+### Definitions
+
+
+* LMD-GHOST: latest message drive greediest heaviest observed subtree, the fork choice rule determining which block is viewed as the current chain head.
+
+* Casper FFG: the finality gadget used in Ethereum PoS which moves blocks from the "proposed" to "justified" to "finalized" stage.
+
+* Gasper: Ethereum’s PoS implementation, a combination of the LMD-GHOST fork choice rule, Casper FFG, and the specific reward/penalty scheme.
+
+* RANDAO: random number generation scheme used to select block proposers, sort validators into committees, etc.
+
+* BLS: cryptographic signature scheme used for validator attestations.
+
+* inactivity leak: validators which don’t submit attestations are penalized if the chain stops finalizing.
+
+* slashing: validators which maliciously propose or attest to multiple blocks at the same height have their stake reduced.
+
+* proposer boost: a modification to LMD-GHOST giving additional weight to blocks proposed earlier in the slot to defend against avalanche attacks, see an explanation of a 7-block reorg in the beacon chain while this update was being rolled out.
