Popular science article ｜ can Ethereum and Boca use the same address? Moonbeam "unified account" helps you achieve

as everyone knows , We put BTC、ETH And so on . So are these encrypted assets confidential ？ It's not . Blockchain is open source 、 Traceable , And all accounts and transaction records can be queried . therefore , From this perspective, encrypted assets themselves are not encrypted .

What is really encrypted is the management right of digital asset account , The management right of the account is determined by the well-known public key and private key .

What are public and private keys

For example , When you go to the bank to open an account , The bank will provide us with a string of numbers as account numbers , We will set the corresponding password for this account . The public key can be understood as the string of numbers provided to us by the bank , That is, the bank account number that can be disclosed . The private key is the secret password set by us to manage the bank account .

The importance of private keys

Public and private keys are thus like keys to digital asset accounts . Because the private key cannot be changed , The person who gets the private key has the right to execute the account . Once the private key is lost or stolen , Assets are at risk of theft . therefore , The private key is crucial for us to keep our digital assets .

encryption algorithm

From the perspective of encryption technology , The encryption method used in the pairing of public key and private key is called asymmetric encryption algorithm . The corresponding is called symmetric encryption algorithm . Asymmetric encryption algorithm uses public key to encrypt and verify signature , The private key is used to decrypt and sign the transaction . Compared with symmetric encryption algorithm , Asymmetric encrypted courier is slow , But it's safer . This is because asymmetric encryption uses two keys , The server and client keys are different , The private key is on the server , Hackers usually don't get it .

Besides , There are many kinds of encryption algorithms , Remove symmetric encryption and asymmetric encryption algorithms , Hash algorithm is also common 、Base64 etc. . When the platforms of different encryption algorithms interact , Users need to manage multiple sets of complicated accounts and corresponding private keys at the same time . This makes it extremely inconvenient for ordinary users to manage private keys , This leads to a poor user experience .

thus , There is another stumbling block on our way to realize Ethereum migration and cross chain .

Moonbeam Unified account

Ethereum has its H160 Address and ECDSA Private key , But poca Substrate What I have is H256 And its matching 25519 Signature system . This makes it impossible for the two systems to communicate , Therefore, users need to save two sets of addresses and private keys , And the use of pledge can only be realized through complex address transfer operations 、 Management balance 、 Participate in governance and other functions .

To solve this problem ,Moonbeam Created by the team “ Unified account ” emerge as the times require .Moonbeam Unified Ethereum EVM And Boca Substrate Accounts and signatures for both systems （ Public key and private key ）.

With a unified account , Users do not need to transfer balances between two different accounts , All functions can be obtained through one account and one private key . One H160 Addresses can be used, including EVM and Substrate All functions including .Moonbeam The bottom standardized adjustment has been made to the single account , In line with Ethereum H160 Address and ECDSA Private key standard .

Simply speaking ,Moonbeam The unified account is to turn these two sets of private keys into one , Greatly reduce the cost of user account management , Improved transaction convenience and user experience . Developers and community partners can be more friendly 、 Low learning cost local migration and use Dapp application .

Moonbeam Committed to Polkadot Create a fully Ethereum compatible environment , And provide the best user experience . In addition to the basic Ethereum functions , It also provides on Chain Governance 、 pledge 、 Additional functions such as cross chain integration . therefore , Realization Moonbeam The key function of full Ethereum compatibility is to use a unified account system .
