Samples from resource definition RC holes and from grade control holes were assayed by 50g aqua regia digest and AAS finish. Field duplicates RC only inserted at 1 in Blanks inserted at 1 in Certified standards at 1 in 50 up to ; thereafter at 1 in Internal laboratory standards, duplicates and repeats and various other tests have been carried out throughout the drilling programs.

QAQC shows no bias, but only moderate reproducibility, particularly at high grades. Overall assaying quality is considered acceptable except for the potential smearing in some RC samples that were subsequently removed from the dataset prior to estimation as described above. Verification of sampling and assaying The verification of significant intersections by either independent or alternative company personnel.

The use of twinned holes. Documentation of primary data, data entry procedures, data verification, data storage physical and electronic protocols. Discuss any adjustment to assay data. During , Perseus drilled several diamond core holes to confirm the grade tenor and check RC drill holes suspected of downhole contamination and smearing. Drill hole information for pre RC and diamond core holes was captured at the drill site on paper.

Downhole survey data and collar survey data were provided by drilling contractors and surveyors respectively in digital format. Data for resource definition drill holes are stored in a centralised acQuire database. No adjustments were made to the raw assay data except for the removal of any RC samples with suspected smearing of grades as previously discussed. Top cutting is only applied after database compositing and statistical analysis and prior to resource estimation.

Location of data points Accuracy and quality of surveys used to locate drill holes collar and down-hole surveys , trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control. Data spacing and distribution Data spacing for reporting of Exploration Results.

Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure s and classifications applied. Whether sample compositing has been applied. Data spacing for resource estimation varies from 10 m x 10 m to 20 m x 20 m for most areas of the deposit. Where data spacing is wider to a maximum of 40 m x 40 m , an Inferred classification is used.

Data spacing is sufficient to establish grade and geological continuity appropriate to the resource estimation procedures and classifications applied. Orientation of data in relation to geological structure Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type.

If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. Orientation of drilled section lines is dominantly at right angles to the strike of the geology and mineralisation domains.

Drillholes are angled to cross the sub-vertical dip of the geological domains. Mineralised veins and their alteration selvages occur at various orientations within the overall mineralised zones; the estimation method is considered to account for this.

Sample security The measures taken to ensure sample security. Samples from RC drilling were collected and bagged at drill site during the drilling operation. Dispatch from site to Korhogo Intertek was undertaken by Perseus staff and vehicles. All aspects of the process were supervised by Perseus personnel and limited opportunity exists for tampering with samples.

Audits or reviews The results of any audits or reviews of sampling techniques and data. Steffen Brammer of Perseus reviewed sampling techniques and quality control data during regular site visits between and and considered them adequate. Gary Brabham of Perseus Mining has reviewed sampling techniques and quality control data between and with acceptable conclusions. The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.

The mining permit is valid until 8 August and is renewable. Exploration done by other parties Acknowledgment and appraisal of exploration by other parties. Geology Deposit type, geological setting and style of mineralisation.

Subsequent hydrothermal activities and metasomatism of the granitoids has led to a sericite-carbonate alteration within the intrusive and the more permeable horizons sandstones and conglomerates of the sedimentary rocks, and a low to moderate grade disseminated gold mineralisation. Late-stage high grade Au-As-quartz-carbonate veins exploited the altered and brittle portions of the intrusive and sediments with common occurrences of visible gold.

Drill hole Information A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: easting and northing of the drill hole collar elevation or RL Reduced Level — elevation above sea level in metres of the drill hole collar dip and azimuth of the hole down hole length and interception depth hole length.

If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. Individual exploration results are not being reported in the report to which this table relates. Where aggregate intercepts incorporate short lengths of high-grade results and longer lengths of low-grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail.

The assumptions used for any reporting of metal equivalent values should be clearly stated. Relationship between mineralization widths and intercept lengths These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported.

If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect e. Diagrams Appropriate maps and sections with scales and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.

