Consensus mechanisms | ethereum.org
ethereum.org › en › developersEthereum uses a proof-of-stake-based consensus mechanism that derives its crypto-economic security from a set of rewards and penalties applied to capital locked by stakers. This incentive structure encourages individual stakers to operate honest validators, punishes those who don't, and creates an extremely high cost to attack the network.
EtherType - Wikipedia
en.wikipedia.org › wiki › EtherTypeEtherType is a two-octet field in an Ethernet frame. It is used to indicate which protocol is encapsulated in the payload of the frame and is used at the receiving end by the data link layer to determine how the payload is processed. The same field is also used to indicate the size of some Ethernet frames. EtherType is also used as the basis of 802.1Q VLAN tagging, encapsulating packets from VLANs for transmission multiplexed with other VLAN traffic over an Ethernet trunk. EtherType was first de
Layer 2 | ethereum.org
ethereum.org › en › layer-2Jan 17, 2023 · Ethereum and Bitcoin are both layer 1 blockchains because they are the underlying foundation that various layer 2 networks build on top of. Examples of layer 2 projects include "rollups" on Ethereum and the Lightning Network on top of Bitcoin. All user transaction activity on these layer 2 projects can ultimately settle back to the layer 1 blockchain.
