there is a minimum amount of wei required to call the buyVoucher function in the ValidatorShare.sol smart contract.
The minimum amount of wei required is specified by the _minSharesToMint input argument. This input argument represents the minimum number of validator shares that the user wants to mint when they buy a voucher.
The buyVoucher function will only succeed if the number of validator shares that the user mints is greater than or equal to the minimum number of shares specified by the _minSharesToMint input argument.
If the user tries to mint fewer shares than the minimum specified by _minSharesToMint, the transaction will fail and any gas used in the transaction will be lost.
It’s important to note that the actual minimum amount of wei required to call buyVoucher will depend on the exchange rate of Matic tokens and the number of wei per Matic token. This information can be obtained from the Matic Network documentation or by querying the Matic Network blockchain.
Validator shares are a way for users to participate in the Matic Network’s Proof of Stake (PoS) consensus mechanism and earn rewards for helping to secure the network.
In the Matic Network, validator shares represent a fractional ownership stake in a validator node. Validator nodes are responsible for processing transactions and validating blocks on the network. Validators earn rewards in the form of Matic tokens for their work, and users who hold validator shares can earn a portion of those rewards based on their stake.
To participate in the PoS consensus mechanism and earn rewards as a validator share holder, users must first buy validator shares by calling the buyVoucher function in the ValidatorShare.sol smart contract. This function allows users to exchange Matic tokens for validator shares.
Once a user has bought validator shares, they can then stake those shares on a validator node by calling the stake function in the Staking.sol smart contract. This function allows users to delegate their shares to a validator node and start earning rewards.
It’s important to note that validator shares can be bought and sold on the open market, and their value is determined by supply and demand. The value of validator shares can fluctuate based on market conditions and the overall health of the Matic Network.
