Nov 23,  · *****UPDATE***** Solo mining has been removed from client. I’ll keep the video up for how it used to work, it might still work for some alt coins (unsure) yo. To mine with your CPU and Bitcoin Core, open up the wallet software: Now click on the Help menu and select Debug Window. Then click on the Console tab—the console will appear. Bitcoin mining is legal and is accomplished by running SHA double round hash verification processes in order to validate Bitcoin transactions and provide the requisite security for the public ledger of the Bitcoin network. The speed at which you mine Bitcoins is measured in hashes per second.

The simplest and earliest method was the now-deprecated Bitcoin Core getwork RPC, which constructs a header for the miner directly. Since a header only contains a single 4-byte nonce good for about 4 gigahashes, many modern miners need to make dozens or hundreds of getwork requests a second.

P2P Network. Edit Page. Solo mining, where the miner attempts to generate new blocks on his own, with the proceeds from the block reward and transaction fees going entirely to himself, allowing him to receive large payments with a higher variance longer time between payments.

Pooled mining, where the miner pools resources with other miners to find blocks more often, with the proceeds being shared among the pool miners in rough correlation to the amount of hashing power they each contributed, allowing the miner to receive small payments with a lower variance shorter time between payments. As illustrated below, solo miners typically use bitcoind to get new transactions from the network.

The mining software constructs a block using the template described below and creates a block header. It then sends the byte block header to its mining hardware an ASIC along with a target threshold difficulty setting. The mining hardware iterates through every possible value for the block header nonce and generates the corresponding hash. If none of the hashes are below the threshold, the mining hardware gets an updated block header with a new merkle root from the mining software; this new block header is created by adding extra nonce data to the coinbase field of the coinbase transaction.

On the other hand, if a hash is found below the target threshold, the mining hardware returns the block header with the successful nonce to the mining software. The mining software combines the header with the block and sends the completed block to bitcoind to be broadcast to the network for addition to the block chain. Pool miners follow a similar workflow, illustrated below, which allows mining pool operators to pay miners based on their share of the work done. The mining pool gets new transactions from the network using bitcoind.

In pooled mining, the mining pool sets the target threshold a few orders of magnitude higher less difficult than the network difficulty. This usually means that the coinbase transaction must pay the pool. The information the miner sends to the pool is called a share because it proves the miner did a share of the work.

By chance, some shares the pool receives will also be below the network target—the mining pool sends these to the network to be added to the block chain. The block reward and transaction fees that come from mining that block are paid to the mining pool. The mining pool pays out a portion of these proceeds to individual miners based on how many shares they generated. Different mining pools use different reward distribution systems based on this basic share system.

In both solo and pool mining, the mining software needs to get the information necessary to construct block headers. This subsection describes, in a linear way, how that information is transmitted and used. However, in actual implementations, parallel threads and queuing are used to keep ASIC hashers working at maximum capacity.

The simplest and earliest method was the now-deprecated Bitcoin Core getwork RPC , which constructs a header for the miner directly. Since a header only contains a single 4-byte nonce good for about 4 gigahashes, many modern miners need to make dozens or hundreds of getwork requests a second. Solo miners may still use getwork on v0. This provides the mining software with much more information:. A complete dump of the transactions bitcoind or the mining pool suggests including in the block, allowing the mining software to inspect the transactions, optionally add additional transactions, and optionally remove non-required transactions.

Other information necessary to construct a block header for the next block: the block version, previous block hash, and bits target. For solo miners, this is the network target.

Using the transactions received, the mining software adds a nonce to the coinbase extra nonce field and then converts all the transactions into a merkle tree to derive a merkle root it can use in a block header. Whenever the extra nonce field needs to be changed, the mining software rebuilds the necessary parts of the merkle tree and updates the time and merkle root fields in the block header. Stratum focuses on giving miners the minimal information they need to construct block headers on their own:.

The parts of the merkle tree which need to be re-hashed to create a new merkle root when the coinbase transaction is updated with a new extra nonce. The other parts of the merkle tree, if any, are not sent, effectively limiting the amount of data which needs to be sent to at most about a kilobyte at current transaction volume.

All of the other non-merkle root information necessary to construct a block header for the next block. Using the coinbase transaction received, the mining software adds a nonce to the coinbase extra nonce field, hashes the coinbase transaction, and adds the hash to the received parts of the merkle tree.

The tree is hashed as necessary to create a merkle root, which is added to the block header information received. Whenever the extra nonce field needs to be changed, the mining software updates and re-hashes the coinbase transaction, rebuilds the merkle root, and updates the header merkle root field.
