Should we require asset owner permission to use said asset as backing collateral for an MPA?

Recently, issue #1537 in the bitshares-ui Github repo highlighted the fact that despite the UI and documentation indicating that UIA cannot be used to back an MPA on the BTS DEX, the reality actually is that UIA are an allowed backing collateral asset type in the core code.

This BSIP is not arguing for/against UIA being used as an MPA's backing collateral, because this is already enforced by core (Abit has a testnet asset configured as such).

The purpose of this BSIP discussion is to decide whether or not you should require owner permissions/approval of the asset being assigned as backing collateral for a new MPA.

---

Why I think we should require permission

  • Any assets locked away as MPA backing collateral cannot be reclaimed/recalled by the UIA owner (even by force). This has the consequence of being unable to reduce the supply to 0, potentially preventing asset settings from being changed or the asset from being fully shutdown.
  • By 'wrapping' an UIA in an MPA 'container' the MPA owner can effectively impose new asset settings over the existing UIA flags/permissions/settings to the potential detriment of the UIA owner.

Why perhaps we shouldn't require such permissions


  • An asset owner may refuse (or be unable to) provide permission to use the asset as backing collateral, requiring an alternative asset for backing collateral.
  • The committee may be overwhelmed with requests to use committee owned assets as backing collateral, though that's subjective.
  • The committee would have a greater centralized control of backing collateral selection on the BTS DEX, however that could result in more private MPAs being created. The committee size could be increased too to offset risk.
  • Existing MPA with non-BTS backing collateral may make implementing such a permission requirement too complex? Perhaps existing MPA could be exempt?
  • What if the asset owner removed their approval at a later date? It'd have to be permanent approval unless supply was 0.
  • What happens if you have owner permissions of the backing asset & MPA, then transferred the backing asset ownership to another account?
  • Being able to avoid market fees and replace restrictive permission flags with an MPA is pretty cool.

Exclusions: The Bitshares core token (BTS) should be excluded, as nobody has ownership permissions over it.

What are your thoughts?

Can you think of any reasons for/against requiring permission to use an asset as backing collateral for an MPA?

Hey,

There's a new bitsharestalk forum which is currently running on the beta (pre-production) whaleshares (fork of steemit) network, you should check it out & join the bitsharestalk telegram channel (.io related, not an intended replacement of the main bitshares telegram channels).

Why the whaleshares network? Bitshares is receiving a 70% sharedrop of whaleshares, much better than the 0% sharedrop that Steemit performed (aka they didn't do that). The sharedrop date isn't confirmed yet.

What do you think of this idea? I think it will draw serious activity back to bitsharestalk, this forum has decreased in activity in the last year or so, plus being able to reward each other for posting about the Bitshares network is pretty cool, eh?

I think that in order to join the testnet you need to join the telegram channel and/or attend one of the Bitshares hangouts on saturdays.

https://steemit.com/bitshares/@stan/bitshares-org-gets-long-awaited-face-lift

Stan/Cryptonomex apparently just transferred ownership of bitshares.org to Apasia.tech - a for-profit entity that isn't an active witness/committee member nor a part of the Bitshares foundation.

Is anyone else concerned by this? Wouldn't it have been more appropriate for the ownership transfer to have been made to the committee, witnesses or to the bitshares foundation instead of a private for-profit company?

Take precautions - I'd consider using the light wallet over the reference org wallet until we know what's going on.

Cheers

Stakeholder Proposals / Requesting price feeds for the Hertz ABA
« on: February 27, 2018, 12:34:49 am »
Hertz - Oscillating Algorithm Based Asset

Hertz is an MPA which is modified with a sine wave to predictably oscillate with a 14% amplitude, and 28day period, resulting in a price feed range of $0.86 to $1.14.

Price feed scripts have been created for wackou's bts_tools, xeroc's bitshares-pricefeed and the reference Hertz python-bitshares based price feed implementation.

A $750 (bitUSD) bounty is still available for the implementation of Hertz in the btsprice price feed repo.

I'm seeking additional price feed publishers, I've pre-approved 25 price feed publishers (detailed below) who can begin publishing price feeds for Hertz at their discretion. Any elected witnesses not currently publishing price feeds - I'd greatly appreciate feedback regarding what would help you begin publishing price feeds.

Approved price feed publishers:
fox, wackou, xeldal, xman, abc123, xn-delegate, datasecuritynode, delegate.ihashfury, bhuz, delegate-1.lafona, delegate.freedom, elmato, in.abit, verbaltech2, witness.yao, witness.still, roelandp, taconator-witness, blckchnd, sahkan-bitshares, openledger-dc, sc-ol, billbutler-witness, delegate-zhaomu, hertz-feed.

Actively publishing price feeds:
wackou, delegate.ihashfury, verbaltech2, roelandp, taconator-witness, blckchnd, sahkan-bitshares, sc-ol, delegate-1.lafona, hertz-feed.

Not publishing price feeds yet:
fox, xeldal, xman, abc123, xn-delegate, datasecuritynode, bhuz, delegate.freedom, elmato, in.abit, witness.yao, witness.still, openledger-dc, billbutler-witness, delegate-zhaomu

We may need to increase the max price feed publisher quantity again unless I start swapping above approved (and inactive) price feed publishers for willing parties.

Cheers,
CM.

I've been working on getting the HERTZ Algorithm Based Asset live on the Bitshares network recently, and ran into problems providing more than 10 private price feed publisher entities (Rather than witness|committee fed).