Other substantive exploration data Other exploration data, if meaningful and material, should be reported including but not limited to : geological observations; geophysical survey results; geochemical survey results; bulk samples — size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.

Further work The nature and scale of planned further work e. Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.

Estimates of Mineral Resources and Mineral Reserves are progressively updated as new information comes to hand. Exploration over satellite deposits is on-going. Data validation procedures used. Perseus carried out detailed validation of the dataset and retains overall responsibility for the reliability of data that inform the resource estimate.

All drill hole data were validated during data entry by Perseus including: Checks for duplicate collars Checks for missing samples Checks for down hole from-to interval consistency Checks for overlapping samples Checks for samples beyond hole depth Checks for inexistent or misspelt log items Check for missing assays Check for down-hole information beyond hole depth.

Additionally, Perseus carried out statistical and visual validation prior to estimation including: Drillholes with overlapping sample intervals. Sample intervals with no assay data. Duplicate records. Assay grade ranges. Collar coordinate ranges. Valid hole orientation data. No irreconcilable issues were found, and the data are considered appropriate for resource estimation. Site visits Comment on any site visits undertaken by the Competent Person and the outcome of those visits. The competent Person Christine Shore conducts regular site visits.

No material issues or risks pertaining to the resource were observed during the site visits Geological interpretation Confidence in or conversely, the uncertainty of the geological interpretation of the mineral deposit. Nature of the data used and of any assumptions made. The effect, if any, of alternative interpretations on Mineral Resource estimation. The use of geology in guiding and controlling Mineral Resource estimation. The factors affecting continuity both of grade and geology.

The geological confidence is moderate to high, due to the mapping of exposures within the Main Pit. Drill hole logs were used to guide 3D interpretation of quartz-feldspar felsic dykes and granite intrusions that are key controls on mineralisation. Drill hole logs were also used to guide interpretations of surfaces delineating interfaces between laterite, completely weathered, transitional and fresh rock weathering horizons.

The factors affecting continuity both of grade and geology are most likely to be associated with structural controls and local complexity, the knowledge of which is limited with the current spacing of information. The broad approach to the mineralisation modelling in the Granite and Sediment units is an attempt to model an unbiased interpretation.

Dimensions The extent and variability of the Mineral Resource expressed as length along strike or otherwise , plan width, and depth below surface to the upper and lower limits of the Mineral Resource. The gold Mineralisation was domained by its host lithology for modelling granite, felsic dykes and sediments. Within the dyke domains, mineralised sediments in the alteration halo of the dykes were included to maintain a minimum width of the wireframes and to maintain continuity along strike.

A minimum of 2 m width was used for the wireframes and samples of grades below the nominal cut-off of 0. The domains trend grid north, extend over 2, metres strike and dip steeply to the west and east with horizontal widths varying between 5 to 30 metres for the dyke associated domains and up to metres in width for the granite domains. Domains are interpreted to a maximum vertical depth of metres. Estimation and modelling techniques The nature and appropriateness of the estimation technique s applied and key assumptions, including treatment of extreme grade values, domaining, interpolation parameters and maximum distance of extrapolation from data points.

If a computer assisted estimation method was chosen include a description of computer software and parameters used. The assumptions made regarding recovery of by-products. Estimation of deleterious elements or other non-grade variables of economic significance e. In the case of block model interpolation, the block size in relation to the average sample spacing and the search employed.

Any assumptions behind modelling of selective mining units. Any assumptions about correlation between variables. Description of how the geological interpretation was used to control the resource estimates. Discussion of basis for using or not using grade cutting or capping. The process of validation, the checking process used, the comparison of model data to drill hole data, and use of reconciliation data if available.

A non-linear method was deemed appropriate after reviewing domain statistics. The minimum number of composites was set at 8 and the maximum number of composites was set at 16 for the first pass. A first pass search ellipse radius was set at 60 m for these domains. A second pass had minimum number of composites set at 5 and the maximum number of composites was set at The second pass search ellipse radius was set at m to ensure all remaining blocks had been estimated.

