As money, security is paramount. Bitcoin is still the safest and most proven crypto, despite what others claim. The network has the most miners, which makes attacking the network next to impossible.
Bitcoin does have a few drawbacks, but these are being fixed 1 by 1. Solutions like SegWit and Lightning Network are major advancements.
There’s nothing wrong ...
Here is a guide: How to Fork Bitcoin (create your own chain).
I really think Bitcoin as a concept is unique and powerful, and the project is well maintained by very talented developers, so I wanted to write this not just to help make it easy to clone, but to help increase understanding of the concepts and how to fully utilize them in other projects. I would ...
I would think it has been asked several times, but not in this detail. The way to use escrow would be a „2 of 3 multisig“ transaction. A search in the forum reveals a lot of links. Also very useful is the wiki and of course the bitcoin.org webpage. There are even wallets providing multisig functions. But still it is not „an easy usecase“. Data has to be ...
Using a multi-signature transaction is a way to escrow; there is also a way to split-key pair a transaction.
But to be honest; Bitcoin, was and still is designed by nature to be used without a trusted 3rd party. So much so it is the central focus of Satoshi Nakamoto's White Paper. I would consider the "Lack of a Third Party" to be the leit motif of his ...
No, and this will not happen in the foreseeable future.
Any given hash calculation will result in any one of 2^256 possible numbers. That means, the odds of finding any one exact number is 1/2^256.
Even at today's hashrate of ~47000000 TH/s, it would take you 7.812×10^49 years to find a preimage for every one of those 2^256 numbers, assuming each hash you ...
The Bitcoin Node is part of the blockchain network. It has nothing to do with markets and trading, and has no concept of a price. As far as the node is concerned, 1 Bitcoin = 1 Bitcoin, and that's it.
If you want historical market prices, you will have to either scrape them from various exchanges yourself, or use a service such as this (I have no ...
You can use any exchange api or cryptocurrency market data api such as:
https://api.coinmarketcap.com/v2/ticker/1/?convert=USD returns the following:
When dealing with a centralised exchange, there are only two points of interaction with the blockchain: Deposits and Withdrawals. In order to process deposits you will need to monitor transactions to certain addresses. A withdrawal can be processed offline with only the signed transaction being broadcast to the network. For safety reasons it is best that ...
The most "profitable" way i can think of doing this is:
1) Your cousin buy BTC with AUD in Australia in some local exchange (preferrable) or at LocalBitcoins.com
2) You sell the BTC in Europe using LocalBitcoins (your cousin will give you the password for his LBC account or transfer the BTCs to your account there). They have a 1% fee for sellers, but you ...
The host running a virtual machine has complete, unfettered access to its guest, there's no breaching or compromising necessary. It provides absolutely no additional security in your described situation. It is likely trivial to access ECDSA private key material even between two unrelated virtual machines on a single host due to sidechannel attacks.
Value is a subjective matter and as such you can't make something be worth something else.
As such, your best bet is to create a cryptocurrency and have all participants agree that it's worth the desired asset.
Every other scheme with oracles and "smart contracts" and whatnots are just an iteration of the previous aforementioned social contract between ...
Ripple is actually a permissioned "chain", even if we stretch what the definition of a chain is. It is run by validators and as far as I know, it is not permissionless (which I equate with "trustless").
I do not see a specific need for a permissionless network to have its own coin or token. It could in theory still be driven on top of an already-existing ...
Your first three questions are questions about what you want to do. We have no way to know what you want to do. Your fourth question is technical:
according to What is proof-of-stake? it was said that someone possessing 1% of the total stakes "mine" 1% of the total blocks, it gets confusing here, if example 1 block contains 100 transaction, so this 1% ...
Depending on where you live there are different options. I would suggest, if in the US, to go with one of the larger platforms like Kraken.com, or CoinBase.com. In these systems you can wire funds (Kraken) or attach to a bank account to purchase currency.
In my experience, CoinBase will be your training wheels. It's hard to see what you're buying/selling ...
Currencies get value from demand and supply not from governments backing them. Currencies have existed long before government's started stamping them out in their own name. The demand for a currency comes from the utility that it offers as a medium of exchange. Even pre-historic humans went out of their way to create currencies because they were useful.
This question might be better for the Ethereum Stack Exchange. ETH developers have created a variety of escrow contracts (eg. this or this). I don't see any reason why your idea couldn't be implemented.
(note: I wanted to post this as comment, but I don't have enough points here.)
Gekko is a similar open source library for Node with similar functionality.
Free version to the previously proposed paid version:
Actually, you CAN get the whole Bitcoin trades history from Bitcoincharts in CSV format here : http://api.bitcoincharts.com/v1/csv/
it is updated twice a day for active exchanges, and there is a few dead exchanges, too.
EDIT: Since there are no column headers in the CSVs, here's what they are ...
Just put up a website cryptoarchive.com.au with the data sets I use for my own modeling. One minute OHLVC data is available for free, tick-level data - very reasonably priced. Data from Binance for now.
