## Probabilistic Consensus Models

Probabilistic consensus models are validation systems where the finality of a transaction is not absolute but increases in certainty over time as more blocks are appended to the chain. This approach is fundamental to Bitcoin and many other proof-of-work blockchains.

While this model provides high security and decentralization, it introduces uncertainty regarding settlement times, which can be a drawback for high-frequency trading applications. Traders must decide how many block confirmations are sufficient to consider a transaction "final" before proceeding with further actions.

This introduces a trade-off between speed and risk, which must be carefully managed. Understanding these models is essential for anyone operating in a decentralized financial ecosystem.
