Hashrate Bitcoin – upaya komputasi yang diperlukan untuk mengamankan jaringan – tertatih-tatih di level tertinggi dalam sejarah, menimbulkan kekhawatiran dari beberapa orang di Twitter tentang percepatan jadwal halving Bitcoin. (hadiah untuk menambang satu blok dibelah dua kira-kira setiap empat tahun).
Haruskah mereka khawatir? Tidak terlalu. Algoritme Bitcoin mencegah percepatan jadwal halving, kata pengembang.
Penambang Bitcoin memproses transaksi dan bersaing untuk menambahkan blok baru ke blockchain Bitcoin kira-kira setiap 10 menit. Beberapa faktor (misalnya, jumlah penambang atau peningkatan teknologi) dapat mengganggu ritme 10 menit tersebut, membuatnya sedikit lebih mudah atau sedikit lebih sulit untuk menambang blok.
Algoritme Bitcoin memantau tingkat kesulitan dan menyesuaikannya setiap 2.016 blok (kira-kira setiap dua minggu) untuk mempertahankan waktu blok 10 menit tersebut.
Algoritme juga mengontrol berapa banyak bitcoin yang diterima penambang sebagai hadiah untuk memproses transaksi dan mengamankan jaringan.
Ketika Bitcoin diluncurkan pada tahun 2009, penambang menerima 50 bitcoin karena berhasil menambang satu blok. Hadiah itu (disebut "subsidi") dibagi dua setiap 210.000 blok (kira-kira setiap empat tahun), dan pengurangan separuh berikutnya akan dilakukan pada tahun 2024.
Jadi bisakah lonjakan hashrate mendorong tanggal itu ke 2023 seperti yang diklaim beberapa orang? Jawaban singkatnya adalah, tidak.
Perubahan hashrate tidak akan secara signifikan mengubah jadwal separuh Bitcoin karena algoritme Bitcoin mencegah variasi liar dalam waktu blok dengan menyesuaikan kesulitan agar sesuai dengan kondisi eksternal apa pun yang ada saat itu.
Mungkin ada sedikit perubahan tanggal di sana-sini, tetapi tidak ada yang cukup signifikan untuk mendorong jadwal pengurangan separuh dari 2024 ke 2023.
