it preserves your anonymity and prevents you being tracked across the dapps you use. Whenever you sign in to two different dapps using an II, the dapps see different pseudonyms - i.e.

(This will only take a minute see “ How to use Internet Identity ”.) Internet Identity is a revolutionary new blockchain authentication method, based on advanced cryptography, that allows users to sign-in and authenticate to dapps using devices from YubiKeys to the fingerprint sensor on a MacBook laptop. If you do not have an Internet Identity (or II, pronounced eye-eye), you will first have to create one. Note: To login to the NNS dapp, an Internet Identity is required. We’ll explain each of these sections and offer details that users should consider when using the NNS front-end dapp. Creating canister smart contracts and “cycles”.Voting on proposals submitted to the NNS.Staking ICP inside “voting neurons” to earn rewards.The dapp currently provides functionality in four main areas: For an in-depth overview of the NNS, refer to “ Understanding the Internet Computer’s Network Nervous System, Neurons, and ICP Utility Tokens.”īelow is a quick guide to getting started with the NNS front-end dapp and its key functions.
#KEYSMITH DEFINITION UPGRADE#
It can, for example, upgrade the protocol and software used by the node machines that host the network it can create new subnets to increase network capacity it can split subnets to divide their load it can configure economic parameters that control how much must be paid by users for compute capacity it can, in extreme situations, protect the network from malicious actors and it fulfills many other functions as well. Although it won't effect the outcome of the latter exists statements, it isn't good for performance.The purpose of the NNS is to allow the Internet Computer network to be governed in an open, decentralized, and secure manner - and it has complete control over all aspects of the network. I realised I didn't need the cross join in the recursive definition. simple statement to test recursion above, will be filtering the inclusions here (e.g. = 1 - no point recursing if it's for everyone, as the anchor will pull back everything for us. And all users for those created by admin.ĬROSS JOIN -assume every user is doing every rule at this point (because the recursive statement has to be the first statement), we'll filter later. RulesUserHierarchy(UserId, ManagerId, PushRuleId, OnlyForSubOrdinates) - Gets only subordinates for rules created by managers. I needed to consider the CTE a pre-filter and construct all the details I needed before hand, then do my normal filtering after i.e. I just had to change my thinking, instead of seeing if a user exists under a manager within the where clause. Here is a snippet of the SQL I'm working on. I got there eventually! Thanks guys for the help. INSERT INTO Users (UserId, Name, ManagerId)
Here's a sample script which identifies all users who are under Alice in the hierarchy: CREATE TABLE Users(
The Level column ends up not being very important, but I found it helped when I was writing the query. The CTE would return something like: User Ancestor Level
Then you can use the CTE to filter for ancestors. One way to do this would be to create a recursive CTE that has, for each user, one row for each ancestor of that user in the tree. Is there anyway of making the anchor definition dynamic in compatibility mode 80? Or an alternative approach? don't recurse if the anchor definition matches itself (to avoid an infinate loop). I think what I'm trying to do is: WITH UserHierarchy(UserId, ManagerId) so no column parameters into UDF's for me :-( I'm on SQL 2005 with compatibility mode 80 - so I can't use cross apply.I don't think you can use a CTE in a subquery at all.Ideally I'd like to use a recursive CTE inside a correlated exists subquery on the where clause. I need to be able to do this for a set of users against a set of rules (don't worry about this, but just to give it a bit of context) I have a situation where I need to be able to see if a given person is within a user/manager hierarchy.
