How do you calculate fees with bitcoind? Here is the transaction id as an example: 10ff046cb00483c4b4222fe3d1798b98d5a17af55ff7fc0a6e1e2398b86c13bd https://ift.tt/2Maf9vK

what's the point of "n" in "vout"? getrawtransaction It seems like "n" is the index, is that true? If that is the case, why is the "n" key necessary? Since it's an array, couldn't you just use the array index? Seems redundant, but i'm sure there's a reason. Thanks https://ift.tt/2n1BUXE

While calculating merkle proof, where are the other hashes being stored? Consider that I have a merkle root made up of transactions A,B,C,D,E,F,G,H. The root is H( H(H(A)+H(B)) + H(H(C)+H(D)) ) + H( H(H(E)+H(F)) + H(H(G)+H(H)) ). Now, I have to verify whether transaction C is part of this root (which it is). I am supposed to get hash of C H(C), which I can using the one-way hash function. But then, after that I must get hash of other values also: H(D), H(H(H(A)+(B))) and so on in order to verify that C is a part of the Merkle tree.... Where do these hash values come from? Are they stored somewhere? If not, how are they dynamically generated? And if all hashes are stored, how do I know that my hash H(C) has to be paired with H(D) and not H(A). Similarly for other levels also. Doesn't storing all hashes defeat the purpose of optimizing space? https://ift.tt/2mW9K03

Allowing Incoming Connection on Bitcoin Core Good Evening, I recently installed Bitcoin Core v0.12.1 on my home server (running Windows 7) and wanted to allow it to accept incoming connections and used the guide found here: https://bitcoin.org/en/full-node#windows-7 to ensure I did everything that was needed. Unfortunately, it hasn't been showing any incoming connection and when I used the connection tool recommended in the guide ( https://bitnodes.21.co/#join-the-network ), it says my server is unreachable. I have already setup port forwarding for port 8333 to both my server's IP address, 192.168.1.105 (wireless) & 192.168.1.129 (ethernet). I ran a port scan on the following websites and they all indicate that Port 8333 is open: Ping.eu Port Check WhatMyIP Port Scanner T1 Shopper Port Scanner (I would provide links for the above scanners, but I cannot post more than 2 links) I also created two rules in Windows Firewall (under Inbound Rules) with the following pro

How can all possible numbers in 256-bit space be squeezed into 160-bit space? Bitcoin addresses are essentially 160-bit hashes of a 256-bit public key. Huh?

Can SPV clients offer "proof of absence" of a transaction? So light SPV clients give the user the ability to obtain merkle proofs (from a full node) that a given transaction is included in a block. Is there some cryptographic mechanism by which an SPV client could obtain proof that a transaction (or type of transaction) is not included in a block, while still being relatively "light" (O(log(n), say)? Asking for a layer 2 solution ;) https://ift.tt/2AmuszZ

Preventing the exposure of public addresses on a website Rather than having a single, fixed address, I want to generate a new address on my website every time a user request comes in. I'm concerned about google or another web crawler indexing my website and tying my Bitcoin address to my website address. I've thought about pregenerating the addresses, storing them in a database, and only showing one to each user. I think there's probably a better way. I use node.js, so a solution using bitcoinjs or another node.js package would be preferable. I would prefer to use multisignature addresses. I would rather not depend on blockchain.info or an exchange - it introduces a single point of failure. https://ift.tt/2LMx923

Adding Dependencies to Bitcoin Core I am currently editing a fork of Bitcoin Core. I have three libraries I would like to add as dependencies. One is my own creation (CPISync) and it depends on a second library (NTL) which in turn depends on a third (GMP). I have looked here and here for ways to add libraries to Bitcoin Core, but neither has proved helpful. Like the first post, I am still seeing Undefined reference to errors every time (and I have tried every permutation to Makefile.am discussed there). Likwise, I have added ntl.mk and gmp.mk files (and successfully run make) like the second advises, but to no avail. My question is: what is the standard procedure for adding libraries to Bitcoin Core? I mean this both specifically to my case and generally for Bitcoin Core, since my many searches this past week have not revealed any semblance of a beaten path. My error looks like this: libbitcoin_server.a(libbitcoin_server_a-net_processing.o): In function `ProcessMessage(CNode*, s

