blockchain – What happens if I lose Bitcoin Investment, is there Bitcoin insurance?

If fiat bank money is stolen, or bank is fire/damaged, we have banking insurance. If hard money gold is stolen, it can always be replenished with Lloyds of London insurance, or with a mining annual growth rate of 2% per year.

If Bitcoin money is hacked (as it was in past), USB Drive destroyed, or the bitcoin is missing, how can a person recoup their losses?

Some of us agree, slight inflation 1-2% helps insure against losses (just like FDIC insurance, or gold insurance). Of course large inflation, where governments finance war, pointless government programs with inflation of 20-30% year is too much.

The question is, How will Bitcoin solve the insurance issue? Can be it a good storage of value to families if its lost?

Note: I’m aware fiat or gold insurance, will not work if 3rd party insurance is lacking funds. It can work however, last time, someone stole money from friend’s bank account. Does bitcoin offer any level of insurance?

BitClout Blockchain Explorer: Paired with Bitcoin

I’m gathering a list of Bitcoin /Blockchain APIs/Web (REST) APIs that allow you to do basic blockchain queries through http(s) API calls, such as: getting the balance on an address, getting a list of transactions from or to an address, getting the details (i/o) etc. Where can I find more data? Github?

blockchain – Bitcoin Energy Consumption and Carbon Footprint a good long term investment?

How can Bitcoin a good long term investment, given one transaction is equivalent to carbon footprint of 986,125 Million VISA transactions?

If they use the Lightning network which takes transactions Off the Blockchain, wouldn’t that defeat whole purpose of having ledger transaction?

How could I make my own API to query the blockchain

I’m looking to access transaction history for some specific coins directly from the blockchain. The main reason is that most of current API are not free or don’t provide information for the coins I want.

I’m interested in the Bitcoin block chain but in the BSC as well. And for both I’m having issues understanding if I need to run a node myself in order to retrieve transaction or if some “public” node allow people to query them for information.
On top of that, I can’t find any information related to what would be the way to request information from the node, like using REST or something.
Same goes in the case I want to run the node myself, not much information on what the exposed interface would be etc…

Doesn’t anyone already tried to build his own API on a chain ?

blockchain – Is it safe to stake Ethereum 2?

Ethereum staking is described on Coinbase as having no liquidity currently,

During the initial launch, you will temporarily be unable to trade, send, or sell the amount you have staked.

They go on to say,

Staking can be rewarding, but it also comes with the risk of loss of funds if the validator duties are not met. However, Coinbase will cover these risks (at no extra costs) so more customers have access to staking and the opportunity to earn rewards.

My question is more about what happens if proof-of-stake is found to be insecure, or the coin not-viable. What happens in this event if coins are “staked” on Ethereum 2?

blockchain – 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 the target was 0x00ffff0000000000000000000000000000000000000000000000000000.

This leaves me with a few questions:

  1. Is there a reason to why Satoshi picked this number specifically?
  2. How does this relate to other cryptos?
  3. Is the max target fairly arbitrary so long as the designer is careful not to pick a max target that’s too low?
  4. (3b) If so, does the max target not matter in the same way after the first re-target (i.e., after the first 2016 blocks in bitcoin’s case)?

My reasoning for asking this question is because when I look at the difficulty charts for cryptocurrencies, I’ve been curious if they’re relatable to one-another, that is, if you could reason that because BTC has a difficulty of X and LTC has a difficulty of Y, you could determine which to mine based on difficulty and block reward alone.

blockchain – In case of private data collections how can the nodes that don’t have complete access to the transactions know about the world state?

Hyperledger Fabric offers the ability to create private data collections, which allow a defined subset of organizations on a channel the ability to endorse, commit, or query private data without having to create a separate channel.
In that case, how can the nodes that don’t have complete access to the transactions know about the world state?
Will the world state differ between the organization that has and doesn’t have the access to the private data?
