Abstract

The disclosed technology is generally directed to blockchain technology. In one example of the technology, a modified block is provided in response to at least an edit transaction that indicates a transaction in an original block in a blockchain. The modified block includes: transactions of the original block except the indicated transaction, a hash of the indicated transaction, and a header that includes a link to a hash of a block that precedes the original block. A new block is provided. The new block includes a reference associated with the edit transaction, and that the reference may include a link to the modified block. Subscription metadata associated with subscribers to changes in the transaction is retrieved from a stored registry. The subscribers are caused to be notified of the edit transaction.
