowing the Hashrate to Climb Higher On April 18, 2021, Bitcoin.com News and a number of crypto publications reported on Bitcoin’s (BTC) hashrate dropping after reports noted that in China the Xinjiang grid is having…

Isn’t Bitcoin’s hash target supposed to be a multiple of 2?

From Bitcoin's whitepaper I've gathered that the hash of a block must start with a certain number of zeroes. And that this number of zeroes is adjusted every 2 weeks. Consequently the hash target is a multiple of two. Requiring an extra zero for the hash function will divide the hash target by 2. With that being said, in another question on the exchange (How is difficulty calculated?) it appears that the difficulty can be multiplied by fractions (e.g. 40%). Does that mean that the hash targets aren't necessarily multiples of 2? Or is the target rounded to the nearest…

Why Bitcoin Bits (difficulty) adjustment happens at multiples of 2016 block height? Why not every block using previous 2016 blocks?

It is surprising to me that Bitcoin difficulty adjustment happens only at multiples of 2016. I thought it should be a no-brainer... But satoshi was genius and so there must be some reason he did not adjust difficulty at every block. Do we know why we did not adjust difficulty at every block, we just needed to take total block time for previous 2016 blocks as we do at every 2016 block? This issue has become more important because recently network hash-rate crashed because of blackout in Xinjiang China, leading to an increase in block time and, consequently, network fees.…

How is the Max Target of a Genesis Block Decided?

I've been diving into the world of Blockchain and crypto lately, trying to build my understanding of mining specifically. I understand that in POW systems, the difficulty of the first block is 1, and the current difficulty can be seen as being "current difficulty multiples harder than the first block" to mine (aka it scales linearly). What I've been having a hard time figuring out, though, is how the designers of POW systems settled on the maximum target for their first blocks. To quote another stackoverflow answer: Satoshi decided to use 0x1d00ffff as a difficulty for the genesis block, so…

Was Bitcoin originally designed to be easy to mine?

I’ve read that back around early 2009, Bitcoin was so easy to mine that an old laptop could mine hundreds of coins in a day by simply using a CPU. Was this Satoshi’s original idea for how people should mine Bitcoin, or did he try to design the system so that it could eventually be manipulated by GPU and ASIC farms, causing the difficulty to increase significantly?

What stops miners from manipulating “target” difficulty in the block header?

I am relatively new to understanding the fundamentals of the Bitcoin network, and I couldn't find the answer to my question. I understand how mining difficulty/target is decided and calculated in the block header. (hashrate of previous 2015 blocks...) Since the larger the target is, the easier it is to mine the new block, what stops a miner from cheating by giving himself a large target, so that he can mine this new block very fast? Does every node check the target value when they are validating a new block? Thank you