CryptoDredge 0.8.0 Nvidia GPU Miner Now Faster and With Support for Tribus The CryptoDredge miner has started as a faster alternative for Nvidia miners for the Lyra2REv2 algorithm, but since then it has been evolving into a multi-functional miner that supports more algorithms and provides good performance in them as well. The latest version of CryptoDredge brings performance improvements in a few algorithms and also support for the Tribus crypto algorithm. You can expect to get around 15-30% faster hashrate in Allium and Phi2 and about 18-35% faster performance in Lyra2z with the version 0.8.0, depending on your GPUs. Do note that as a result of the increased performance the energy consumption might also increase, so if your GPUs get hotter just decrease the TDP limit a bit. Also you might need to update the video drivers to the latest release if you are using an older version. We are reminding you that CryptoDredge is a closed source miner that comes with 1% built-in developer fee, s

Any API to estimate the miner fee for a Bitcoin raw transaction? Coming from the ethereum development scene, I guess I'm kinda spoiled by the availability of the web3 library which has easy access to the eth.gasPrice and eth.estimateGas methods to get the default gas price and gas limit for raw transactions.

What's the best way to store unspent transaction? AFAIK, To send a raw transaction, which include both input and output. And What if we run it on the local node, we can simply fetch the unspent list by run bitcoin-cli listunspent, but If I just want to create a raw transaction on the client side, I believe the only way it store all the transaction to my local server. and before store it, I should do the following operations: 1.get raw transaction (getrawtransaction) 2.parser raw transaction (decoderawtransaction) 3.get the value of amount, and transaction id 4.put all together insert it into the mysql database The table struct as : mysql> desc t_tx; +---------------+---------------+------+-----+---------------------+-------------------------------+ | Field | Type | Null | Key | Default | Extra | +---------------+---------------+------+-----+---------------------+-------------------------------+ | txid | char(

Could Bitcoin be based on accounts instead, more like banks? In banking, a user's account will have a balance, and when they spend an amount is credited from their balance. For example, the account #310 could have $100, and spending $10 would reduce it to $90. Bitcoin on the other hand makes you spend all $100 from the account in a transaction, but the transaction could have two outputs ($10 and $90 - you would keep control of the new $90 account). Why was Bitcoin set up that way instead of the other way? The other way seems more natural. You'd just sign a transaction as coming from your account and going to someone else's account. https://ift.tt/2v0ztsS

Why A Block have a Merkle root hash? That is the question, why a block needs to have a Merkle root hash, as Iundestand, once a block is mined the hash value of this block is stored at the header of the next one so, it generates the chain. Is some data is changed, the hash will not be the same so, it is possible to notice that some data is changed. So I see that storing the merkle root hash at the header of a block is unuseful as it is doing the same thing as hash pointer of the next block of the chain is doing https://ift.tt/2vjqxhE

What prevents Dash miners from refusing to pay to masternodes? I struggle to understand the repationship between Dash miners and masternodes. The proposition is that masternodes provide additional services to the network and automatically get paid a part (45%) of the block reward. What I don't understand is how this share is enforced. From the Dash whitepaper : When mining on the network, pool software (websites that merge the efforts of individual miners) use the RPC API interface to get information about how to make a block. To pay the Masternodes, this interface must be extended by adding a secondary payee to GetBlockTemplate. Pools then propagate their successfully mined blocks, with a split payment between themselves and a Masternode. What prevents miners from simply ignoring the masternodes and assigning 100% of block reward to themselves? https://ift.tt/2LYdWY0

API Update – September 1st, 2018 Starting from September 1st, 2018, 00:00 UTC , Bitfinex will be implementing a series of changes to the way we manage WebSocket connections to our APIs . As of September 1st, every WebSocket connection will have a limit of 50 subscriptions to market data feed channels (tickers, book, candles, trades, …) . We kindly ask all users to adapt their application setup accordingly to split subscriptions to channels using multiple WebSocket connections. As an example, if you subscribe to all tickers, books, candles, trades channels on a single WebSocket connection, you’ll receive  error:10305 ( docs.bitfinex.com/v2/docs/ws-general#section-error-codes ) to notify the quota if the current WebSocket connection is full. For users, this means handling multiple streams, or running multiple instances and spreading them over different pairs. Implementing this API change results in improved connections for API users, meaning quicker data feeds and optimised trading s

