Beberapa hari lalu saya mencoba dari awal hingga hampir 90% syncronisasi blockchain, namun menemukan yang janggal menurut saya yaitu Hard Disk saya yang digunakan untuk nyimpan data tidak sampai ratusan GB, tapi hanya sekitar 6-7 GB saja. Masalahnya saya lupa apa yang saya setting ketika pertama kali running wallet. Kan seharusnya kalau sudah 90% tersebut, 300 GB, namun kok cuma beberapa GB saja di HD-nya.
Kemungkinan pada saat instalasi tersebut, opsi Prune mode nya aktif. Mengenai besaran file size nya berapa, saya sendiri belum mencoba opsi prune tersebut di Bitcoin Core; Namun dari salah satu thread yang pernah saya baca, setidaknya dibutuhkan
space sekitar 5GB (lebih) dan dari pengujian beberapa user, file size-nya hingga sekitar 99GB:
Prune nodePros:- Required about 5 GB by default (a little it more than 5 GB). [a]
- You don't have store all blockchain database on your computer
- You can run a prune node to get experience and pratice with Bitcoin core without significant pressure on your computer storage space.
[a]: In reality, you will prepare at least a little more than 5GB for your prune node with a minimum storage value for blocks (at 2 GB). They are included by:
- Chainstate: 3.5 GB
- Blocks: 2 GB
- Initial setup: 52.1 MB -snip-
The mobile device I can't update the main drive with more storage but can add the microSD storage. This is a high grade microSD but still more of an experiment, yes.
Looks like 99GB is max for a pruned node. UL speed has fluctuated when using the device. 63% progress into May 2017 blocks, 15 hrs remaining as of now.
You indeed can't retroactively increase the pruned size to restore an older wallet. But for future use, this can help:
I've used Bitcoin Core with "Prune block storage 99 GB" for a while, and that was enough to restore wallets from a long time ago. As long as the wallet.dat is used before your oldest block gets pruned, you have all the blocks needed to completely update that wallet. -snip-
Dan jika membaca keterangan dari bitcoin.org berikut, dimungkinkan pengurangan space disk yang semula lebih dari 350GB menjadi sekitar 7GB, sebagaimana yang dialami agan Chikito di atas:
Lalu saya coba uncentang prune lalu restart wallet, eh malah reindex dari awal (13 years) lagi.
Dari yang saya pahami, kemungkinan itu karena adanya perbedaan kompabilitas dengan Prune mode.
Running a node in pruned mode is incompatible with -txindex and -rescan.
Mungkin beberapa referensi berikut bisa jadi tambahan informasi:
Nodes Types and RolesAlthough nodes in the bitcoin P2P network are equal, they may take on different roles depending on the functionality they are supporting. A bitcoin node is a collection of functions: routing, the blockchain database, mining, and wallet services. A full node with all four of these functions is shown in Figure 6-1.
Figure 6-1. A bitcoin network node with all four functions: wallet, miner, full blockchain database, and network routingAll nodes include the routing function to participate in the network and might include other functionality. All nodes validate and propagate transactions and blocks, and discover and maintain connections to peers. In the full-node example in Figure 6-1, the routing function is indicated by an orange circle named “Network Routing Node.”
