I still remember when I first entered the encryption industry, the word public chain is a very high thing.
Because when people mention the public chain, they often think of the “universal smart contract type”, or platform-type public chain, such as ETH, rather than the “one currency, one public chain” public chain like BTC and LTC. These, we The definition of them in my heart is “Coin”.
At that time, every platform-type public chain was launched, which attracted much attention. From the earliest NEO, to later EOS, and later Solana, everyone attracted enough attention and rose to the sky. After all, “the world suffers from ETH.” It’s been so long” (it was too slow at the time…).
Now, the public chain has entered the rhythm of explosion and even flooding, such as LTC, Monero, the old style of one coin and one public chain has long been ignored, and the new one coin and one public chain basically refers to the type of Cosmos Appchain. . The platform-type public chain is also dozens of large if you count it casually. If you count it carefully, it is estimated that it can reach the rhythm of three digits.
Building a public chain has become so easy? Yes, no.
You are right, because it is really fast to open a public chain now. Gavin Wood used Substrate to start a chain in 15 minutes, and Avax used the command line to start a subnet in 42 seconds… In all kinds of chain issuance tools With the support of , the difficulty of building a public chain is much lower than before.
But does building a public chain just let him run and it’s over?
Of course not, there are still a lot of things waiting for you later, the public chain running is just the beginning.
01
hard first
1) Wallet
The beginning of everything is difficult. If you want a public chain used by others, the first step is to have a wallet.
The current public chain and wallet are completely polarized . EVM-compatible ones are like various OP series L2, Fantom, Polygon, etc. Just add a network to the little fox, but non-EVM-compatible ones are not that simple. , you must have your own “wallet ecology”, or “faucet wallet”, and the experience must be done well .
At this point, Solana and Cosmos are undoubtedly the best two, Phantom and Kelpr experience are not too good.
There are too many negative teaching materials, the earliest NEO, later EOS, and now Polkadot and ICP, either the wallet is extremely difficult to use, or various anti-humanity settings, or there is no standard or kill until now. There is no one leader… In short, the wallet experience sometimes directly affects the prosperity of a public chain ecosystem.
2) RPC node
The earliest Bitcoin and ETH players had to set up a full node when using wallets.
Now that the blockchain is gradually popularized, and naturally few people do this, so everyone’s operation requests on the wallet are directly forwarded to the RPC node (RPC refers to the service related to the interaction with the EVM-compatible public chain) , and this A piece is actually relatively centralized.
The vast majority of public chains are using RPC nodes provided by two node service providers, Infra or Alchemy, so once the servers of these two service providers fail, the public chain itself will often be greatly affected. There are also centralized ones, such as Pocket Network, but unfortunately it is still very early, a bit like the EtherDelta era of the earliest Dex!
RPC nodes belong to the infrastructure that is usually invisible to everyone, but if something goes wrong, it will directly affect the user experience. The most famous one is probably the Harmony chain, because RPC nodes are garbage on Discord and Twitter every day. scolded by users…
3) Block Explorer
I think that every user who plays Defi has never used Etherscan.
Compared with the behind-the-scenes feeling of RPC, the block explorer is real at the same time for DAPP and users, and its use experience also greatly affects the user’s experience of the entire chain.
After all, the main point of the blockchain is trustlessness, transparency, and the ability to query these features, and these things have to be presented to you by the block browser.
So after a new public chain comes out, I often look at two points when testing and experiencing, one is the wallet, but often I can’t see anything on the EVM compatible chain, because it is all Metamask. Therefore, what can better reflect the technical capabilities of a chain is how well the block browser does, which is also the second point I see.
4) Computing power equipment (Optional)
This, basically the new generation of public chains does not need this stuff, but at that time a few years ago, various POW chains were hyped up, and various computing power equipment was also sold happily.
The new generation of public chains is still insisting on POW. I only know Nervos and Kadena, and even ETH has been converted into POS. Enough to see the general trend.
