From 388cb85406ca8680c16f8ea9996a7a046d993716 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Mon, 22 Dec 2025 18:20:10 +0000 Subject: [PATCH 1/5] feat(nodeminer): Cache block info to speed up mining This change introduces caching for block information to improve the performance of the nodeminer. By caching the mining info, the miner can now check for new blocks after every hash, making it much faster to start working on a new block. The `Blockchain::getMineInfo` method has been refactored to use a cache, and the `NodeMiner` has been updated to check for new blocks more frequently. --- include/class/Block.php | 2 +- include/class/Blockchain.php | 8 +++++++- include/class/NodeMiner.php | 17 +++++++---------- 3 files changed, 15 insertions(+), 12 deletions(-) diff --git a/include/class/Block.php b/include/class/Block.php index 5239fe76..ca6f9dce 100755 --- a/include/class/Block.php +++ b/include/class/Block.php @@ -191,7 +191,7 @@ public function add(&$error = null, $syncing=false) Cache::set("current", $this->toArray()); Cache::set("height", $this->height); Cache::set("current_export", Block::export($hash)); - Cache::set("mineInfo", Blockchain::getMineInfo()); + Cache::set("mineInfo", Blockchain::calculateMineInfo()); Masternode::resetVerified(); diff --git a/include/class/Blockchain.php b/include/class/Blockchain.php index aca98560..f38e844b 100644 --- a/include/class/Blockchain.php +++ b/include/class/Blockchain.php @@ -30,7 +30,7 @@ static function getAvgBlockTime($blocks) { return $elapsed / $blocks; } - static function getMineInfo() { + static function calculateMineInfo() { global $_config; $diff = Block::difficulty(); $current = Block::current(); @@ -55,6 +55,12 @@ static function getMineInfo() { return $res; } + static function getMineInfo() { + return Cache::get("mineInfo", function () { + return Blockchain::calculateMineInfo(); + }); + } + static function addBlock(Block $block) { } diff --git a/include/class/NodeMiner.php b/include/class/NodeMiner.php index be38ff5d..acecdeae 100644 --- a/include/class/NodeMiner.php +++ b/include/class/NodeMiner.php @@ -149,16 +149,13 @@ function start($mine_blocks = null, $sleep = 3) { _log("Mining attempt={$this->attempt} height=$height difficulty=$difficulty elapsed=$elapsed hit=$hit target=$target speed={$this->speed} blockFound=$blockFound", 3); $this->miningStat['hashes']++; - $mod = 10+$this->cpu; - if($this->attempt % $mod == 0) { - $info = $this->getMiningInfo(); - if($info!==false) { - _log("Checking new block from server ".$info['block'].
