[Naureen1lightcurve]

Description

Define following constants at the constants.ts

• GENESIS_BLOCK_VERSION with a value of 0 and type uint32
• GENESIS_BLOCK_TIMESTAMP with a value of “TBD” and type uint32
• NUM_INIT_ROUNDS with a value of 2574 and type uint32.
• NUM_BOOTSTRAP_VALIDATORS with a value of 101 and type uint32.
• MODULE_NAME_DEX with a value of “dex” and type string.
• MODULE_NAME_POS with a value of “pos” and type string.
• MODULE_NAME_TOKEN with a value of “token" and type string.
• ADDRESS_LENGTH with a value of 20 and type uint32.
• TOKEN_ID_DEX with a value of TBD and type bytes.
• ALL_SUPPORTED_TOKENS_KEY with a value of EMPTY_BYTES and bytes.
• ADDRESS_VALIDATOR_INCENTIVES with a value of SHA256(b"validatorIncentivesAccount")[:20] and type bytes.
• LENGTH_EPOCH_REWARDS_INCENTIVES with a value of 3153600 and type uint32.
• ED25519_PUBLIC_KEY_LENGTH with a value of 32 and type uint32.
• BLS_PUBLIC_KEY_LENGTH with a value of 48 and type uint32.
• BLS_POP_LENGTH with a value of 96 and type uint32.

Engine Specific Configurable Constants for DEX sidechain

• Chain_ID (as defined here)
• MAX_TRANSACTIONS_SIZE_BYTES with a value of “configurable per chain” and type integer
• MAX_ASSET_DATA_SIZE_BYTES with a value of “18” and type integer
• BLOCK_TIME with a value of “10” and type uint32.
• LSK_BFT_BATCH_SIZE with a value of 103 and type uint32.
• MAX_PARAMS_SIZE with a value of 14336 and type uint32.

Module Specific Configurable Constants for DEX sidechain

• LOCKING_PERIOD_STAKES with a value of 260,000.
• PUNISHMENT_WINDOW_STAKES with a value of 780,000
• TOKEN_ID_POS with a value of TOKEN_ID_DEX
• TOKEN_ID_DYNAMIC_BLOCK_REWARD with a value of TOKEN_ID_DEX.
• ADDRESS_LIQUIDITY_PROVIDER_INCENTIVES with a value of SHA256(b"liquidityProviderIncentivesAccount")[:NUM_BYTES_ADDRESS] and type bytes
• ADDRESS_VALIDATOR_INCENTIVES with a value of SHA256(b"validatorIncentivesAccount")[:NUM_BYTES_ADDRESS] and a value of bytes
• BOOTSTRAP_PERIOD_OFFSET with a value of 259975 and type uint32.

Acceptance Criteria

• Constants are defined in constant.ts file and are easily accessible for the rest of the codebase.
• Constants are clearly named and well-documented to indicate their purpose and usage.
• The code compiles without errors and the sidechain functions as expected when the constants are used.
• All the constants are unit tested.
