Hi everyone! Here’s your week at Parachute + partners (27 Sep - 3 Oct'19):submitted by abhijoysarkar to ParachuteToken [link] [comments]
ParGas went live this week. From now on, you will get an additional option to pay for gas in $PAR when making ERC20 withdrawals from ParJar. Epic! Read all about it here. In this week’s Parena, Samuel defeated Martha in a quick finale to take home the lion’s share of the 100k $PAR pot. The #PAR4PAR contest entered stage 4. 200k $PAR in prizes. Insane! In this week’s Tiproom trivias, Ridwan hosted a 10 question quiz for 25k $PAR in total. There was another Math trivia for 25k $PAR more. Sweet! Doc Victor hosted a Champions League wager for 50 participants with a 10k $PAR pool.

Tiproom #mememania winners. Alimam and Rogel were tied in 1st place
The winner of the USD 500 BTC aXpire contest was announced this week. Congratulations to yo*******[email protected]! Rohit and my article on how Big Co and Big Guv is using blockchain was published in Altcoin Magazine. Week 39 update from the aXpireverse can be seen here. The weekly 20k $AXPR burn went ahead like clockwork. The latest 2gether app update now allows you to send $BTC and $ETH from your account to any wallet. Noice! The team, in the midst of shifting offices, set up camp at South Summit where 2gether is one of the finalist startups. Click here, here and here for pictures. As a finalist at the Summit, CEO Ramon got the opportunity to deliver a pitch to attendees. Plus interviews by Emprendiendo.TV and Funontheride. Great! The WednesdayClub dApp continues to airdrop $WED tokens every Wednesday. Make sure to get in on the action.
Parachute HQ recently shifted to the WeWork Navy Yards in NYC. Beautiful
XIO’s Binance Dex listing proposal* was submitted this week. For listing on the Dex, all projects submit detailed proposals and answer questions from the Binance Node operator community who then evaluate and decide on the listing. Read more about it here. Plus, there’s a hint of an $XIO doubling opportunity in there. The full roadmap (XIO Atlas) was also released with the proposal. An updated promo video came out as well. $XIO distribution to the giveaway winners was completed this week. In this week's discussion threads, Zachary talks about leverage, ERC20-BEP2 bridge, XIO capital and how many native tokens will incubated startups share with XIO citizens. The $BOMB Instagram is now handled by the community. So the BOMB Board opened up a proposal form for opinions from the community on how best to manage it.
\[As shared in last update, the switch to Binance Chain has been shelved. $XIO will stay on Ethereum. But there will still be a token swap. Details will be shared in a later update]*
Two updates back we saw the WIP version. Here’s the full version of XIO Atlas
The $ETHOS token will be rebranding to Voyager ($VGX). The new token will be unveiled in November. Please note that there is no contract swap. This will simply be a rename. You can read more about it here. The bitcointalk Ann goes into even more details on the rebranded token’s use-cases. Understandably, there were lots of questions that came up. So the team arranged an AMA. If you missed it, check out the FAQ. Voyager also received investment from Thrust Capital through a private placement this week. Nice! Congratulations to Bounty0x for getting accepted to the Berkeley Blockchain Xcelerator program. This is huge! The latest update is a great summary the past quarter @Bounty0x – reaching minimum fund raise goal on Republic, new features like Admin Notes, $BNTY staking, integration with Bloom and KABN etc. Fantom hosted an AMA with G.Crypto this week. CMO Michael shared a formalised roadmap article as well to answer all “when” questions. Plus, click here for some cool pics from CryptoBazar Serial Hacking meetup which the $FTM team attended. Uptrenndians, don’t forget to read the $1UP tokenomics update. It explains how the token velocity will work in a way such that everyone gets an equal opportunity at stacking $1UPs no matter when they join. BTW, if you didn’t notice yet, Uptrenndian made it to the Urban Dictionary. You can vote to keep it there forever. Let’s go! One way to beat Monday morning blues is a healthy dose of Meme Mondays while watching the site climb up the Alexa rankings. Haha. And finally, the team announced a partnership with Xord who will work on the blockchain solutions on the platform.