The CoS process yields a set of array variables, stored in the panel block model, detailing the estimates for tonnage, grade and metal above a range of grade cut-offs. Remaining resource domains were estimated using two metre downhole composite gold grade data into 16 mE x 16 mN x 5 mRL sized panels using Ordinary Kriging OK. Three search passes were used with a 40m radii on the first pass, with the search ellipse doubling in size on successive passes.

Dynamic oriented ellipsoidal search radii of 20m. Three search passes were used with the search ellipse doubling in size on successive pass. Estimation was into blocks 16 mE x 16 mN x 5mRL. Surpac Mining Software and Isatis were used for estimation.

No by-product recoveries were considered. Block model validation was undertaken globally by comparing the mean LUC and OK block grade estimates to the mean of the informing composite grades on a domain by domain basis, visual inspection of the estimated block grades viewed in conjunction with the sample data, using swath plots comparing the LUC and OK gold estimates to the sample data and comparing the LUC and GC Models where the LUC local grade model, based only on the relatively wide spaced RDV data, was compared to the high confidence GC OK estimates within the GC volume.

Moisture Whether the tonnages are estimated on a dry basis or with natural moisture, and the method of determination of the moisture content. Tonnages are reported on a dry basis. Cut-off parameters The basis of the adopted cut-off grade s or quality parameters applied. The 0. Mining factors or assumptions Assumptions made regarding possible mining methods, minimum mining dimensions and internal or, if applicable, external mining dilution. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential mining methods, but the assumptions made regarding mining methods and parameters when estimating Mineral Resources may not always be rigorous.

Where this is the case, this should be reported with an explanation of the basis of the mining assumptions made. Metallurgical factors or assumptions The basis for assumptions or predictions regarding metallurgical amenability. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential metallurgical methods, but the assumptions regarding metallurgical treatment processes and parameters made when reporting Mineral Resources may not always be rigorous.

Where this is the case, this should be reported with an explanation of the basis of the metallurgical assumptions made. Environmental factors or assumptions Assumptions made regarding possible waste and process residue disposal options. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider the potential environmental impacts of the mining and processing operation.

While at this stage the determination of potential environmental impacts, particularly for a green fields project, may not always be well advanced, the status of early consideration of these potential environmental impacts should be reported. Where these aspects have not been considered this should be reported with an explanation of the environmental assumptions made.

Bulk density Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples. The bulk density for bulk material must have been measured by methods that adequately account for void spaces vugs, porosity, etc.

Discuss assumptions for bulk density estimates used in the evaluation process of the different materials. A total of bulk density measurements are available from HQ and NQ drill core using the water displacement method. After discarding possibly erroneous high and low values, mean densities were calculated and applied to each of the weathering horizons: Laterite 1.

Classification The basis for the classification of the Mineral Resources into varying confidence categories. Whether appropriate account has been taken of all relevant factors i. All relevant criteria have been considered in the classification of the Mineral Resources as Measured, Indicated and Inferred. The portions of the MRE classified as Measured have been flagged using an interpreted volume defined by high quality of estimation parameters, which includes an average distance to nearest sample of 7 m and an average distance to all informing samples of 12 m.

The Measured portion of the resource has been drilled on a nominal 6 m x 8 m GC spacing. The portions of the MRE classified as Indicated have been flagged using a sectional interpreted volume defined by medium to high quality of estimation parameters, an average distance to nearest sample of less than 20 m and an average distance to all informing samples of less than 40 m.

The portions of the MRE classified as Inferred represent the material extending down dip within and peripheral to the mineralised Domains. In these portions geological continuity is present but not consistently confirmed by 20 m x 20 m drilling and incorporates volume extensions past the deepest drilling by up to 40 m when the domain is not closed off by drilling.

Trial optimisations have been run at a USD1, gold price to define the base of material potentially mineable by open pit mining. Audits or reviews The results of any audits or reviews of Mineral Resource estimates. The Mineral Resource estimation procedure and results have been internally reviewed.

