Coinbase adds hidden message with political undertones to BTC blockchain on day of IPO

Brian Armstrong previously said companies "with great intentions can sometimes end up creating division and unwelcoming environments internally" by getting involved in politics. The crypto exchange, whose CEO has previously dissuaded employees from expressing political views, started its initial public offering off with a message referencing U.S. President Joe Biden’s stimulus package.  According to Coinbase, the crypto exchange had mining pool F2Pool embed the title of a New York Times article in the Bitcoin (BTC) blockchain at 2:05 PM UTC today. The message in block 679,187 refers to the U.S. Congress passing the American Rescue Plan Act of 2021 on…

how to identify as soon as possible that a new block was mined

From the miner perspective: You have a worker, fetching data from a full-node with getblocktemplate to create a candidate block and push it to the miners, to effective mine it. As soon as your miner is done mining a candidate, it asks for more data. However if the block being mined now, was submitted by another miner, all miners should stop to work in the current block and pull data from worker. How can the worker identify as soon as possible that a new block was mined? Monitor if the height on the results from getblocktemplate changed? Monitor if previous…

How mining works for a new born cryptocurrency

What I have learnt that mining is breaking a block which contains transactions using hashing algorithm (Sorry if this is wrong please do correct me). Now my question is how mining will work for a new born cryptocurrency or for a cryptocurrency using which no transactions are being done? Since no transactions means no new blocks? TIA

Stratum: How many shares should I submit per job?

I'm implementing a bitcoin CPU miner just for fun in python. I've been reading a lot about bitcoin and the protocol pools use for communication and coordinating workers but there is a key concept I haven't explicitly found. The problem (Stratum v1) Jobs keep coming to the worker(which I store in a FIFO), and provided clean_jobs is set to false, when should I get to the next job? With nonce, extranonce, and version and time rolling seems like I would never need to change job(even with the fastest of ASICs). Or is it that once I found a share for…

What is the fraction of the Bitcoin mining-power that might be engaged in Selfish-Mining?

Is there an estimate for the fraction of miners engaged in Selfish Mining within the BTC network? In light of the publication The Impact of Selfish Mining on Bitcoin Network Performance (2021), selfish miners not only gain an extra (unfair) share of the block rewards but also increase the chance of forking the network and implementing double-spending attacks. To accomplish that, a group of mining pools holding ~25% of the mining power would be enough to attack the network. I believe this should get more attention from the community since it represents a significant cut in threshold-security from the famous…

UK Bitcoin mining revenues soar, but China hogs 75% of ‘blood coin’ production

U.K.-based Argo Blockchain just did record revenues, but a new report suggests 75% of Bitcoin mining still takes place in China, where “blood coin” is made. United Kingdom-based Bitcoin (BTC) mining firm Argo Blockchain just recorded the best quarter in its history, generating record revenues for three months straight. Yet despite the burgeoning cryptocurrency mining venture emerging in the west, the vast majority of Bitcoin production still takes place in China, where cheap, coal-powered electricity fuels an untold number of mining rigs. A recent report by Nature.com revealed that as much as 75% of Bitcoin mining takes place in China…

Is the block header in stratum protocol double hashed?

I'm trying to understand how the block header is done when mining in a stratum pool. Should the block header be hashed once or double hashed ? the block header consists of the version, previous hash, merkle root, ntime, nbit, and nonce. right?

What is a correct extranonce2 value in the stratum protocol?

I'm developing a stratum mining client. I read on stratum v1 docs on braiins.com how mining work is done on the stratum protocol and that the coinbase is done by concatenating coinb1+extranonce1+extranonce2+coinb2. At the end, mining work is submitted by sending this JSON: {"params": ["<worker>", "<job_id>", "<extranonce2>", "<ntime>", "<nonce>"], "id": 4, "method": "mining.submit"}. It says that the extranonce2 value is generated by the miner but must be based on the extranonce2 size provided by the pool. The extranonce2_size im getting from the pool is: 4 (4 bytes). So an extranonce2 value of 00000001(in hex) can be valid. However, when i'm…

Mining pools repayment in a coinbase tx

Is it possible to add more outputs than one to the coinbase transaction? And if it is, can miners use them to repay users for renting hash to the pool? I think in this case they know who to pay and this could prevent blocks from being found almost instantly and empty.

How does the mining pool know our hashrate/our share?

Scenario: Person A: has a good mining rig and run for 24 hours and produces: 1000 mega hashes, but found only 1 share. Person B: has a bad mining rig and run for 24 hours and produces: 1 mega hash, but found 1 share on first attempt Question: So, how does mining pool know, if we have actually gone through all the 1000 mega hashes to submit one share to the mining pool (Person A has done more work than person B)? But person B who has low hashing power already found a share but has not done any work…

Links for websites that were used to show miners signaling support for segwit

Anyone got links for websites that were used to show miners signaling support for segwit? or screenshots? Also wanted to confirm if my assumptions are correct about the whole thing: Initially BIP 9 was supposed to activate segwit but there was lot of controversy BIP 91 was proposed but again controversy BIP 148 was proposed and everyone agreed to activate BIP 91 Finally BIP 141 was used to activate segwit

How to convert M-address to L-address (Litecoin)

I decided to mine a litecoin block. I have installed a pool (miningcore) on my computer. In the pool settings, I specified the address MLLJufbZimcHZ4p7JsLnaHGpsEkitEP1Lx. I rented power on Nicehash and found block 1920755. But the block received the address LXf6wSzzJQgXvCXwG2g9c2jFcEEqSZhudF. I don't know how it was transformed, but there is no such address in my wallet. All block explorers, except for explorer.litecoin.net, show balance 0. litecoin.net shows the same balance for both addresses for MLLJufbZimcHZ4p7JsLnaHGpsEkitEP1Lx. How can I access the address LXf6wSzzJQgXvCXwG2g9c2jFcEEqSZhudF? I only have the private key for MLLJufbZimcHZ4p7JsLnaHGpsEkitEP1Lx. There must be a way to convert... Sorry for…
