public static Account createAccount(String prikey) throws NulsException {
    ECKey key = null;
    if (StringUtils.isBlank(prikey)) {
        key = new ECKey();
    } else {

            key = ECKey.fromPrivate(new BigInteger(Hex.decode(prikey)));
        } catch (Exception e) {
            throw new NulsException(ErrorCode.DATA_PARSE_ERROR);
        }
    }
    Address address = new Address(NulsContext.getInstance().getChainId(NulsContext.CHAIN_ID), Utils.sha256hash160(key.getPubKey()));
    Account account = new Account();
    account.setEncryptedPriKey(new byte[0]);
    account.setAddress(address);
    account.setPubKey(key.getPubKey());
    account.setEcKey(key);
    account.setPriKey(key.getPrivKeyBytes());
    account.setCreateTime(TimeService.currentTimeMillis());
    return account;
}