For example, the application of statistical or geostatistical procedures to quantify the relative accuracy of the resource within stated confidence limits, or, if such an approach is not deemed appropriate, a qualitative discussion of the factors that could affect the relative accuracy and confidence of the estimate. The statement should specify whether it relates to global or local estimates, and, if local, state the relevant tonnages, which should be relevant to technical and economic evaluation.

Documentation should include assumptions made and the procedures used. These statements of relative accuracy and confidence of the estimate should be compared with production data, where available. Although the estimate for gold is without bias, some of the estimated volume however is based on relatively wide spaced data.

The estimate is therefore of moderate confidence and expected to be of moderate relative accuracy at the local SMU scale when drilling density exceeds 20 m x 20 m. Infill grade control drilling will be required to improve the confidence of the local estimate. The LUC estimate has been compared to the OK estimates and in a limited volume to an OK estimate of close spaced grade control drilling.

Differences have been identified; however, these do not exceed expectations and no material issues have been identified in these comparisons and the LUC estimate appropriately represents the source data. Clear statement as to whether the Mineral Resources are reported additional to, or inclusive of, the Ore Reserves.

Mineral Resources quoted in this report are inclusive of Ore Reserves. If no site visits have been undertaken indicate why this is the case. Study status The type and level of study undertaken to enable Mineral Resources to be converted to Ore Reserves. Such studies will have been carried out and will have determined a mine plan that is technically achievable and economically viable, and that material Modifying Factors have been considered. The Mineral Resources have been converted to Ore Reserves by means of a Life of Mine plan including economic assessment.

Ore Reserves are determined from technically achievable pit designs based on Open Pit Optimisation. The designs were assessed to ensure economic viability. Cut-off parameters The basis of the cut-off grade s or quality parameters applied. The cut-off grade is based on the economic parameters developed for the Operation.

The choice, nature and appropriateness of the selected mining method s and other mining parameters including associated design issues such as pre-strip, access, etc. The assumptions made regarding geotechnical parameters e. The major assumptions made and Mineral Resource model used for pit and stope optimisation if appropriate.

The mining dilution factors used. The mining recovery factors used. Any minimum mining widths used. The manner in which Inferred Mineral Resources are utilised in mining studies and the sensitivity of the outcome to their inclusion. The infrastructure requirements of the selected mining methods. The chosen method of mining is conventional open pit mining utilising hydraulic excavators and trucks, mining bench heights of 5 m with 2.

Appropriate mining modifying factors such as ore loss, dilution and design parameters were used to convert the Mineral Resource to an Ore Reserve. The pit slope design assumptions are based on a geotechnical study by George, Orr and Associates. Pit ramps have been designed for a 40 tonne ADT truck fleet and are set at 16 metres dual lane to 10 metres single lane.

Minimum mining width of 40 m was generally applied to the pit cutback designs. Inferred Resources have not been included in this mining study. There are no physical constraints to mining within the lease area. No property, infrastructure or environmental issues are known to exist which may limit the extent of mining within the mining area Metallurgical factors or assumptions The metallurgical process proposed and the appropriateness of that process to the style of mineralisation.

Whether the metallurgical process is well-tested technology or novel in nature. The nature, amount and representativeness of metallurgical test work undertaken, the nature of the metallurgical domaining applied and the corresponding metallurgical recovery factors applied. Any assumptions or allowances made for deleterious elements. The existence of any bulk sample or pilot scale test work and the degree to which such samples are considered representative of the orebody as a whole.

For minerals that are defined by a specification, has the ore reserve estimation been based on the appropriate mineralogy to meet the specifications? The plant has a nominal capacity of 1. The processing test work is representative of the different material types throughout the Mining area.

Details of waste rock characterisation and the consideration of potential sites, status of design options considered and, where applicable, the status of approvals for process residue storage and waste dumps should be reported. No environmental issues are known to exist which will prevent open pit mining and ore processing to continue to operate. Based on testing to date there is no risk of acid rock drainage as any potentially acid generating material is encapsulated within acid neutralising material.

