C++ (Cpp) tx_after_fork Examples

Example #1

File: leveldb_validate_block.cpp Project: RagnarDanneskjold/libbitcoin

bool leveldb_validate_block::transaction_exists(const hash_digest& tx_hash)
{
    leveldb_tx_info tx;
    if (!common_->get_transaction(tx, tx_hash, true, false))
        return false;
    return !tx_after_fork(tx, fork_index_);
}

Example #2

File: validate_block_impl.cpp Project: MagnusTiberius/libbitcoin-blockchain

bool validate_block_impl::fetch_transaction(chain::transaction& tx,
    size_t& tx_height, const hash_digest& tx_hash) const
{
    uint64_t out_height;
    const auto result = chain_.get_transaction(tx, out_height, tx_hash);

    BITCOIN_ASSERT(out_height <= max_size_t);
    tx_height = static_cast<size_t>(out_height);

    if (!result || tx_after_fork(tx_height, fork_index_))
        return fetch_orphan_transaction(tx, tx_height, tx_hash);

    return true;
}
