The pow that each miner performs amounts to finding a value for nonce so that a (chained) hash function of the header has a numerical value that is strictly smaller than the target threshold, i.e., the value defined by nBits. Specifically, nBits defines a 256-bit numerical value using an encoding explained in detail in, while nonce can be chosen freely by the miner. The nBits and nonce fields are the most relevant to the pow. The timeР”Р‡ield contains the Unix epoch time at which each miner started performing theР’В pow, which must be strictly greater than the median time of the previous 11 blocks. The previous block header hash and merkle root hash contain hashes of the headers of previous blocks to ensure that no previous transaction in the blockchain can be modified without also modifying the header of the current block. The version field dictates which version of the block validation rules needs to be followed. Each block in the Bitcoin blockchain has an 80-byte (or 640-bit) header that contains information about the block, as shown in Table I. In order to explain the pow concept in more detail, we use Bitcoin as an example, but we note that many other Bitcoin-derived cryptocurrencies, such as MonaCoin and Vertcoin, use the same header structure. On the other hand, to the best of our knowledge, apart from our own previous work, no hardware implementation of the simplified Lyra2 and Lyra2MOD versions of Lyra2 as used in the Lyra2REv2 and Lyra2REv3 algorithms, respectively, have been reported in the literature. The BLAKE, Keccak, Skein, bmw, and CubeHash hashing algorithms are well-known and have been studied heavily, both from theoretical and hardware-implementation perspectives (e.g., ), as they were all candidates in the SHA-3 competition. The chained structures of Lyra2REv2 and Lyra2REv3 are shown in Fig. A prime example of an ASIC-resistant hashing algorithm is Lyra2REv2 (and its recently introduced Lyra2REv3 modification), which is used by MonaCoin, Verge, Vertcoin, and some smaller cryptocurrencies. Since the cost of manufacturing new ASICs whenever some parameters change is prohibitive, GPU mining of ASIC-resistant cryptocurrencies is generally much more low-risk and cost-effective. ASIC resistance is achieved by using hashing algorithms that are highly serial, memory-intensive, and parameterizable so that a manufactured ASIC can easily be made obsolete by changing some of the parameters. To solve this issue, newР’В pow algorithms have been proposed that aim to be ASIC-resistant. Nowadays, the majority of the computing power on the Bitcoin network is found in large ASIC farms, each operated by a single entity, which makes the decentralized nature of Bitcoin debatable. Eventually, GPU mining was outpaced by FPGA miners, which were in turn surpassed by ASIC miners. Then, GPUs were used to significantly increase the hashing speed.

The first cryptocurrency, i.e., Bitcoin, was initially mined using desktop CPUs. Processing nodes that help to compute the hashes of new blocks are called miners, and are rewarded with a fraction of the cryptocurrency when a new block is accepted into the blockchain.

This is unlikely to happen in practice if the processing power is large enough and is owned by non-colluding entities. The chain with the most cumulative pow is accepted as the correct one, so that an attacker must control more than half of the active processing power on the network to perform a double-spend attack. Cryptocurrencies typically use functions that are limited by the available processing power, the most common approach being that random numbers are appended to a block until its cryptographic hash meets a certain condition (e.g., some of its most-significant bits are equal to 0). For example, the employed function can be limited by the available processing power, the available memory, or the network bandwidth and latency. The pow system requires that new blocks provide proof that a function that requires a significant amount of a limited resource was used to construct them before they get accepted into the chain. Simplified Lyra2 and Lyra2REv2 architectures can be modified with minimalР”В®ffort to also support the recent Lyra2REv3 chained hashing algorithm. Miner chain is shown to be significantly more energy efficient than both a GPUР”Р„nd a commercially available FPGA-based miner. Lyra2REv2 on a Xilinx Multi-Processor System on Chip.