Infrastructure The existence of appropriate infrastructure: availability of land for plant development, power, water, transportation particularly for bulk commodities , labour, accommodation; or the ease with which the infrastructure can be provided or accessed. Water supply for processing plant is from river abstraction, groundwater extracted from dedicated boreholes and decant water for processing plant.

Mining workshops and offices to be established on site Costs The derivation of, or assumptions made, regarding projected capital costs in the study. The methodology used to estimate operating costs. Allowances made for the content of deleterious elements. The derivation of assumptions made of metal or commodity price s , for the principal minerals and co- products.

The source of exchange rates used in the study. Derivation of transportation charges. The basis for forecasting or source of treatment and refining charges, penalties for failure to meet specification, etc. The allowances made for royalties payable, both Government and private. The mining costs are based on schedule of rates provided by Perseus mining contractors and Perseus actual performance.

All other operating costs have been provided by Perseus and its Consultants. Non-deleterious materials have been identified and costed. Gold is the only metal considered in the Ore Reserves. A royalty of 4. Revenue factors The derivation of, or assumptions made regarding revenue factors including head grade, metal or commodity price s exchange rates, transportation and treatment charges, penalties, net smelter returns, etc. The derivation of assumptions made of metal or commodity price s , for the principal metals, minerals and co-products.

Market assessment The demand, supply and stock situation for the particular commodity, consumption trends and factors likely to affect supply and demand into the future. A customer and competitor analysis along with the identification of likely market windows for the product.

Price and volume forecasts and the basis for these forecasts. For industrial minerals the customer specification, testing and acceptance requirements prior to a supply contract. The demand for gold is considered at the gold price used. It was considered that gold will be marketable beyond the processing life. The processing forecast and mine life are based on life of mine plans.

The commodity is not an industrial metal. Economic The inputs to the economic analysis to produce the net present value NPV in the study, the source and confidence of these economic inputs including estimated inflation, discount rate, etc. NPV ranges and sensitivity to variations in the significant assumptions and inputs. A schedule and economic model have been completed by Perseus on a pre-tax basis using the Ore Reserves published in this Statement. The inputs used are as per those stated in the relevant sections of this Statement.

The Base Case results from the financial model confirm that the Project is economically viable. Note that as the gold price changes so too will the economic limits of the pits and their Reserves. Consequently, the size of the Project will therefore adjust to suit the revised economics.

Social The status of agreements with key stakeholders and matters leading to social licence to operate. Perseus has established relevant agreements with local stakeholders. Perseus has and will continue to use skilled expatriate workers and locally sourced skilled workers. The status of material legal agreements and marketing arrangements. The status of governmental agreements and approvals critical to the viability of the project, such as mineral tenement status, and government and statutory approvals.

There must be reasonable grounds to expect that all necessary Government approvals will be received within the timeframes anticipated in the Pre-Feasibility or Feasibility study. Highlight and discuss the materiality of any unresolved matter that is dependent on a third party on which extraction of the reserve is contingent. It is believed that the classification of Ore Reserves as set out in the following sections is reasonable. Classification The basis for the classification of the Ore Reserves into varying confidence categories.

Ore Reserves have been classified based on the underlying Mineral Resources classifications and the level of detail in the mine planning. The Ore Reserve classification is considered appropriate given the nature of the deposit, the moderate grade variability, drilling density, structural complexity and mining history. Audits or reviews The results of any audits or reviews of Ore Reserve estimates. Perseus has completed an internal review of the Ore Reserve estimate.

This checklist has been used as a systematic method to undertake a review of the underlying Study used to report in accordance with the JORC Code. This confirmed that it was suitable for estimation of Ore Reserves. An economic model was prepared that confirmed the Operation to be economically viable. For example, the application of statistical or geostatistical procedures to quantify the relative accuracy of the reserve within stated confidence limits, or, if such an approach is not deemed appropriate, a qualitative discussion of the factors which could affect the relative accuracy and confidence of the estimate.