Mycro conducted KYC for bounty hunters and started a campaign to stop fake entries. OST-backed Pepo app moved to the first live beta stage this week as a precursor to a formal beta launch and presentation at Ethereum DevCon5 in Osaka next week. The team also shared details of how to hop in for a free Shabu Shabu dinner and pub crawl for Pepo beta users at DevCon5. And on top of that, a massive bounty for sharing IRL experiences on Pepo. Dang! Another bounty for usability testing of Pepo with the UX Team was also launched. 3k $OST for each selected participant. Say what! The OST-backed LGBT token now has 4k+ users thanks to the Hornet app. Well done! SelfKey announced a partnership with social watching platform Livetree for providing them KYC compliance solutions during onboarding process. Make sure to read the post to find out how to get a 90-day free subscription on the platform. If you haven't yet watched Constellation advisor and former Sanrio CEO Ray Rehito Hatoyama's interview with Co-Founder Benjamin Jorgensen, you can read about it in The Daily Chain's detailed coverage. If you're a $DAG node operator, this tweet will be of interest to you. Hint: onboarding has started. Folks who missed Constellation's AMA with tehMoonwalkeR can catch up from the transcript. And finally, Arena Match hosted a flash giveaway. Eagle eyed fans got their hands on some sweet $AMGO!
Pepo ready to make waves at DevCon5
The month gone by at Opacity saw a 20% increase in new accounts and a ~20% return rate on the site. Read more performance metrics from CEO Jason’s round up article. This month will see a slew of new features like integrated gift card payments, plan upgrades, folder upload etc. A productive community doesn’t stop BUIDLing. Check out ImgOpq which is a community run imageboard that works with public Opacity handles. Fun! Catch up on the latest at District0x from the weekly and dev update. Plus, a shoutout to Ethlance from Jaide of Cryptalk was pretty cool. More partners joined the Hydro dApp store this week including Temporal, MESG and Colony. Hydrogen won the USA Nationals of the BBVA Open Talent Award which is one of the world’s largest fintech startup competitions. As a result, the team won the opportunity to present at the BBVA Open Summit in Madrid. Co-Founder Mike travelled to the World Blockchain Forum Conference in NYC to speak on Libra vs Hydro and data privacy. The South African Reserve Bank shortlisted Hydro for an accelerator programme in South Africa which will culminate in a Demo Day at the end of the month. Two winners from the Demo Day will be chosen who will get to pitch at the Singapore Fintech Festival and receive funding. Good Luck! To read a quick dev update, click here. The Sentivate community voted on whether to burn $SNTVT tokens or host a raffle. One way to participate in the vote was by signing a message through one’s wallet. How? Read this to find out. Chico Crypto’s deep dive interview with Founder Thomas Marchi was released this week. Continuing with last week’s discussion on universal domain system, this week we learned about how Domain Information Service works in the Universal Web.
And with that, it’s a close for this week at Parachute. Cheerio!

Coinbase may have to transfer all European accounts if the Brexit agreement cannot be reached If the Brexit agreement cannot be reached, Coinbase, one of the largest encrypted exchanges in the United States, may have to transfer all European accounts to another authorized entity within the EU. Currently, Coinbase operates an e-money institution called CB Payments in the UK, which is licensed by the Financial Market Conduct Authority (FCA). CB handles digital currency payment transactions from the European Economic Area (EEA). In an email to European customers, Coinbase warned that they might have to close CB Payment Ltd if they did not reach the Brexit agreement. The company also guarantees that the Coinbase services used by these accounts will not be affected during the transfer. The email also mentioned that the time of the transfer has not yet been determined, but if there is a need for a transfer, they will notify the user in a timely manner.
Project submission code ranking week list: Istanbul hard forks soon, Ethereum code changes frequently According to Coingecko data, as of September 1, Chainlink (LINK) code submissions jumped to the top in the past four weeks. Last week, Holo topped the list with a slight disadvantage, while Lisk (LSK) remained in second place. Then the fourth to tenth names are: aelf (ELF), Bitcoin (BTC), Aeternity (AE), 0x (ZRX), Bitcoin Cash (BCH), Maker (MKR), Status (SNT). The actual change in the code this week has not changed significantly from the previous two weeks. According to the data, perhaps due to the hard fork of Istanbul, Ether Square (ETH) code submission and replacement is very frequent in the past two weeks. In the past four weeks, Ethereum (ETH) added 301,396 lines of code and 4559 code removed to lead other development teams, ranking first. The developer of the 0x (ZRX) protocol is still eager to add 128,750 lines of code and 31,382 lines of code to delete the second. The Monroe coin, which ranked second in the last week’s change, is no longer on the list this week. The first two digits of the code submissions, Chainlink (LINK) and Lisk (LSK), are equally valuable and quality, and ranked third and fourth in the code change rankings this week. Holo (HOT) didn’t even have the top 10.
