Apa Itu Mining Bitcoin


Sesuai dengan namanya, mining bitcoin bisa diartikan sebagai proses penambangan bitcoin. Mungkin, bagi Anda yang masih awam dengan dunia bitcoin, akan membayangkan penambangan seperti halnya hasil tambang, berupa emas, batu bara, dan mineral selainnya.

Akan tetapi, penambangan bitcoin yang ada di sini dimaksudkan untuk mendapatkan mata uang digital paling terkenal di dunia saat ini, yakni bitcoin. Selain itu, penambangan bitcoin harus menggunakan komputer dengan daya komputasi yang sangat tinggi.

Penambangan bitcoin bukan menggunakan alat-alat berat seperti yang digunakan dalam proses pertambangan batu bara, minyak bumi, atau mineral selainnya. Orang yang melakukan penambangan bitcoin biasanya disebut dengan miner.

Dalam artikel insight kali ini, kami akan sedikit menjelaskan kepada Anda mengenai konsep mining bitcoin dan cara kerja mining bitcoin. Berikut sedikit ulasannya untuk Anda.

Apa Itu Mining Bitcoin?

Mining bitcoin atau proses penambangan bitcoin adalah kegiatan untuk mendapatkan bitcoin dengan menggunakan sistem komputer. Proses penambangan bitcoin ini tidak seperti penambangan mineral yang dibayangkan, tetapi menggunakan komputer dengan daya komputasi yang sangat tinggi.

Akan tetapi, sebelum mengetahui soal penambangan bitcoin atau mining bitcoin ini, Anda perlu mengetahui terlebih dahulu soal blockchain. Singkatnya, blockchain merupakan sekumpulan rantai blok yang berisi komponen-komponen kriptografi.

Komponen-komponen kriptografi inilah yang harus dihadapi oleh seorang penambang dalam proses penambangan bitcoin. Ketika komponen kriptografi tersebut berhasil dipecahkan oleh penambang, maka penambang tersebut akan mendapatkan bitcoin yang diinginkan.

Karena komponen kriptografi yang ada dalam blockchain ini sangat sulit, dibutuhkan komputer dengan daya komputasi tinggi. Selain itu, daya listrik untuk menghidupi komputer ini pun juga harus tinggi karena kinerja yang tinggi untuk memecahkan komponen kriptografi yang sangat sulit.

Penambangan bitcoin atau mining bitcoin memiliki tujuan untuk membuat node bitcoin menjadi mungkin mencapai konsensus yang aman dan tahan gangguan. Selain itu, mining bitcoin bisa dibilang sebagai proses mekanisme memperkenalkan bitcoin ke dalam sistem yang sedang dibuat.

Proses penambangan bitcoin ini memang sangat sulit. Oleh karena itu, tidak sembarangan orang bisa melakukan mining bitcoin. Terlebih lagi, proses penambangan bitcoin membutuhkan biaya yang tinggi. Hal itu dikarenakan mining bitcoin membutuhkan peralatan dan daya listrik yang sangat mahal.

Maka dari itu, Anda yang belum memiliki keahlian dan modal dalam mining bitcoin, lebih baik menggunakan jasa penambang atau yang disebut dengan miner. Para penambang yang sudah ahli dalam bidang mining bitcoin biasanya akan menerima upah berupa biaya transaksi dan komisi dari sejumlah bitcoin yang sedang ditambang.

Bagaimana Cara Kerja Mining Bitcoin?

Sebelum masuk ke proses atau cara kerja mining bitcoin, coba kita cari tahu dulu mengenai hasil dari mining bitcoin. Proses mining bitcoin bisa menghasilkan dua hal yang sangat penting dalam dunia kripto saat ini.

Hasil pertama dari proses mining bitcoin tentunya adalah bitcoin baru itu sendiri yang bisa digunakan dalam transaksi maupun sebagai investasi. Sementara itu, hasil kedua dari proses mining bitcoin adalah jaringan pembayaran bitcoin yang dapat dipercaya dan aman.

Kedua hasil tersebut baru akan bisa terwujudkan jika miner atau penambang bisa memecahkan teka-teki dari komponen kriptografi yang ada di dalam jaringan blockchain itu sendiri.

Untuk alur mining bitcoin sendiri dimulai dari proses verifikasi transaksi yang akan dilakukan apakah valid atau tidak. Jika transaksi sudah valid, proses akan dilanjutkan pada tahap mengumpulkan transaksi-transaksi yang ada tersebut ke dalam satu blok.