Accuracy and confidence discussions should extend to specific discussions of any applied Modifying Factors that may have a material impact on Ore Reserve viability, or for which there are remaining areas of uncertainty at the current study stage. It is recognised that this may not be possible or appropriate in all circumstances. The accuracy and confidence of the inputs are, as a minimum, of a pre- feasibility level for the global open pit Ore Reserves.

The key factors that are likely to affect the accuracy and confidence in the Ore Reserves are: Accuracy of the underlying Resource Block Models; Changes in gold prices and sales agreements; Changes in metallurgical recovery; and Mining ore loss and dilution The Ore Reserve has utilised all parameters provided by site as made available.

The accuracy of the underlying Mineral Resources is defined by the Resource Category that the Mineral Resources are assigned to. Only the highest categories of Resource classification, Measured and Indicated, have been used as a basis for estimating Ore Reserves.

This is used to control which mining algorithm you want to work with, which pool you will use, and acts as the hub for controlling your miner. Though these all offer the same basic utility, they can vary considerably in both their efficiency and the additional features they offer.

When selecting your mining software, these are some of the basic considerations you will want to make:. Oftentimes, Bitcoin mining software can be downloaded and used free of charge. However, you will often find that these software programs offer additional features for a fee or donation , while those that are the simplest to use and setup come at a cost. Find out more about the best Bitcoin mining software available in A Bitcoin mining pool is a coordinated group of Bitcoin miners that work together to improve their odds of successfully mining BTC.

The combined efforts of a large number of Bitcoin miners ensures that they are able to discover more blocks than when working alone and hence generate a more stable income. While it is possible to mine Bitcoin solo, doing so is unlikely to ever yield any rewards—unless you are packaging some serious hardware.

Instead, with Bitcoin mining pools, everybody aligns their mining power to the same purpose for the common good of the pool. When mining Bitcoin as part of a pool, you will share in the rewards generated by that mining pool in proportion to your fraction of the hash rate controlled by the pool.

Choosing which pool works best for you will mostly come down to personal preference. But in general, the larger the pool the more consistent your income will be. On top of this, you may want to consider pools based on their task assignment mechanism, minimum payout threshold, fee schedule, and transparency, among other parameters. Additionally, it is important you consider pools that are attempting to help the ecosystem grow. Cloud mining is rapidly gaining popularity as a simpler alternative.

Cloud mining providers are online platforms that allow you to rent computing power used for cryptocurrency mining. This allows you to get started with Bitcoin mining with essentially zero barriers to entry. You simply create an account, choose a mining plan, make your payment, and earn your Bitcoin—completely eliminating the efforts and costs involved in purchasing your own hardware and setting it up.

These platforms either pool mining power from their users, or have their own massive mining operations—leveraging the economies of scale to offer mining power to users at near cost rates. But though these platforms are cheaper to start with, there is no guarantee that they are profitable, and they often require lengthy contracts to get the best rates. As a result, many long-term Bitcoin miners are making five times more profit than they were six months ago.

This may be partly due to a major shortage of new ASICs, thanks to a confluence of supply constraints, overdemand, and major mining operations buying up supplies right out of the gate. As a result, most major ASIC manufacturers and distributors are sold out until mid—including both Bitmain and Ebang, who are sold out until August and May respectively.

On the other hand, this shortage has led to a revival of the ASIC secondary market , with prices for mining hardware soaring on eBay—and some units selling for more than triple their usual price.

Features Long Reads. How to Mine Bitcoin: Beginner's Guide Create an account to save your articles. In brief Bitcoin mining helps to keep the Bitcoin network secure against attacks. To begin, miners are the ones who propose updates to the ledger and only miners who have successfully completed the Proof of Work are permitted to add a new block.

This is coded into the Bitcoin protocol. Miners are free to select valid transactions from a pool of potential transactions that are broadcast to the network by nodes. Such transactions are collected into the 'mempool. This gives rise to the fee market, which helps to ensure the limited block space is used fairly and efficiently.

