Ada tapi-nya mas, 
Kalau seed electrum kita taruh di bip39 wallet a.k.a iancoleman, maka akan didapat wallet berbeda dengan electrum,
Terima kasih atas koreksinya mas, kesalahan saya tidak sampai memeriksa kesesuaian address wallet yang dihasilkannya.Kalau seed electrum kita taruh di bip39 wallet a.k.a iancoleman, maka akan didapat wallet berbeda dengan electrum,
Tadinya saya kira Electrum balik lagi compatible dengan BIP39 untuk seed yang dihasilkannya sebagaimana pada Electrum sebelum versi 2.0.
itu hanya kebetulan, sebenarnya gak kompatible semua. dari dulu juga gak kompatibel, mnemonic seed electrum tidak bisa dipakai di bip39 wallet.
Nampaknya memang demikian, karena beberapa alasan berikut sehingga Electrum tidak meng-generate BIP39 seedBIP39 suffers the same shortcomings as early Electrum seed phrases:
- A fixed wordlist is still required. Following our recommendation, BIP39 authors decided to derive keys and addresses in a way that does not depend on the wordlist. However, BIP39 still requires the wordlist in order to compute its checksum, which is plainly inconsistent, and defeats the purpose of our recommendation. This problem is exacerbated by the fact that BIP39 proposes to create one wordlist per language. This threatens the portability of BIP39 seed phrases.
- BIP39 seed phrases do not include a version number. This means that software should always know how to generate keys and addresses. BIP43 suggests that wallet software will try various existing derivation schemes within the BIP32 framework. This is extremely inefficient and rests on the assumption that future wallets will support all previously accepted derivation methods. If, in the future, a wallet developer decides not to implement a particular derivation method because it is deprecated, then the software will not be able to detect that the corresponding seed phrases are not supported, and it will return an empty wallet instead. This threatens users funds.
For these reasons, Electrum does not generate BIP39 seeds.
