Block confirmations on the Cybrid Platform

Block confirmation basics

Blockchain block confirmations are a critical concept in understanding the security and reliability of
transactions on a blockchain network. When you make a transaction on a blockchain, it is initially added to
a pool of unconfirmed transactions. Miners or validators on the network then select transactions from this
pool to include in a new block, which is added to the blockchain. However, this newly added block is not
considered final or fully secure until it has received a certain number of confirmations.

Here's how block confirmations work:

1. Unconfirmed Transactions: When you initiate a transaction (e.g., sending cryptocurrency), it is
   broadcast to the network and enters the pool of unconfirmed transactions.
2. Inclusion in a Block: Miners or validators select transactions from the pool to include in a new
   block. The block is then mined or validated, and when it's added to the blockchain, your transaction is
   included in that block.
3. First Confirmation: Once your transaction is included in a block, it receives its first confirmation.
   This means that it is part of the blockchain and is considered valid. However, it is still not completely
   secure at this point because the blockchain can be "reorganized" if a longer chain with more proof of work
   is mined.
4. Additional Confirmations: To increase the level of security and reduce the risk of a transaction being
   reversed (e.g., due to a 51% attack or chain reorganization), more confirmations are required. Each new
   block added to the blockchain represents an additional confirmation for your transaction. As time passes,
   the likelihood of a transaction being reversed decreases exponentially.

Block confirmations provide a way to mitigate the risk of double-spending and ensure the integrity of the
blockchain. They give participants confidence that a transaction is irreversible and has been accepted by
the network. As more confirmations accumulate, it becomes increasingly improbable that a malicious party
could alter the transaction history, making it a fundamental security feature of blockchain technology.

Cybrid Platform block confirmation configurations

The Cybrid Platform leverages blockchain confirmations to ensure the integrity of deposits to the platform.
The number of confirmations required varies depending on the asset and network.

The following table describes the Cybrid Platform's block confirmation configuration for each of the networks
supported by the platform.

Once the required number of confirmations is reached, the platform_available field is updated on the
corresponding account. To check this value, use the GET /api/accounts/{account_guid} endpoint.