Would it be possible for the committee to increase the 'maximum_asset_feed_publishers' value from 10 to say 25?

As far as I'm aware, there's no risk associated with increasing this value, right?

General Discussion / Bitshares HUG REST API
« on: December 27, 2017, 03:24:07 am »
Hey,



I've created a REST API using HUG for Bitshares over the last few days. You can't control the wallet, but you can access all data on the blockchain through get requests now.

It's fully open sourced & documented in a manner to improve ease of implementation.

Would you use this tech?

Stakeholder Proposals / BSIPs 23 & 24
« on: August 29, 2017, 11:15:55 pm »
I've created two draft BSIPs:

BSIP-0023 - Sharedropping an UIA against an external cryptocurrency distribution snapshot
https://steemit.com/bitshares/@cm-steem/draft-bsip-0023-sharedropping-an-uia-against-an-external-cryptocurrency-distribution-snapshot

Draft BSIP-0024 - "Locking Bitshares away as 'Bitshares Influence' for voting privileges on the BTS DEX"
https://steemit.com/bitshares/@cm-steem/draft-bsip-0024-locking-bitshares-away-as-bitshares-influence-for-voting-privileges-on-the-bts-dex

I'd appreciate input on both, they're drafts and haven't been submitted as a pull request into the BSIP repo yet.

Thanks +5%

Technical Support / Updated Bitshares client on official website?
« on: August 03, 2017, 12:52:12 pm »
Hey,

Several users have been asking for an updated bitshares client update on the bitshares.org website, the last client release was 22nd may. Who is in charge of bitshares.org and or release management?

Cheers

Hey,

Is there any documentation on how to take a snapshot of a bitcoin based blockchain as the basis for an new graphene blockchain's initial supply sharedrop?

It could help altcoins migrate to graphene in the future..

Best regards,
CM.

Can anyone provide a working example of the get_market_history CLI command please?

I've been unable to provide the command valid input data, I keep getting error messages about ISO time formatting (despite attempting to use such formatting).

I'm wanting to dump the market history for the MPA/BTS trading pairs & summarize market making participation using Hadoop, potentially incentivizing market making activity (filled orders only, select trading pairs).

Side note: I think it'd be a great idea to provide a single working usage example for each documented API command, this would significantly improve the ease of learning the CLI commands.

Docs API content:
Code: [Select]
vector<bucket_object> graphene::app::history_api::get_market_history(asset_id_type a, asset_id_type b, uint32_t bucket_seconds, fc::time_point_sec start, fc::time_point_sec end) const
Reference:

Thanks,

CM.

General Discussion / Bitshares UI Customization Guide!
« on: July 02, 2017, 04:48:19 pm »
Hey,

Fuzzy contacted me on Telegram regarding the potential development of customized web wallets, so I created a draft guide regarding how to customize the Bitshares UI. The aim of this guide is to provide a fast on-ramp for new UI developers.

The guide covers the dev environment setup, editing the header/footer, changing the featured trading pairs throughout the UI and how to create new themes.

I'd greatly appreciate input on the guide, it's open source & MIT licensed on GitHub so it's open to the community to aid its development:

General Discussion / CFETS MPA?
« on: May 22, 2017, 03:00:12 am »
I like the look of ALTCAP.XDR because it's a basket currency by the IMF, but it's only applied against 5 currencies. https://www.imf.org/external/np/fin/data/rms_sdrv.aspx

The CFETS basket currency by comparison is based on 24 currencies: http://www.chinamoney.com.cn/english/svcnrl/20161229/2047.html

Do you think there would be interest in an MPA based on CFETS?

General Discussion / HERTZ - Oscillating Formula Based Asset
« on: May 17, 2017, 07:27:47 pm »

What is Hertz?

Hertz is a highly experimental Market Pegged Asset (MPA) created on the Bitshares network. Elected Bitshares witnesses will publish price feeds which are pegged against the United States Dollar (USD) and predictably oscillates using a sine wave algorithm. The sine wave has an amplitude of 14% and a period of 28 days, thus the price feed value changes 2% every day and a resulting max price feed value of $1.14 and min of $0.86 (Note: Depending on the combination of Bitshares price volatility and age of price feeds published by witnesses, these limits may not always hold).

Hertz tokens are shorted (borrowed) into existence by users on the Bitshares network with at least 175% backing collateral in Bitshares; there is no centralized issuance and asset creator permissions have been restricted for increased decentralization.

By implementing a sine wave phase offset (date/time), we are able to make each Wednesday (mid working week) the most important day for Hertz.

Price feeds:
Reference Python scripts & calculator (https://github.com/BTS-CM/scripts)
  hertz_calculator.xlsx : A spreadsheet for evaluating the effect of different sine wave variables (amplitude, period, etc).
  hertz-verification.py : Used for verifying that the phase offset lines up appropriately.
  hertz-feed.py : What you'd use if you don't use wackou or xeroc's price feed scripts.
Wackou's 'BTS_Tools' (Only use if pull request #36 is merged, OR if you change 1/3 to 0.14 yourself manually).

Xeroc's 'Bitshares-PriceFeed' (Issue #25 addresses the inaccurate amplitude comments)
  https://github.com/xeroc/bitshares-pricefeed/blob/master/bitshares_pricefeed/examples/hertz.yaml

Surrendered FBA settings
- Disable confidential transactions:
- Require holders to be white-listed:
- Issuer may transfer asset back to himself:
- Issuer must approve all transfers

TODO
- Get witnesses to publish price feeds for the Hertz MPA
