When a Parity node no-warp, fast syncs, it starts at the genesis block and works through each consecutive transaction, on a per block basis, until it reaches the latest block. This is a time consuming and storage intensive process. Along the way, it computes and saves all state data for each block.
ETHEREUM LIGHT NODE RUN GETH ARCHIVE
When a Parity node no-warp, archive syncs, it starts at the genesis block and works through each consecutive transaction, on a per block basis, until it reaches the latest best block.
ETHEREUM LIGHT NODE RUN GETH FULL
When a Geth node fast syncs, instead of working through each consecutive transaction, the client downloads the transaction receipts in parallel to all the blocks, then pulls the entire most recent state database, and then switches to full sync mode as described above. When a Geth node full syncs, it starts at the genesis block and works through each consecutive transaction, on a per block basis, until it reaches the latest best block. The way each client actually syncs is a bit more nuanced. The Geth and Parity clients both support quicker synchronization modes, "fast sync" and "warp sync" respectively. State data is allowed to be pruned because when a node holds the record of all historical blocks, it can subsequently recompute any historical state.

The full node theme here is self-evident: all block data from the genesis block to the latest best block with the highest amount of accumulated work is stored on the full node's disk.

* maintains the most recent states, while pruning ancient states * has all historical blocks on disk, from the genesis to latest best block * has recomputed the state of each consecutive block, from the genesis to latest best block * full replay and validation of all transactions, contract deployments, and contract executions, per block, starting at the genesis to the latest best block * full synchronization of the blockchain, from the genesis block to the latest best block with the highest amount of accumulated work Generally accepted criteria of a full Ethereum node: Chaindata is the ever expanding chain from the genesis block to the latest best block. It requires a not insignificant commitment of time and effort, as well as related hardware and bandwidth incurred costs, to support the synchronization and maintenance of a full node.Ī full node is not required to develop on Ethereum.Ī full node will require 80+ GB of disk storage space to store Ethereum's chaindata. You're running a full implementation of the Ethereum network on your machine. Let's walk through them at a high level: Full node Running a full node / light node / test node Ī few new terms here for you to digest.
ETHEREUM LIGHT NODE RUN GETH SOFTWARE
Interoperability within the network is important, and it further boosts the adoption of software such as "remote clients" and "wallets" that improve the general user's experience. There exists a myriad of different clients, many independently developed each with their own feature set, yet they remain interoperable with other Ethereum client implementations. The client diversity we enjoy as Ethereum network participants is indicative of a healthy ecosystem. Source (has been modified from original source)
ETHEREUM LIGHT NODE RUN GETH HOW TO
For this reason, we'll walk through how to run these clients in more detail through this documentation. Geth and Parity are arguably the two most common Ethereum clients. Antonopoulos, "Mastering Ethereum" Section 03 - Clients. As such, they can all be used to operate and interact with the same Ethereum network.Īuthor: Andreas M. While these different clients are implemented by different teams and in different programming languages, they all "speak" the same protocol and follow the same rules. Different Ethereum clients interoperate if they comply with the reference specification and the standardized communications protocols. When we use the word node within this technical documentation, we're referring to an Ethereum client.Īn Ethereum client is a software application that implements the Ethereum specification and communicates over the peer-to-peer network with other Ethereum clients.
