Tenderbake -- Classical BFT Style Consensus for Public Blockchains

The Florence proposal (from Nomadic Labs, Marigold, DaiLambda, and Tarides) is a protocol upgrade focused on implementing improvements such as increasing maximum operation size, gas optimizations, depth first execution order, and the elimination of the test chain activation.

The proposal contains improvements to performance and gas costs, the addition of a so-called "adoption period" to the voting schedule, and two important new features that we have been working on for some time: Sapling (shielded tx), and Tickets.

Delphi makes substantial improvements to the performance of the Michelson interpreter and to the gas model, and thus dramatically improves gas costs on the Tezos blockchain.

Increase the gas limit per block and per operation by 30%, improve the accuracy and resiliency of the formula used for calculating baking and endorsing rewards and fix various small issues

Includes Emmy+, delegatable tz1 addresses, Michelson upgrades to improve compilation from high-level languages, hardened governance mechanisms, and more. Fixes a bug affecting big maps in smart contracts and a minor regression affecting the trace_code RPC.

Athens A proposes two incremental changes: Increase the gas limit by doubling the number of computation steps which can be included in each block.Reduce roll size from 10,000 tez to 8,000 tez
