After downloading the MPT, it will replay the new block like a full node (with periodic state storage). In order to speed up the node startup process, Geth further provides a fast synchronization mode, which can download the latest stable block MPT without replaying and maintaining the historical MPT before the block. Generally speaking, it takes several weeks to establish such a node to catch up with the latest state of the network from the genesis block. One problem with running a node by replaying all transactions from the genesis block is that replaying all transactions takes a long time. According to Etherscan data, the current block chain data size of Geth full node is about 1TB. (Note that in order to obtain a state that does not contain any state block, the node must obtain the most recent state before the block and replay the next transaction).īy storing the MPT regularly, the storage size of the state is significantly reduced. Here we give a simplified example in which the node only saves the MPT for every 3 blocks.

In order to solve the problem of the state explosion of archive nodes, Geth’s talented engineers created a new mode called “pruning” mode, which only stores MPT regularly.

Since the archive node will retain all the historical state of all blocks, this means that any update in the MPT will create O(log(N)) internal nodes and will not delete the old internal nodes. The internal nodes maintain the tree structure so that the hash root of the entire tree can be quickly calculated The leaf node is the mapping of address (0x…) => account, where the account stores the balance, nonce, etc. The Ethereum state is a Merkle Patrica tree (MPT) in which So sometimes, we refer to storage explosions as “state explosions.” But why is the state so great? In fact, the archive node executes all blocks and retains all historical data, including:Īmong them, the state is the main component of this 8.7TB. So where does the remaining 8.7TB of data come from? If we further analyze the storage usage, we can find that the block data only accounts for about 300GB of data (from block height 0 to 13.6M), which is much less than 9TB. Since one of the goals of the decentralized blockchain is to allow computers with common configurations to run nodes, it will be difficult to achieve the mandatory requirement of 9TB+ storage on computers with common configurations. The figure below is a chart taken from Etherscan, which illustrates the blockchain data size of an Ethereum full node (archived).įrom the figure, we can see that the scale of node chain data has grown steadily and has now reached ~9TB. However, a key challenge in building a high-performance blockchain is the explosion of storage. The vigorous development of decentralized applications such as DeFi and GameFi has greatly increased the demand for high-performance blockchains with low transaction costs.
