Bitcoin Wrapped In Ether – Yummy!

You can take two good things and combine them together to get the best of both. In LA’s streets you can get what some would consider one of the city’s iconic sandwiches. It is the hotdog wrapped in bacon. It brings you the meaty flavor of a hotdog with the greasy goodness of bacon. Now think about the top digital asset Bitcoin (BTC). What would you wrap it with if you were to compare it to a hotdog wrapped in bacon? How about Ether (ETH), the Ethereum blockchain’s token. BTC is your hotdog, while ETH is your bacon. It actually exists and it is called Wrapped Bitcoin (WBTC).

Wrapping one cryptocurrency with another uses the hotdog wrapped in bacon example as a simpler way to illustrate an analogy. Wrapping in this sense means to create a protocol to represent one cryptocurrency on another cryptocurrency’s blockchain. BTC can be represented on the Ethereum blockchain by issuing an ERC-20 token called WBTC. This allows BTC integration with smart contracts that can be traded on the Ethereum network using the ERC-20 standard.

In Wrapped Bitcoin, BTC is locked into a smart contract and issued as WBTC. This allows BTC holders to access DeFi systems on the Ethereum blockchain. It is as good in value as BTC which is verified by a Proof-of-Reserve system. This ensures a 1:1 peg between the issued or minted WBTC tokens and BTC. The actual BTC is still on the Bitcoin blockchain since you cannot store it on the Ethereum blockchain. The BTC is taken under the custody of the WBTC token issuer, so it is not directly with the WBTC token holder. It is maintained by a group called the WBTC DAO, who are the custodians of the BTC. The group’s members include blockchain-based organizations like BitGo, Ren and Kyber.

What is the purpose of WBTC?

As mentioned earlier, it is primarily for giving BTC holders a way to gain access to the DeFi markets. A large portion of the DeFi space uses the Ethereum blockchain and BTC is not directly compatible with it. It is a bridge that allows BTC holders to use DeFi protocols to provide liquidity or participate in other services that yield returns. WBTC is a way to bring the value from BTC into the DeFi space without having to convert BTC to ETH. BTC (as of 2020) has the largest cryptocurrency market cap and this is crucial in helping bring liquidity to the DeFi space as well as expanding on the collateral types available.

This is a great way for BTC holders to take part in the DeFi markets. Many BTC holders have plenty of value stored, but are not able to use it if they are HODLing. DeFi provides ways for cryptocurrency to earn even while HODLing, using decentralized protocols like Uniswap, Curve and Yearn. Most DeFi protocols will only support ERC-20 or ETH since they execute from smart contracts on the Ethereum blockchain. WBTC is a protocol that allows BTC to be wrapped in an Ethereum ERC-20 token. Holders would not need to convert their BTC to ETH during this process.

Minting WBTC

To enter the DeFi space, Bitcoin holders would have to deposit their BTC into a smart contract of a WBTC issuer (e.g. BitGo, Coinsquare, etc.). This can be a digital exchange or DEX (Decentralized Exchange) that accepts BTC. Once the BTC has been deposited, WBTC tokens are minted that have a 1:1 value to the BTC that was deposited. Once the holder receives their WBTC, they can now use it for loan collateral, providing liquidity and swapping for other tokens. Digital exchanges will most likely require a KYC (Know Your Customer) in compliance with the law before the WBTC can be issued. On a DEX or over-the-counter it is not required (check with the exchange requirements always). The WBTC can be cashed out to either BTC or ETH.

Another way to get WBTC is through a DEX like Uniswap. Instead of depositing BTC into a smart contract, anyone who holds ETH can purchase WBTC. It requires connecting a digital wallet like Metamask to perform the transaction with ETH. The WBTC is already available in the market and it does not require BTC for purchase in this case. Since WBTC is an ERC-20 token, it can be purchased with ETH very easily.

