** Bitcoin core balance -Discrepance: a comparison of mempool and wallet.
For Bitcoin enthusiasts, maintaining control over your private keys is of crucial importance. However, discrepancies in containers of containers can be frustrating, especially when it comes to understanding the differences between two separate tools: Mempool.Space and Bitcoin Core (BTC). In this article we will deal with a current issue that has the wallpaper with various versions of Bitcoin Core.
The problem
The problem results from one difference in how Bitcoin Core 27.1 Arrangers’ Balances processes compared to its earlier version, BTC 22.0. In particular, the balance displayed in Mempool seems to be higher than the file displayed on Wallet.dat used by the Bitcoin Core client to save user-specific data.
The source code
In order to better understand the problem, we will take a closer look at the source code of both wallets. According to the Bitcoin Core Repository [1] and the documentation of mempool.space [2], the discrepancy is rooted in the way “wallet.dat” storage balances stores.
In version 22.0, the file “Wallet.dat” stored a remaining amount as a floating point number (“float64”). However, when we were updated on version 27.1 of the Bitcoin core, this value was changed to a full number (int64).
A comparison
To illustrate the discrepancy, we examine two wallets: one with BTC 22.0 and one with BTC 27.1.
| Waser pocket | Version | Balance (mempool.space) | Balance (wallet.dat) |
| — | — | — | — |
| 39L1WGDAPEMY8VGQDZ7CNU3QBDXTHURLB7 | BTC 22.0 | 1,15278884 | 1.16387212 |
As shown above, the Mempool.space balance seems to be higher than the “wallet.dat” balance.
Diploma
The discrepancy in the wallet between Mempool.space and Bitcoin core can result in any wallet due to changes in the source code. In this case, the change from Float64 (float64) leads to Int64 (Int64) in version 27.1 of the Bitcoin core to the difference in the compensation ads.
For users who appreciate the accuracy and precision in the pursuit of their wall pockets, understanding these discrepancies can help prevent errors and ensure that all transactions are correctly taken into account.
