However, for first-round development, using the public blockchain or even the testnet is not always ideal due to long transaction confirmation times. Since we planned to leverage smart contracts, we opted for an Ethereum blockchain. The idea was to store someone’s proof of age, which a bartender or sales clerk could reference in lieu of a physical ID such as a driver’s license.
#ETHEREUM GETH INSTALL VERIFICATION#
My group chose to implement an identity verification system built on the blockchain. This year, we had many blockchain hackathon projects - and we think this speaks to both the growing interest in blockchain by our staff and the potential for companies to benefit from it. Every year, ArcTouch brings together its employees for a three-day hackathon, where groups set out to prototype an idea using new and emerging technologies.
geth export FILEPATH: export a copy of the Blockchain data to FILEPATH geth -lightpeers VALUE: set maximum number of light node peers, default 100
#ETHEREUM GETH INSTALL FULL#
geth -maxpeers VALUE: set maximum number of full node peers, default 25 geth -cache VALUE: increase the amount of memory allocated to geth, default 1024 (MB)
geth account list: list all accounts located in the keystore folder geth account new: create an account, yields the address and location of the keystore file You can expect it to take anywhere from 3 to 12 hours to fast sync your Ethereum node depending on your hardware and whether your connection to the Internet is a bottleneck.Ī few interesting commands which will enhance your geth experience: From then on, it is actively subscribed to updates by the full nodes. When using a light client, beware that it can take up to 10 minutes after the node's initialization before it starts receiving updates from the network. In the folder extracted from the downloaded archive, the geth program can be run with the desired sync mode and other options./geth -syncmode "option" When offering services to users which might require complete records, the fast sync options are the best to use.Ī fast sync node can operate in light mode. The light node gets updated by full nodes once in a while with information on changes pertaining to relevant parts of the Blockchain. If running on a device with low bandwidth or memory, the light node can be advantageous. The drawback to this method is that the node is unable to perform reliable validation, as it doesn't have complete records of the Blockchain. When using "light" synchronization, the node only downloads a few recent block headers, making it a very quick sync. Once the node is in sync, it will continue full validation of new transactions. This is not advised, as it doesn't provide any benefits and can result in the node taking multiple days, or even weeks, to synchronize completely. When using "full" synchronization, the node validates every transaction from downloaded blocks until it reaches the tip of the Blockchain. Once your node is in sync with the rest of the network, the node will validate transactions exactly like a full node. When using "fast" synchronization, the node will initially download blocks until it reaches the tip of the Blockchain without performing extensive validation steps. There are a few options you can use to specify the sync mode of the geth client:īy default, geth will run in -syncmode "fast", this is the recommended option for running a complete Ethereum node. The first step in running an Ethereum node is synchronizing the Blockchian. There are no system dependencies if using an officially released geth binary, which ships for most architectures and operating systems.

Extract the compressed archive with your tool of choice.Fast SSD with at least 500GB free spaceįor light nodes, the requirements are much lower, as you will only be storing block headers and receive small state updates.320GB free storage space to sync the Mainnet.
