概要

モザイクの送金手数料を肩代わり

Aggregate Transactionは、複数のトランザクションをまとめることができるトランザクションです。これを使って、モザイクを送る際に発生するXEM手数料を、誰かが肩代わりできるそうです。

ですが、MIJIN_TESTでのCatapult Serverは、手数料が無料のため、これが検証できません。

「無いものを誰かが肩代わりする」という点に着目し、別の方法を試してみようと思います。

無いXEMを送る

AliceとCarolとBobが登場人物です。

Aliceは十分な量のXEMを持っており、Carolは10XEMもっています。Bobは、受取人なので、残高はわからなくても大丈夫。

ここで、CarolがBobに100XEM送ることを考える。

すると当然、残高不足で送れないでしょう。

ここで、Aliceがそれを肩代わりします。AliceはAggregate Transactionを作成し、Carolに100XEMを送り、CarolからBobへ100XEM送るようにします。

CarolはそれにCosignすればよいだけです。Bobは何もしなくてよいです。

ここで気になるのが、Aggregate Transactionの内部トランザクションは、順番があるのかどうか。

先にCarolにXEMを送金すれば成り立つこの取引、もし逆だった場合は、当然成り立たないと想定されます。

Carol Cosignature

Carolによって、Cosignature Transactionを送信します。

# node cosign.js
cosignatureTransaction.hash  : undefined
cosignatureTransaction.signer: 543BB01DFEEA0D9A25ADDE515DACC72F2125A8AAE85EDD682D77251E2C4EC174
TransactionAnnounceResponse {
  message: 'packet 501 was pushed to the network via /transaction/cosignature' }

残高不足によりトランザクション失敗

Carolのモニタリング画面に、エラーが表示されました。

# nem2-cli monitor status --profile carol

Failure_Core_Insufficient_Balance、つまり残高不足でエラーとなった。

Carol Cosignature Monitoring

もう１度RESTに問い合わせてみたが、結果は返ってこなかった。

再度Cosignatureはできず、lock fundsはもう回収できないと思う。

# curl http://localhost:3000/account/543BB01DFEEA0D9A25ADDE515DACC72F2125A8AAE85EDD

事後の残高照会

# node disp.js
[1528291031079] Alice(Public) have 409089375 nem:xem
[1528291031079] Bob(Public) have 409090553 nem:xem
[1528291031079] Carol(Public) have 10 nem:xem

結果のまとめ（逆順）

肩代わりはできなかった。

LockFunds Transactionを作成したAliceが10XEM失った。

	Balance
Alice	409089385 → 409089375 nem:xem
Carol	10 nem:xem
Bob	409090553 nem:xem

まとめ

Aggregate Transactionにより、足りないXEMを肩代わりすることができた。

Aggregate Transactionには実行される順番に注意しなければならない。

メインネットでモザイクの送金手数料を肩代わりするシーンを考えると、Lock Funds Transactionがいるので、肩代わり者（Service Provider的な）がAggregate Transactionを送信し、モザイク送りたい人はCosignするだけになると思う。

それか、ネットワークに送信する前に関係者の署名を全部揃えられるならば、Aggregate Completeとなり、Lock Fundsは不要になるので、それを使えないか検討する。

ネットワークタイプをPublicにして動かしたら手数料が発生するのではないだろうか。
