id=\"transaction-journal\">Transaction log<!-- --><\/h2>\n<p><!-- --><\/p>\n<p class=\"chakra-text css-gi02ar\">In the 1.6.x version series of Geth, we unveiled a new transaction pool to mitigate propagation challenges caused by minimum gas-price stipulations. This new pool accepted all transactions irrespective of their pricing, continually retaining the highest paying 4K, while discarding the less expensive ones.<!-- --><\/p>\n<p><!-- --><\/p>\n<p class=\"chakra-text css-gi02ar\">The new pool incorporates a distinct exemption mechanism for local accounts, ensuring that a user&#8217;s own transactions take precedence over external ones, even if they are priced lower than all others. This guarantees that inexpensive transactions do not get excluded from the network during intense usage (e.g., ICO) as long as the originating node stays online.<!-- --><\/p>\n<p><!-- --><\/p>\n<p class=\"chakra-text css-gi02ar\">Geth 1.7.0 advances this protective feature by recording all locally generated transactions to disk and restoring them upon node restart. This ensures that even if the originating node goes offline, lower-cost transactions still have an opportunity to be included when the node reactivates (<!-- --><a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-ug8vf0\" href=\"https:\/\/github.com\/ethereum\/go-ethereum\/pull\/14784\">#14784<!-- --><\/a>).<!-- --><\/p>\n<p><!-- --><\/p>\n<p class=\"chakra-text css-gi02ar\">The transaction log can be extremely beneficial for node operators during software updates, alleviating concerns regarding local transactions being lost. Moreover, the log also serves as a fail-safe mechanism against node failures, ensuring that no transaction information is compromised.<!-- --><\/p>\n<p><!-- --><\/p>\n<h2 class=\"chakra-heading css-1w54o5f\" id=\"rinkeby-updates\">Rinkeby enhancements<!-- --><\/h2>\n<p><!-- --><\/p>\n<p class=\"chakra-text css-gi02ar\">There has been considerable refinement of Puppeth and Rinkeby throughout this release, including improved ethstats logging to detect harmful reporters and IP address blacklisting to restrict their access.<!-- --><\/p>\n<p><!-- --><\/p>\n<p class=\"chakra-text css-gi02ar\">The Rinkeby testnet was also crucial in identifying and rectifying a transaction pool event race that resulted in numerous issues regarding lost transactions and\/or duplicate nonce assignments.