Blok yang sudah terisi oleh berbagai transaksi tadi akan dilengkapi dengan hash dari header blok yang sebelumnya sudah ada. Jika sudah, penambang akan menyelesaikan masalah yang disebut proof-of-work atau bukti kerja.

Proof of work sendiri sebenarnya merupakan proses komputasi yang kompleks sebelum memasukkan blok transaksi ke dalam blockchain. Penambang nantinya akan mencoba untuk menghasilkan angka heksadesimal 64 digit yang disebut dengan hash dengan jumlah kurang dari atau sama dengan hash target.

Tingkat kesulitan untuk menyelesaikan ‘masalah’ yang ada di dalam proof of work ini pun saat ini lebih dari 13 triliun. Itu berarti kalau komputer biasa hanya bisa menghasilkan hash di bawah target dengan peluang 1 banding 13 triliun.

Oleh karena itu, dibutuhkan sistem komputer yang tinggi untuk menambang bitcoin agar peluang terwujudnya hash di bawah target bisa lebih tinggi. Namun, bukan tidak mungkin, semakin maju zaman semakin tinggi pula tingkat kesulitan yang akan terjadi.

Penambangan atau mining bitcoin yang semakin kompetitif ini pun akhirnya hanya bisa dilakukan dengan optimal menggunakan ASIC terbaru. Ketika penambang menggunakan komputer desktop, GPU, atau model ASIC lawas, pendapatan yang didapatkan bisa lebih rendah dari konsumsi energi yang digunakan.

Kalau proses penyelesaian proof of work ini sudah selesai, blok transaksi yang tadi kita buat akan secara otomatis ditambahkan ke dalam blockchain dan disebarkan ke dalam jaringannya. Proses rumit inilah yang membuat harga bitcoin menjadi sangat tinggi.

Bitcoin Cloud Mining

Saat ini, ada juga teknologi atau sistem bitcoin cloud mining. Penambang yang memilih menggunakan bitcoin cloud mining akan membeli CPU power dari data center yang menggunakan perlengkapan untuk melakukan aktivitas mining bitcoin.

Jadi, penambang tidak perlu memiliki pengetahuan yang mendalam soal hardware mining dan tidak perlu susah-susah bekerja dekat dengan mesin mining bitcoin secara langsung. Penambang hanya perlu menyewa hash power untuk memproduksi bitcoin.

Biasanya, para penambang seperti ini akan memilih data center di Islandia dan Tiongkok. Hal itu dikarenakan kedua negara tersebut memiliki biaya listrik lebih murah yang bisa menghemat modal dan menambah pemasukan.

Bad guys can’t cash out their loot in 2016 Bitfinex hack

Republished by Plato

Published

on

Assets stolen from Bitfinex crypto exchange in a hacking incident back in 2016 will take over a century to be cashed out, blockchain intelligence firm Elliptic said in its latest report.

On Thursday, the company published a statement about the infamous hack that resulted in Bitfinex losing 120,000 bitcoin (valued today at around $7 billion). It detailed nearly 80% of the illegally obtained funds are still in the hacker(s) wallet.

The remaining 21% have been moved around by the malicious cyber attackers that have only managed to launder 4% of their total haul, which is approximately $270 million.

A roadblock for the attackers

Elliptic pointed out that the reason for their thesis is the evolution of crypto tracking tools, regulations, and law enforcement methodologies that make stolen or ill-gotten digital assets very challenging to cash out today.

The intelligence company explained that the hackers used “peel-chains” to exchange the stolen funds. In this method, crypto tokens are moved around numerous times, moving fast from wallet to wallet, and only a small amount of the bitcoin is “peeled off to their actual destination along the way.”

Back then, it was extremely hard to track crypto-assets laundered using this method. But today, the emergence of automatic tracing systems capable of determining the ultimate source or funds in an address makes the job a lot easier for the authorities.

The hacker after the cyber attack

After the successful attack on Bitfinex in 2016, the laundering process started in 2017 through the largest darknet market that time – Alphabay. Later that year, it was shut down by law enforcement, prompting the move to Hydra – the biggest illegal marketplace today.

Cryptoslate cited part of the report from Elliptic, stating, “After a hiatus in 2019, the launderers returned to Hydra in 2020 and are currently depositing $3 million of the stolen bitcoin every month.”

According to the report, to date, there is now approximately $72 million worth of the stolen cryptocurrency sent to Hydra.

Three reasons why Cardano is going on this price trajectory

Republished by Plato

Published

on

Rising trade volume across spot and derivatives exchanges have supported Cardano’s ongoing price rally over the past few weeks and months. The altcoin, at the time of writing, was trading at the $2.32-level, with the crypto gaining by 20% in 24 hours to touch one ATH after the other. The aforementioned hike in price and trade volume were evidenced by the increase in market capitalization as well.