The first miner to complete the Proof of Work broadcasts her proposed new block to the wider network of nodes who then check to ensure that the block follows the rules of the protocol. The key rules here are 1 all transactions in the block are valid ie.

If it does, nodes send it on to other nodes who complete the same process. In this way, the new block propagates across the network until it is widely accepted as the 'truth. However, it can and regularly does happen that more than one miner completes the Proof of Work at almost the same time and simultaneously broadcasts his new block out to the network.

Moreover, due to network delays and geographic separation, nodes may receive new proposed blocks at slightly different times. Note that one miner's newly proposed block could be slightly different from another's. This is because, as mentioned, miners are the ones who choose which transactions to include in a block - and even though they tend to optimize for profitability, location and other factors introduce variation.

When two miners send out different new blocks, competing versions of the 'truth' begin to propagate across the network. The network ultimately converges on the 'correct' version of the truth by selecting the chain that grows longer at faster rate. Let's break down that last part. Imagine there are two competing chains. Statistically, one of the miners working on version A is likely to complete the Proof of Work first, broadcasting the new version out to the network.

Since nodes always select for the longest chain, version A will quickly come to dominate the network. In fact, the probability that version B will grow faster vanishes exponentially with each additional block such that by the time six blocks have been added, it's a statistical impossibility.

For this reason, a transaction that has been confirmed in six blocks is, for most participants, considered to be set in stone. Note that a block which doesn't end up becoming part of the longest chain version B in our example above is known as an orphan block. It is estimated that such blocks are created between 1 and 3 times per day. Transactions that are included in an orphan block are not lost. That's because if they weren't already included in the version that ends up being the longest chain, they'll end up being added to the next block of the longest chain.

Bitcoin miners are awarded BTC when they find a random number that can only be generated by running the hashing algorithm over and over again. This process is analogous to a lottery where buying more tickets increases your chances of winning. By dedicating more computing power to the hashing algorithm, miners are effectively buying more lottery tickets. The difficulty level for the Proof of Work algorithm is automatically adjusted every 2, blocks, or roughly every 2 weeks. Adjustments are made with the goal of keeping the mining of new blocks constant at 10 minutes per block.

The difficulty adjustment factors in the total volume of computing power, or 'hashpower,' being applied to the hashing algorithm. As computing power is added, the difficulty is increased, making mining more difficult for everyone. If computing power is removed, difficulty is reduced, making mining easier. Note that the difficult adjustment system makes bitcoin mining quite different from the mining of precious metals.

If, for example, the price of gold rises, more miners are enticed to join the market. The addition of more gold miners will inevitably result in more gold produced. By forces of supply and demand, this will eventually lower the market price of gold. In Bitcoin's case, however, the volume of bitcoin produced minted is predetermined by the Bitcoin protocol ie.

Bitcoin mining is legal in most regions, including the US and Europe. In China the legal status of bitcoin mining is currently in a gray zone. Bitcoin mining is a highly competitive industry with narrow profit margins. The primary input is electricity, although significant upfront investments in hardware and facilities for housing the hardware are also required.

The key hardware involved is known as the Application Specific Integrated Circuit ASIC , which is a computing device specialized for running the Bitcoin hashing algorithm exclusively. Profitably relies mainly on consistent access to low-cost electricity applied to the most efficient ASIC hardware. Bitcoin mining is a naturally equilibrating system.

As the price of bitcoin rises, miner margins expand. This entices more miners to join the market. However, new entrants cause the difficulty of minting new blocks to increase. This requires all participants to expend more resources, thereby reducing profitability across the board. Sustained downturns in the price of bitcoin have historically resulted in a portion of miners quitting due to costs exceeding revenue. In most cases, miners sell their earned bitcoins to cover the costs associated with mining.

These costs, then, contribute to the net sell pressure. Miner's attempts to maximize profitability by holding or selling Bitcoin based on market momentum may have an impact on Bitcoin's price volatility.
