Functions

func BuildDualFeePoolSpendTX 

func BuildDualFeePoolSpendTX(
	A_Tx *tx.Transaction,
	totalAmount uint64,
	serverAmount uint64,
	endHeight uint32,
	clientPrivateKey *ec.PrivateKey,
	serverPublicKey *ec.PublicKey,
	isMain bool,
	feeRate float64,
) (*tx.Transaction, *[]byte, uint64, error)

构建双端费用池花费交易 发起者 utxos, 服务器提供金额， 发起者私钥， 服务器地址 fee 是 server 提供，我只负责精确的金额

func BuildDualFeePoolSpendTXWithProof 

func BuildDualFeePoolSpendTXWithProof(
	A_Tx *tx.Transaction,
	totalAmount uint64,
	serverAmount uint64,
	endHeight uint32,
	clientPrivateKey *ec.PrivateKey,
	serverPublicKey *ec.PublicKey,
	isMain bool,
	feeRate float64,
	paymentProof []byte,
) (*tx.Transaction, *[]byte, uint64, error)

BuildDualFeePoolSpendTXWithProof 构建双端费用池付款交易，并支持可选二进制付款证明。

func ClientDualFeePoolSpendTXUpdateSign 

func ClientDualFeePoolSpendTXUpdateSign(
	tx *tx.Transaction,
	clientPrivateKey *ec.PrivateKey,
	serverPublicKey *ec.PublicKey,
) (*[]byte, error)

双端费用池，分配资金, 客户端签名 client -> server 修改金额和版本号

func ClientVerifyServerSpendSig 

func ClientVerifyServerSpendSig(
	transactionObject *tx.Transaction,
	totalAmount uint64,
	serverPublicKey *ec.PublicKey,
	clientPublicKey *ec.PublicKey,
	serverSignBytes *[]byte,
) (bool, error)

ClientVerifyServerSpendSig 用于在 B-Tx 上验证服务器签名。

func ClientVerifyServerUpdateSig 

func ClientVerifyServerUpdateSig(
	transactionObject *tx.Transaction,
	serverPublicKey *ec.PublicKey,
	clientPublicKey *ec.PublicKey,
	serverSignBytes *[]byte,
) (bool, error)

ClientVerifyServerUpdateSig 用于在更新后的 B-Tx 上验证服务器签名。

func DualPoolSpentScript 

func DualPoolSpentScript(
	serverPublicKey *ec.PublicKey,
	clientPublicKey *ec.PublicKey,
) (*script.Script, error)

构建双端费用池的花费脚本

func LoadTx 

func LoadTx(
	txHex string,
	locktime *uint32,
	sequenceNumber uint32,
	serverAmount uint64,
	serverPublicKey *ec.PublicKey,
	clientPublicKey *ec.PublicKey,
	targetAmount uint64,

) (*transaction.Transaction, error)

合成两个签名

func LoadTxWithProof 

func LoadTxWithProof(
	txHex string,
	locktime *uint32,
	sequenceNumber uint32,
	serverAmount uint64,
	serverPublicKey *ec.PublicKey,
	clientPublicKey *ec.PublicKey,
	targetAmount uint64,
	paymentProof []byte,
) (*transaction.Transaction, error)

LoadTxWithProof 在旧更新逻辑上追加“同步可选 proof OP_RETURN”的能力。 设计说明： - paymentProof=nil 时，沿用旧交易里的数据输出，不改动现有 proof； - paymentProof 非 nil 时，会把当前状态 proof 同步到交易最后一个 OP_RETURN 输出； - 这样 BFTP 可以把 proof state 作为共享库挂在状态交易上，而 MultisigPool 仍然保持通用。

func MergeDualPoolSigForSpendTx 

func MergeDualPoolSigForSpendTx(
	txHex string,
	serverSignByte *[]byte,
	clientSignByte *[]byte,
) (*tx.Transaction, error)

从创建花费脚本,客户端签名

func ServerDualFeePoolSpendTXUpdateSign 

func ServerDualFeePoolSpendTXUpdateSign(
	tx *tx.Transaction,
	serverPrivateKey *ec.PrivateKey,
	clientPublicKey *ec.PublicKey,
) (*[]byte, error)

双端费用池，分配资金, server 签名 client -> server 修改金额和版本号

func ServerVerifyClientSpendSig 

func ServerVerifyClientSpendSig(
	transactionObject *tx.Transaction,
	totalAmount uint64,
	serverPublicKey *ec.PublicKey,
	clientPublicKey *ec.PublicKey,
	clientSignBytes *[]byte,
) (bool, error)

ServerVerifyClientSpendSig 用于在 B-Tx 上验证客户端签名。

func ServerVerifyClientUpdateSig 

func ServerVerifyClientUpdateSig(
	transactionObject *tx.Transaction,
	serverPublicKey *ec.PublicKey,
	clientPublicKey *ec.PublicKey,
	clientSignBytes *[]byte,
) (bool, error)

ServerVerifyClientUpdateSig 用于在更新后的 B-Tx 上验证客户端签名。

func SpendTXDualFeePoolClientSign 

func SpendTXDualFeePoolClientSign(B_Tx *tx.Transaction, targetAmount uint64, clientPrivKey *ec.PrivateKey, serverPublicKey *ec.PublicKey) (*[]byte, error)

func SpendTXServerSign 

func SpendTXServerSign(
	transactionObject *tx.Transaction,
	targetAmount uint64,
	serverPrivateKey *ec.PrivateKey,
	clientPublicKey *ec.PublicKey,
) (*[]byte, error)

服务器 回签

func SubBuildDualFeePoolSpendTX 

func SubBuildDualFeePoolSpendTX(
	prevTxId string,
	totalAmount uint64,
	serverAmount uint64,
	endHeight uint32,
	clientPrivateKey *ec.PrivateKey,
	serverPublicKey *ec.PublicKey,
	isMain bool,
	feeRate float64,
) (*tx.Transaction, uint64, error)

多签 to client，server 提供金额

func SubBuildDualFeePoolSpendTXWithProof 

func SubBuildDualFeePoolSpendTXWithProof(
	prevTxId string,
	totalAmount uint64,
	serverAmount uint64,
	endHeight uint32,
	clientPrivateKey *ec.PrivateKey,
	serverPublicKey *ec.PublicKey,
	isMain bool,
	feeRate float64,
	paymentProof []byte,
) (*tx.Transaction, uint64, error)

SubBuildDualFeePoolSpendTXWithProof 构造双端费用池付款交易，并可追加付款证明 OP_RETURN。 proof 为空时不生成数据输出，保持旧交易结构与旧签名语义。