Facebook’s Libra Might Fill Bitcoin’s Void As A Payment Network, Suggests Arba’s CEO In a recent What Bitcoin Did podcast, Bill Barhydt, CEO and founder of cryptocurrency wallet and exchange, Abra, shared his views on Libra. Bill Barhydt began the segment by pointing out that Facebook still has a large user base despite being known for its privacy-related issues. He detailed how an average consumer lacked an understanding of the importance of privacy. Perception of an average consumer on privacy completely shifts after being hacked, he added. Barhydt further detailed how Facebook might have considered using Bitcoin and then came to the conclusion that Bitcoin is “not optimized correctly” to be a payment network but is optimized to be “digital cash.” He added, “I think there’s a huge belief in the Bitcoin model, but I also think there was a recognition that given the problems, the explicit problems they’re trying to solve, there was no way that Bitcoin was going to work for them for this.”

In the last weekly forecast, we discussed the possibilities of a downward move below $10,000 in bitcoin price against the US Dollar. The BTC/USD pair did move down and broke the key $10,000 and $9,800 support levels. Moreover, there was a close below the $10,000 pivot and the 100 simple moving average (4-hours). Finally, there was a break below the $9,800 and $9,500 supports as well.
A new monthly low was formed near $9,300 and the price is currently consolidating losses. It is testing the 23.6% Fib retracement level of the recent decline from the $10,717 high to $9,308 low. However, there are many hurdles on the upside near the $9,800 and $9,900 levels. Additionally, there is a major bearish trend line forming with resistance near $9,980 on the 4-hours chart of the BTC/USD pair.
Moreover, the 50% Fib retracement level of the recent decline from the $10,717 high to $9,308 low is also near the $10,010 level. Therefore, upsides are likely to remain capped near the $9,800 and $10,000 levels. Above the trend line, the 100 SMA is waiting near the $10,150 level. The 61.8% Fib retracement level of the recent decline from the $10,717 high to $9,308 low is also waiting near the $10,170 level.

On the eve of the release on the mainnet, the team of the cross-chain wallet Swap Online is publishing a research study and the code of the atomic swapusing USDT.
USD Tether — the equivalent of the dollar on Omni LayerThe solution described above with the protocol “over” the Bitcoin network gave life to one of the most controversial cryptocurrency projects of the last two years — Tether. Tether (symbol Tether — ₮, ticker — USDT) is a hybrid cryptocurrency with a rate binding to one US dollar. Moreover, according to the assurances of Tether Limited, the issuer of the given tokens, the “binding” is to be understood literally, as each purchased token of USDT corresponds to one US dollar available at the disposal of the company.
If we take the three largest exchanges based on their daily turnover of transactions at the time of writing (Binance, OKEx and HuObi), and then track the five most popular trading pairs for each, we will encounter USDT in 13 out of 15 cases.
USDT — the token with the largest capitalization in the world.All this generates great community interest in faster, safer and cheaper solutions for exchanging Tether into other currencies. Obviously, such a solution could be atomic swaps, which are instant, decentralized cross-chain exchanges. The Komodo laboratory, the main headliners of this technology, who presented it in the autumn of 2017, reported on the successful exchange of KMD to USDT carried out on the BarterDEX platform, Komodo’s own exchanger.
At the same time, according to our data, the developers of Komodo made a swap on the ERC20-a version of Tether, which is only available in 3% of cases. Approximately 60 million USDT from global turnover can thus be exchanged using this method, which, obviously, cannot be considered as a solution to the problem. Striking examples of imperfections of existing solutions can be found even on Etherscan.
This fall, the team of Swap Online is ready to present an atomic swap with Tether. And here’s how we did it.
How Omni conducts transactionsTo carry out the Omni transaction, a user needs to create a regular Bitcoin transaction-transfer of 546 satoshi (minimum) with an additional output storing payload using the OP_RETURN op-code. An example of such a transaction. The payload is a mandatory part of any Omni transaction, as it is a sequence of bytes containing all the necessary information about the transaction.
Let us consider what information is stored in the payload itselftransaction marker — 4 bytes, the mandatory part of any Omni payload is always equal to 0x6f6d6e69 — ASCII code omni. If the first 4 bytes of the sequence are not equal to 0x6f6d6e69, then this sequence is not a payload of Omni.
version — 2 bytes, an analog version of the transaction in Bitcoin. For the described algorithm to work, version 0 is used, or that is the same as 0x0000.
transaction type — 2 bytes, transaction type, for an atomic swap it is sufficient to use only “Simple send” transactions, as simple send is the usual sending of omni currency from its address to the address of the recipient. Simple send corresponds to the transaction type code 0, that is, the next 2 bytes 0x0000. Other possible types of transactions exist in Omni.
token identifier — 4 bytes, identifier of the currency used. For example TetherUS has the identifier 31 or 0x0000001f. All tokens created by the Omni protocol at this time can be seen via the following link.
amount — 8 bytes, for a transaction of type Simple send, this is the amount of the sent currency.