Of course, you can still see some POW veterans on Twitter or various Chinese media, and they take the trouble to explain the advantages of POW over POS in decentralization, technology and other aspects. In my opinion, what they say is likely to be true, but it doesn’t matter. Just like when the MP3 player was born, you can discuss the CD sound quality from all angles to kill MP3, and in this market, it took MP3 just a few years to completely kick out the CD, and then MP3 was used in the 4G era. replaced by mobile cloud music. The market has never been technically deterministic. If you can see the trend clearly, you can avoid many pitfalls.
The author is still the same view that in the long run, we have and should have only one POW chain, that is BTC.
02
say soft
1) Token standard
You may first think of Defi kits, Dex, borrowing, stablecoins and the like.
These are of course important, but they still only rank second.
The first one should be the Token standard, which is the most important!
If a public chain does not issue Tokens, or the above ecological projects do not issue Tokens, what else are you playing? Just play the alliance chain.
The reason why ETH is so powerful is due to many ERC standards. The two most famous ones, ERC20 and ERC721, directly set off two big waves of 2017 ICO and 2021 NFT.
Therefore, when a new public chain is launched, it is essential to have a relatively unified Token standard for ecological prosperity.
The negative teaching material for this point is undoubtedly ICP. The mainnet has been online for more than a year, but there is still no official Token standard, resulting in the entire ecosystem being basically in a state of “no Token available”. Perhaps the earliest official idea was to submit the standard to For developers and users, a set of standards was freely fought in the “Jianghu”, and later found that this road was not feasible. Finally, in August this year, there was a “quasi-official” homogenized Token standard of ICPC-1.
2) The five major pieces of Defi – Dex, borrowing, stablecoins, oracles, bridges
It used to be three pieces, but now the basic oracles and bridges are also standard, so we put together five pieces.
-
Dex
The most important one is that almost all new public chains have no Swap. Of course, it is basically either Fork Uni or Sushi. This is equivalent to the trading platform of this public chain, which is naturally a top priority.
-
Metonymy
This is equivalent to a commercial bank, which ranks second in importance and cannot catch up with Dex. First, the value capture is not as good as Dex, so the income is not compared with Dex. Second, it is a new chain, and the demand for borrowing is often not high. No, no, no, but almost no one cares about borrowing, whether it is the old Kava or the new generation Umee, it is a rhythm that no one cares about.
-
stablecoin
It is best to have a native stablecoin, but this usually requires you to become bigger and stronger in order to attract the attention of Tether or Circle and introduce USDT or USDC into the ecosystem. Before that, you can only use bridges from “Borrow” on the ETH side. UST was an exception at first, but unfortunately it collapsed…
-
Oracle
At first, many public chains wanted to work hard or toss themselves, but now they have basically given up their struggles. Isn’t the ready-made Chainlink there?
-
bridge
The import and export of various stable coins and mainstream assets, the super hardest hit area of hacking incidents, but it is absolutely necessary. The Cosmos ecology has a lot of advantages in this regard, because there is no need for bridges in the ecology, and IBC transfers directly. Only when ETH or other chains are involved, the bridge is required.
3) NFT and Domain Name
This trend was not seen last year, and this year it has almost become the standard for all public chains.
Each chain basically has its own NFT similar to Punk or monkey. Of course, the price is not comparable to that of real Punk and monkey. The only remarkable thing should be the Solana NFT ecosystem. There are high prices such as Degod. NFT, and the MagicEden NFT market that is trying to catch up with Opensea.
In addition to NFTs, this year, domain names have gradually become standard in infrastructure, led by ENS.
Now we have .eth .sol .bit .bnb .etc .icp .dot .evmos… I believe that in the near future, each public chain will have its own corresponding domain name suffix to facilitate users to manage and use addresses.
Finally, friends, if you also think of other public chain infrastructure directions, welcome to discuss and exchange in the message area!
