# Disk Space Management

<figure><img src="/files/CQwRv2GRs2UmqSYyYM04" alt=""><figcaption></figcaption></figure>

As the blockchain continues to grow, managing disk space becomes a critical concern for nodes. Satoshi provides guidelines for **reclaiming disk space by allowing nodes to discard spent transactions** that are sufficiently far back in the blockchain. Instead of retaining the entire transaction history, nodes can keep only the hashes of these transactions, which are **necessary to maintain the integrity of the system**.

Satoshi cites **Moore's Law**, which predicts that **computing power will double** approximately every two years, as evidence that **storage concerns will diminish over time**.&#x20;