Other Uses For WBTC

WBTC can be put to use in DeFi yield farming protocols. This allows WBTC holders to put their digital asset for lending and trading purposes. In return, the WBTC holders earn yields as a their return on investment. These yields are fees collected from the transactions. Rewards can be issued in the form of governance tokens, which allow the holders to participate in digital governance through voting. This provides holders a way of participating in decisions that govern these protocols.

Yield farming requires the holders to deposit their WBTC. In return, they are issued another token. Examples of these tokens include SNX (Synthetix token), REN (Ren Project token) and BAL (Balancer token). The tokens are specific to which protocol is used by the yield provider. To learn more about yield farming, there is an article on Coindesk that explains it a little bit further. (Link here)

The Best Of Both

Wrapped Bitcoin brings the best of two blockchains. It is a way to interoperate between two digital assets at the protocol layer. The value of Bitcoin and the decentralized applications on Ethereum. BTC is the digital asset while ETH is the protocol that utilizes it for liquidity, trades and financing. The Ethereum blockchain is serving as a transaction layer that can bring more capital into diverse markets. Bitcoin can provide the capital, as institutional investment grows in the digital asset. WBTC provides a way for investors to bring capital for yielding returns using the Ethereum blockchain.

Coinbase Goes Down When Bitcoin Goes Up

It seems there is a correlation to Coinbase having network issues every time there is a Bitcoin bull run. It just appears to be a certainty at this point:

“When Bitcoin goes up, Coinbase goes down”

During the Bitcoin rally in 2017, when Bitcoin price value approached an ATH of $20K, Coinbase also experienced connectivity issues and trading was halted. This was the time Bitcoin suddenly surged and then came crashing down as soon as traders hit the exchange. It seems that the Coinbase system was not designed to accommodate or scale to handle millions of new users. That should have been a lesson to resolve the problem over the years.

It has not been solved. The most recent bouts of network outages and downtime have been occurring on and off. Between March and November of 2020, Coinbase has had a series of problems with their network. It may have affected the trading of Bitcoin in some way or another. No one is reporting the exact reason for these problems, but there have been reports of outages from Coinbase’s cloud provider AWS.

During a brief Bitcoin surge in November 2020, and also during an XRP rally, Coinbase suddenly goes down. It is frustrating traders who could have sold or bought more assets, but instead the system crashes. If it were a universal problem, it would also happen at the same time to other exchanges like Binance and Kraken. They all have to deal with issues on the network, but never at the level of Coinbase.

Coinbase CEO, Brian Armstrong, tweeted (in response to the problems):

“We’re working hard to add additional capacity (both in servers and customer support) to deal with increased traffic. Thank you for your patience during this time. And thank you to the team at Coinbase working hard to serve our customers! Bull runs can be exciting and stressful.”

From an IT and network engineering perspective, the problem has to do with scalability and contingency. While AWS has autoscaling capabilities, if the whole infrastructure is affected, it will have an effect on Coinbase. There are other cloud IaaS (Infrastructure-as-a-Service) providers like Microsoft Azure and Google Cloud, which allows operations to continue in the event that one provider is down. For contingency, a more distributed and decentralized system would have kept the system operational to handle enormous workloads. Perhaps Coinbase had planned for capacity, but not agility.

A more distributed system can prevent downtime, but doesn’t totally eliminate it. If a server malfunctions it will go down and there is nothing that can be done to prevent it. However, the contingency in place is to plan for fault-tolerance and redundancy. Other IT professionals have aired the same opinion, like Hashoshi on his “404 Logic Not Found” section.

Coinbase has been a pioneer in the cryptocurrency space. It would be sad to see their trading business affected by downtime and outages. They have enabled millions to get into cryptocurrency as an onboard to more decentralized financial instruments. There are more options available for traders to buy/sell crypto, including the Robinhood app and even PayPal. They still need exchanges like Coinbase to convert cryptocurrency. Hopefully they can work things out, or else traders will flock to other digital exchanges or DEXes for their business.
