Your wealth ultimately belongs only to your memory
-------------------------------------------------------
1. Why is the traditional mnemonic storage method highly risky?
1. Copying hazards: Notes may be lost, burned, or peeked at by others.
2. Screenshot risks: Phones may be hacked, cloud sync may leak.
3. Memory blind spots: The human brain forgets, especially information not used for a long time.
Pain point summary: Mnemonics must rely on physical carriers or weak memories, and cannot be long-term bound to individuals.
-------------------------------------------------------
2. Ultimate solution: Encrypt mnemonics with 'life password' and store them in the blockchain
Core logic:
Encryption key: Choose a combination of words you will never forget (like a loved one's name + birthday + hometown Pinyin).
Encryption algorithm: Perform letter-by-letter operations on the mnemonic and key (such as subtraction mod), generating an encrypted string.
On-chain storage: Write the encrypted string into the blockchain (like Ethereum notes, Arweave storage, etc.).
Advantages
✅
No need to write down: The key only exists in your mind, and the encryption result can be publicly stored.
✅
Anti-forgetting: The key is based on life memories (like 'mother's name + first love date').
✅
Anti-tampering: Even if a hacker obtains the encrypted string, they cannot restore it without the key.
3. Specific operation steps (taking English mnemonic as an example)
1. Generate your 'life password'
Rule: Choose 12 words that you will never forget (in Pinyin or English),
For example: zhao chang peng xu ming xing li xiao lai guo hong cai
They are: Zhao Changpeng @cz_binance, Xu Mingxing, Li Xiaolai @xiaolai, Guo Hongcai @ChandlerGuo
zhao chang peng xu ming xing li xiao lai guo hong cai
2. Encrypt the mnemonic (practical example)
Plaintext mnemonic: `west arctic remind mask merge grit come student clump over dial rack`
Encryption process:
Correspond each plaintext word with the key word, convert letters to numbers (a=1 to z=26), subtract letter by letter and take mod 26 (add 26 for negatives), fill with 0 when the key is insufficient, the final result is as follows:
1. west - zhao
w(23)-z(26)=23-26=-3+26→ 23 → w
e(5)-h(8)=5-8=-3+26→ 23→ w
s(19)-a(1)=18 → r
t(20)-o(15)=5 → e
Result: wwre
2. arctic - chang (fill 0 to 6 digits)
a(1)-c(3)=-2 +26→24 → x
r(18)-h(8)=10 → j
c(3)-a(1)=2 → b
t(20)-n(14)=6 → f
i(9)-g(7)=2 → b
c(3)-0=3 → c
Result: xjbfbc
3. remind - peng (fill 0 to 6 digits)
r(18)-p(16)=2 → b
e(5)-e(5)=0 +26 → z
m(13)-n(14)=-1 +26→25 → y
i(9)-g(7)=2 → b
n(14)-0=14→ n
d(4)-0=4 → d
Result: bzybnd
4. mask - xu (fill 0 to 4 digits)
m(13)-x(24)=-11 +26→ 15 → o
a(1)-u(21)=-20 +26→ 6→ f
s(19)-0=19→ s
k(11)-0=11→ k
Result: ofsk
5. merge - ming (fill 0 to 5 digits)
m(13)-m(13)=0 +26→ 26 → z
e(5)-i(9)=-4 +26→22→ v
r(18)-n(14)=4→ d
g(7)-g(7)=0 +26→ 26 → z
e(5)-0=5 → e
Result: zvdzze
Here I won't provide examples, just directly get the final encryption result:
wwre xjbfbc bzybnd ofsk zvdzze iium qfme uktoent qklmp hapr vtme oztk
3. Store the encrypted text in the blockchain
Method 1: Write into Ethereum transaction notes (requires small ETH to pay Gas fee).
Method 2: Store in decentralized storage (like Arweave, IPFS), generating a permanently accessible hash.
Method 3: Write into public variables of a smart contract (requires basic development skills).
4. How to recover the mnemonic?
1. Read the encrypted string from the blockchain.
2. Use the 'life password' to decrypt (e.g., letter by letter addition mod 26).
3. Restore the original mnemonic and recover the wallet.
4. Precautions
The key must be unique: avoid using public information (like 'Zhang San Li Si').
Test the decryption process: Immediately verify whether it can be restored after encryption.
Multi-chain backup: Repeatedly store the encryption results on chains like Bitcoin, Solana, etc.
5. Summary
By binding the mnemonic with the 'life password' and utilizing the immutability of the blockchain, you can:
Completely say goodbye to notes and screenshots, achieving triple protection of 'brain power + mathematics + blockchain'.
Even if forgotten, you can retrieve assets through on-chain records and memory of the key.
Your wealth ultimately belongs only to your memory.