Thanks to the aforementioned factors, Cardano is now ranked third among the market’s top-10 altcoins, based on data from CoinMarketCap.

What’s more, based on the attached chart, currently there is more ADA staked than in the past 30 days. In fact, it is at nearly half a million. With 100% of its HODLers profitable at the press time price level, ADA’s rally is likely to be a long one, especially with the altcoin’s staking rewards data offering a similar conclusion. With a relatively high percentage of ADA staked, a direct relationship has emerged between staked ADA and ADA’s price.

While the current on-chain sentiment is slightly bearish, the net network growth stood at a positive 5%. Further, while there has been a slow drop in large transactions, that could mean that more retail traders are buying ADA v. HODLers and institutions. Unless trade volume drops and cascading sell-offs occur, the price is likely to hold at its current price level.

In the case of Cardano, the concentration by large HODLers has remained largely below 30% and this is key to its ongoing rally. Top memecoins and altcoins that are rallying like DOGE, LINK, BNB, and ETH, among others, have a high concentration by large traders. This is essential to supporting the price at its key levels.

$80 billion worth of large transactions have transpired over the past week and the inflows are anticipated to increase even more. Less than 15% HODLers have held ADA for over 12 months, despite YTD gains of over 500%. And, ADA’s HODLers are lower in numbers than expected. Ergo, the short-term ROI could be the key reason for the short HODLing duration.

Based on data from Messari, the ROI over the past week was nearly 40%.

In the past year, the ROI was over 700%. This is a relatively high gain for HODLers, despite several dips.

ADA’s latest developments and the increasing demand in the second phase of the altseason make it one of the hottest altcoins to buy and HODL. In fact, one can argue that ADA continues to remain undervalued at the press time price level.

Data shows the ‘Bitcoin price drops ahead of CME expiries’ claim is a myth

Republished by Plato

Published

on

Historically, activity surrounding the Bitcoin (BTC) monthly futures and options expiry has been blamed for weakening bullish momentum. A few studies from 2019 found a 2.3% average drop in BTC price 40 hours before the CME futures settlement date. 

However, as Cointelegraph reported in June 2020, the effect faded away. While 2020 seems to have rejected the potential negative impact of CME expiries, so far, the current year appears to validate the theory. Bitcoin’s price has been suppressed ahead of futures and options expiry in the first three months of 2021.

Some investors and traders have pointed out that Bitcoin’s incredible rally after the recent futures and options expiry dates has become a trend.

BTC has effectively rallied in the days following the expiry, but expanding this analysis uncovers a less-than-satisfactory trend.

Three consecutive events don’t prove a trend

The past 13 months have been nothing short of spectacular for Bitcoin, as the cryptocurrency posted 788% gains. August 2020 turned out to be the worst month, as BTC presented a 7.5% negative performance. Thus, choosing random starting points within the month will likely show a similar positive trend.

For example, if one uses the “last quarter” moon phase as a proxy, the odds that a rally takes place after each event are very high.

As depicted above, indeed, Bitcoin rallied after five out of the last six instances. The only conclusion might be that positive trends are the norm rather than the exception during bull runs.

Although there might be some explanation to the reason behind Bitcoin’s end-of-the-month underperformance, these are only hypotheses.

While market makers and arbitrage desks could benefit from suppressing the price after a rally, other forces, including leverage futures longs and call option holders, would balance that out.

Bitcoin price did not drop in three of the last seven expiries

Therefore, it makes sense to analyze the potential price suppression ahead of the expiry instead of looking for explanations for a rally during a bull market.

Both October and December 2020 expiries failed to present any negative pressure ahead of such dates. Meanwhile, the 12% positive performance on the five days that preceded the most recent April 30 expiry also puts a big question mark on how meaningful the CME event really is.

Considering there hasn’t been a price decrease ahead of monthly futures and options expiries in three of the last seven instances, this evidence should put a nail in the coffin of the unfounded myth.

As mentioned earlier, trying to develop theories on why sellers acted more aggressively on specific dates is unlikely to yield results.

As shown above, Bitcoin’s price failed to underperform in three out of the last seven expiries. A 57% success rate should not define a trend when a positive performance after a specific date has been proven common during a bull run.

The views and opinions expressed here are solely those of the author and do not necessarily reflect the views of Cointelegraph. Every investment and trading move involves risk. You should conduct your own research when making a decision.
