// Blockchainer is an interface that abstract the implementation
// of the blockchain.
type Blockchainer interface {
core: implement basic policying support, fix #370 Implement mempool and consensus block creation policies, almost the same as SimplePolicy plugin for C# node provides with two caveats: * HighPriorityTxType is not configured and hardcoded to ClaimType * BlockedAccounts are not supported Other than that it allows us to run successfuly as testnet CN, previously our proposals were rejected because we were proposing blocks with oversized transactions (that are rejected by PoolTx() now). Mainnet and testnet configuration files are updated accordingly, but privnet is left as is with no limits. Configuration is currently attached to the Blockchain and so is the code that does policying, it may be moved somewhere in the future, but it works for now.

Implemented rpc server method GetRawTransaction (#135) * Added utility function GetVarSize * 1) Added Size method: this implied that Fixed8 implements now the serializable interface. 2) Added few arithmetic operation (Add, Sub, div): this will be used to calculated networkfeeand feePerByte. Changed return value of the Value() method to int instead of int64. Modified fixed8_test accordingly. * Implemented Size or MarshalJSON method. - Structs accepting the Size method implement the serializable interface. - Structs accepting the MarshalJSON method implements the customized json marshaller interface. * Added fee calculation * Implemented rcp server method GetRawTransaction * Updated Tests * Fixed: 1) NewFixed8 will accept as input int64 2) race condition affecting configDeafault, blockchainDefault * Simplified Size calculation * 1) Removed global variable blockchainDefault, configDefault 2) Extended Blockchainer interface to include the methods: References, FeePerByte, SystemFee, NetworkFee 3) Deleted fee_test.go, fee.go. Moved corresponding methods to blockchain_test.go and blockchain.go respectively 4) Amended tx_raw_output.go * Simplified GetVarSize Method * Replaced ValueAtAndType with ValueWithType * Cosmetic changes + Added test case getrawtransaction_7 * Clean up Print statement * Filled up keys * Aligned verbose logic with the C#-neo implementation * Implemented @Kim requests Refactor server_test.go * Small fixes * Fixed verbose logic Added more tests Cosmetic changes * Replaced assert.NoError with require.NoError * Fixed tests by adding context.Background() as argument * Fixed tests
