NEO NameSpace

NEO namespace provides APIs for native contracts and verifying digital signature.

Native API ：

API	Description
Neo.Native.Deploy	Deploys and initializes all native contracts
Neo.Native.Call	Invokes native contracts

API	Method Name	Description
Neo.Native.Tokens.NEO	name	Gets token name, ie: NEO
	symbol	Gets token symbol, ie: neo
	decimals	Gets decimals
	totalSupply	Gets the total supply
	balanceOf	Gets balance of the token
	transfer	Transfers the token
	SetGasPerBlock	Sets the number of GAS generated for each block
	GetGasPerBlock	Gets the number of GAS generated for each block
	RegisterCandidate	Registers as a candidate
	UnregisterCandidate	Unregisters as a candidate
	vote	Vote
	GetCandidates	Gets a list of candidates
	GetCommittee	Gets a list of committee members
	unclaimedGas	Gets unclaimed Gas

API	Method Name	Description
Neo.Native.Tokens.GAS	name	Gets token name, ie: GAS
	symbol	Gets token symbol, ie: gas
	decimals	Gets decimals
	totalSupply	Gets the total supply
	balanceOf	Gets balance of the token
	transfer	Transfers the token

API	Method Name	Description
Neo.Native.Policy	getMaxTransactionsPerBlock	Gets max transaction number per block
	getMaxBlockSize	Gets max block size
	GetMaxBlockSystemFee	Gets the maximum system fee for the block
	getFeePerByte	Gets fee per byte
	IsBlocked	Verifies whether the account is blocked
	setMaxBlockSize	Sets the max block size
	SetMaxBlockSystemFee	Sets the maximum system fee for the block
	setMaxTransactionsPerBlock	Sets max transaction per block
	setFeePerByte	Sets fee per byte
	BlockAccount	Sets blocked accounts
	UnblockAccount	Unblocks accounts

API	Method Name	Description
Neo.Native.Oracle	Finish	Invokes the callback function after getting the Oracle response
	Request	Initiates an Oracle request
	Verify	Verifies if the Oracle response transaction is legal

The above API are used for committee members only; ordinary users will fail during the signature verification process.

The source code for the above API can be found under NEO in the ( https://github.com/neo-project/neo/blob/master/src/neo/SmartContract/Native/PolicyContract.cs ).

Crypto API ：

API	Description
Neo.Crypto.ECDsaVerify	Verifies signature of the current script container by public key
Neo.Crypto.ECDsaCheckMultiSig	Verifies multiple signatures of the current script container by public key

The source code for the above API can be found under NEO in the src/neo/SmartContract/InteropService.Native.cs and src/neo/SmartContract/InteropService.Crypto.cs .