As you can see, payload does not store the addresses of senders and recipients of the transactions, these addresses are determined by the Bitcoin transaction in which the payload output was detected. By scanning inputs, the Omni protocol determines who makes the transfer by finding the output of the corresponding address from among the inputs of the transaction p2pkh.
Thus, for a transfer from Alice to Bob of, for example, 50,000,000 TetherUS, we need to create a Bitcoin transaction where one of the inputs will refer to the p2pkh output corresponding to the Alice address. It is also important that this entry be the first in this transaction (the index of this entry in the received transaction would be is minimal or none at all). One of the outputs of this transaction should be the output of p2pkh to Bob’s address, and another output must have been one of the outputs with the following payload:
Atomic Swap on Omni LayerSuppose that Alice and Bob are willing to make an inter-blockchain exchange of cryptocurrencies. Alice wants to exchange the units of any Omni currency, for example TetherUS (the given currency has the currency identifier # 31 in the Mainnet, then in the text we will only talk about this currency of the Omni protocol, since it is the most popular at the moment, but the algorithm below will work for any currency of the Omni protocol as well) for b units of a cryptocurrency working on another blockchain. (Omni works on top of the Bitcoin blockchain, of course, according to the algorithm below it is possible to exchange TetherUS for Bitcoins, but due to their work on one and the same blockchain, this exchange can be done in a different, more efficient way).
GlossaryA — blockchain of Bitcoin.
B — the blockchain of the cryptocurrency for which TetherUS is being exchanged.
a — the sum of TetherUS, which Alice wants to exchange.
b — the sum of the cryptocurrency of the adjoining blockchain B, to which Alice wants to exchange her a TetherUS.
Creating a Transaction1) Bob generates a random value secret.
2) Bob calculates the secretHash by performing the following operation: secretHash = RIPEMD160 (secret)
3) Bob creates and sends an htlc transaction sealed by secretHash
4) Bob sends Alice a secretHash value, and a hash of the hrlc transaction he created in the previous paragraph in order for Alice to make sure that the correct htlc transaction is actually present in the B blockchain.
5) Alice received from Bob the secretHash and hash of the htlc-transaction Bob created, and is convinced that such a transaction is really present in the B blockchain, and that this is indeed a htlc-transaction sealed by the secretHash value.
6) using the received secretHash, Alice creates the following transaction and translates it into the Bitcoin blockchain:
Let us call such a transaction financing_tx. In fact, it is almost an ordinary Bitcoin htlc transaction that is used in atomic swap with the only difference that in the amount field, 546 satoshi is the minimum number of Bitcoins that can be at the output of the transaction, below this value, Bitcoin counts the transaction as dust and does not conduct it.
7) Alice creates a transaction according to the following scheme:
Let us call this transaction redeem_tx. Alice creates such a transaction with two inputs: the first is the input referencing the output of funding_tx, which contains the htlc script. Alice does not sign this script, that is, the SigScript field remains completely empty. The second input is the input referring to any unspent exits of Alice, the main condition is that at this output stage there are enough Bitcoins to pay the transaction fee, and this entry is signed by Alice with her private key with the signature type SIGHASH_ALL (that is, she signs the entire transaction except for SigScript fields on the inputs transaction, which makes this transaction immutable. The outputs of the same transaction are the elementary Simple Send and a TetherUS from Alice to Bob (details of what Simple Send, payload is and how it works can be found in another section).
8) Alice sends Bob the redeem_tx created in the previous paragraph and the one she signed herself.
9) Bob got the redeem_tx sent by Alice, checks it, just looks through the inputs and outputs, making sure that this is really a transaction that Alice should have created using the real algorithm. After that, Bob signs the transaction with his private key and provides the secret value in the SigScript of the corresponding redeem_tx entry.
10) Bob sends the signed redeem_tx transaction to the blockchain, thereby transferring the TetherUS currency from Alice to himself. Note — before carrying out this step, we still need to check that Alice’s address has the necessary amount of TetherUS.
11) Alice looks through blockchain A and gets the value secret and uses it in the B blockchain to transfer the funds using the htlc transaction Bob created in point 3. The exchange ends here.
Stating the obvious: naturally the timelock value used by Bob when creating the htlc-transaction must be significantly longer than the timelock that Alice uses, since her htlc transaction should be spent earlier than the htlc created by Bob. This is necessary so that Bob cannot manage to spend both htlc.
ConclusionThus, connecting Omni Layer to Swap Online allows users to cover transactions.