How long does block validation take? Assume a miner receives a new block from a connected peer. Please correct me if I'm wrong: The miner validates the newly received block before using it themself and sending it to their other connected peers. I heard this but it seems to me that it'd be a better strategy to already use the block to mine on top of it because the block header and the proof of work associated with it is very fast to verify and it's highly unlikely someone made a block header with a small hash for an invalid block. So why keep mining on top of the previous block? How long does this process typically take? What does it depend on? Is it done on specialized mining hardware or on a general-purpose CPU? Is it correct that the time block validation takes is linear to the block's + witness's size should segwit activate? Also: How long does it take on average for a block to be propagated through the network? It'd be great if that average is weighted on

Totally Disalusioned By Bitcoin! I signed my wife up with a Bitcoin Wallet account and it was functional. However, after attempting to access it and going through the verification process more times then I can remember. I went to a Ern Free Bitcoin site and even had bitcoin sent to Bitcoin Wallet using my [long] bitcoin number. I attempted to access my account several times but got nowhere. When I attempted to get a new wallet I got a "Big Message"...."You are attempting to steal this site" With that I completely deleted everything related to bitcoin. Now I am having difficulty registering for anything! What is with this??? I feel like I was tried and convicted of a crime that never occurred!!! https://ift.tt/2AjN83j

Significance of the &quot;hash&quot; field reported by the 'bitcoin-cli getblock' command It is stated that the header of a block does not contain a 'hash' field ( see https://en.bitcoin.it/wiki/Block_hashing_algorithm or Antonopolous' Mastering Bitcoin 2nd Ed. ) This makes sense since inlcuding such a field would be self-referential. However, when interrogating the blockchain for info on a specific block for example via 'bitcoin-cli getblock' a 'hash' field is reported: { "hash": "00000000839a8e6886ab5951d76f411475428afc90947ee320161bbf18eb6048", "confirmations": 534047, "strippedsize": 215, . . . Is the "hash" field something that the 'bitcoin-cli' calculates and inserts in situ into the json for informational purpouses OR is it that the "hash" field >is< actually part of the header and my understanding of this aspect is flawe

Creating lage blocks with multiple transactions in regtest mode? I want to create blocks with multiple transactions in regtest mode.

Selection of UTXO with Pending (non-mined) Transactions [duplicate] This question already has an answer here: Is it possible to spend an output that hasn't yet been confirmed? 2 answers I have a theoretical question about Blockchain Wallet implementations. Say wallet A has UTXO's for {50, 30} with ID's {0,1} and wants to send wallet B 2 separate payments of $40 each before any block containing the first transaction can be mined. What is the protocol for handling this? What UTXOs will be referenced as inputs to each transaction? How can the 2nd transaction use the Output of the 1st as its Input if miners can mine any transactions irrespective of order? There must be a selection criteria to avoid unintentional double-spending: simply checking the Blockchain for all UTXOs doesn't account for the latest pending transactions. It seems you must all check the pending transactions before validating any transaction or creating any transaction? https://ift.tt/2LVgTZt

Is auditing a BIP32 tree only possible if it is non-hardened? BIP 32 allows you to to implement the auditor use case : Audits: N(m/*) In case an auditor needs full access to the list of incoming and outgoing payments, one can share all account public extended keys. This will allow the auditor to see all transactions from and to the wallet, in all accounts, but not a single secret key. If I want all my bitcoin transactions to be fully audited, then I would need to give my auditor my master node details. However I obviously don't want to give him my master node secret key since he would be able to steal my money. Thus I could only give the auditor my master public key and the chain code. With that he will be able to derive all public keys and see all my transactions. But that means that my entire tree can only use non-harded BIP-32. Is that correct or am I missing something? https://ift.tt/2mMmS80

Possibility of broadcasting new block to only a fraction of honest nodes? Consider in a block-withholding attack (aka selfish mining attack) , attacker after creating a new block decides to broadcast this new block only to a fraction of network, such that eventually only a part of nodes will receive this new block and the rest of network will not receive it. In my opinion, it will not be possible, because when attacker sends new block to one or some of host nodes, they eventually broadcast this block to whole of network, meaning that eventually all honest nodes will receive this new block. Am I right? or this attacker is able to prevent a fraction of honest nodes from receiving this new block? https://ift.tt/2uROQDS
