BiomapperLogLib
A utility library for the BiomapperLog contract.
Functions
isUniqueInLastGeneration
Determines the uniqueness status of a given address in the current biomapper generation.
This call does not guarantee uniqueness across generations, meaning the same person can pass this check more than once (perform a Sybil-attack): with same biometrics but different account after each generation change. Ensure you are fully understand the implications of generations and the security guarantees they provide, and consider explicitly scoping your uniqueness check by a particular generation.
function isUniqueInLastGeneration(IBiomapperLogRead biomapperLog, address who) external view returns (bool);
Parameters
| Name | Type | Description |
|---|---|---|
biomapperLog | IBiomapperLogRead | The BiomapperLog contract. |
who | address | The address to check for uniqueness. |
Returns
| Name | Type | Description |
|---|---|---|
<none> | bool | A boolean value indicating whether the address is biomapped (true) or not (false). |
countBiomappedBlocks
Counts the number of blocks a user has been biomapped for.
function countBiomappedBlocks(IBiomapperLogRead biomapperLog, address who, uint256 fromBlock)
public
view
returns (uint256 blocks);
Parameters
| Name | Type | Description |
|---|---|---|
biomapperLog | IBiomapperLogRead | The BiomapperLog contract. |
who | address | The address to count. |
fromBlock | uint256 | The starting block number. |
Returns
| Name | Type | Description |
|---|---|---|
blocks | uint256 | The number of blocks the user has been biomapped for. |
firstBiomappedGeneration
Finds the first generation a user was biomapped in.
function firstBiomappedGeneration(IBiomapperLogRead biomapperLog, address who) external view returns (uint256);
Parameters
| Name | Type | Description |
|---|---|---|
biomapperLog | IBiomapperLogRead | The BiomapperLog contract. |
who | address | The address to check. |
Returns
| Name | Type | Description |
|---|---|---|
<none> | uint256 | The block number of the first biomapping for the user, or 0 if never biomapped. |
firstSequentialBiomappedGeneration
Finds the block number of the oldest sequential biomapping for a user.
function firstSequentialBiomappedGeneration(IBiomapperLogRead biomapperLog, address who)
external
view
returns (uint256);
Parameters
| Name | Type | Description |
|---|---|---|
biomapperLog | IBiomapperLogRead | The BiomapperLog contract. |
who | address | The address of the user to check. |
Returns
| Name | Type | Description |
|---|---|---|
<none> | uint256 | The block number of the oldest sequential biomapping for the user, or 0 if not biomapped in the current generation. |
